Here are some patches that are necessary to get KVM running with the -rt4
patchset.
Cheers,
Jan

This patch removes the stupid "Read locks within the self-held write lock
succeed" behaviour. This is breaking in mm_take_all_locks() since it is quite
common to ensure that a lock is taken with BUG_ON(down_read_trylock(&mm->mmap_sem)).

This patch converts some KVM spin-locks to be of type raw_spinlock_t.

This moves the get_cpu() call down to be called after we wake up the
waiters. Therefore the waitqueue locks can savely be rt mutex.

Good catch. There are some more oddballs in that file, which we missed
when we moved from 26 to 29 - we dropped the rwlocks stuff and that
cleaned up that area.

Thanks a lot.
Unfortunaately, there is still a last one at kernel/smp.c:288
/* Can deadlock when called with interrupts disabled */
WARN_ON_ONCE(irqs_disabled() && !oops_in_progress);
Do we get another fix?
Carsten.

I think I have seen that before. Just remembered that I fixed that
with Avi last year. Patch got dropped in the 26->29 move.

Subject: CFS: enable irqs in fire_sched_in_preempt_notifier
KVM expects the notifier call with irqs enabled. It's necessary due
to a possible IPI call. Make the preempt-rt version behave the same
way as mainline.
