Subject: linux-next: manual merge of the tip tree with the slab tree

Hi all,

Today's linux-next merge of the tip tree got a conflict in mm/slub.c
between commit 964cf35c88f93b4927dbc4e950dfa4d880c7f9d1 ("SLUB: Fix early
boot GFP_DMA allocations") from the slab tree and commit
18fd427debcf37c06917b55295df682fd05fee76 ("slub: add hooks for
kmemcheck") from the tip tree.

I fixed it up (see below) and can carry the fix as necessary.

Btw., this SLAB commit is for this merge window, right?

Yes, it's a fix for SLUB that's going to be part of the next pull
request (probably out today or tomorrow).

OK, thanks Stephen, I'll fix it up in my tree.
