[PATCH 0/1] Avoid NULL pointer deref in debug stacktrace

[Simon Richter]

Hi,

I stumbled across this potential NULL pointer dereference today,
stack_table and stack_hash_mask in lib/stackdepot.c are both zero before
initialization.

This seems to fix it, but changes core kernel config from a module, so it
may not be ideal.

If there is an init call that can be made instead, that is probably a
better solution, but I'm already three layers into debugging :]
