drm/amdgpu: fix amdgpu_irq_put call trace in gmc_v11_0_hw_fini
The gmc.ecc_irq is enabled by firmware per IFWI setting,
and the host driver is not privileged to enable/disable
the interrupt. So, it is meaningless to use the amdgpu_irq_put
function in gmc_v11_0_hw_fini, which also leads to the call

drm/amdgpu: Enable doorbell selfring after resize FB BAR
[Why]
The selfring doorbell aperture will change when resize FB
BAR successfully during gmc sw init, we should reorder
the sequence of enabling doorbell selfring aperture.
[How]
Move enable_doorbell_selfring_aperture from *_common_hw_init
to *_common_late_init.
This fixes the potential issue that GPU ring its own

ASoC: codecs: wcd938x: fix accessing regmap on unattached devices
The WCD938x comes with three devices on two Linux drivers:
1. RX Soundwire device (wcd938x-sdw.c driver),
2. TX Soundwire device, which is used to access devices via regmap (also
wcd938x-sdw.c driver),
3. platform device (wcd938x.c driver) - glue and component master,
actually having most of the code using TX Soundwire device regmap.
When RX and TX Soundwire devices probe, the component master (platform
device) bind tries to write micbias configuration via TX Soundwire
regmap. This might happen before TX Soundwire enumerates, so the regmap
access fails. On Qualcomm SM8550 board with WCD9385:
qcom-soundwire 6d30000.soundwire-controller: Qualcomm Soundwire controller v2.0.0 Registered
wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:4 (ops wcd938x_sdw_component_ops)
wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:3 (ops wcd938x_sdw_component_ops)
qcom-soundwire 6ad0000.soundwire-controller: swrm_wait_for_wr_fifo_avail err write overflow
Fix the issue by:
1. Moving the regmap creation from platform device to TX Soundwire
device. The regmap settings are moved as-is with one difference:
making the wcd938x_regmap_config const.
2. Using regmap in cache only mode till the actual TX Soundwire device
enumerates and then sync the regmap cache.

x86-64: mm: clarify the 'positive addresses' user address rules
Dave Hansen found the "(long) addr >= 0" code in the x86-64 access_ok
checks somewhat confusing, and suggested using a helper to clarify what
the code is doing.
So this does exactly that: clarifying what the sign bit check is all
about, by adding a helper macro that makes it clear what it is testing.
This also adds some explicit comments talking about how even with LAM
enabled, any addresses with the sign bit will still GP-fault in the
non-canonical region just above the sign bit.
This is all what allows us to do the user address checks with just the
sign bit, and furthermore be a bit cavalier about accesses that might be
done with an additional offset even past that point.
(And yes, this talks about 'positive' even though zero is also a valid
user address and so technically we should call them 'non-negative'. But
I don't think using 'non-negative' ends up being more understandable).

x86: mm: remove 'sign' games from LAM untagged_addr*() macros
The intent of the sign games was to not modify kernel addresses when
untagging them. However, that had two issues:
(a) it didn't actually work as intended, since the mask was calculated
as 'addr >> 63' on an _unsigned_ address. So instead of getting a
mask of all ones for kernel addresses, you just got '1'.
(b) untagging a kernel address isn't actually a valid operation anyway.
Now, (a) had originally been true for both 'untagged_addr()' and the
remote version of it, but had accidentally been fixed for the regular
version of untagged_addr() by commit
e0bddc19ba95 ("x86/mm: Reduce
untagged_addr() overhead for systems without LAM"). That one rewrote
the shift to be part of the alternative asm code, and in the process
changed the unsigned shift into a signed 'sar' instruction.
And while it is true that we don't want to turn what looks like a kernel
address into a user address by masking off the high bit, that doesn't
need these sign masking games - all it needs is that the mm context
'untag_mask' value has the high bit set.
Which it always does.
So simplify the code by just removing the superfluous (and in the case
of untagged_addr_remote(), still buggy) sign bit games in the address
masking.

