HAVE_ARCH_HUGE_VMAP also works on XIP kernel, so remove its dependency on
!XIP_KERNEL.
This also fixes a boot problem for XIP kernel introduced by the commit in

Top of the kernel thread stack should be reserved for pt_regs. However
this is not the case for the idle threads of the secondary boot harts.
Their stacks overlap with their pt_regs, so both may get corrupted.
Similar issue has been fixed for the primary hart, see c7cdd96eca
("riscv: prevent stack corruption by reserving task_pt_regs(p) early").
However that fix was not propagated to the secondary harts. The problem
has been noticed in some CPU hotplug tests with V enabled. The function
smp_callin stored several registers on stack, corrupting top of pt_regs
structure including status field. As a result, kernel attempted to save
or restore inexistent V context.

ERETAx can fail in multiple ways:
(1) ELR_EL2 points lalaland
(2) we get a PAC failure
(3) SPSR_EL2 has the wrong mode
(1) is easy, as we just let the CPU do its thing and deliver an
Instruction Abort. However, (2) and (3) are interesting, because
the PAC failure priority is way below that of the Illegal Execution
State exception.
Which means that if we have detected a PAC failure (and that we have
FPACCOMBINE), we must be careful to give priority to the Illegal
Execution State exception, should one be pending.
Solving this involves hoisting the SPSR calculation earlier and
testing for the IL bit before injecting the FPAC exception.
In the extreme case of a ERETAx returning to an invalid mode *and*
failing its PAC check, we end up with an Instruction Abort (due
to the new PC being mangled by the failed Auth) *and* PSTATE.IL
being set. Which matches the requirements of the architecture.
Whilst we're at it, remove a stale comment that states the obvious
and only confuses the reader.

tl;dr: CPUs with CPUID.80000008H but without CPUID.01H:EDX[CLFSH]
will end up reporting cache_line_size()==0 and bad things happen.
Fill in a default on those to avoid the problem.
Long Story:
The kernel dies a horrible death if c->x86_cache_alignment (aka.
cache_line_size() is 0. Normally, this value is populated from
c->x86_clflush_size.
Right now the code is set up to get c->x86_clflush_size from two
places. First, modern CPUs get it from CPUID. Old CPUs that don't
have leaf 0x80000008 (or CPUID at all) just get some sane defaults
from the kernel in get_cpu_address_sizes().
The vast majority of CPUs that have leaf 0x80000008 also get
->x86_clflush_size from CPUID. But there are oddballs.
Intel Quark CPUs[1] and others[2] have leaf 0x80000008 but don't set
CPUID.01H:EDX[CLFSH], so they skip over filling in ->x86_clflush_size:
cpuid(0x00000001, &tfms, &misc, &junk, &cap0);
if (cap0 & (1<<19))
c->x86_clflush_size = ((misc >> 8) & 0xff) * 8;
So they: land in get_cpu_address_sizes() and see that CPUID has level
0x80000008 and jump into the side of the if() that does not fill in
c->x86_clflush_size. That assigns a 0 to c->x86_cache_alignment, and
hilarity ensues in code like:
buffer = kzalloc(ALIGN(sizeof(*buffer), cache_line_size()),
GFP_KERNEL);
To fix this, always provide a sane value for ->x86_clflush_size.
Big thanks to Andy Shevchenko for finding and reporting this and also
providing a first pass at a fix. But his fix was only partial and only
worked on the Quark CPUs. It would not, for instance, have worked on
the QEMU config.
1. https://raw.githubusercontent.com/InstLatx64/InstLatx64/master/GenuineIntel/GenuineIntel0000590_Clanton_03_CPUID.txt
2. You can also get this behavior if you use "-cpu 486,+clzero"
in QEMU.

kmemleak shows that there is a memory leak in io_uring read operation,
where a buffer is allocated at iovec import, but never de-allocated.
The memory is allocated at io_async_rw->free_iovec, but, then
io_async_rw is kfreed, taking the allocated memory with it. I saw this
happening when the read operation fails with -11 (EAGAIN).
This is the kmemleak splat.

This occurs because the async data cleanup functions are not set for
read/write operations. As a result, the potentially allocated iovec in
the rw async data is not freed before the async data is released,
leading to a memory leak.
With this following patch, kmemleak does not show the leaked memory
anymore, and all liburing tests pass.

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
The existing logic to pick a DMIC blob is based on several historical
assumptions that the NHLT in BIOS always contains 32-bits per sample
type (first patch, [1]).
The other issue with the existing logic is that it was designed to care only
about the bit depth of the format and fails to find the existing and correct
blob when rate/channels are different on the FE side compared to what we should
be using on the DAI side (we have components in path which can change
rate/channel count).
These issues have not been observed in past but with new MTL based (Windows)
laptops and new topologies to enhance the audio quality, we started to see weird
issues around how our assumptions of vendors failed.
Since some NHLT blob handling cleanup has been done for 6.10, this series will
complete that work to cover even cases that we don't anticipate to see.

