Subject: [PATCH 2/2] MIPS: Mark all but i8259 interrupts as no-probe.
Date: Tue, 29 Jan 2008 11:21:20 +0000	[thread overview]
Message-ID: <20080129112120.GB8665@linux-mips.org> (raw)
In-Reply-To: <20080129112048.GA8665@linux-mips.org>

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