Subject: [patch V2 18/31] mn10300: Use generic init_task
Date: Thu, 03 May 2012 09:02:56 -0000 [thread overview]
Message-ID: <20120503085035.011270394@linutronix.de> (raw)
In-Reply-To: 20120503083859.991965503@linutronix.de
[-- Attachment #1: mn10300-use-generic-init-task.patch --]
[-- Type: text/plain, Size: 3210 bytes --]
Same code. Use the generic version. The special Makefile treatment is
pointless anyway as init_task.o contains only data which is handled by
the linker script. So no point on being treated like head text.
