From 1965aae3c98397aad957412413c07e97b1bd4e64 Mon Sep 17 00:00:00 2001
From: "H. Peter Anvin" <hpa@zytor.com>

Subject: x86: Fix ASM_X86__ header guards

Change header guards named "ASM_X86__*" to "_ASM_X86_*" since:

a. the double underscore is ugly and pointless.
b. no leading underscore violates namespace constraints.
