Hi Steven,
This patch should fix the hang you were seeing in 24-rc2-rt1-pre9 with "#8"
applied. I meant to bring this required -rt specific change up when we spoke
on IRC earlier, but it slipped through the cracks. :( Sorry 'bout that.
Regards,
-Greg

RT: convert cpupri spinlock_t to raw_spinlock_t
We recently started preparing some of the scheduler changes for upstream
merginging. Part of this work involved changing the original raw_spinlock
used in cpupri to a spinlock since this is proper use for a mainline change.
However, in order to continue to use this patch back in -rt, we need to
restore the lock back to raw or the kernel will hang during bootup.
So this patch does the conversion, but should not go upstream with the rest
of the scheduler enhancements until the -rt spinlock work is also merged.
