Enable more than 32 IRQs by removing the u32 bit mask in
iavf_irq_enable_queues(). There is no need for the mask as there are no
callers that select individual IRQs through the bitmask. Also, if the PF
allocates more than 32 IRQs, this mask will prevent us from using all of

In the event of a failure in tcf_change_indev(), u32_set_parms() will
immediately return without decrementing the recently incremented
reference counter. If this happens enough times, the counter will
rollover and the reference freed, leading to a double free which can be
used to do 'bad things'.
In order to prevent this, move the point of possible failure above the
point where the reference counter is incremented. Also save any
meaningful return values to be applied to the return data at the

Instead of relying on skb->transport_header being set correctly, opt
instead to parse the L3 header length out of the L3 headers for both
IPv4/IPv6 when the Extended Layer Op for tcp/udp is used. This fixes a
bug if GRO is disabled, when GRO is disabled skb->transport_header is
set by __netif_receive_skb_core() to point to the L3 header, it's later
fixed by the upper protocol layers, but act_pedit will receive the SKB
before the fixups are completed. The existing behavior causes the
following to edit the L3 header if GRO is disabled instead of the UDP
header:
tc filter add dev eth0 ingress protocol ip flower ip_proto udp \
dst_ip 192.168.1.3 action pedit ex munge udp set dport 18053
Also re-introduce a rate-limited warning if we were unable to extract

igb: Fix extts capture value format for 82580/i354/i350
[ Upstream commit
6292d7436cf2f0a2ea8800a1d2cbb155d237818a ]
82580/i354/i350 features circle-counter-like timestamp registers
that are different with newer i210. The EXTTS capture value in
AUXTSMPx should be converted from raw circle counter value to
timestamp value in resolution of 1 nanosec by the driver.
This issue can be reproduced on i350 nics, connecting an 1PPS
signal to a SDP pin, and run 'ts2phc' command to read external
1PPS timestamp value. On i210 this works fine, but on i350 the
extts is not correctly converted.
The i350/i354/82580's SYSTIM and other timestamp registers are
40bit counters, presenting time range of 2^40 ns, that means these
registers overflows every about 1099s. This causes all these regs
can't be used directly in contrast to the newer i210/i211s.
The igb driver needs to convert these raw register values to
valid time stamp format by using kernel timecounter apis for i350s
families. Here the igb_extts() just forgot to do the convert.

ping6: Fix send to link-local addresses with VRF.
[ Upstream commit

Ping sockets can't send packets when they're bound to a VRF master
device and the output interface is set to a slave device.
For example, when net.ipv4.ping_group_range is properly set, so that
ping6 can use ping sockets, the following kind of commands fails:
$ ip vrf exec red ping6 fe80::854:e7ff:fe88:4bf1%eth1
What happens is that sk->sk_bound_dev_if is set to the VRF master
device, but 'oif' is set to the real output device. Since both are set
but different, ping_v6_sendmsg() sees their value as inconsistent and
fails.
Fix this by allowing 'oif' to be a slave device of ->sk_bound_dev_if.
This fixes the following kselftest failure:

net: enetc: correct the indexes of highest and 2nd highest TCs
[ Upstream commit
21225873be1472b7c59ed3650396af0e40578112 ]
For ENETC hardware, the TCs are numbered from 0 to N-1, where N
is the number of TCs. Numerically higher TC has higher priority.
It's obvious that the highest priority TC index should be N-1 and
the 2nd highest priority TC index should be N-2.
However, the previous logic uses netdev_get_prio_tc_map() to get
the indexes of highest priority and 2nd highest priority TCs, it
does not make sense and is incorrect to give a "tc" argument to
netdev_get_prio_tc_map(). So the driver may get the wrong indexes
of the two highest priotiry TCs which would lead to failed to set
the CBS for the two highest priotiry TCs.
e.g.
$ tc qdisc add dev eno0 parent root handle 100: mqprio num_tc 6 \
map 0 0 1 1 2 3 4 5 queues 1@0 1@1 1@2 1@3 2@4 2@6 hw 1
$ tc qdisc replace dev eno0 parent 100:6 cbs idleslope 100000 \
sendslope -900000 hicredit 12 locredit -113 offload 1
$ Error: Specified device failed to setup cbs hardware offload.
^^^^^
In this example, the previous logic deems the indexes of the two
highest priotiry TCs should be 3 and 2. Actually, the indexes are
5 and 4, because the number of TCs is 6. So it would be failed to
configure the CBS for the two highest priority TCs.

