Subject: [PATCH 04/32] bitmap: use %*pb[l] to print bitmaps including cpumasks and nodemasks

printk and friends can now formap bitmaps using '%*pb[l]'.  cpumask
and nodemask also provide cpumask_pr_args() and nodemask_pr_args()
respectively which can be used to generate the two printf arguments
necessary to format the specified cpu/nodemask.

This patch is dependent on the following two patches.

 lib/vsprintf: implement bitmap printing through '%*pb[l]'
 cpumask, nodemask: implement cpumask/nodemask_pr_args()

Please wait till the forementioned patches are merged to mainline
before applying to subsystem trees.
