arm64/sme: Fix cut'n'paste in ABI document
The ABI for SME is very like that for SVE so bits of the ABI were copied but not adequately search and replaced, fix that.

arm64/sve: Remove bitrotted comment about syscall behaviour
When we documented that we always clear state not shared with FPSIMD we didn't catch all of the places that mentioned that state might not be cleared, remove a lingering reference.

This does not include the actual KVM-side support which will come from the KVM folks. The TDX host interactions with kexec also needs to be ironed out before this is ready for prime time, so this code is currently Kconfig'd off when kexec is on. The majority of the code here is the kernel telling the TDX module which memory to protect and handing some additional memory over to it to use to store TDX module metadata. That sounds pretty simple, but the TDX architecture is rather flexible and it takes quite a bit of back-and-forth to say, "just protect all memory, please." There is also some code tacked on near the end of the series to handle a hardware erratum. The erratum can make software bugs such as a kernel write to TDX-protected memory cause a machine check and masquerade as a real hardware failure. The erratum handling watches out for these and tries to provide nicer user errors" * tag 'x86_tdx_for_6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (21 commits) x86/virt/tdx: Make TDX host depend on X86_MCE x86/virt/tdx: Disable TDX host support when kexec is enabled Documentation/x86: Add documentation for TDX host support x86/mce: Differentiate real hardware #MCs from TDX erratum ones x86/cpu: Detect TDX partial write machine check erratum x86/virt/tdx: Handle TDX interaction with sleep and hibernation x86/virt/tdx: Initialize all TDMRs x86/virt/tdx: Configure global KeyID on all packages x86/virt/tdx: Configure TDX module with the TDMRs and global KeyID x86/virt/tdx: Designate reserved areas for all TDMRs x86/virt/tdx: Allocate and set up PAMTs for TDMRs x86/virt/tdx: Fill out TDMRs to cover all TDX memory regions x86/virt/tdx: Add placeholder to construct TDMRs to cover all TDX memory regions x86/virt/tdx: Get module global metadata for module initialization x86/virt/tdx: Use all system memory when initializing TDX module as TDX memory x86/virt/tdx: Add skeleton to enable TDX on demand x86/virt/tdx: Add SEAMCALL error printing for module initialization x86/virt/tdx: Handle SEAMCALL no entropy error in common code x86/virt/tdx: Make INTEL_TDX_HOST depend on X86_X2APIC x86/virt/tdx: Define TDX supported page sizes as macros ... |

arm64: errata: Add Cortex-A510 speculative unprivileged load workaround
Implement the workaround for ARM Cortex-A510 erratum 3117295. On an affected Cortex-A510 core, a speculatively executed unprivileged load might leak data from a privileged load via a cache side channel. The issue only exists for loads within a translation regime with the same translation (e.g. same ASID and VMID). Therefore, the issue only affects the return to EL0. The erratum and workaround are the same as ARM Cortex-A520 erratum 2966298, so reuse the existing workaround.

Another moderately busy cycle for documentation, including:
- The minimum Sphinx requirement has been raised to 2.4.4, following a warning that was added in 6.2. - Some reworking of the Documentation/process front page to, hopefully, make it more useful. - Various kernel-doc tweaks to, for example, make it deal properly with __counted_by annotations. - We have also restored a warning for documentation of nonexistent structure members that disappeared a while back. That had the delightful consequence of adding some 600 warnings to the docs build. A sustained effort by Randy, Vegard, and myself has addressed almost all of those, bringing the documentation back into sync with the code. The fixes are going through the appropriate maintainer trees. - Various improvements to the HTML rendered docs, including automatic links to Git revisions and a nice new pulldown to make translations easy to access. - Speaking of translations, more of those for Spanish and Chinese. ...plus the usual stream of documentation updates and typo fixes. -----BEGIN PGP SIGNATURE----- iQFDBAABCAAtFiEEIw+MvkEiF49krdp9F0NaE2wMflgFAmWcRKMPHGNvcmJldEBs d24ubmV0AAoJEBdDWhNsDH5YTKIH/AxBt/3iWt40dPf18arZHLU6tdUbmg01ttef CNKWkniCmABGKc//KYDXvjZMRDt0YlrS0KgUzrb8nIQTBlZG40D+88EwjXE0HeGP xt1Fk7OPOiJEqBZ3HEe0PDVfOiA+4yR6CmDKklCJuKg77X9atklneBwPUw/cOASk CWj+BdbwPBiSNQv48Lp87rGusKwnH/g0MN2uS0z9MPr1DYjM1K8+ngZjGW24lZHt qs5yhP43mlZGBF/lwNJXQp/xhnKAqJ9XwylBX9Wmaoxaz9yyzNVsADGvROMudgzi 9YB+Jdy7Z0JSrVoLIRhUuDOv7aW8vk+8qLmGJt2aTIsqehbQ6pk= =fCtT -----END PGP SIGNATURE----- Merge tag 'docs-6.8' of git://git.lwn.net/linux Pull documentation update from Jonathan Corbet: "Another moderately busy cycle for documentation, including: - The minimum Sphinx requirement has been raised to 2.4.4, following a warning that was added in 6.2 - Some reworking of the Documentation/process front page to, hopefully, make it more useful - Various kernel-doc tweaks to, for example, make it deal properly with __counted_by annotations - We have also restored a warning for documentation of nonexistent structure members that disappeared a while back.

