From: Henrik Kretzschmar Date: Tue, 22 Feb 2011 14:38:06 +0000 (+0100) Subject: x86: Add dummy functions for compiling without IOAPIC X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=7d0f1926131cf79aa5998d463bf1582156e7b41e;p=deliverable%2Flinux.git x86: Add dummy functions for compiling without IOAPIC This patch adds IOAPIC dummy functions for compilation with local APIC, but without IOAPIC. The local variable ioapic_entries in enable_IR_x2apic() does not need initialization anymore, since the dummy returns NULL.
