Subject: [PATCH 2/7] ALPHA: build fixes - force architecture, eliminate wastage

Files:

arch/alpha/kernel/sys_titan.c

	Request EV67 since no TITAN-based machine is any less, or see errors.

include/asm-alpha/compiler.h

	Request EV56 so we're sure to get what we want, or see errors.

include/asm-alpha/module.h

	Stop all the wasted/worthless "got" messages.
