Subject: drm/i915: restrict kernel address leak in debugfs

From: Kees Cook <keescook@xxxxxxxxxxxx>

commit 2563a4524febe8f4a98e717e02436d1aaf672aa2 upstream.

Masks kernel address info-leak in object dumps with the %pK suffix,
so they cannot be used to target kernel memory corruption attacks if
the kptr_restrict sysctl is set.
