mm/shuffle: fix section mismatch warning
clang sometimes decides not to inline shuffle_zone(), but it calls a
__meminit function. Without the extra __meminit annotation we get this
warning:
WARNING: modpost: vmlinux.o(.text+0x2a86d4): Section mismatch in reference from the function shuffle_zone() to the function .meminit.text:__shuffle_zone()
The function shuffle_zone() references
the function __meminit __shuffle_zone().
This is often because shuffle_zone lacks a __meminit
annotation or the annotation of __shuffle_zone is wrong.
shuffle_free_memory() did not show the same problem in my tests, but it
could happen in theory as well, so mark both as __meminit.

"During the merge window an issue with si_perf and the siginfo ABI came
up. The alpha and sparc siginfo structure layout had changed with the
addition of SIGTRAP TRAP_PERF and the new field si_perf.
The reason only alpha and sparc were affected is that they are the
only architectures that use si_trapno.
Looking deeper it was discovered that si_trapno is used for only a few
select signals on alpha and sparc, and that none of the other
_sigfault fields past si_addr are used at all. Which means technically
no regression on alpha and sparc.
While the alignment concerns might be dismissed the abuse of si_errno
by SIGTRAP TRAP_PERF does have the potential to cause regressions in
existing userspace.
While we still have time before userspace starts using and depending
on the new definition siginfo for SIGTRAP TRAP_PERF this set of
changes cleans up siginfo_t.
- The si_trapno field is demoted from magic alpha and sparc status
and made an ordinary union member of the _sigfault member of
siginfo_t. Without moving it of course.
- si_perf is replaced with si_perf_data and si_perf_type ending the
abuse of si_errno.

xen-pciback: reconfigure also from backend watch handler
When multiple PCI devices get assigned to a guest right at boot, libxl
incrementally populates the backend tree. The writes for the first of
the devices trigger the backend watch. In turn xen_pcibk_setup_backend()
will set the XenBus state to Initialised, at which point no further
reconfigures would happen unless a device got hotplugged. Arrange for
reconfigure to also get triggered from the backend watch handler.

xen-pciback: redo VF placement in the virtual topology
The commit referenced below was incomplete: It merely affected what
would get written to the vdev-<N> xenstore node. The guest would still
find the function at the original function number as long as
__xen_pcibk_get_pci_dev() wouldn't be in sync. The same goes for AER wrt
__xen_pcibk_get_pcifront_dev().
Undo overriding the function to zero and instead make sure that VFs at
function zero remain alone in their slot. This has the added benefit of
improving overall capacity, considering that there's only a total of 32
slots available right now (PCI segment and bus can both only ever be
zero at present).

If a realtime allocation fails because we can't find a sufficiently

This was originally discovered by running generic/186 with the realtime

btrfs: zoned: fix parallel compressed writes
When multiple processes write data to the same block group on a
compressed zoned filesystem, the underlying device could report I/O
errors and data corruption is possible.
This happens because on a zoned file system, compressed data writes
where sent to the device via a REQ_OP_WRITE instead of a
REQ_OP_ZONE_APPEND operation. But with REQ_OP_WRITE and parallel
submission it cannot be guaranteed that the data is always submitted
aligned to the underlying zone's write pointer.
The change to using REQ_OP_ZONE_APPEND instead of REQ_OP_WRITE on a
zoned filesystem is non intrusive on a regular file system or when
submitting to a conventional zone on a zoned filesystem, as it is
guarded by btrfs_use_zone_append.

ALSA: line6: Fix racy initialization of LINE6 MIDI
The initialization of MIDI devices that are found on some LINE6
drivers are currently done in a racy way; namely, the MIDI buffer
instance is allocated and initialized in each private_init callback
while the communication with the interface is already started via
line6_init_cap_control() call before that point. This may lead to
Oops in line6_data_received() when a spurious event is received, as
reported by syzkaller.
This patch moves the MIDI initialization to line6_init_cap_control()

race. Also this reduces slightly more lines, so it's a win-win

platform/x86: intel_int0002_vgpio: Only call enable_irq_wake() when using s2idle
Commit
871f1f2bcb01 ("platform/x86: intel_int0002_vgpio: Only implement
irq_set_wake on Bay Trail") stopped passing irq_set_wake requests on to
the parents IRQ because this was breaking suspend (causing immediate
wakeups) on an Asus E202SA.
This workaround for the Asus E202SA is causing wakeup by USB keyboard to
not work on other devices with Airmont CPU cores such as the Medion Akoya
E1239T. In hindsight the problem with the Asus E202SA has nothing to do
with Silvermont vs Airmont CPU cores, so the differentiation between the
2 types of CPU cores introduced by the previous fix is wrong.
The real issue at hand is s2idle vs S3 suspend where the suspend is
mostly handled by firmware. The parent IRQ for the INT0002 device is shared
with the ACPI SCI and the real problem is that the INT0002 code should not
be messing with the wakeup settings of that IRQ when suspend/resume is
being handled by the firmware.
Note that on systems which support both s2idle and S3 suspend, which
suspend method to use can be changed at runtime.
This patch fixes both the Asus E202SA spurious wakeups issue as well as
the wakeup by USB keyboard not working on the Medion Akoya E1239T issue.
These are both fixed by replacing the old workaround with delaying the
enable_irq_wake(parent_irq) call till system-suspend time and protecting
it with a !pm_suspend_via_firmware() check so that we still do not call
it on devices using firmware-based (S3) suspend such as the Asus E202SA.
Note rather then adding #ifdef CONFIG_PM_SLEEP, this commit simply adds
a "depends on PM_SLEEP" to the Kconfig since this drivers whole purpose
is to deal with wakeup events, so using it without CONFIG_PM_SLEEP makes
no sense.

