Subject: [PATCH -tip] x86: do_IRQ - send EOI for x86-32 on irq without handler
Date: Fri, 3 Apr 2009 22:57:29 +0400 [thread overview]
Message-ID: <20090403185729.GC12273@localhost> (raw)
For X86-32 if IRQ has no handler it remains non-Ack'ed
even if APIC is not requested for being disabled.
Fix it.
