Subject: [PATCH v2 3/4] alpha: Move setup.h out of uapi

Most of the contents of setup.h have no value for userspace
applications. The file was probably moved to uapi accidentally.

Keep the file in uapi to define the alpha-specific COMMAND_LINE_SIZE.
Move all other defines to arch/alpha/include/asm/setup.h.

Suggested-by: Linus Torvalds <torvalds@...ux-foundation.org>
