This looks reasonable to me - thanks for taking the time.

However, I was about to hit send on my PR to Russell for the following series:

https://git.kernel.org/pub/scm/linux/kernel/git/ardb/linux.git/log/?h=arm-vfp-softirq-fixes

which moves all of the VFP processing to C, and so this is going to
conflict at the very least, but also provide a cleaner base for patch
#2 in this series.

Also, aren't there a few other places in the VFP code where BH are
disabled and enabled again? Do those need the same treatment?

Thanks,
Ard.
