Pull modules updates from Sami Tolvanen:
- Add a missing return value check for module_extend_max_pages() to
prevent a kernel oops on memory allocation failure.
- Force sh_addr to 0 for architecture-specific module sections on arm,
arm64, m68k, and riscv. This prevents non-zero section addresses when
linking modules with ld.bfd -r, which may cause tools to misbehave
and result in worse compressibility.
- Replace pr_warn! with pr_warn_once! for set_param null pointer
warnings in Rust abstractions, now that the _once variant is
available.

Pull ARM fixes from Russell King:
- Avoid KASAN instrumentation of half-word IO
- Use a byte load for KASAN shadow stack
- Fix kexec and hibernation with PAN
* tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rmk/linux:
ARM: 9476/1: mm: fix kexec and hibernation with CONFIG_CPU_TTBR0_PAN
ARM: 9475/1: entry: use byte load for KASAN VMAP stack shadow
ARM: 9474/1: io: avoid KASAN instrumentation of raw halfword I/O
|
|
For CPUs before ARMv6, __raw_readw() and __raw_writew() are implemented
as C volatile halfword accesses so the compiler can generate an access
sequence that is safe for those machines. With KASAN enabled, those C
accesses are instrumented as normal memory accesses.
That is not valid for MMIO. On ARM926/VersatilePB with KASAN enabled,
PL011 probing traps in __asan_store2() while registering the UART, because
the instrumented writew() tries to check KASAN shadow for an MMIO address.
Keep the existing volatile halfword access, but move the ARMv5 definitions
into __no_kasan_or_inline functions so raw MMIO halfword accesses are not
instrumented by KASAN. The ARMv6-and-newer inline assembly path is
unchanged.

The do_bad_IRQ() macro simply calls handle_bad_irq() with a lock around
it. It also carries a comment stating that uses of it should be
replaced. According to commit aec0095653cd ("irqchip: gic: Call
handle_bad_irq() directly"), which replaced another use of
do_bad_IRQ(), locking the IRQ descriptor is not necessary for error
reporting. Therefore, replace all uses of do_bad_IRQ() with calls to
handle_bad_irq() and remove do_bad_IRQ().

The kernel allows arches to select between inline and outline
implementations of the copy_{from,to}_user() by defining individual
INLINE_COPY_FROM_USER and INLINE_COPY_TO_USER, correspondingly. However,
all arches enable or disable them always together.
Without the real use-case for one helper being inlined while the other
outlined, having independent controls is excessive and error prone.
Switch the codebase to the single unified INLINE_COPY_USER control.

When linking modules with 'ld.bfd -r', sections defined without an address
inherit the location counter, resulting in non-zero sh_addr values in the
resulting .ko files. Relocatable objects are expected to have sh_addr=0 for
all sections. Non-zero addresses are confusing in this context, typically
worse compressible, and may cause tools to misbehave [1].
Force sh_addr=0 for all arm-specific module sections.

On real hardware, panic and machine reboot may not flush hardware cache
to memory. This means the persistent ring buffer, which relies on a
coherent state of memory, may not have its events written to the buffer
and they may be lost. Moreover, there may be inconsistency with the
counters which are used for validation of the integrity of the
persistent ring buffer which may cause all data to be discarded.
To avoid this issue, stop recording of the ring buffer on panic and
flush the cache of the ring buffer's memory.

While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a macro that
only gets defined by the Makefiles in the kernel.
This can be very confusing when switching between userspace and kernelspace
coding, or when dealing with uapi headers that rather should use
__ASSEMBLER__ instead.
Standardize now on the __ASSEMBLER__ macro that is provided by the
compilers.

- "ocfs2/dlm: fix two bugs in dlm_match_regions()" (Junrui Luo)
- "cleanup the RAID5 XOR library" (Christoph Hellwig)
A quite far-reaching cleanup to this code. I can't do better than to
quote Christoph:
"The XOR library used for the RAID5 parity is a bit of a mess right
now. The main file sits in crypto/ despite not being cryptography
and not using the crypto API, with the generic implementations
sitting in include/asm-generic and the arch implementations
sitting in an asm/ header in theory. The latter doesn't work for
many cases, so architectures often build the code directly into
the core kernel, or create another module for the architecture
code.
Change this to a single module in lib/ that also contains the
architecture optimizations, similar to the library work Eric
Biggers has done for the CRC and crypto libraries later. After
that it changes to better calling conventions that allow for
smarter architecture implementations (although none is contained
here yet), and uses static_call to avoid indirection function call
overhead"

