add generic fixmap.h Many architectures provide an asm/fixmap.h which defines support for compile-time 'special' virtual mappings which need to be made before paging_init() has run. This support is also used for early ioremap on x86. Much of this support is identical across the architectures. This patch consolidates all of the common bits into asm-generic/fixmap.h which is intended to be included from arch/*/include/asm/fixmap.h.
