Subject: [patch 01/10] powerpc: Move is_32bit_task
Date: Sun, 22 Feb 2009 22:49:58 +1100	[thread overview]
Message-ID: <20090222115331.774772471@samba.org> (raw)
In-Reply-To: 20090222114957.213647384@samba.org

Move is_32bit_task into asm/thread_info.h, that allows us to test for
32/64bit tasks without an ugly CONFIG_PPC64 ifdef.
