Re: [Xen-devel] [PATCH for-4.13] xen/sched: Render sibling/core masks with %pbl to improve 'r' debugkey

For system with large numbers of CPUs, the 'r' debugkey is unwieldy.  Sibling
and core masks are a single block of adjacent bits, so are vastly shorter to
render with %pbl.

Before:
   (XEN) CPU[00] nr_run=0, sort=157, 
sibling=00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000003,
 core=00000000,00000000,00000000,00000000,ffffffff,ffffffff,ffffffff,ffffffff
   (XEN) CPU[01] nr_run=0, sort=13750, 
sibling=00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000003,
 core=00000000,00000000,00000000,00000000,ffffffff,ffffffff,ffffffff,ffffffff
   (XEN) CPU[02] nr_run=0, sort=188, 
sibling=00000000,00000000,00000000,00000000,00000000,00000000,00000000,0000000c,
 core=00000000,00000000,00000000,00000000,ffffffff,ffffffff,ffffffff,ffffffff
   (XEN) CPU[03] nr_run=0, sort=13730, 
sibling=00000000,00000000,00000000,00000000,00000000,00000000,00000000,0000000c,
 core=00000000,00000000,00000000,00000000,ffffffff,ffffffff,ffffffff,ffffffff

After:
   (XEN) CPU[00] nr_run=0, sort=1169, sibling={0-1}, core={0-127}
   (XEN) CPU[01] nr_run=0, sort=2488, sibling={0-1}, core={0-127}
   (XEN) CPU[02] nr_run=0, sort=1210, sibling={2-3}, core={0-127}
   (XEN) CPU[03] nr_run=0, sort=2476, sibling={2-3}, core={0-127}
