Subject: [PATCH 02/12] x86: set nr_irqs_gsi only in probe_nr_irqs_gsi
Date: Thu, 04 Mar 2010 02:08:49 -0800	[thread overview]
Message-ID: <1267697339-5491-3-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1267697339-5491-1-git-send-email-yinghai@kernel.org>

don't clear that in arch_early_irq_init

probe_nr_irqs_gsi is always called when ioapic is selected in config.

so even for mrst, print out from probe_nr_irqs_gsi is report correct
nr_irqs_gsi

-v2: remove io_apic_irqs assignement, setup_IO_APIC will do that.