netfilter: nf_tables: incorrect error path handling with NFT_MSG_NEWRULE
[ Upstream commit
1240eb93f0616b21c675416516ff3d74798fdc97 ]
In case of error when adding a new rule that refers to an anonymous set,
deactivate expressions via NFT_TRANS_PREPARE state, not NFT_TRANS_RELEASE.
Thus, the lookup expression marks anonymous sets as inactive in the next
generation to ensure it is not reachable in this transaction anymore and
decrement the set refcount as introduced by
c1592a89942e ("netfilter:
nf_tables: deactivate anonymous set from preparation phase"). The abort
step takes care of undoing the anonymous set.
This is also consistent with rule deletion, where NFT_TRANS_PREPARE is
used. Note that this error path is exercised in the preparation step of
the commit protocol. This patch replaces nf_tables_rule_release() by the
deactivate and destroy calls, this time with NFT_TRANS_PREPARE.
Due to this incorrect error handling, it is possible to access a
dangling pointer to the anonymous set that remains in the transaction
list.

netfilter: nf_tables: integrate pipapo into commit protocol
[ Upstream commit
212ed75dc5fb9d1423b3942c8f872a868cda3466 ]
The pipapo set backend follows copy-on-update approach, maintaining one
clone of the existing datastructure that is being updated. The clone
and current datastructures are swapped via rcu from the commit step.
The existing integration with the commit protocol is flawed because
there is no operation to clean up the clone if the transaction is
aborted. Moreover, the datastructure swap happens on set element
activation.
This patch adds two new operations for sets: commit and abort, these new
operations are invoked from the commit and abort steps, after the
transactions have been digested, and it updates the pipapo set backend
to use it.
This patch adds a new ->pending_update field to sets to maintain a list
of sets that require this new commit and abort operations.

spi: fsl-dspi: avoid SCK glitches with continuous transfers
[ Upstream commit
c5c31fb71f16ba75bad4ade208abbae225305b65 ]
The DSPI controller has configurable timing for
(a) tCSC: the interval between the assertion of the chip select and the
first clock edge
(b) tASC: the interval between the last clock edge and the deassertion
of the chip select
What is a bit surprising, but is documented in the figure "Example of
continuous transfer (CPHA=1, CONT=1)" in the datasheet, is that when the
chip select stays asserted between multiple TX FIFO writes, the tCSC and
tASC times still apply. With CONT=1, chip select remains asserted, but
SCK takes a break and goes to the idle state for tASC + tCSC ns.
In other words, the default values (of 0 and 0 ns) result in SCK
glitches where the SCK transition to the idle state, as well as the SCK
transition from the idle state, will have no delay in between, and it
may appear that a SCK cycle has simply gone missing. The resulting
timing violation might cause data corruption in many peripherals, as
their chip select is asserted.
The driver has device tree bindings for tCSC ("fsl,spi-cs-sck-delay")
and tASC ("fsl,spi-sck-cs-delay"), but these are only specified to apply
when the chip select toggles in the first place, and this timing
characteristic depends on each peripheral. Many peripherals do not have
explicit timing requirements, so many device trees do not have these
properties present at all.
Nonetheless, the lack of SCK glitches is a common sense requirement, and
since the SCK stays in the idle state during transfers for tCSC+tASC ns,
and that in itself should look like half a cycle, then let's ensure that
tCSC and tASC are at least a quarter of a SCK period, such that their
sum is at least half of one.

RDMA/rxe: Fix ref count error in check_rkey()
[ Upstream commit
b00683422fd79dd07c9b75efdce1660e5e19150e ]
There is a reference count error in error path code and a potential race
in check_rkey() in rxe_resp.c. When looking up the rkey for a memory
window the reference to the mw from rxe_lookup_mw() is dropped before a
reference is taken on the mr referenced by the mw. If the mr is destroyed
immediately after the call to rxe_put(mw) the mr pointer is unprotected
and may end up pointing at freed memory. The rxe_get(mr) call should take
place before the rxe_put(mw) call.
All errors in check_rkey() call rxe_put(mw) if mw is not NULL but it was
already called after the above. The mw pointer should be set to NULL after
the rxe_put(mw) call to prevent this from happening.

