Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull kvm fixes from Paolo Bonzini:
 "While last week's pull request contained miscellaneous fixes for x86,
  this one covers other architectures, selftests changes, and a bigger
  series for APIC virtualization bugs that were discovered during 5.20
  development. The idea is to base 5.20 development for KVM on top of
  this tag.

  ARM64:

   - Properly reset the SVE/SME flags on vcpu load

   - Fix a vgic-v2 regression regarding accessing the pending state of a
     HW interrupt from userspace (and make the code common with vgic-v3)

   - Fix access to the idreg range for protected guests

   - Ignore 'kvm-arm.mode=protected' when using VHE

   - Return an error from kvm_arch_init_vm() on allocation failure

   - A bunch of small cleanups (comments, annotations, indentation)

  RISC-V:

   - Typo fix in arch/riscv/kvm/vmid.c

   - Remove broken reference pattern from MAINTAINERS entry

  x86-64:

   - Fix error in page tables with MKTME enabled

   - Dirty page tracking performance test extended to running a nested
     guest

   - Disable APICv/AVIC in cases that it cannot implement correctly"

[ This merge also fixes a misplaced end parenthesis bug introduced in
  commit 3743c2f025 ("KVM: x86: inhibit APICv/AVIC on changes to APIC
  ID or APIC base") pointed out by Sean Christopherson ]

README 

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.
