Clean these up via updating required register filed definitions in tools sysreg format and then subsequently doing all necessary replacements. TCR_XXX macros are moved from (asm/pgtable-hwdef.h) into KVM header (asm/kvm_arm.h) for their continued usage in KVM. The cleanup does not cause any functional change. This applies on v6.17-rc4 Cc: Catalin Marinas Cc: Will Deacon Cc: Marc Zyngier Cc: Oliver Upton Cc: Mark Brown Cc: Ryan Roberts Cc: kvmarm@lists.linux.dev Cc: linux-kernel@vger.kernel.org Cc: linux-arm-kernel@lists.infradead.org Changes in V3: - KVM TCR_XXX flags are expressed via TCR_EL1_XXX flags per Marc Changes in V2: https://lore.kernel.org/all/20250829060215.1086792-1-anshuman.khandual@arm.com/ - Fixed ARM ARM version from 7.B to L.B - Changed UnsignedEnum into Enum per Mark - Dropped all TCR_EL1 replacements from KVM code - Moved existing TCR_XXX macros from (asm/pgtable-hwdef.h) into KVM header (asm/kvm_arm.h) for their continued usage - Dropped patches 3 and 4 which could be done subsequently Changes in V1: https://lore.kernel.org/linux-arm-kernel/20250818045759.672408-1-anshuman.khandual@arm.com/ Anshuman Khandual (2): arm64/sysreg: Update TCR_EL1 register arm64/sysreg: Replace TCR_EL1 field macros arch/arm64/include/asm/assembler.h | 6 +- arch/arm64/include/asm/cputype.h | 2 +- arch/arm64/include/asm/kvm_arm.h | 78 ++++++++++++++++++++ arch/arm64/include/asm/mmu_context.h | 4 +- arch/arm64/include/asm/pgtable-hwdef.h | 98 +------------------------- arch/arm64/include/asm/pgtable-prot.h | 2 +- arch/arm64/include/asm/sysreg.h | 2 - arch/arm64/kernel/cpufeature.c | 4 +- arch/arm64/kernel/pi/map_kernel.c | 8 +-- arch/arm64/kernel/vmcore_info.c | 2 +- arch/arm64/mm/proc.S | 36 ++++++---- arch/arm64/tools/sysreg | 52 +++++++++++--- tools/arch/arm64/include/asm/cputype.h | 2 +- 13 files changed, 162 insertions(+), 134 deletions(-) -- 2.25.1