RDMA/rtrs: Fix rxe_dealloc_pd warning
[ Upstream commit
9c29c8c7df0688f358d2df5ddd16c97c2f7292b4 ]
In current design:
1. PD and clt_path->s.dev are shared among connections.
2. every con[n]'s cleanup phase will call destroy_con_cq_qp()
3. clt_path->s.dev will be always decreased in destroy_con_cq_qp(), and
when clt_path->s.dev become zero, it will destroy PD.
4. when con[1] failed to create, con[1] will not take clt_path->s.dev,
but it try to decreased clt_path->s.dev
So, in case create_cm(con[0]) succeeds but create_cm(con[1]) fails,
destroy_con_cq_qp(con[1]) will be called first which will destroy the PD
while this PD is still taken by con[0].
Here, we refactor the error path of create_cm() and init_conns(), so that
we do the cleanup in the order they are created.
The warning occurs when destroying RXE PD whose reference count is not
zero.

usb: dwc3: gadget: Reset num TRBs before giving back the request
commit
00f8205ffcf112dcef14f8151d78075d38d22c08 upstream.
Consider a scenario where cable disconnect happens when there is an active
usb reqest queued to the UDC. As part of the disconnect we would issue an
end transfer with no interrupt-on-completion before giving back this
request. Since we are giving back the request without skipping TRBs the
num_trbs field of dwc3_request still holds the stale value previously used.
Function drivers re-use same request for a given bind-unbind session and
hence their dwc3_request context gets preserved across cable
disconnect/connect. When such a request gets re-queued after cable connect,
we would increase the num_trbs field on top of the previous stale value
thus incorrectly representing the number of TRBs used. Fix this by
resetting num_trbs field before giving back the request.

The Qualcomm dwc3 glue driver is currently accessing the driver data of
the child core device during suspend and on wakeup interrupts. This is
clearly a bad idea as the child may not have probed yet or could have
been unbound from its driver.
The first such layering violation was part of the initial version of the
driver, but this was later made worse when the hack that accesses the
driver data of the grand child xhci device to configure the wakeup
interrupts was added.
Fixing this properly is not that easily done, so add a sanity check to
make sure that the child driver data is non-NULL before dereferencing it
for now.
Note that this relies on subtleties like the fact that driver core is
making sure that the parent is not suspended while the child is probing.

usb_udc_vbus_handler() can be invoked from interrupt context by irq
handlers of the gadget drivers, however, usb_udc_connect_control() has
to run in non-atomic context due to the following:
a. Some of the gadget driver implementations expect the ->pullup

b. usb_gadget_disconnect() acquires udc_lock which is a mutex.
Hence offload invocation of usb_udc_connect_control()
to workqueue.
UDC should not be pulled up unless gadget driver is bound. The new flag
"allow_connect" is now set by gadget_bind_driver() and cleared by
gadget_unbind_driver(). This prevents work item to pull up the gadget
even if queued when the gadget driver is already unbound.

serial: lantiq: add missing interrupt ack
commit
306320034e8fbe7ee1cc4f5269c55658b4612048 upstream.
Currently, the error interrupt is never acknowledged, so once active it
will stay active indefinitely, causing the handler to be called in an
infinite loop.

If the boot firmware has already established tunnels, especially ones
that have special requirements from the link such as DisplayPort, we
should not blindly enable CL states (nor change the TMU configuration).
Otherwise the existing tunnels may not work as expected.
For this reason, skip the CL state enabling when we go over the existing
topology. This will also keep the TMU settings untouched because we do
not change the TMU configuration when CL states are not enabled.

commit

The VBIOS image update flow requires userspace to:
1) Write the image to `psp_vbflash`
2) Read `psp_vbflash`
3) Poll `psp_vbflash_status` to check for completion
If userspace reads `psp_vbflash` before writing an image, it's
possible that it causes problems that can put the dGPU into an invalid
state.
Explicitly check that an image has been written before letting a read
succeed.

