per-cpu alloc debug patch

I think bisecting again would be a poor use of your time unless somebody knows
a smarter way to do it (I don't).

I suspect amdgpu might be an innocent bystander.  I don't have any good ideas,
so here's a lame one:

  - Apply this patch.
  - Figure out how to turn on pr_debug (see include/linux/printk.h and compare
with your config -- you might need to enable CONFIG_DYNAMIC_DEBUG and and then
figure out what boot parameter enables the output).  This is to turn on the
debug in module_load().  Actually, the simpler way is to change those
pr_debug() calls to pr_info().
  - Collect the dmesg log (probably large).
