Pull more s390 updates from Heiko Carstens:
- A couple of virtual vs physical address confusion fixes
- Rework locking in dcssblk driver to address a lockdep warning
- Remove support for "noexec" kernel command line option since there is
no use case where it would make sense
- Simplify kernel mapping setup and get rid of quite a bit of code
- Add architecture specific __set_memory_yy() functions which allow us
to modify kernel mappings. Unlike the set_memory_xx() variants they
take void pointer start and end parameters, which allows using them
without the usual casts, and also to use them on areas larger than
8TB.
Note that the set_memory_xx() family comes with an int num_pages
parameter which overflows with 8TB. This could be addressed by
changing the num_pages parameter to unsigned long, however requires
to change all architectures, since the module code expects an int
parameter (see module_set_memory()).
This was indeed an issue since for debug_pagealloc() we call
set_memory_4k() on the whole identity mapping. Therefore address this
for now with the __set_memory_yy() variant, and address common code
later
- Use dev_set_name() and also fix memory leak in zcrypt driver error
handling
- Remove unused lsi_mask from airq_struct
- Add warning for invalid kernel mapping requests

Recently we moved most cleanup from ntfs_put_super() into
ntfs3_kill_sb() as part of a bigger cleanup. This accidently also moved
dropping inode references stashed in ntfs3's sb->s_fs_info from
@sb->put_super() to @sb->kill_sb(). But generic_shutdown_super()
verifies that there are no busy inodes past sb->put_super(). Fix this
and disentangle dropping inode references from freeing @sb->s_fs_info.

Mateusz reports that glibc turns 'fstat()' calls into 'fstatat()', and
that seems to have been going on for quite a long time due to glibc
having tried to simplify its stat logic into just one point.
This turns out to cause completely unnecessary overhead, where we then
go off and allocate the kernel side pathname, and actually look up the
empty path. Sure, our path lookup is quite optimized, but it still
causes a fair bit of allocation overhead and a couple of completely
unnecessary rounds of lockref accesses etc.
This is all hopefully getting fixed in user space, and there is a patch
floating around for just having glibc use the native fstat() system
call. But even with the current situation we can at least improve on
things by catching the situation and short-circuiting it.
Note that this is still measurably slower than just a plain 'fstat()',
since just checking that the filename is actually empty is somewhat
expensive due to inevitable user space access overhead from the kernel
(ie verifying pointers, and SMAP on x86). But it's still quite a bit
faster than actually looking up the path for real.
To quote numers from Mateusz:
"Sapphire Rapids, will-it-scale, ops/s
stock fstat 5088199
patched fstat 7625244 (+49%)
real fstat 8540383 (+67% / +12%)"
where that 'stock fstat' is the glibc translation of fstat into
fstatat() with an empty path, the 'patched fstat' is with this short
circuiting of the path lookup, and the 'real fstat' is the actual native
fstat() system call with none of this overhead.

This reverts commit b484a40dc1f16edb58e5430105a021e1916e6f27.
This commit cancels all requests with io-wq, not just the ones from the
originating task. This breaks use cases that have thread pools, or just
multiple tasks issuing requests on the same ring. The liburing
regression test for this also shows that problem:
$ test/thread-exit.t
cqe->res=-125, Expected 512
where an IO thread gets its request canceled rather than complete
successfully.

====================
netfilter updates for net
This PR contains nf_tables updates for your *net* tree.
This time almost all fixes are for old bugs:
First patch fixes a 4-byte stack OOB write, from myself.
This was broken ever since nftables was switches from 128 to 32bit
register addressing in v4.1.
2nd patch fixes an out-of-bounds read.
This has been broken ever since xt_osf got added in 2.6.31, the bug
was then just moved around during refactoring, from Wander Lairson Costa.
3rd patch adds a missing enum description, from Phil Sutter.
4th patch fixes a UaF inftables that occurs when userspace adds
elements with a timeout so small that expiration happens while the
transaction is still in progress. Fix from Pablo Neira Ayuso.
Patch 5 fixes a memory out of bounds access, this was
broken since v4.20. Patch from Kyle Zeng and Jozsef Kadlecsik.
Patch 6 fixes another bogus memory access when building audit
record. Bug added in the previous pull request, fix from Pablo.

We hope that tc qdisc and dcb ets commands can not be used crosswise.
If we want to use any of the commands to configure tc,
We must use the other command to clear the existing configuration.
However, when we configure a single tc with tc qdisc,
we can still configure it with dcb ets.
Because we use mqprio_active as the tag of tc qdisc configuration,
but with dcb ets, we do not check mqprio_active.
This patch fix this issue by check mqprio_active before
executing the dcb ets command. and add dcb_ets_active to
replace HCLGE_FLAG_DCB_ENABLE and HCLGE_FLAG_MQPRIO_ENABLE

packet and napi poll scheduling are fast enough, it may get

The KSZ9477 errata points out (in 'Module 4') the link up/down problems
when EEE (Energy Efficient Ethernet) is enabled in the device to which
the KSZ9477 tries to auto negotiate.
The suggested workaround is to clear advertisement of EEE for PHYs in
this chip driver.
To avoid regressions with other switch ICs the new MICREL_NO_EEE flag
has been introduced.
Moreover, the in-register disablement of MMD_DEVICE_ID_EEE_ADV.MMD_EEE_ADV
MMD register is removed, as this code is both; now executed too late
(after previous rework of the PHY and DSA for KSZ switches) and not
required as setting all members of eee_broken_modes bit field prevents
the KSZ9477 from advertising EEE.

