Pull kvm fixes from Paolo Bonzini:
"ARM:
- Rework of system register accessors for system registers that are
directly writen to memory, so that sanitisation of the in-memory
value happens at the correct time (after the read, or before the
write). For convenience, RMW-style accessors are also provided.
- Multiple fixes for the so-called "arch-timer-edge-cases' selftest,
which was always broken.
x86:
- Make KVM_PRE_FAULT_MEMORY stricter for TDX, allowing userspace to
pass only the "untouched" addresses and flipping the shared/private
bit in the implementation.
- Disable SEV-SNP support on initialization failure
* tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
KVM: x86/mmu: Reject direct bits in gpa passed to KVM_PRE_FAULT_MEMORY
KVM: x86/mmu: Embed direct bits into gpa for KVM_PRE_FAULT_MEMORY
KVM: SEV: Disable SEV-SNP support on initialization failure
KVM: arm64: selftests: Determine effective counter width in arch_timer_edge_cases
KVM: arm64: selftests: Fix xVAL init in arch_timer_edge_cases
KVM: arm64: selftests: Fix thread migration in arch_timer_edge_cases
KVM: arm64: selftests: Fix help text for arch_timer_edge_cases
KVM: arm64: Make __vcpu_sys_reg() a pure rvalue operand
KVM: arm64: Don't use __vcpu_sys_reg() to get the address of a sysreg
KVM: arm64: Add RMW specific sysreg accessor
KVM: arm64: Add assignment-specific sysreg accessor
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 reStructuredText 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.
