Hi Jens,
After merging the block tree, today's linux-next build (powerpc
allnoconfig) failed like this:

Caused by commit
973c4e372c8f ("blk-mq: provide a default queue mapping for PCI device")
include/linux/blk-mq.h does not include all the headers files that it
depends on, and building block/blk-mq-pci.c should depend on CONFIG_BLOCK.
I applied this fix patch (the block/blk-mq-pci.c may not be becessary):
Added, thanks Stephen.
