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.
