John Paul Adrian Glaubitz b3962b4e83 ia64: tools: remove duplicate definition of ia64_mf() on ia64 
[ Upstream commit f4bf09dc3aaa4b07cd15630f2023f68cb2668809 ]

The ia64_mf() macro defined in tools/arch/ia64/include/asm/barrier.h is
already defined in <asm/gcc_intrin.h> on ia64 which causes libbpf
failing to build:

        |
  cc1: all warnings being treated as errors

Thus, remove the definition from tools/arch/ia64/include/asm/barrier.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.
