MN10300 arch headers and place them instead in the same directories as contain the .c files for the processor and unit implementations. This permits the symlinks include/asm/proc and include/asm/unit to be dispensed with. This does, however, require that #include <asm/proc/xxx.h> be converted to #include <proc/xxx.h> and similarly for asm/unit -> unit. Signed-off-by: David Howells <dhowells@redhat.com>
