Subject: [patch 0/7] x86: Store irq descriptor in vector array
Date: Sun, 02 Aug 2015 20:38:22 -0000	[thread overview]
Message-ID: <20150802203427.110728870@linutronix.de> (raw)

We store the irq number in the vector array, so we need to lookup the
descriptor at every interrupt. We can avoid that by simply storing the
interrupt descriptor itself in the vector array.

Thanks,

	tglx
