Arnaldo Carvalho de Melo 558517c52c tools headers uapi: Sync linux/kvm.h with the kernel sources 
To get the changes from these csets:

  2bc39970e9 ("x86/kvm/hyper-v: Introduce KVM_GET_SUPPORTED_HV_CPUID")
  2a31b9db15 ("kvm: introduce manual dirty log reprotect")

That results in these new KVM IOCTLs being supported in 'perf trace'
when beautifying the cmd ioctl syscall argument:

  $ cp include/uapi/linux/kvm.h tools/include/uapi/linux/kvm.h
  $ tools/perf/trace/beauty/kvm_ioctl.sh > after
  $ diff -u before after

At some point we should be able to do something:

  # perf trace -e ioctl(cmd == KVM_CLEAR_DIRTY_LOG)

And have just those ioctls, optionally with callchains, etc.

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.
