Subject: [patch V2 13/31] hexagon: Use generic idle_task
Date: Thu, 03 May 2012 09:02:54 -0000
Message-ID: <20120503085034.692078846@linutronix.de> (raw)
In-Reply-To: <20120503083859.991965503@linutronix.de>


[-- Attachment #0: hexagon-use-generic-idle-task.patch --]
[-- Type: text/plain, Size: 3834 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.
