Arnaldo Carvalho de Melo e30dca91e5 tools headers UAPI: Sync kvm headers with the kernel sources 
To pick the changes in:

  a5d3df8ae1 ("KVM: remove deprecated UAPIs")
  6d72283526 ("KVM x86/xen: add an override for PVCLOCK_TSC_STABLE_BIT")
  89ea60c2c7 ("KVM: x86: Add support for "protected VMs" that can utilize private memory")
  8dd2eee9d5 ("KVM: x86/mmu: Handle page fault for private memory")
  a7800aa80e ("KVM: Add KVM_CREATE_GUEST_MEMFD ioctl() for guest-specific backing memory")
  5a475554db ("KVM: Introduce per-page memory attributes")
  16f95f3b95 ("KVM: Add KVM_EXIT_MEMORY_FAULT exit to report faults to userspace")
  bb58b90b1a ("KVM: Introduce KVM_SET_USER_MEMORY_REGION2")
  3f9cd0ca84 ("KVM: arm64: Allow userspace to get the writable masks for feature ID registers")

That automatically adds support for some new ioctls and remove a bunch
of deprecated ones.

This ends up making the new binary to forget about the deprecated one,
so when used in an older system it will not be able to resolve those
codes to strings.

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.
