Arnaldo Carvalho de Melo 376a947653 tools headers UAPI: Sync files changed by the memfd_secret new syscall 
To pick the changes in this cset:

  7bb7f2ac24 ("arch, mm: wire up memfd_secret system call where relevant")

That silences these perf build warnings and add support for those new
syscalls in tools such as 'perf trace'.

For instance, this is now possible:

  # perf trace -v -e memfd_secret
  event qualifier tracepoint filter: (common_pid != 13375 && common_pid != 3713) && (id == 447)
  ^C#

That is the filter expression attached to the raw_syscalls:sys_{enter,exit}
tracepoints.

  $ grep memfd_secret tools/perf/arch/x86/entry/syscalls/syscall_64.tbl
  447    common  memfd_secret            sys_memfd_secret
  $

This addresses these perf build warnings:

  Warning: Kernel ABI header at 'tools/arch/arm64/include/uapi/asm/unistd.h' differs from latest version at 'arch/arm64/include/uapi/asm/unistd.h'
  diff -u tools/arch/arm64/include/uapi/asm/unistd.h arch/arm64/include/uapi/asm/unistd.h

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.
