linux-next: build warning in Linus' tree

[Stephen Rothwell]

Hi Linus,

Just building Linus' tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

warning: objtool: x86 instruction decoder differs from kernel

This is a change since yesterday.  Linus' tree has been updated with
these commits since then:

  4f2ba5dc183b7..ead751507de8

so, I assume this is just due to the SPDX ids being added to files that
objtool cares about.

The perf build also produced lots of Warnings about differences in
include files.