For DRM legacy gamma, AMD display manager applies implicit sRGB degamma
using a pre-defined sRGB transfer function. It works fine for DCN2
family where degamma ROM and custom curves go to the same color block.
But, on DCN3+, degamma is split into two blocks: degamma ROM for
pre-defined TFs and `gamma correction` for user/custom curves and
degamma ROM settings doesn't apply to cursor plane. To get DRM legacy
gamma working as expected, enable cursor degamma ROM for implict sRGB
degamma on HW with this configuration.

System runs at minimum performance, once powercap RAPL package domain
enabled flag is changed from 1 to 0 to 1.
Setting RAPL package domain enabled flag to 0, results in setting of
power limit 4 (PL4) MSR 0x601 to 0. This implies disabling PL4 limit.
The PL4 limit controls the peak power. So setting 0, results in some
undesirable performance, which depends on hardware implementation.
Even worse, when the enabled flag is set to 1 again. This will set PL4
MSR value to 0x01, which means reduce peak power to 0.125W. This will
force system to run at the lowest possible performance on every PL4
supported system.
Setting enabled flag should only affect the "enable" bit, not other
bits. Here it is changing power limit.
This is caused by a change which assumes that there is an enable bit in
the PL4 MSR like other power limits. Although PL4 enable/disable bit is
present with TPMI RAPL interface, it is not present with the MSR
interface.
There is a rapl_primitive_info defined for non existent PL4 enable bit
and then it is used with the commit 9050a9cd5e4c ("powercap: intel_rapl:
Cleanup Power Limits support") to enable PL4. This is wrong, hence remove
this rapl primitive for PL4. Also in the function
rapl_detect_powerlimit(), PL_ENABLE is used to check for the presence of
power limits. Replace PL_ENABLE with PL_LIMIT, as PL_LIMIT must be
present. Without this change, PL4 controls will not be available in the
sysfs once rapl primitive for PL4 is removed.

Mostafa reports that commit d232606773a0 ("arm64/sysreg: refactor

original code is working on space-delimited substrings rather than
NUL-terminated strings.
Rather than simply reverting the broken conversion patch, replace the
strscpy() with a simple memcpy() with an explicit NUL-termination of the
result.

1/8 of kernel addresses reserved for shadow memory. But for LoongArch,
There are a lot of holes between different segments and valid address
space (256T available) is insufficient to map all these segments to kasan
shadow memory with the common formula provided by kasan core, saying
(addr >> KASAN_SHADOW_SCALE_SHIFT) + KASAN_SHADOW_OFFSET
So LoongArch has a arch-specific mapping formula, different segments are
mapped individually, and only limited space lengths of these specific
segments are mapped to shadow.
At early boot stage the whole shadow region populated with just one
physical page (kasan_early_shadow_page). Later, this page is reused as
readonly zero shadow for some memory that kasan currently don't track.
After mapping the physical memory, pages for shadow memory are allocated
and mapped.
Functions like memset()/memcpy()/memmove() do a lot of memory accesses.
If bad pointer passed to one of these function it is important to be
caught. Compiler's instrumentation cannot do this since these functions
are written in assembly.
KASan replaces memory functions with manually instrumented variants.
Original functions declared as weak symbols so strong definitions in
mm/kasan/kasan.c could replace them. Original functions have aliases
with '__' prefix in names, so we could call non-instrumented variant
if needed.

Modified relocate_kernel() doesn't return new kernel's entry point but
the random_offset. In this way we share the start_kernel() processing
with the normal kernel, which avoids calling 'jr a0' directly and allows
some other operations (e.g, kasan_early_init) before start_kernel() when
KASLR (CONFIG_RANDOMIZE_BASE) is turned on.

MIPS, LoongArch and some other architectures have many holes between
different segments and the valid address space (256T available) is
insufficient to map all these segments to kasan shadow memory with the
common formula provided by kasan core. So we need architecture specific
mapping formulas to ensure different segments are mapped individually,
and only limited space lengths of those specific segments are mapped to
shadow.
Therefore, when the incoming address is converted to a shadow, we need
to add a condition to determine whether it is valid.

The LoongArch architecture is quite different from other architectures.
When the allocating of KFENCE itself is done, it is mapped to the direct
mapping configuration window [1] by default on LoongArch. It means that
it is not possible to use the page table mapped mode which required by
the KFENCE system and therefore it should be remapped to the appropriate
region.
This patch adds architecture specific implementation details for KFENCE.
In particular, this implements the required interface in <asm/kfence.h>.
Tested this patch by running the testcases and all passed.

Currently, arch_stack_walk() can only get the full stack information
including NMI. This is because the implementation of arch_stack_walk()
is forced to ignore the information passed by the regs parameter and use
the current stack information instead.
For some detection systems like KFENCE, only partial stack information
is needed. In particular, the stack frame where the interrupt occurred.
To support KFENCE, this patch modifies the implementation of the
arch_stack_walk() function so that if this function is called with the
regs argument passed, it retains all the stack information in regs and
uses it to provide accurate information.
