Subject: [PATCH] (20/22) task_thread_info - part 3/4
Date: Thu, 25 Aug 2005 06:25:21 +0100 [thread overview]
Message-ID: <E1E8AEr-0005ep-Q8@parcelfarce.linux.theplanet.co.uk> (raw)
a) added embedded thread_info [m68k processor.h]
b) added missing symbols in asm-offsets.c
c) task_thread_info() and freinds in asm-m68k/thread_info.h
d) made m68k thread_info.h included by m68k processor.h, not the
other way round.