Pull arm64 updates from Catalin Marinas:
"The biggest changes are MPAM enablement in drivers/resctrl and new PMU
support under drivers/perf.
On the core side, FEAT_LSUI lets futex atomic operations with EL0
permissions, avoiding PAN toggling.
The rest is mostly TLB invalidation refactoring, further generic entry
work, sysreg updates and a few fixes.
Core features:
- Add support for FEAT_LSUI, allowing futex atomic operations without
toggling Privileged Access Never (PAN)
- Further refactor the arm64 exception handling code towards the
generic entry infrastructure
- Optimise __READ_ONCE() with CONFIG_LTO=y and allow alias analysis
through it
Memory management:
- Refactor the arm64 TLB invalidation API and implementation for
better control over barrier placement and level-hinted invalidation
- Enable batched TLB flushes during memory hot-unplug
- Fix rodata=full block mapping support for realm guests (when
BBML2_NOABORT is available)
Perf and PMU:
- Add support for a whole bunch of system PMUs featured in NVIDIA's
Tegra410 SoC (cspmu extensions for the fabric and PCIe, new drivers
for CPU/C2C memory latency PMUs)
- Clean up iomem resource handling in the Arm CMN driver
- Fix signedness handling of AA64DFR0.{PMUVer,PerfMon}
MPAM (Memory Partitioning And Monitoring):
- Add architecture context-switch and hiding of the feature from KVM
- Add interface to allow MPAM to be exposed to user-space using
resctrl
- Add errata workaround for some existing platforms
- Add documentation for using MPAM and what shape of platforms can
use resctrl
Miscellaneous:
- Check DAIF (and PMR, where relevant) at task-switch time
- Skip TFSR_EL1 checks and barriers in synchronous MTE tag check mode
(only relevant to asynchronous or asymmetric tag check modes)
- Remove a duplicate allocation in the kexec code
- Remove redundant save/restore of SCS SP on entry to/from EL0
- Generate the KERNEL_HWCAP_ definitions from the arm64 hwcap
descriptions
- Add kselftest coverage for cmpbr_sigill()
- Update sysreg definitions"

In order to be able to do this, we need to change VM_DATA_DEFAULT_FLAGS
and friends and update the architecture-specific definitions also.
We then have to update some KSM logic to handle VMA flags, and introduce
VMA_STACK_FLAGS to define the vma_flags_t equivalent of VM_STACK_FLAGS.
We also introduce two helper functions for use during the time we are
converting legacy flags to vma_flags_t values - vma_flags_to_legacy() and
legacy_to_vma_flags().
This enables us to iteratively make changes to break these changes up into
separate parts.
We use these explicitly here to keep VM_STACK_FLAGS around for certain
users which need to maintain the legacy vm_flags_t values for the time
being.
We are no longer able to rely on the simple VM_xxx being set to zero if
the feature is not enabled, so in the case of VM_DROPPABLE we introduce
VMA_DROPPABLE as the vma_flags_t equivalent, which is set to
EMPTY_VMA_FLAGS if the droppable flag is not available.
While we're here, we make the description of do_brk_flags() into a kdoc
comment, as it almost was already.
We use vma_flags_to_legacy() to not need to update the vm_get_page_prot()
logic as this time.
Note that in create_init_stack_vma() we have to replace the BUILD_BUG_ON()
with a VM_WARN_ON_ONCE() as the tested values are no longer build time
available.
We also update mprotect_fixup() to use VMA flags where possible, though we
have to live with a little duplication between vm_flags_t and vma_flags_t
values for the time being until further conversions are made.
While we're here, update VM_SPECIAL to be defined in terms of
VMA_SPECIAL_FLAGS now we have vma_flags_to_legacy().
Finally, we update the VMA tests to reflect these changes.

Reduce 22 declarations of empty_zero_page to 3 and 23 declarations of
ZERO_PAGE() to 4.
Every architecture defines empty_zero_page that way or another, but for the
most of them it is always a page aligned page in BSS and most definitions
of ZERO_PAGE do virt_to_page(empty_zero_page).
Move Linus vetted x86 definition of empty_zero_page and ZERO_PAGE() to the
core MM and drop these definitions in architectures that do not implement
colored zero page (MIPS and s390).
ZERO_PAGE() remains a macro because turning it to a wrapper for a static
inline causes severe pain in header dependencies.
For the most part the change is mechanical, with these being noteworthy:
* alpha: aliased empty_zero_page with ZERO_PGE that was also used for boot
parameters. Switching to a generic empty_zero_page removes the aliasing
and keeps ZERO_PGE for boot parameters only
* arm64: uses __pa_symbol() in ZERO_PAGE() so that definition of
ZERO_PAGE() is kept intact.
* m68k/parisc/um: allocated empty_zero_page from memblock,
although they do not support zero page coloring and having it in BSS
will work fine.
* sparc64 can have empty_zero_page in BSS rather allocate it, but it
can't use virt_to_page() for BSS. Keep it's definition of ZERO_PAGE()
but instead of allocating it, make mem_map_zero point to
empty_zero_page.
* sh: used empty_zero_page for boot parameters at the very early boot.
Rename the parameters page to boot_params_page and let sh use the generic
empty_zero_page.
* hexagon: had an amusing comment about empty_zero_page
/* A handy thing to have if one has the RAM. Declared in head.S */
that unfortunately had to go :)

Move the asm/xor.h headers to lib/raid/xor/$(SRCARCH)/xor_arch.h and
include/linux/raid/xor_impl.h to lib/raid/xor/xor_impl.h so that the
xor.ko module implementation is self-contained in lib/raid/.
As this remove the asm-generic mechanism a new kconfig symbol is added to
indicate that a architecture-specific implementations exists, and
xor_arch.h should be included.

The current logic to split the 64-bit argument into its 32-bit halves is
byte-order specific and a bit clunky. Use a union instead which is
easier to read and works in all cases.
GCC still generates the same machine code.
While at it, rename the arguments of the __memset64() prototype to
actually reflect their semantics.
