Subject: irq: use %*pb[l] to print bitmaps including cpumasks and nodemasks
X-Git-Tag: Ubuntu-5.2.0-15.16~11902^2~61

irq: use %*pb[l] to print bitmaps including cpumasks and nodemasks

printk and friends can now format 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.
