From 3ee62d365b519c0c18c774049efcde84fe51c60c Mon Sep 17 00:00:00 2001 From: Milton Miller Date: Tue, 10 May 2011 19:30:36 +0000 Subject: powerpc: Add virq_is_host to reduce virq_to_host usage Some irq_host implementations are using virq_to_host to check if they are the irq_host for a virtual irq. To allow us to make space versus time tradeoffs, replace this usage with an assertive virq_is_host that confirms or denies the irq is associated with the given irq_host.
