Subject: [PATCH] sched,kvm: Fix KVM preempt_notifier usage
The preempt-notifier API needs to sleep with the addition of the
static_key, we do however need to hold off preemption while modifying
the preempt notifier list, otherwise a preemption could observe an
inconsistent list state.
There is no reason to have preemption disabled in the caller,
registering a preempt notifier is a purely task local affair.
Therefore move the preempt_disable into the functions and change the
callers to a preemptible context.
Cc: Gleb Natapov <gleb@kernel.org>
Fixes: 1cde2930e154 ("sched/preempt: Add static_key() to preempt_notifiers")

Does the patch below make things work?
This fix could go into the modules tree, as this commit came via Rusty.
Stephen, feel free to add:

pretty much whatever x86 distro you run your build tests on.
Thanks,
Ingo