docs: kernel_feat.py: fix potential command injection
The kernel-feat directive passes its argument straight to the shell.
This is unfortunate and unnecessary.
Let's always use paths relative to $srctree/Documentation/ and use
subprocess.check_call() instead of subprocess.Popen(shell=True).
This also makes the code shorter.
This is analogous to commit

RISC-V: hwprobe: Introduce which-cpus flag
Introduce the first flag for the hwprobe syscall. The flag basically reverses its behavior, i.e. instead of populating the values of keys for a given set of cpus, the set of cpus after the call is the result of finding a set which supports the values of the keys. In order to do this, we implement a pair compare function which takes the type of value (a single value vs. a bitmask of booleans) into consideration. We also implement vdso support for the new flag.

RISC-V: hwprobe: Clarify cpus size parameter
The "count" parameter associated with the 'cpus' parameter of the hwprobe syscall is the size in bytes of 'cpus'. Naming it 'cpu_count' may mislead users (it did me) to think it's the number of CPUs that are or can be represented by 'cpus' instead. This is particularly easy (IMO) to get wrong since 'cpus' is documented to be defined by CPU_SET(3) and CPU_SET(3) also documents a CPU_COUNT() (the number of CPUs in set) macro. CPU_SET(3) refers to the size of cpu sets with 'setsize'. Adopt 'cpusetsize' for the hwprobe parameter and specifically state it is in bytes in Documentation/riscv/hwprobe.rst to clarify.

docs: automarkup: linkify git revs
There aren't a ton of references to commits in the documentation, but they do exist, and we can use automarkup to linkify them to make them easier to follow. Use something like this to find references to commits: git grep -P 'commit.*[0-9a-f]{8,}' Documentation/ Also fix a few of these to standardize on the exact format that is already used in changelogs.

coresight: etm: Override TRCIDR3.CCITMIN on errata affected cpus
This work arounds errata 1490853 on Cortex-A76, and Neoverse-N1, errata 1491015 on Cortex-A77, errata 1502854 on Cortex-X1, and errata 1619801 on Neoverse-V1, based affected cpus, where software read for TRCIDR3.CCITMIN field in ETM gets an wrong value. If software uses the value returned by the TRCIDR3.CCITMIN register field, then it will limit the range which could be used for programming the ETM. In reality, the ETM could be programmed with a much smaller value than what is indicated by the TRCIDR3.CCITMIN field and still function correctly. If software reads the TRCIDR3.CCITMIN register field, corresponding to the instruction trace counting minimum threshold, observe the value 0x100 or a minimum cycle count threshold of 256. The correct value should be 0x4 or a minimum cycle count threshold of 4. This work arounds the problem via storing 4 in drvdata->ccitmin on affected systems where the TRCIDR3.CCITMIN has been 256, thus preserving cycle count threshold granularity. These errata information has been updated in Documentation/arch/arm64/silicon-errata.rst, but without their corresponding configs because these have been implemented directly in the driver.

x86/Documentation: Indent 'note::' directive for protocol version number note
The protocol version number note is between the protocol version table and
the memory layout section. As such, Sphinx renders the note directive not
only on the actual note, but until the end of doc.
Indent the directive so that only the actual protocol version number
note is rendered as such.

Pull sh updates from John Paul Adrian Glaubitz:
"While the previously announced patch series for converting arch/sh to
device trees is not yet ready for inclusion to mainline and therefore
didn't make it for this pull request, there are still a small number
changes for v6.7 which include one platform (board plus CPU and driver
code) removal plus two fixes.
The removal sent in by Arnd Bergmann concerns the microdev board which
was an early SuperH prototype board that was never used in production.
With the board removed, we were able to drop the now unused code for
the SH4-202 CPU and well as the driver code for the superhyway bus and
a custom implementation for ioport_map() and ioport_unmap() which will
allow us to simplify ioport handling in the future.

