Thank you!
Hi Linus, Please pull the arm64 updates for 5.15 below. The asymmetric AArch32 support patches were queued via tip/sched/arm64 on top of the scheduler counterpart. I merged the tip branch into the arm64 tree (based on -rc3) but since the former was based on -rc6, I had to generate the diffstat manually (dummy merge with upstream and git show --stat). Hopefully it matches yours. Thanks. The following changes since commit 234b8ab6476c5edd5262e2ff563de9498d60044a: sched: Introduce dl_task_check_affinity() to check proposed affinity (2021-08-20 12:33:00 +0200) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux tags/arm64-upstream for you to fetch changes up to 65266a7c6abfa1ad915a362c41bf38576607f1f9: Merge remote-tracking branch 'tip/sched/arm64' into for-next/core (2021-08-31 09:10:00 +0100) ---------------------------------------------------------------- arm64 updates for 5.15: - Support for 32-bit tasks on asymmetric AArch32 systems (on top of the scheduler changes merged via the tip tree). - More entry.S clean-ups and conversion to C. - MTE updates: allow a preferred tag checking mode to be set per CPU (the overhead of synchronous mode is smaller for some CPUs than others); optimisations for kernel entry/exit path; optionally disable MTE on the kernel command line. - Kselftest improvements for SVE and signal handling, PtrAuth. - Fix unlikely race where a TLBI could use stale ASID on an ASID roll-over (found by inspection). - Miscellaneous fixes: disable trapping of PMSNEVFR_EL1 to higher exception levels; drop unnecessary sigdelsetmask() call in the signal32 handling; remove BUG_ON when failing to allocate SVE state (just signal the process); SYM_CODE annotations. - Other trivial clean-ups: use macros instead of magic numbers, remove redundant returns, typos. ---------------------------------------------------------------- Alexandru Elisei (1): arm64: Do not trap PMSNEVFR_EL1 Anshuman Khandual (2): arm64/kexec: Test page size support with new TGRAN range values arm64/perf: Replace '0xf' instances with ID_AA64DFR0_PMUVER_IMP_DEF Catalin Marinas (3): Merge branches 'for-next/mte', 'for-next/misc' and 'for-next/kselftest', remote-tracking branch 'arm64/for-next/perf' into for-next/core Merge branch 'for-next/entry' into for-next/core Merge remote-tracking branch 'tip/sched/arm64' into for-next/core Changbin Du (1): arm64: replace in_irq() with in_hardirq() Jason Wang (3): arm64: use __func__ to get function name in pr_err arm64: unnecessary end 'return;' in void functions arm64: fix typo in a comment Lingyan Huang (1): arm64: SSBS/DIT: print SSBS and DIT bit when printing PSTATE Marc Zyngier (1): arm64: Document the requirement for SCR_EL3.HCE Mark Brown (19): arm64/sme: Document boot requirements for SME kselftest/arm64: Ignore check_gcr_el1_cswitch binary arm64/sve: Make fpsimd_bind_task_to_cpu() static kselftest/arm64: Provide a helper binary and "library" for SVE RDVL kselftest/arm64: Validate vector lengths are set in sve-probe-vls kselftest/arm64: Add tests for SVE vector configuration kselftest/arm64: Add a TODO list for floating point tests arm64: entry: Add SYM_CODE annotation for __bad_stack kselftest/arm64: mte: Fix misleading output when skipping tests kselftest/arm64: pac: Fix skipping of tests on systems without PAC kselftest/arm64: signal: Add SVE to the set of features we can check for kselftest/arm64: signal: Support signal frames with SVE register data kselftest/arm64: signal: Check SVE signal frame shows expected vector length kselftest/arm64: signal: Verify that signals can't change the SVE vector length kselftest/arm64: signal: Add test case for SVE register state in signals kselftest/arm64: signal: Add a TODO list for signal handling tests arm64/sve: Add some comments for sve_save/load_state() arm64/sve: Add a comment documenting the binutils needed for SVE asm arm64/sve: Better handle failure to allocate SVE register storage Mark Rutland (7): arm64: kasan: mte: use a constant kernel GCR_EL1 value arm64: kasan: mte: remove redundant mte_report_once logic arm64: entry: consolidate entry/exit helpers arm64: entry: clarify entry/exit helpers arm64: entry: move bulk of ret_to_user to C arm64: entry: call exit_to_user_mode() from C arm64: head: avoid over-mapping in map_memory Masahiro Yamada (1): arm64: move the (z)install rules to arch/arm64/Makefile Peter Collingbourne (8): arm64: mte: avoid TFSRE0_EL1 related operations unless in async mode arm64: mte: rename gcr_user_excl to mte_ctrl arm64: mte: change ASYNC and SYNC TCF settings into bitfields arm64: move preemption disablement to prctl handlers arm64: mte: introduce a per-CPU tag checking mode preference Documentation: document the preferred tag checking mode feature arm64: mte: optimize GCR_EL1 modification on kernel entry/exit arm64: avoid double ISB on kernel entry Peter Zijlstra (1): Merge branch 'sched/core' Shaokun Zhang (1): arm64: cpufeature: Use defined macro instead of magic numbers Will Deacon (9): arm64: mm: Fix TLBI vs ASID rollover arm64: Implement task_cpu_possible_mask() arm64: exec: Adjust affinity for compat tasks with mismatched 32-bit EL0 arm64: Prevent offlining first CPU with 32-bit EL0 on mismatched system arm64: Advertise CPUs capable of running 32-bit applications in sysfs arm64: Hook up cmdline parameter to allow mismatched 32-bit EL0 arm64: Remove logic to kill 32-bit tasks on 64-bit-only cores Documentation: arm64: describe asymmetric 32-bit support arm64: signal32: Drop pointless call to sigdelsetmask() Xujun Leng (1): arm64: mm: fix comment typo of pud_offset_phys() Yee Lee (1): arm64/cpufeature: Optionally disable MTE via command-line Documentation/ABI/testing/sysfs-devices-system-cpu | 26 + Documentation/admin-guide/kernel-parameters.txt | 14 + Documentation/arm64/asymmetric-32bit.rst | 155 ++++++ Documentation/arm64/booting.rst | 37 +- Documentation/arm64/index.rst | 1 + Documentation/arm64/memory-tagging-extension.rst | 48 +- arch/arm64/Makefile | 7 +- arch/arm64/boot/Makefile | 8 -
