Subject: [patch V2 00/31] init_task: Use a generic init_task variant
Date: Thu, 03 May 2012 09:02:46 -0000
Message-ID: <20120503083859.991965503@linutronix.de> (raw)

All architectures do roughly the same to initialize init_task. The
only architecture which deviates is ia64 as it allocates task_struct
and thread_info together.

Move the common code to init/init_task.c and remove all the redundant
copies.

Difference to V1:
	- FRV updates
	- left IA64 alone
	- Score/Sparc corrections
	- Picked up Acked-bys

Thanks,

        tglx
