Subject: [Patch V3 27/37] x86, irq, mpparse: use common irqdomain map interface to program IOAPIC pins
Date: Tue, 27 May 2014 16:08:02 +0800	[thread overview]
Message-ID: <1401178092-1228-28-git-send-email-jiang.liu@linux.intel.com> (raw)
In-Reply-To: <1401178092-1228-1-git-send-email-jiang.liu@linux.intel.com>

Refine mpparse to use common irqdomain map interface to program IOAPIC pins,
so we can unify the callsite to progam IOAPIC pins.
