Subject: [patch 16/76] MIPS: Mark all but i8259 interrupts as no-probe.

-stable review patch. If anyone has any objections, please let us know.
---------------------

From: Ralf Baechle <[email protected]>

Use set_irq_noprobe() to mark all MIPS interrupts as non-probe. Override that
default for i8259 interrupts.
