The patch titled
From: Ingo Molnar <mingo@xxxxxxx>
has been added to the -mm tree. Its filename is

See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
------------------------------------------------------
Subject: From: Ingo Molnar <mingo@xxxxxxx>
From: Ingo Molnar <mingo@xxxxxxx>
Subject: sched: cleanup, remove task_t, convert to struct task_struct
cleanup: remove task_t and convert all the uses to struct task_struct. I
introduced it for the scheduler anno and it was a mistake.
Conversion was mostly scripted, the result was reviewed and all
secondary whitespace and style impact (if any) was fixed up by hand.
Depends on the "sched: clean up fallout of recent changes" patch. Goes
to the tail of the scheduler queue.
