Marc Zyngier 2d84f3ce5e Merge branch kvm-arm64/mmu/mapping-levels into kvmarm-master/next
Revamp the KVM/arm64 THP code by parsing the userspace
page tables instead of relying on an infrastructure that
is about to disappear (we are the last user).

* kvm-arm64/mmu/mapping-levels:
  KVM: Get rid of kvm_get_pfn()
  KVM: arm64: Use get_page() instead of kvm_get_pfn()
  KVM: Remove kvm_is_transparent_hugepage() and PageTransCompoundMap()
  KVM: arm64: Avoid mapping size adjustment on permission fault
  KVM: arm64: Walk userspace page tables to compute the THP mapping size
  KVM: arm64: Introduce helper to retrieve a PTE and its level

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.
