Subject: [PATCH 4.14 078/167] x86/speculation: Add <asm/msr-index.h> dependency

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Peter Zijlstra <peterz@...radead.org>

commit ea00f301285ea2f07393678cd2b6057878320c9d upstream.

Joe Konno reported a compile failure resulting from using an MSR
without inclusion of <asm/msr-index.h>, and while the current code builds
fine (by accident) this needs fixing for future patches.