x86: mm: remove architecture-specific 'access_ok()' define
There's already a generic definition of 'access_ok()' in the
asm-generic/access_ok.h header file, and the only difference bwteen that
and the x86-specific one is the added check for WARN_ON_IN_IRQ().
And it turns out that the reason for that check is long gone: it used to
use a "user_addr_max()" inline function that depended on the current
thread, and caused problems in non-thread contexts.
For details, see commits
7c4788950ba5 ("x86/uaccess, sched/preempt:
Verify access_ok() context") and in particular commit
ae31fe51a3cc
("perf/x86: Restore TASK_SIZE check on frame pointer") about how and why
this came to be.
But that "current task" issue was removed in the big set_fs() removal by
Christoph Hellwig in commit
47058bb54b57 ("x86: remove address space
overrides using set_fs()").
So the reason for the test and the architecture-specific access_ok()
define no longer exists, and is actually harmful these days. For
example, it led various 'copy_from_user_nmi()' games (eg using
__range_not_ok() instead, and then later converted to __access_ok() when
that became ok).
And that in turn meant that LAM was broken for the frame following
before this series, because __access_ok() used to not do the address
untagging.
Accessing user state still needs care in many contexts, but access_ok()
is not the place for this test.

x86-64: make access_ok() independent of LAM
The linear address masking (LAM) code made access_ok() more complicated,
in that it now needs to untag the address in order to verify the access
range. See commit
74c228d20a51 ("x86/uaccess: Provide untagged_addr()
and remove tags before address check").
We were able to avoid that overhead in the get_user/put_user code paths
by simply using the sign bit for the address check, and depending on the
GP fault if the address was non-canonical, which made it all independent
of LAM.
And we can do the same thing for access_ok(): simply check that the user
pointer range has the high bit clear. No need to bother with any
address bit masking.
In fact, we can go a bit further, and just check the starting address
for known small accesses ranges: any accesses that overflow will still
be in the non-canonical area and will still GP fault.
To still make syzkaller catch any potentially unchecked user addresses,
we'll continue to warn about GP faults that are caused by accesses in
the non-canonical range. But we'll limit that to purely "high bit set
and past the one-page 'slop' area".
We could probably just do that "check only starting address" for any
arbitrary range size: realistically all kernel accesses to user space
will be done starting at the low address. But let's leave that kind of
optimization for later. As it is, this already allows us to generate
simpler code and not worry about any tag bits in the address.
The one thing to look out for is the GUP address check: instead of
actually copying data in the virtual address range (and thus bad
addresses being caught by the GP fault), GUP will look up the page
tables manually. As a result, the page table limits need to be checked,
and that was previously implicitly done by the access_ok().
With the relaxed access_ok() check, we need to just do an explicit check
for TASK_SIZE_MAX in the GUP code instead. The GUP code already needs
to do the tag bit unmasking anyway, so there this is all very
straightforward, and there are no LAM issues.

igc: read before write to SRRCTL register
igc_configure_rx_ring() function will be called as part of XDP program

this timestamp enablement will be overwritten when buffer size is
written into SRRCTL register.
Thus, this commit read the register value before write to SRRCTL

tool. The tool enables Rx hardware timestamp and then attach XDP program
to igc driver. It will display hardware timestamp of UDP packet with

ethtool: Fix uninitialized number of lanes
It is not possible to set the number of lanes when setting link modes
using the legacy IOCTL ethtool interface. Since 'struct
ethtool_link_ksettings' is not initialized in this path, drivers receive
an uninitialized number of lanes in 'struct
ethtool_link_ksettings::lanes'.
When this information is later queried from drivers, it results in the
ethtool code making decisions based on uninitialized memory, leading to
the following KMSAN splat [1]. In practice, this most likely only
happens with the tun driver that simply returns whatever it got in the
set operation.
As far as I can tell, this uninitialized memory is not leaked to user
space thanks to the 'ethtool_ops->cap_link_lanes_supported' check in
linkmodes_prepare_data().
Fix by initializing the structure in the IOCTL path. Did not find any
more call sites that pass an uninitialized structure when calling
'ethtool_ops::set_link_ksettings()'.

In a few scenarios, firmware returns an invalid lmac_type_id, which
is resulting in below kernel panic. This patch adds the missing
validation of the lmac_type_id field.

octeontx2-af: Secure APR table update with the lock
APR table contains the lmtst base address of PF/VFs. These entries
are updated by the PF/VF during the device probe. The lmtst address
is fetched from HW using "TXN_REQ" and "ADDR_RSP_STS" registers.
The lock tries to protect these registers from getting overwritten
when multiple PFs invokes rvu_get_lmtaddr() simultaneously.
For example, if PF1 submit the request and got permitted before it
reads the response and PF2 got scheduled submit the request then the
response of PF1 is overwritten by the PF2 response.
