This patch set resolves a number of BUG_ON crashes I was hitting on
Hyper-V while booting a kernel with verification options on. With these
I can complete a 3.17.0-rc2 boot on an SMP setup although patches from
"Drivers: hv: vmbus: Miscellaneous cleanup" are needed to resolve other
non-crash issues.
