Subject: [PATCH] asmlinkage, x86: Remove leftover extern __visible
From: Andi Kleen <ak@...ux.intel.com>
Remove the left over extern __visible Linus objected too.
They should be useless, as we only need the visible
on the actual definitions.
Mostly for x86, but one in export.h too.
Signed-off-by: Andi Kleen <ak@...ux.intel.com>
