Merge tag 'kvm-s390-for-3.15-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux into kvm-master

Here is a fix that aligns the irqfd code changes for 3.15
with the right capability number. irqfd for s390x was
introduced with 3.15-rc1, so this fix should still go into
Linus tree for 3.15
