Pull x86 cpu updates from Borislav Petkov: - Add support for hardware-enforced cache coherency on AMD which obviates the need to flush cachelines before changing the PTE encryption bit (Krish Sadhukhan) - Add Centaur initialization support for families >= 7 (Tony W Wang-oc) - Add a feature flag for, and expose TSX suspend load tracking feature to KVM (Cathy Zhang) - Emulate SLDT and STR so that windows programs don't crash on UMIP machines (Brendan Shanks and Ricardo Neri) - Use the new SERIALIZE insn on Intel hardware which supports it (Ricardo Neri) - Misc cleanups and fixes * tag 'x86_cpu_for_v5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: KVM: SVM: Don't flush cache if hardware enforces cache coherency across encryption domains x86/mm/pat: Don't flush cache if hardware enforces cache coherency across encryption domnains x86/cpu: Add hardware-enforced cache coherency as a CPUID feature x86/cpu/centaur: Add Centaur family >=7 CPUs initialization support x86/cpu/centaur: Replace two-condition switch-case with an if statement x86/kvm: Expose TSX Suspend Load Tracking feature x86/cpufeatures: Enumerate TSX suspend load address tracking instructions x86/umip: Add emulation/spoofing for SLDT and STR instructions x86/cpu: Fix typos and improve the comments in sync_core() x86/cpu: Use XGETBV and XSETBV mnemonics in fpu/internal.h x86/cpu: Use SERIALIZE in sync_core() when available
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
