map_physmem() returns a virtual address which can be used to access a given physical address without involving the cache. unmap_physmem() should be called when the virtual address returned by map_physmem() is no longer needed. This patch adds a stub implementation which simply returns the physical address cast to a uchar * for all architectures except AVR32, which converts the physical address to an uncached virtual mapping. unmap_physmem() is a no-op on all architectures, but if any architecture needs to do such mappings through the TLB, this is the hook where those TLB entries can be invalidated.
