From 9caebec7b8093574fca5a334a1939530872d75e3 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sat, 12 May 2007 17:56:11 +0200 Subject: [AVR32] optimize pagefault path Avoid the costly notifier list in the pagefault path and call the kprobes code directly. The same change went into the 2.6.22 cycle for powerpc, 2s390 and sparc64 already.
