SVN rev 217304 on 2011-01-12 13:16:35Z by jchandra
The message ring interrupt needs to be enabled for all cpus, not just
the ones which run the message ring handler.
Some bits of the interrupt mask are part of the status register which is
saved with the process context, and these bits are initialized from the
cpu on which the process is created. This means that all the processes
should have the same value for these interrupt mask bits, so that the
interrupt mask remains the same regardless of what thread is scheduled
on the cpu.
