Quick sanity checks in cpu_idle() show:

i8259_mask         = 0x00002c41 or 0x00002ce7 (and more?)
spl_mask           = 0xffff2c5d (== spl_masks[_SPL_CLOCK])
current_mask       = 0x0000d3ba (== all unestablished irqs are disabled)
disabled_mask      = 0x00000000
current_spl_level  = 0
current_intr_depth = 0

So at least spl_mask seems wrong.

dump_spl_masks() shows:

(btw spl_mask[foo] should be spl_masks[foo], it seems)
