![]() Pull x86 core updates from Ingo Molnar: "Note that in this cycle most of the x86 topics interacted at a level that caused them to be merged into tip:x86/asm - but this should be a temporary phenomenon, hopefully we'll back to the usual patterns in the next merge window. The main changes in this cycle were: Hardware enablement: - Add support for the Intel UMIP (User Mode Instruction Prevention) CPU feature. This is a security feature that disables certain instructions such as SGDT, SLDT, SIDT, SMSW and STR. (Ricardo Neri) [ Note that this is disabled by default for now, there are some smaller enhancements in the pipeline that I'll follow up with in the next 1-2 days, which allows this to be enabled by default.] - Add support for the AMD SEV (Secure Encrypted Virtualization) CPU feature, on top of SME (Secure Memory Encryption) support that was added in v4.14. (Tom Lendacky, Brijesh Singh) - Enable new SSE/AVX/AVX512 CPU features: AVX512_VBMI2, GFNI, VAES, VPCLMULQDQ, AVX512_VNNI, AVX512_BITALG. (Gayatri Kammela) Other changes: - A big series of entry code simplifications and enhancements (Andy Lutomirski) - Make the ORC unwinder default on x86 and various objtool enhancements. (Josh Poimboeuf) - 5-level paging enhancements (Kirill A. Shutemov) - Micro-optimize the entry code a bit (Borislav Petkov) - Improve the handling of interdependent CPU features in the early FPU init code (Andi Kleen) - Build system enhancements (Changbin Du, Masahiro Yamada) - ... plus misc enhancements, fixes and cleanups" * 'x86-asm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (118 commits) x86/build: Make the boot image generation less verbose selftests/x86: Add tests for the STR and SLDT instructions selftests/x86: Add tests for User-Mode Instruction Prevention x86/traps: Fix up general protection faults caused by UMIP x86/umip: Enable User-Mode Instruction Prevention at runtime x86/umip: Force a page fault when unable to copy emulated result to user x86/umip: Add emulation code for UMIP instructions x86/cpufeature: Add User-Mode Instruction Prevention definitions x86/insn-eval: Add support to resolve 16-bit address encodings x86/insn-eval: Handle 32-bit address encodings in virtual-8086 mode x86/insn-eval: Add wrapper function for 32 and 64-bit addresses x86/insn-eval: Add support to resolve 32-bit address encodings x86/insn-eval: Compute linear address in several utility functions resource: Fix resource_size.cocci warnings X86/KVM: Clear encryption attribute when SEV is active X86/KVM: Decrypt shared per-cpu variables when SEV is active percpu: Introduce DEFINE_PER_CPU_DECRYPTED x86: Add support for changing memory encryption attribute in early boot x86/io: Unroll string I/O when SEV is active x86/boot: Add early boot support when running with SEV active ... |
