From f880ec78fabebc58180778d223600e9be7b48502 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 23 Feb 2011 13:07:54 +0100 Subject: [PATCH] x86: ioapic: Use new setup function in pre_init_apic_IRQ0() Remove the duplicated code and call the function. It does not matter whether we allocated the cfg before calling setup_local_APIC() and we can set the irq chip and handler after that as well.
