From ab66a50e31deb48b0444c248e67e5aa3217efda5 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 15 Feb 2006 01:18:19 -0800 Subject: [PATCH] [SPARC64]: Two IRQ handling fixes. On SUN4V, force IRQ state to idle in enable_irq(). However, I'm still not sure this is %100 correct. Call add_interrupt_randomness() on SUN4V too. Signed-off-by: David S.
