AMD's next generation of EPYC processors support the MPK (Memory Protection Keys) feature. AMD documentation for MPK feature is available at "AMD64 Architecture Programmer’s Manual Volume 2: System Programming, Pub. 24593 Rev. 3.34, Section 5.6.6 Memory Protection Keys (MPK) Bit". The documentation can be obtained at the link below: https://bugzilla.kernel.org/show_bug.cgi?id=206537 This series enables the feature on AMD and updates config parameters to reflect the MPK support on generic x86 platforms. --- Babu Moger (2): arch/x86: Rename config X86_INTEL_MEMORY_PROTECTION_KEYS to generic x86 KVM: SVM: Add support for MPK feature on AMD Documentation/core-api/protection-keys.rst | 3 ++- arch/x86/Kconfig | 6 +++--- arch/x86/include/asm/disabled-features.h | 4 ++-- arch/x86/include/asm/mmu.h | 2 +- arch/x86/include/asm/mmu_context.h | 4 ++-- arch/x86/include/asm/pgtable.h | 4 ++-- arch/x86/include/asm/pgtable_types.h | 2 +- arch/x86/include/asm/special_insns.h | 2 +- arch/x86/include/uapi/asm/mman.h | 2 +- arch/x86/kernel/cpu/common.c | 2 +- arch/x86/kvm/svm/svm.c | 20 ++++++++++++++++++++ arch/x86/kvm/svm/svm.h | 2 ++ arch/x86/mm/Makefile | 2 +- arch/x86/mm/pkeys.c | 2 +- scripts/headers_install.sh | 2 +- tools/arch/x86/include/asm/disabled-features.h | 4 ++-- 16 files changed, 43 insertions(+), 20 deletions(-) --
