From a454ab3110175d710f4f9a96226a26ce4d5d5de2 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Sun, 3 May 2009 10:09:03 +0200 Subject: [PATCH] x86, mm: fault.c, use printk_once() in is_errata93() Andrew pointed out that the 'once' variable has a needlessly function-global scope. We can in fact eliminate it completely, via the use of printk_once().
