For some reason this makes my Ux500 system arbitrarily hang,
especially during boot. Bisected down to this commit.
Since the entire changeset is removing the notifications
altogether I can't just revert it.
Disabling CONFIG_CPU_IDLE removes the problem.
Tried registering a stub driver (I just #if 0 all the code in
drivers/cpuidle/cpuidle-ux500.c) it still crashes.
That makes me think something inside the cpuidle subsystem
is locking up after this, but my other idea is that the timer
may be involved in some way, like this is stressing the timer
in some new yet untested way.
Has anyone else seen problems with this or is it only
I'm looking closer at it but feel a bit clueless...
