Subject: drm/i915: Print memory region info during probe
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2ab1fe53e298fd2ca6491c73a8d306cc042cd2f0;p=linux.git

drm/i915: Print memory region info during probe

Dump the details about every memory region into dmesg at probe time.
Avoids having to dig those out from random places when debugging stuff.
