From 4a55dd7273c95b4a19fbcf0ae1bbd1cfd09dfc36 Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Thu, 9 Jan 2014 18:43:16 -0600 Subject: [PATCH] kvm: Provide kvm_vcpu_eligible_for_directed_yield() stub Commit 7940876e1330671708186ac3386aa521ffb5c182 ("kvm: make local functions static") broke KVM PPC builds due to removing (rather than moving) the stub version of kvm_vcpu_eligible_for_directed_yield(). This patch reintroduces it.
