Ben,
the following patch series is from preempt-rt. It converts the locks
which need to be real spinlocks in -rt to raw_spinlocks.
There is no behaviourial change for !RT kernels because spinlocks and
raw_spinlocks are the same on !RT. So for mainline this is a pure
annotation while having it in mainline takes the burden of keeping up
with the code changes from the RT patch set.
Please consider to merge into .34.
Thanks,
tglx
