Also please notice that intr enable/disable happens in the wrong way as it is done via the MD (x86 specific likely) interface. This is wrong for 2 reasons: 1) There may be some codepaths leading to explicit preemption 2) It should really use an MI interface The right way to do this should be via spinlock_enter().
