This patch adds support for early_ioremap and early_memremap, based on the existing mechanism in x86. Up to 7 regions of up to 128KB each can be temporarily mapped in before paging_init, regardless of later highmem status.
New for this version: - Addressed feedback on v2 - *cough* corrected early_memremap() to use MT_WRITEALLOC instead of MT_UNCACHED.
