Subject: [PATCH 09/20] x86: set nr_irqs_gsi only in probe_nr_irqs_gsi
Date: Sun, 21 Mar 2010 00:13:10 -0700	[thread overview]
Message-ID: <1269155601-18247-10-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1269155601-18247-1-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.