This seems to have existed for ever but is now more apparant after
commit
9bff18d13473 ("drm/ttm: use per BO cleanup workers")
My analysis: two threads are running, one in the irq signalling the
fence, in dma_fence_signal_timestamp_locked, it has done the
DMA_FENCE_FLAG_SIGNALLED_BIT setting, but hasn't yet reached the
callbacks.
The second thread in nouveau_cli_work_ready, where it sees the fence is
signalled, so then puts the fence, cleanups the object and frees the
work item, which contains the callback.
Thread one goes again and tries to call the callback and causes the
use-after-free.
Proposed fix: lock the fence signalled check in nouveau_cli_work_ready,
so either the callbacks are done or the memory is freed.

commit
722d90822321497e2837cfc9000202e256e6b32f upstream.
issue_discard() passes GFP_NOWAIT to __blkdev_issue_discard() despite
its code assuming bio_alloc() always succeeds.
Commit
3dba53a958a75 ("dm thin: use __blkdev_issue_discard for async
discard support") clearly shows where things went bad:
Before commit
3dba53a958a75, dm-thin.c's open-coded
__blkdev_issue_discard_async() properly handled using GFP_NOWAIT.
Unfortunately __blkdev_issue_discard() doesn't and it was missed
during review.

ALSA: usb-audio: Add quirk flag for HEM devices to enable native DSD playback
commit
122e2cb7e1a30438cc0e8bf70d4279db245d7d5b upstream.
This commit adds new DEVICE_FLG with QUIRK_FLAG_DSD_RAW and Vendor Id for
HEM devices which supports native DSD. Prior to this change Linux kernel
was not enabling native DSD playback for HEM devices, and as a result,
DSD audio was being converted to PCM "on the fly". HEM devices,
when connected to the system, would only play audio in PCM format,
even if the source material was in DSD format. With the addition of new
VENDOR_FLG in the quircks.c file, the devices are now correctly
recognized, and raw DSD data is transmitted to the device,
allowing for native DSD playback.

ALSA: usb-audio: Fix broken resume due to UAC3 power state
commit
8ba61c9f6c9bdfbf9d197b0282641d24ae909778 upstream.
As reported in the bugzilla below, the PM resume of a UAC3 device may
fail due to the incomplete power state change, stuck at D1. The
reason is that the driver expects the full D0 power state change only
at hw_params, while the normal PCM resume procedure doesn't call
hw_params.
For fixing the bug, we add the same power state update to D0 at the
prepare callback, which is certainly called by the resume procedure.
Note that, with this change, the power state change in the hw_params
becomes almost redundant, since snd_usb_hw_params() doesn't touch the
parameters (at least it tires so). But dropping it is still a bit
risky (e.g. we have the media-driver binding), so I leave the D0 power
state change in snd_usb_hw_params() as is for now.

btrfs: can_nocow_file_extent should pass down args->strict from callers
commit
deccae40e4b30f98837e44225194d80c8baf2233 upstream.
Commit
619104ba453ad0 ("btrfs: move common NOCOW checks against a file
extent into a helper") changed our call to btrfs_cross_ref_exist() to
always pass false for the 'strict' parameter. We're passing this down
through the stack so that we can do a full check for cross references
during swapfile activation.
With strict always false, this test fails:
btrfs subvol create swappy
chattr +C swappy
fallocate -l1G swappy/swapfile
chmod 600 swappy/swapfile
mkswap swappy/swapfile
btrfs subvol snap swappy swapsnap
btrfs subvol del -C swapsnap
btrfs fi sync /
sync;sync;sync
swapon swappy/swapfile
The fix is to just use args->strict, and everyone except swapfile
activation is passing false.

[CAUSE]
Since the introduction of global roots, we handle
csum/extent/free-space-tree roots as global roots, even if no
extent-tree-v2 feature is enabled.
So for regular csum/extent/fst roots, we load them into
fs_info::global_root_tree rb tree.
And we should not expect any conflicts in that rb tree, thus we have an
ASSERT() inside btrfs_global_root_insert().
But rescue=usebackuproot can break the assumption, as we will try to
load those trees again and again as long as we have bad roots and have
backup roots slot remaining.
So in that case we can have conflicting roots in the rb tree, and
triggering the ASSERT() crash.
[FIX]
We can safely remove that ASSERT(), as the caller will properly put the
offending root.
To make further debugging easier, also add two explicit error messages:
- Error message for conflicting global roots
- Error message when using backup roots slot

kexec: support purgatories with .text.hot sections
commit
8652d44f466ad5772e7d1756e9457046189b0dfc upstream.
Patch series "kexec: Fix kexec_file_load for llvm16 with PGO", v7.
When upreving llvm I realised that kexec stopped working on my test
platform.
The reason seems to be that due to PGO there are multiple .text sections
on the purgatory, and kexec does not supports that.
This patch (of 4):
Clang16 links the purgatory text in two sections when PGO is in use:
[ 1] .text PROGBITS

