Half of it is broken hardware (AMU counters and TLB invalidation) and the other half is broken software (frequency scaling and signals). So it seems as though we're all as bad as each other. The AMU workaround is a little noisy, as it refactors an existing workaround so that it can more easily be applied to additional CPUs. See you next week, Will --->8 The following changes since commit 2bc6b218717b9d08f466f88209251d54bc09b207: arm64/boot: Disable trapping of PMZR_EL0 writes to EL2 (2026-09-23 12:34:30 +0000) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git tags/arm64-fixes for you to fetch changes up to e060d9069b49fe55f38057dfe592068014652671: arm64/fpsimd: signal: Forbid non-streaming SVE payload on SME-only systems (2026-10-01 15:45:23 +0000) ---------------------------------------------------------------- arm64 fixes for -rc6 - Fix handling of CPU erratum #2645198 when batching pte updates - Fix truncation of CPU frequency calculation by using 64-bit arithmetic in arch_freq_get_on_cpu() - Work around AMU erratum #3821522 on Cortex-A725 - Fix panic when trying to restore an SVE sigframe on a CPU that only supports SME ---------------------------------------------------------------- Andrea Parri (1): arm64: mm: Fix the break-before-make flush range for erratum 2645198 Beata Michalska (2): arm64: errata: Factor out broken AMU const counter cap arm64: errata: Add Cortex-A725 erratum 3821522 workaround Mark Rutland (1): arm64/fpsimd: signal: Forbid non-streaming SVE payload on SME-only systems Oleg Keri (1): arm64: topology: fix arch_freq_get_on_cpu() overflow above 4.19 GHz Documentation/arch/arm64/silicon-errata.rst | 2 ++ arch/arm64/Kconfig | 30 +++++++++++++++++++++++++ arch/arm64/kernel/cpu_errata.c | 24 +++++++++++++++----- arch/arm64/kernel/cpufeature.c | 2 +- arch/arm64/kernel/signal.c | 34 +++++++++++++++++------------ arch/arm64/kernel/topology.c | 22 +++++++++---------- arch/arm64/mm/mmu.c | 2 +- arch/arm64/tools/cpucaps | 2 +- 8 files changed, 84 insertions(+), 34 deletions(-)
