Marc Zyngier 8cba6c8b87 Merge branch kvm-arm64/52bit-at into kvmarm-master/next
* kvm-arm64/52bit-at:
  : .
  : Upgrade the S1 page table walker to support 52bit PA, and use it to
  : report the fault level when taking a S2 fault on S1PTW, which is required
  : by the architecture (20250915114451.660351-1-maz@kernel.org).
  : .
  KVM: arm64: selftest: Expand external_aborts test to look for TTW levels
  KVM: arm64: Populate level on S1PTW SEA injection
  KVM: arm64: Add S1 IPA to page table level walker
  KVM: arm64: Add filtering hook to S1 page table walk
  KVM: arm64: Don't switch MMU on translation from non-NV context
  KVM: arm64: Allow EL1 control registers to be accessed from the CPU state
  KVM: arm64: Allow use of S1 PTW for non-NV vcpus
  KVM: arm64: Report faults from S1 walk setup at the expected start level
  KVM: arm64: Expand valid block mappings to FEAT_LPA/LPA2 support
  KVM: arm64: Populate PAR_EL1 with 52bit addresses
  KVM: arm64: Compute shareability for LPA2
  KVM: arm64: Pass the walk_info structure to compute_par_s1()
  KVM: arm64: Decouple output address from the PT descriptor
  KVM: arm64: Compute 52bit TTBR address and alignment
  KVM: arm64: Account for 52bit when computing maximum OA
  KVM: arm64: Add helper computing the state of 52bit PA support

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.