And both of them have their range [sh_addr ... sh_addr+sh_size] on the
area pointed by `e_entry`.
This causes that image->start is calculated twice, once for .text and
another time for .text.hot. The second calculation leaves image->start
in a random location.
Because of this, the system crashes immediately after:

nilfs2: reject devices with insufficient block count
commit
92c5d1b860e9581d64baca76779576c0ab0d943d upstream.
The current sanity check for nilfs2 geometry information lacks checks for
the number of segments stored in superblocks, so even for device images
that have been destructively truncated or have an unusually high number of
segments, the mount operation may succeed.
This causes out-of-bounds block I/O on file system block reads or log
writes to the segments, the latter in particular causing
"a_ops->writepages" to repeatedly fail, resulting in sync_inodes_sb() to
hang.
Fix this issue by checking the number of segments stored in the superblock
and avoiding mounting devices that can cause out-of-bounds accesses. To
eliminate the possibility of overflow when calculating the number of
blocks required for the device from the number of segments, this also adds
a helper function to calculate the upper bound on the number of segments
and inserts a check using it.

nilfs2: fix possible out-of-bounds segment allocation in resize ioctl
commit
fee5eaecca86afa544355569b831c1f90f334b85 upstream.
Syzbot reports that in its stress test for resize ioctl, the log writing
function nilfs_segctor_do_construct hits a WARN_ON in
nilfs_segctor_truncate_segments().
It turned out that there is a problem with the current implementation of
the resize ioctl, which changes the writable range on the device (the
range of allocatable segments) at the end of the resize process.
This order is necessary for file system expansion to avoid corrupting the
superblock at trailing edge. However, in the case of a file system
shrink, if log writes occur after truncating out-of-bounds trailing
segments and before the resize is complete, segments may be allocated from
the truncated space.
The userspace resize tool was fine as it limits the range of allocatable
segments before performing the resize, but it can run into this issue if
the resize ioctl is called alone.
Fix this issue by changing nilfs_sufile_resize() to update the range of
allocatable segments immediately after successful truncation of segment
space in case of file system shrink.

nilfs2: fix incomplete buffer cleanup in nilfs_btnode_abort_change_key()
commit
2f012f2baca140c488e43d27a374029c1e59098d upstream.
A syzbot fault injection test reported that nilfs_btnode_create_block, a
helper function that allocates a new node block for b-trees, causes a
kernel BUG for disk images where the file system block size is smaller
than the page size.
This was due to unexpected flags on the newly allocated buffer head, and
it turned out to be because the buffer flags were not cleared by
nilfs_btnode_abort_change_key() after an error occurred during a b-tree
update operation and the buffer was later reused in that state.
Fix this issue by using nilfs_btnode_delete() to abandon the unused
preallocated buffer in nilfs_btnode_abort_change_key().

zswap: do not shrink if cgroup may not zswap
commit
0bdf0efa180a9cb1361cbded4e2260a49306ac89 upstream.
Before storing a page, zswap first checks if the number of stored pages
exceeds the limit specified by memory.zswap.max, for each cgroup in the
hierarchy. If this limit is reached or exceeded, then zswap shrinking is
triggered and short-circuits the store attempt.
However, since the zswap's LRU is not memcg-aware, this can create the
following pathological behavior: the cgroup whose zswap limit is 0 will
evict pages from other cgroups continually, without lowering its own zswap
usage. This means the shrinking will continue until the need for swap
ceases or the pool becomes empty.
As a result of this, we observe a disproportionate amount of zswap
writeback and a perpetually small zswap pool in our experiments, even
though the pool limit is never hit.
More generally, a cgroup might unnecessarily evict pages from other
cgroups before we drive the memcg back below its limit.
This patch fixes the issue by rejecting zswap store attempt without
shrinking the pool when obj_cgroup_may_zswap() returns false.

more resources are available for other threads to run.
There exists a problem in sq thread: it does not unlock sqd->lock before
releasing CPU resources every time. This makes other threads pending on
sqd->lock for a long time. For example, the following interfaces all
require sqd->lock: io_sq_offload_create(), io_register_iowq_max_workers()

It happens because of play_dma_data/capture_dma_data pointers are NULL.
Current implementation assigns these pointers at snd_soc_dai_driver
startup() callback and reset them back to NULL at shutdown(). But
soc_pcm_open() sequence uses DMA pointers in dmaengine_pcm_open()
before snd_soc_dai_driver startup().
Most generic DMA capable I2S drivers use snd_soc_dai_driver probe()
callback to init DMA pointers only once at probe. So move DMA init
to dw_i2s_dai_probe and drop shutdown() and startup() callbacks.

