[PATCH] x86: Fix overlap of i386 CPU_ENTRY_AREA with FIX_BTMAP

oduced, as the fixmap has classically been preceded by the pkmap or vmalloc areas, neither of which is used until early_ioremap is out of the picture. Relocate CPU_ENTRY_AREA to below FIX_BTMAP, not just below the permanent fixmap area. Signed-off-by: William Grant --- This fixes a triple fault durin
