[PATCH 4.9 52/83] binder: Replace "%p" with "%pK" for stable

From: Greg Kroah-Hartman
Date: Sun Jun 09 2019 - 13:20:23 EST


From: Ben Hutchings <ben.hutchings@xxxxxxxxxxxxxxx>

This was done as part of upstream commits fdfb4a99b6ab "8inder:
separate binder allocator structure from binder proc", 19c987241ca1
"binder: separate out binder_alloc functions", and 7a4408c6bd3e
"binder: make sure accesses to proc/thread are safe". However, those
commits made lots of other changes that are not suitable for stable.
