[h8300] move include/asm-h8300 to arch/h8300/include/asm
Done as a script (well, a single "git mv" actually) on request from Yoshinori Sato as a way to avoid a huge diff. Requested-by: Yoshinori Sato <ysato@users.sourceforge.jp> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
