The patch titled
m32r: convert cpumask api
has been removed from the -mm tree. Its filename was
m32r-convert-cpumask-api.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: m32r: convert cpumask api
From: KOSAKI Motohiro <kosaki.motohiro@xxxxxxxxxxxxxx>
We plan to remove cpus_xx() old cpumask APIs later. Also, we plan to
change mm_cpu_mask() implementation, allocate only nr_cpu_ids, thus
*mm_cpu_mask() is dangerous operation.
Then, this patch convert them.
