Subsequently all DBG_MDSCR_* macros become redundant and hence can be dropped off completely. While here convert all variables handling MDSCR_EL1 register as u64 which reflects its true width as well. This series applies on v6.16-rc1 Changes in V3: - Split out the self test changes into a separate patch per Mark - Added RB tag from Ada Changes in V2: https://lore.kernel.org/all/20250508044752.234543-1-anshuman.khandual@arm.com/ - Changed reg, val width to u64 in cortex_a76_erratum_1463225_svc_handler() per Ada - Changed mdscr register width to uint64_t in enable_monitor_debug_exceptions() and install_ss() per Ada Changes in V1: https://lore.kernel.org/all/20250417105253.3188976-1-anshuman.khandual@arm.com/ Cc: Catalin Marinas Cc: Will Deacon Cc: Mark Rutland Cc: Ada Couprie Diaz Cc: linux-arm-kernel@lists.infradead.org Cc: linux-kernel@vger.kernel.org Anshuman Khandual (2): arm64/debug: Drop redundant DBG_MDSCR_* macros KVM: selftests: Change MDSCR_EL1 register holding variables as uint64_t arch/arm64/include/asm/assembler.h | 4 ++-- arch/arm64/include/asm/debug-monitors.h | 6 ----- arch/arm64/kernel/debug-monitors.c | 22 +++++++++---------- arch/arm64/kernel/entry-common.c | 4 ++-- .../selftests/kvm/arm64/debug-exceptions.c | 4 ++-- 5 files changed, 17 insertions(+), 23 deletions(-) -- 2.25.1
