From: Dmitri Vorobiev Date: Tue, 1 Apr 2008 23:58:38 +0000 (+0400) Subject: [MIPS] unexport null_perf_irq() and make it static X-Git-Tag: v2.6.26-rc1~700^2~17 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=46684734dd6a55af09c3fe799af7d74cb938684c;p=linux-2.6 [MIPS] unexport null_perf_irq() and make it static This patch unexports the null_perf_irq() symbol, and simultaneously makes this function static.
