Series mm/kmemleak: use %pK to display kernel pointers in backtrace |

Commit Message

  Currently, %p is used to display kernel pointers in backtrace which result
in a hashed value that is not usable to correlate the address for debug.
Use %pK which will respect the kptr_restrict configuration value and thus
allow to extract meaningful information from the backtrace.
