Note that LOCKDEP causes the BUG() on line 1159 of drivers/mmc/host/omap.c
to fire too -- exactly the same root cause:  IRQ handler getting called
in a goofy context, because of lockdep.

That's the older OMAP1/OMAP2 driver ... the new highspeed MMC controller
in OMAP3 (handling 8-bit parallel I/O etc, nyet in mainline) doesn't seem
to have the same issue(s).
