Subject: mm: debug: make bad_range() output more usable and readable
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=613813e8985bb76bd27937bfa54faf9e9be95a52;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mm: debug: make bad_range() output more usable and readable

Nobody outputs memory addresses in decimal.  PFNs are essentially
addresses, and they're gibberish in decimal.  Output them in hex.

Also, add the nid and zone name to give a little more context to the
message.