The 'ld' instruction requires a 4-byte aligned displacement because it
is a DS-form instruction. But the "m" asm constraint doesn't enforce
that.
Add a special case of __get_user_asm2_goto() so that the "YZ" constraint
can be used for "ld".
The "Z" constraint is documented in the GCC manual PowerPC machine
constraints, and specifies a "memory operand accessed with indexed or
indirect addressing". "Y" is not documented in the manual but specifies
a "memory operand for a DS-form instruction". Using both allows the
compiler to generate a DS-form "ld" or X-form "ldx" as appropriate.
The change has to be conditional on CONFIG_PPC_KERNEL_PREFIXED because
the "Y" constraint does not guarantee 4-byte alignment when prefixed
instructions are enabled.
No build errors have been reported due to this, but the possibility is
there depending on compiler code generation decisions.

The 'std' instruction requires a 4-byte aligned displacement because
it is a DS-form instruction, and as the assembler says, 18 is not a
multiple of 4.
A similar error is seen with GCC 13 and CONFIG_UBSAN_SIGNED_WRAP=y.
The fix is to change the constraint on the memory operand to put_user(),
from "m" which is a general memory reference to "YZ".
The "Z" constraint is documented in the GCC manual PowerPC machine
constraints, and specifies a "memory operand accessed with indexed or
indirect addressing". "Y" is not documented in the manual but specifies
a "memory operand for a DS-form instruction". Using both allows the
compiler to generate a DS-form "std" or X-form "stdx" as appropriate.
The change has to be conditional on CONFIG_PPC_KERNEL_PREFIXED because
the "Y" constraint does not guarantee 4-byte alignment when prefixed
instructions are enabled.
Unfortunately clang doesn't support the "Y" constraint so that has to be
behind an ifdef.
Although the build error is only seen with GCC 13/14, that appears
to just be luck. The constraint has been incorrect since it was first
added.

Currently we only check the bit depth value among to DAI formats, but other
parameters might be constant, like number of channels and/or rate.
In capture we use the fe params as a reference to find the format and blob
which should be used, but in the path we can have components which can
handle expanding/narrowing number of channels or do a resample.
In these cases the topology is expected to have 'fixed' parameter for
channels/rates/bit depth and the conversion to the fe format is going to
be done within the path.
In practice this patch fixes issues like:
All DMIC formats are fixed four channels
We have a component which converts the four channel to stereo
FE is opened with 2 channel
Even if we have the correct bit depth format and blob (for four channel) we
will still be looking for stereo configurations, which will fail.
Note: the adjustment of params have switched order with the checking of
single bit depth (needed for the NHLT blob fallback support). This change
is non function, just that if the sof_ipc4_narrow_params_to_format() would
fail, there is no point of checking the single bit depth.

sof_ipc4_copier_is_single_bitdepth() to clear the confusion of the use of
'format' when we are querying information on the bit depth.
Format is used to describe a combination of parameters (rate, channels,

The ACPI NHLT table always had 32-bit DMIC blob even if 16-bit was also
present and taken as a 'rule' which obviously got broken and there is at
least one device on the market which ships with only 16-bit DMIC
configuration blob.
This corner case has never been supported and it is going to need topology
updates for DMIC copier to support multiple formats.
As for the kernel side: if the copier supports multiple formats and the
preferred 32-bit DMIC blob is not found then we will try to get a 16-bit
DMIC configuration and look for a 16-bit copier config.

Recent commit 0cfe71f45f ("netdev: add queue stats") added
a lot of useful stats, but only those immediately needed by virtio.
Presumably virtio does not support CHECKSUM_COMPLETE,
so statistic for that form of checksumming wasn't included.
Other drivers will definitely need it, in fact we expect it
to be needed in net-next soon (mlx5). So let's add the definition
of the counter for CHECKSUM_COMPLETE to uAPI in net already,
so that the counters are in a more natural order (all subsequent
counters have not been present in any released kernel, yet).

Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
Patch #1 syzbot reports that nf_reinject() could be called without
rcu_read_lock() when flushing pending packets at nfnetlink
queue removal, from Eric Dumazet.
Patch #2 flushes ipset list:set when canceling garbage collection to
reference to other lists to fix a race, from Jozsef Kadlecsik.
Patch #3 restores q-in-q matching with nft_payload by reverting
f6ae9f120d ("netfilter: nft_payload: add C-VLAN support").
Patch #4 fixes vlan mangling in skbuff when vlan offload is present
in skbuff, without this patch nft_payload corrupts packets
in this case.
Patch #5 fixes possible nul-deref in tproxy no IP address is found in
netdevice, reported by syzbot and patch from Florian Westphal.
Patch #6 removes a superfluous restriction which prevents loose fib
lookups from input and forward hooks, from Eric Garver.
My assessment is that patches #1, #2 and #5 address possible kernel
crash, anything else in this batch fixes broken features.

