[PATCH 4/7] x86/boot: Switch output functions from command-line flags to conditional compilation
From: Joe Millenbach
Date: Thu Jul 19 2012 - 21:06:15 EST
Changed putstr flagging from parameter to conditional compilation for puts,
debug_putstr, and error_putstr. This allows for space savings since most
configurations won't use this feature.
