Normally it's Will handling the fixes this time around but he's fishing on some remote lake away from the modern world (and internet connection). Thanks. The following changes since commit 3a8660878839faadb4f1a6dd72c3179c1df56787: Linux 6.18-rc1 (2025-10-12 13:42:36 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux tags/arm64-fixes for you to fetch changes up to ea0d55ae4b3207c33691a73da3443b1fd379f1d2: arm64: debug: always unmask interrupts in el0_softstp() (2025-10-17 18:08:05 +0100) ---------------------------------------------------------------- arm64 fixes: - Explicitly encode the XZR register if the value passed to write_sysreg_s() is 0. The GIC CDEOI instruction is encoded as a system register write with XZR as the source register. However, clang does not honour the "Z" register constraint, leading to incorrect code generation - Ensure the interrupts (DAIF.IF) are unmasked when completing single-step of a suspended breakpoint before calling exit_to_user_mode(). With pseudo-NMIs, interrupts are (additionally) masked at the PMR_EL1 register, handled by local_irq_*() ---------------------------------------------------------------- Ada Couprie Diaz (1): arm64: debug: always unmask interrupts in el0_softstp() Lorenzo Pieralisi (1): arm64/sysreg: Fix GIC CDEOI instruction encoding arch/arm64/include/asm/sysreg.h | 11 ++++++++++- arch/arm64/kernel/entry-common.c | 8 +++++--- 2 files changed, 15 insertions(+), 4 deletions(-) -- Catalin