The driver overrides the NUMA node id of the device regardless of
whether it knows its correct value (often setting it to -1 even though
the node id is advertised in 'struct device'). This can lead to
suboptimal configurations.
This patch fixes this behavior and makes the shared memory allocation
functions use the NUMA node id advertised by the underlying device.

Intel Wired LAN Driver Updates 2024-05-28 (e1000e, i40e, ice) [part]
This series includes a variety of fixes that have been accumulating on the
Intel Wired LAN dev-queue.
Hui Wang provides a fix for suspend/resume on e1000e due to failure
to correctly setup the SMBUS in enable_ulp().
Thinh Tran provides a fix for EEH I/O suspend/resume on i40e to
ensure that I/O operations can continue after a resume. To avoid duplicate
code, the common logic is factored out of i40e_suspend and i40e_resume.
Paul Greenwalt provides a fix to correctly map the 200G PHY types to link
speeds in the ice driver.
Dave Ertman provides a fix correcting devlink parameter unregistration in
the event that the driver loads in safe mode and some of the parameters
were not registered.

On module load, the ice driver checks for the lack of a specific PF
capability to determine if it should reduce the number of devlink params
to register. One situation when this test returns true is when the
driver loads in safe mode. The same check is not present on the unload
path when devlink params are unregistered. This results in the driver
triggering a WARN_ON in the kernel devlink code.
The current check and code path uses a reduction in the number of elements
reported in the list of params. This is fragile and not good for future
maintaining.
Change the parameters to be held in two lists, one always registered and
one dependent on the check.
Add a symmetrical check in the unload path so that the correct parameters
are unregistered as well.

When EEH events occurs, the callback functions in the i40e, which are
managed by the EEH driver, will completely suspend and resume all IO
operations.
- In the PCI error detected callback, replaced i40e_prep_for_reset()
with i40e_io_suspend(). The change is to fully suspend all I/O
operations
- In the PCI error slot reset callback, replaced pci_enable_device_mem()
with pci_enable_device(). This change enables both I/O and memory of
the device.
- In the PCI error resume callback, replaced i40e_handle_reset_warning()
with i40e_io_resume(). This change allows the system to resume I/O
operations

Two new functions, i40e_io_suspend() and i40e_io_resume(), have been
introduced. These functions were factored out from the existing
i40e_suspend() and i40e_resume() respectively. This factoring was
done due to concerns about the logic of the I40E_SUSPENSED state, which
caused the device to be unable to recover. The functions are now used
in the EEH handling for device suspend/resume callbacks.
The function i40e_enable_mc_magic_wake() has been moved ahead of
i40e_io_suspend() to ensure it is declared before being used.

The commit 861e808602 ("e1000e: move force SMBUS from enable ulp
function to avoid PHY loss issue") introduces a regression on
PCH_MTP_I219_LM18 (PCIID: 0x8086550A). Without the referred commit, the
ethernet works well after suspend and resume, but after applying the
commit, the ethernet couldn't work anymore after the resume and the
dmesg shows that the NIC link changes to 10Mbps (1000Mbps originally):
[ 43.305084] e1000e 0000:00:1f.6 enp0s31f6: NIC Link is Up 10 Mbps Full Duplex, Flow Control: Rx/Tx
Without the commit, the force SMBUS code will not be executed if
"return 0" or "goto out" is executed in the enable_ulp(), and in my
case, the "goto out" is executed since FWSM_FW_VALID is set. But after
applying the commit, the force SMBUS code will be ran unconditionally.
Here move the force SMBUS code back to enable_ulp() and put it
immediately ahead of hw->phy.ops.release(hw), this could allow the
longest settling time as possible for interface in this function and
doesn't change the original code logic.
The issue was found on a Lenovo laptop with the ethernet hw as below:
00:1f.6 Ethernet controller [0200]: Intel Corporation Device [8086:550a]
(rev 20).
And this patch is verified (cable plug and unplug, system suspend
and resume) on Lenovo laptops with ethernet hw: [8086:550a],
[8086:550b], [8086:15bb], [8086:15be], [8086:1a1f], [8086:1a1c] and

__dst_negative_advice() does not enforce proper RCU rules when
sk->dst_cache must be cleared, leading to possible UAF.
RCU rules are that we must first clear sk->sk_dst_cache,
then call dst_release(old_dst).
Note that sk_dst_reset(sk) is implementing this protocol correctly,
while __dst_negative_advice() uses the wrong order.
Given that ip6_negative_advice() has special logic
against RTF_CACHE, this means each of the three ->negative_advice()
existing methods must perform the sk_dst_reset() themselves.
Note the check against NULL dst is centralized in
__dst_negative_advice(), there is no need to duplicate
it in various callbacks.
