[ Upstream commit 3a1255396b5aba40299d5dd5bde67b160a44117f ]
From: Dave Hansen dave.hansen@linux.intel.com
While testing my MPX removal series, Borislav noted compilation failure with an allnoconfig build.
Turned out to be a missing include of insn.h in alternative.c. With MPX, it got it implicitly from:
asm/mmu_context.h -> asm/mpx.h -> asm/insn.h
