Oliver Upton 52b603628a Merge branch kvm-arm64/parallel-access-faults into kvmarm/next
* kvm-arm64/parallel-access-faults:
  : Parallel stage-2 access fault handling
  :
  : The parallel faults changes that went in to 6.2 covered most stage-2
  : aborts, with the exception of stage-2 access faults. Building on top of
  : the new infrastructure, this series adds support for handling access
  : faults (i.e. updating the access flag) in parallel.
  :
  : This is expected to provide a performance uplift for cores that do not
  : implement FEAT_HAFDBS, such as those from the fruit company.
  KVM: arm64: Condition HW AF updates on config option
  KVM: arm64: Handle access faults behind the read lock
  KVM: arm64: Don't serialize if the access flag isn't set
  KVM: arm64: Return EAGAIN for invalid PTE in attr walker
  KVM: arm64: Ignore EAGAIN for walks outside of a fault
  KVM: arm64: Use KVM's pte type/helpers in handle_access_fault()

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.
