-The generic rwsem implementation of down_read() and down_write() does not

-save and restore interrupt state.  This causes powerdomain code to

-inadvertently enable interrupts early in the boot process, causing

-init/main.c to complain.   This patch converts powerdomain locking to

-r-w spinlocks instead.

-

-I'm also curious to know if this fixes the BeagleBoard boot problem.
