[PATCH v2 0/9] KVM: towards maintainable kvm_make_all_cpus_request()

v2 doesn't use kvm_arch_vcpu_should_kick() and hence avoids the big bug
discovered by James. Instead, the last just exposes the synchronization
behavior and prepares it for future merging with
kvm_arch_vcpu_should_kick().

v2 also constains two patches from Andrew that applied without any
changes and a simple optimization for wakeups.

v1: http://www.spinics.net/lists/kvm/msg147898.html

Andrew Jones (2):
KVM: add explicit barrier to kvm_vcpu_kick
KVM: improve arch vcpu request defining

Radim Krčmář (7):
KVM: add kvm_{test,clear}_request to replace {test,clear}_bit
KVM: x86: always use kvm_make_request instead of set_bit
KVM: remove #ifndef CONFIG_S390 around kvm_vcpu_wake_up
KVM: mark requests that do not need a wakeup
KVM: perform a wake_up in kvm_make_all_cpus_request
KVM: return if kvm_vcpu_wake_up() did wake up the VCPU
KVM: mark requests that need synchronization
