PCI and other subsystems often use %pR to decode and print memory ranges.
The size of the range is useful to know but hard to read off at a glance,
e.g., 

  BAR 0 [mem 0xfea80000-0xfea9ffff]

Add more user-friendly size information to the %pR format, e.g.,

  BAR 0 [mem 0xfea80000-0xfea9ffff (128 KiB)]

%pR is also used to print I/O port, bus number, and DMA resources, where
the size is not as relevant, so this only applies to IORESOURCE_MEM
resources.

Bjorn Helgaas (2):
  vsprintf: Add %pR human-readable size
  PCI: Include human-readable sizes in resource assignment messages
