From 02b30839220fa3ef80a34ed6ee174fa2d9937eac Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 17 Nov 2005 22:43:30 +0000 Subject: [ARM] Fix some corner cases in new mm initialisation Document that the VMALLOC_END address must be aligned to 2MB since it must align with a PGD boundary. Allocate the vectors page early so that the flush_cache_all() later will cause any dirty cache lines in the direct mapping will be safely written back. Move the flush_cache_all() to the second local_flush_cache_tlb() and remove the now redundant first local_flush_cache_tlb().
