The first fixes a regression introduced during the merge window where the KVM UUID (which is used to advertise KVM-specific hypercalls for things like time synchronisation in the guest) was corrupted thanks to an endianness bug introduced when converting the code to use the UUID_INIT() helper. The second fixes a stack-pointer corruption issue during context-switch which has been observed in the wild when taking a pseudo-NMI with shadow call stack enabled. Please pull. Cheers, Will --->8 The following changes since commit 9dd1757493416310a5e71146a08bc228869f8dae: arm64/mm: Drop wrong writes into TCR2_EL1 (2025-07-04 16:46:04 +0100) 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 d42e6c20de6192f8e4ab4cf10be8c694ef27e8cb: arm64/entry: Mask DAIF in cpu_switch_to(), call_on_irq_stack() (2025-07-22 16:39:30 +0100) ---------------------------------------------------------------- arm64 fixes for 6.16 - Fix broken UUID value for the KVM/arm64 hypervisor SMCCC interface. - Fix stack corruption on context-switch, primarily seen on (but not limited to) configurations with both pNMI and SCS enabled. ---------------------------------------------------------------- Ada Couprie Diaz (1): arm64/entry: Mask DAIF in cpu_switch_to(), call_on_irq_stack() Jack Thomson (1): arm64: kvm, smccc: Fix vendor uuid arch/arm64/include/asm/assembler.h | 5 +++++ arch/arm64/kernel/entry.S | 6 ++++++ include/linux/arm-smccc.h | 2 +- 3 files changed, 12 insertions(+), 1 deletion(-)
