MIPS: IP32: Fix hang on shutdown in power button interrupt handler.
The hang was caused by the use of disable_irq() from the interrupt handler itself. Fixed by the use of disable_irq_nosync(). The issue was triggered by: commit 3aa551c9b4c40018f0e261a178e3d25478dc04a9 Author: Thomas Gleixner <tglx@linutronix.de> Date: Mon Mar 23 18:28:15 2009 +0100 genirq: add threaded interrupt handler support Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
