[PATCH 7/8] x86 boot: show pfn addresses in hex not decimal in some kernel info printks

[Paul Jackson]

From: Paul Jackson <pj@xxxxxxx>

Page frame numbers (the portion of physical addresses above the low
order page offsets) are displayed in several kernel debug and info
prints in decimal, not hex.  Decimal addresse are unreadable.  Use hex.
