From 6730c3c14421b7c924d06e31bb66e0adad225547 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Wed, 9 Nov 2005 14:56:00 -0800 Subject: [PATCH] Fix AGP compile on non-x86 architectures AGP shouldn't use "global_flush_tlb()" to flush the AGP mappings, that i spurely an x86'ism. The proper AGP mapping flusher that should be used is "flush_agp_mappings()", which on x86 obviously happens to do a global TLB flush. This makes AGP (or at least the config _I_ happen to use) compile again on ppc64.
