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. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
