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.
