From f08252623c7981f5cea70e4fab4983a94fc52212 Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Tue, 27 May 2008 21:19:16 +0100 Subject: [PATCH] x86: I/O APIC: fix the name of the through-8259A handler When the through-8259A mode is used for the timer, the call to set_irq_handler() will register a NULL handler name, resulting in "IO-APIC-" reported. Fix by calling ioapic_register_intr() as done for all the other I/O APIC interrupts. The 64-bit variation calls set_irq_chip_and_handler_name() here needlessly and should get fixed with the upcoming merge. Signed-off-by: Maciej W.
