Benjamin Herrenschmidt e4ee69c8c1 [PATCH] ppc32: Bump PMU interrupt priority ... The Power Management Unit on PowerMacs is very sensitive to timeouts during async message exchanges. It uses rather crude protocol based on a shift register with an interrupt and is almost continuously exchanging messages with the host CPU on laptops. This patch adds a routine to the open_pic driver to be able to select a PMU driver so that it bumps it's interrupt priority to above the normal level. This will allow PMU interrupts to occur while another interrupt is pending, and thus reduce the risk of machine beeing abruptly shutdown by the PMU due to a timeout in PMU communication caused by excessive interrupt latency. The problem is very rare, and usually just doesn't happen, but it is still useful to make things even more robust.
