ARM: 9467/1: mm: Don't use %pK through printk
[ Upstream commit 012ea376a5948b025f260aa45d2a6ec5d96674ea ]
Restricted pointers ("%pK") were never meant to be used
through printk(). They can acquire sleeping locks in atomic contexts.
Switch to %px over the more secure %p as this usage is a debugging aid,
gated behind CONFIG_DEBUG_VIRTUAL and used by WARN().
