Currently TCR_EL1 field macros are sprinkled across the arm64 platform code including KVM implementation. 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 <catalin.marinas@arm.com> Cc: Will Deacon <will@kernel.org> Cc: Marc Zyngier <maz@kernel.org> Cc: Oliver Upton <redacted> Cc: Mark Brown <broonie@kernel.org> Cc: Ryan Roberts <ryan.roberts@arm.com> 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/ (local) - 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/ (local) 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
