Subject: [PATCH 2/4] asmlinkage, x86: Add explicit __visible to arch/x86/*

From: Andi Kleen <ak@...ux.intel.com>

As requested by Linus add explicit __visible to the asmlinkage users.
This marks both functions visible to assembler and some functions
defined in assembler to make it clear to the  compiler that they
exist elsewhere.

Tree sweep for most of arch/x86/*
