Linus Torvalds 024b246ed2 alpha: move include/asm-alpha to arch/alpha/include/asm 
Sam Ravnborg did the build-test that the direct header file move works,
I'm just committing it.

This is a pure move:

	mkdir arch/alpha/include
	git mv include/asm-alpha arch/alpha/include/asm

with no other changes.
