Subject[PATCH v3 0/2] change ARM linux memory layout to support 32 CPUs
Date
This patch series change fixmap mapping region to suppport 32 CPUs.
Because the "top_pmd" covers 0xfffe0000 - 0xffffffff(2M). And part
is used by vector table. So I move this region down to 0xffc00000
- 0xffdffff.


I have tested the patches on arma9(2 CPUs) and arma15(16 CPUs) platforms

Changes from v2:
---------------
- Removed two macros: FIX_KMAP_BEGIN and FIX_KMAP_END;
- Unchanged DMA mapping region related documentation;

Changes from v1:
---------------
- changed documentation for ARM linux memory layout.
- moved fixmap mapping region, not just extended.

ARM : fixmap : remove FIX_KMAP_BEGIN and FIX_KMAP_END
ARM : change fixmap mapping region to support 32 CPUs
