I'm seeing my laptop crash/wedge up/something during very early boot - before it can write anything to the console. Nothing in pstore, need to hold down the power button for 6 seconds and reboot.

mm/slab: factor out kmem_cache_node initialization code
It can be reused on other place, so factor out it. Following patch will
use it.
Not sure what the problem is - the logic *looks* ok at first read. The
patch *does* remove a spin_lock_irq() - but I find it difficult to
believe that with it gone, my laptop is able to hit the race condition
the spinlock protects against *every single boot*.
The only other thing I see is that n->free_limit used to be assigned
every time, and now it's only assigned at initial creation.
