Hi Nathan,
thanks for the quick patch.
I can confirm I have no CONFIG_CPUMASK_OFFSTACK set.

[PATCH] x86/paravirt: Avoid setting IF flag, if not necessary
Setting the IF flag can cause an VM exit. So we should avoid touching
the IF flag until absolutely necessary. This patch change the way
the paravirt arch_local_irq_restore() works by checking the previous
flags value and call arch_local_irq_enable() only if the IF flag was
set previously.
On a 32 vCPUs KVM guest running the AIM7 five-sec workload,
the performance increased slightly from 302136.32

[PATCH 00/10] RFC: move logical block size checking to the block core
This patch series aims to move the logical block size checking to the
block code.
This was inspired by missing check for valid logical block size in
virtio-blk which causes the kernel to crash in a weird way later on
when it is invalid.
I added blk_is_valid_logical_block_size which returns true iff the
block size is one of supported sizes.
I added this check to virtio-blk, and also converted
