Subject: linux-next: boot failure after merge of the tip tree

Hi all,

After merging the tip tree, today's linux-next build (powerpc
pseries_le_defconfig) failed to boot like this:

 Built 1 zonelists, mobility grouping on.  Total pages: 32736
 Policy zone: Normal
 mem auto-init: stack:all(zero), heap alloc:off, heap free:off
 Memory: 2027392K/2097152K available (17984K kernel code, 3328K rwdata, 14784K rodata, 6080K init, 1671K bss, 69760K reserved, 0K cma-reserved)

*crickets*

Bisected to commit

  f4ab23558310 ("slub: Replace cmpxchg_double()")

I have reverted that commit (and the following one) for today.
