Subject[PATCH AUTOSEL 5.5 098/542] x86/alternatives: add missing insn.h include
Date
From: Dave Hansen <dave.hansen@linux.intel.com>

[ 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

Fixes: c3d6324f841b ("x86/alternatives: Teach text_poke_bp() to emulate instructions")