The architecture specific system call tables are updated for the added map_shadow_stack() syscall and to remove references to the long-gone sys_lookup_dcookie() syscall. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmVC40IACgkQYKtH/8kJ Uidhmw/9EX+aWSXGoObJ3fngaNSMw+PmrEuP8qEKBHxfKHcCdX3hc451Oh4GlhaQ tru91pPwgNvN2/rfoKusxT+V4PemGIzfNni/04rp+P0kvmdw5otQ2yNhsQNsfVmq XGWvkxF4P2GO6bkjjfR/1dDq7GtlyXtwwPDKeLbYb6TnJOZjtx+EAN27kkfSn1Ms R4Sa3zJ+DfHUmHL5S9g+7UD/CZ5GfKNmIskI4Mz5GsfoUz/0iiU+Bge/9sdcdSJQ kmbLy5YnVzfooLZ3TQmBFsO3iAMWb0s/mDdtyhqhTVmTUshLolkPYyKnPFvdupyv shXcpEST2XJNeaDRnL2K4zSCdxdbnCZHDpjfl9wfioBg7I8NfhXKpf1jYZHH1de4 LXq8ndEFEOVQw/zSpYWfQq1sux8Jiqr+UK/ukbVeFWiGGIUs91gEWtPAf8T0AZo9 ujkJvaWGl98O1g5wmBu0/dAR6QcFJMDfVwbmlIFpU8O+MEaz6X8mM+O5/T0IyTcD eMbAUjj4uYcU7ihKzHEv/0SS9Of38kzff67CLN5k8wOP/9NlaGZ78o1bVle9b52A BdhrsAefFiWHp1jT6Y9Rg4HOO/TguQ9e6EWSKOYFulsiLH9LEFaB9RwZLeLytV0W vlAgY9rUW77g1OJcb7DoNv33nRFuxsKqsnz3DEIXtgozo9CzbYI= =H1vH -----END PGP SIGNATURE----- Merge tag 'asm-generic-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull ia64 removal and asm-generic updates from Arnd Bergmann: - The ia64 architecture gets its well-earned retirement as planned, now that there is one last (mostly) working release that will be maintained as an LTS kernel. - The architecture specific system call tables are updated for the added map_shadow_stack() syscall and to remove references to the long-gone sys_lookup_dcookie() syscall. * tag 'asm-generic-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: hexagon: Remove unusable symbols from the ptrace.h uapi asm-generic: Fix spelling of architecture arch: Reserve map_shadow_stack() syscall number for all architectures syscalls: Cleanup references to sys_lookup_dcookie() Documentation: Drop or replace remaining mentions of IA64 lib/raid6: Drop IA64 support Documentation: Drop IA64 from feature descriptions kernel: Drop IA64 support from sig_fault handlers arch: Remove Itanium (IA-64) architecture |

arm64 updates for 6.7:
* Major refactoring of the CPU capability detection logic resulting in the removal of the cpus_have_const_cap() function and migrating the code to "alternative" branches where possible * Backtrace/kgdb: use IPIs and pseudo-NMI * Perf and PMU: - Add support for Ampere SoC PMUs - Multi-DTC improvements for larger CMN configurations with multiple Debug & Trace Controllers - Rework the Arm CoreSight PMU driver to allow separate registration of vendor backend modules - Fixes: add missing MODULE_DEVICE_TABLE to the amlogic perf driver; use device_get_match_data() in the xgene driver; fix NULL pointer dereference in the hisi driver caused by calling cpuhp_state_remove_instance(); use-after-free in the hisi driver * HWCAP updates: - FEAT_SVE_B16B16 (BFloat16) - FEAT_LRCPC3 (release consistency model) - FEAT_LSE128 (128-bit atomic instructions) * SVE: remove a couple of pseudo registers from the cpufeature code. There is logic in place already to detect mismatched SVE features * Miscellaneous: - Reduce the default swiotlb size (currently 64MB) if no ZONE_DMA bouncing is needed. The buffer is still required for small kmalloc() buffers - Fix module PLT counting with !RANDOMIZE_BASE - Restrict CPU_BIG_ENDIAN to LLVM IAS 15.x or newer move synchronisation code out of the set_ptes() loop - More compact cpufeature displaying enabled cores - Kselftest updates for the new CPU features -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAmU7/QUACgkQa9axLQDI XvEx3xAAjICmHm+ryKJxS1IGXLYu2DXMcHUjeW6w1SxkK/vKhTMlHRx/CIWDze2l eENu7TcDLtTw+Gv9kqg30TSwzLfJhP9oFpX2T5TKkh5qlJlbz8fBtm+as14DTLCZ p2sra3J0w4B5JwTVqnj2RHOlEftMKvbyLGRkz3ve6wIUbsp5pXMkxAd/k3wOf0lC m6d9w1OMA2sOsw9YCgjcCNQGEzFMJk+13w7K+4w6A8Djn/Jxkt4fAFVn2ZlCiZzD NA2lTDWJqGmeGHo3iFdCTensWXmWTqjzxsNEf7PyBk5mBOdzDVxlTfEL7vnJg7gf BlTQ/nhIpra7rHQ9q2rwqEzbF+4Tn3uWlQfdDb7+/4goPjDh7tlBhEOYyOwTCEIT 0t9cCSvBmSCKeXC3lKWWtJ+QJKhZHSmXN84EotTs65KyyfIsi4RuSezvV/+aIL86 06sHYlYxETuujZP1cgOjf69Wsdsgizx0mqXJXf/xOjp22HFDcL4Bki6Rgi6t5OZj GEHG15kSE+eJ+RIpxpuAN8fdrlxYubsVLIksCqK7cZf9zXbQGIlifKAIrYiEx6kz FD+o+j/5niRWR6yJZCtCcGxqpSlwnYWPqc1Ds0GES8A/BphWMPozXUAZ0ll4Fnp1 yyR2/Due/eBsCNESn579kP8989rashubB8vxvdx2fcWVtLC7VgE= =QaEo -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Catalin Marinas: "No major architecture features this time around, just some new HWCAP definitions, support for the Ampere SoC PMUs and a few fixes/cleanups.