drm/i915/gem: Pin the L-shape quirked object as unshrinkable
When instantiating a tiled object on an L-shaped memory machine, we mark
the object as unshrinkable to prevent the shrinker from trying to swap
out the pages. We have to do this as we do not know the swizzling on the
individual pages, and so the data will be scrambled across swap out/in.
Not only do we need to move the object off the shrinker list, we need to
mark the object with shrink_pin so that the counter is consistent across
calls to madvise.
v2: in the madvise ioctl we need to check if the object is currently
shrinkable/purgeable, not if the object type supports shrinking

nvme-fc: clear q_live at beginning of association teardown
The __nvmf_check_ready() routine used to bounce all filesystem io if the
controller state isn't LIVE. However, a later patch changed the logic so
that it rejection ends up being based on the Q live check. The FC
transport has a slightly different sequence from rdma and tcp for
shutting down queues/marking them non-live. FC marks its queue non-live
after aborting all ios and waiting for their termination, leaving a
rather large window for filesystem io to continue to hit the transport.
Unfortunately this resulted in filesystem I/O or applications seeing I/O
errors.
Change the FC transport to mark the queues non-live at the first sign of
teardown for the association (when I/O is initially terminated).

A possible race condition exists where the request to send data is

nvme-tcp: fix possible use-after-completion
Commit
db5ad6b7f8cd ("nvme-tcp: try to send request in queue_rq
context") added a second context that may perform a network send.
This means that now RX and TX are not serialized in nvme_tcp_io_work
and can run concurrently.
While there is correct mutual exclusion in the TX path (where
the send_mutex protect the queue socket send activity) RX activity,
and more specifically request completion may run concurrently.
This means we must guarantee that any mutation of the request state
related to its lifetime, bytes sent must not be accessed when a completion
may have possibly arrived back (and processed).
The race may trigger when a request completion arrives, processed
_and_ reused as a fresh new request, exactly in the (relatively short)
window between the last data payload sent and before the request iov_iter
is advanced.
Consider the following race:
1. 16K write request is queued
2. The nvme command and the data is sent to the controller (in-capsule
or solicited by r2t)
3. After the last payload is sent but before the req.iter is advanced,
the controller sends back a completion.
4. The completion is processed, the request is completed, and reused
to transfer a new request (write or read)
5. The new request is queued, and the driver reset the request parameters
(nvme_tcp_setup_cmd_pdu).
6. Now context in (2) resumes execution and advances the req.iter
==> use-after-completion as this is already a new request.
Fix this by making sure the request is not advanced after the last
data payload send, knowing that a completion may have arrived already.
An alternative solution would have been to delay the request completion
or state change waiting for reference counting on the TX path, but besides
adding atomic operations to the hot-path, it may present challenges in
multi-stage R2T scenarios where a r2t handler needs to be deferred to
an async execution.

siginfo: Move si_trapno inside the union inside _si_fault
It turns out that linux uses si_trapno very sparingly, and as such it
can be considered extra information for a very narrow selection of
signals, rather than information that is present with every fault
reported in siginfo.
As such move si_trapno inside the union inside of _si_fault. This
results in no change in placement, and makes it eaiser
to extend _si_fault in the future as this reduces the number of
special cases. In particular with si_trapno included in the union it
is no longer a concern that the union must be pointer aligned on most
architectures because the union follows immediately after si_addr
which is a pointer.
This change results in a difference in siginfo field placement on
sparc and alpha for the fields si_addr_lsb, si_lower, si_upper,
si_pkey, and si_perf. These architectures do not implement the
signals that would use si_addr_lsb, si_lower, si_upper, si_pkey, and
si_perf. Further these architecture have not yet implemented the
userspace that would use si_perf.
The point of this change is in fact to correct these placement issues
before sparc or alpha grow userspace that cares. This change was
discussed[1] and the agreement is that this change is currently safe.

channel of data block in CIP payload. Current hard-coded stream format
is wrong.

ALSA: dice: disable double_pcm_frames mode for M-Audio Profire 610, 2626 and Avid M-Box 3 Pro
ALSA dice driver detects jumbo payload at high sampling transfer frequency
for below models:
* Avid M-Box 3 Pro
* M-Audio Profire 610
* M-Audio Profire 2626
Although many DICE-based devices have a quirk at high sampling transfer
frequency to multiplex double number of PCM frames into data block than
the number in IEC 61883-1/6, the above devices are just compliant to
IEC 61883-1/6.
This commit disables the mode of double_pcm_frames for the models.

dt-bindings: More removals of type references on common properties
Users of common properties shouldn't have a type definition as the
common schemas already have one. A few new ones slipped in and
*-names was missed in the last clean-up pass. Drop all the unnecessary
type references in the tree.
A meta-schema update to catch these is pending.

dt-bindings: media: renesas,drif: Use graph schema
Convert the renesas,drif binding schema to use the graph schema. The
binding referred to video-interfaces.txt, but it doesn't actually use any
properties from it as 'sync-active' is a custom property. As 'sync-active'
is custom, it needs a type definition.
