[PATCH] ARC: Use 40-bit physical page mask for PAE

32-bit PAGE_MASK can not be used as a mask for physical addresses when PAE is enabled. PHYSICAL_PAGE_MASK must be used for physical addresses instead of PAGE_MASK. Signed-off-by: Vladimir Isaev --- arch/arc/include/asm/pgtable.h | 12 +++- arch/arc/include/uapi/asm/page.h | 7

[PATCH] ARC: Use max_high_pfn as a HIGHMEM zone border

Commit 4af22ded0ecf ("arc: fix memory initialization for systems with two memory banks") fixed highmem, but not for PAE case when highmem is actually bigger than lowmem. Signed-off-by: Vladimir Isaev Cc: Mike Rapoport --- arch/arc/mm/init.c | 2 +- 1 file changed, 1 insertion(+),

[PATCH v2] ARC: Use max_high_pfn as a HIGHMEM zone border
