Subject: [PATCH 1/5] x86/alternatives: add missing insn.h include
Date: Thu, 23 Jan 2020 11:04:58 -0800 [thread overview]
Message-ID: <20200123190458.00285A85@viggo.jf.intel.com> (raw)
In-Reply-To: <20200123190456.8E05ADE6@viggo.jf.intel.com>
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")
