Hello,

forked from http://marc.info/?l=linux-mm&m=146553910928716&w=2

new_slab()->BUG->die()->exit_signals() can be called from atomic
context: local IRQs disabled in slab_alloc().

I have sent a patch to drop the BUG() from that path today. It
is just too aggressive way to react to a non-critical bug.