ASoC: soc-pcm: test if a BE can be prepared
[ Upstream commit
e123036be377ddf628226a7c6d4f9af5efd113d3 ]
In the BE hw_params configuration, the existing code checks if any of the
existing FEs are prepared, running, paused or suspended - and skips the
configuration in those cases. This allows multiple calls of hw_params
which the ALSA state machine supports.
This check is not handled for the prepare stage, which can lead to the
same BE being prepared multiple times. This patch adds a check similar to
that of the hw_params, with the main difference being that the suspended
state is allowed: the ALSA state machine allows a transition from
suspended to prepared with hw_params skipped.
This problem was detected on Intel IPC4/SoundWire devices, where the BE
dailink .prepare stage is used to configure the SoundWire stream with a
bank switch. Multiple .prepare calls lead to conflicts with the .trigger
operation with IPC4 configurations. This problem was not detected earlier
on Intel devices, HDaudio BE dailinks detect that the link is already
prepared and skip the configuration, and for IPC3 devices there is no BE
trigger.

btrfs: scrub: try harder to mark RAID56 block groups read-only
[ Upstream commit
7561551e7ba870b9659083b95feb520fb2dacce3 ]
Currently we allow a block group not to be marked read-only for scrub.
But for RAID56 block groups if we require the block group to be
read-only, then we're allowed to use cached content from scrub stripe to
reduce unnecessary RAID56 reads.
So this patch would:
- Make btrfs_inc_block_group_ro() try harder
During my tests, for cases like btrfs/061 and btrfs/064, we can hit
ENOSPC from btrfs_inc_block_group_ro() calls during scrub.
The reason is if we only have one single data chunk, and trying to
scrub it, we won't have any space left for any newer data writes.
But this check should be done by the caller, especially for scrub
cases we only temporarily mark the chunk read-only.
And newer data writes would always try to allocate a new data chunk
when needed.
- Return error for scrub if we failed to mark a RAID56 chunk read-only

power: supply: Fix logic checking if system is running from battery
[ Upstream commit
95339f40a8b652b5b1773def31e63fc53c26378a ]
The logic used for power_supply_is_system_supplied() counts all power
supplies and assumes that the system is running from AC if there is
either a non-battery power-supply reporting to be online or if no
power-supplies exist at all.
The second rule is for desktop systems, that don't have any
battery/charger devices. These systems will incorrectly report to be
powered from battery once a device scope power-supply is registered
(e.g. a HID device), since these power-supplies increase the counter.
Apart from HID devices, recent dGPUs provide UCSI power supplies on a
desktop systems. The dGPU by default doesn't have anything plugged in so
it's 'offline'. This makes power_supply_is_system_supplied() return 0
with a count of 1 meaning all drivers that use this get a wrong judgement.
To fix this case adjust the logic to also examine the scope of the power
supply. If the power supply is deemed a device power supply, then don't
count it.

irqchip/gic-v3: Disable pseudo NMIs on Mediatek devices w/ firmware issues
[ Upstream commit
44bd78dd2b8897f59b7e3963f088caadb7e4f047 ]
Some Chromebooks with Mediatek SoCs have a problem where the firmware
doesn't properly save/restore certain GICR registers. Newer
Chromebooks should fix this issue and we may be able to do firmware
updates for old Chromebooks. At the moment, the only known issue with
these Chromebooks is that we can't enable "pseudo NMIs" since the
priority register can be lost. Enabling "pseudo NMIs" on Chromebooks
with the problematic firmware causes crashes and freezes.
Let's detect devices with this problem and then disable "pseudo NMIs"
on them. We'll detect the problem by looking for the presence of the
"mediatek,broken-save-restore-fw" property in the GIC device tree
node. Any devices with fixed firmware will not have this property.
Our detection plan works because we never bake a Chromebook's device
tree into firmware. Instead, device trees are always bundled with the
kernel. We'll update the device trees of all affected Chromebooks and
then we'll never enable "pseudo NMI" on a kernel that is bundled with
old device trees. When a firmware update is shipped that fixes this
issue it will know to patch the device tree to remove the property.
In order to make this work, the quick detection mechanism of the GICv3
code is extended to be able to look for properties in addition to
looking at "compatible".

This does in fact make systemd journald choke, since during boot the
