Subject: [Patch Part2 v4 31/33] x86: Cleanup irq_domain ops
Date: Tue, 20 Jan 2015 13:51:51 +0800 [thread overview]
Message-ID: <1421733113-15704-32-git-send-email-jiang.liu@linux.intel.com> (raw)
In-Reply-To: <1421733113-15704-1-git-send-email-jiang.liu@linux.intel.com>
From: Thomas Gleixner <tglx@linutronix.de>
We have 3 identical copies of the ioapic domain ops for acpi, mpparse,
and sfi. Have a global one in the io_apic code and be done with it.
To avoid include hell in io_apic.h, create a private irqdomain header
and include the generic irqdomain header from there.
