I'm ok with returning 0 from s390's kvm_arch_vcpu_should_kick() until we sort out architecture-specific kicks. Adding kvm_vcpu_wake_up() in [6/6] is the reason why the other patches were included. Compile tested on s390, lightly tested and checked that kvm_*_request() uses are being optimized on x86. Radim Krčmář (6): KVM: fix guest_mode optimization in kvm_make_all_cpus_request() KVM: use kvm_{test,clear}_request instead of {test,clear}_bit KVM: x86: 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 arch/arm/include/asm/kvm_host.h | 2 +- arch/arm64/include/asm/kvm_host.h | 2 +- arch/mips/kvm/emulate.c | 2 +- arch/powerpc/kvm/book3s_pr.c | 2 +- arch/powerpc/kvm/book3s_pr_papr.c | 2 +- arch/powerpc/kvm/booke.c | 4 ++-- arch/powerpc/kvm/powerpc.c | 2 +- arch/s390/kvm/kvm-s390.c | 6 ++---- arch/x86/include/asm/kvm_host.h | 6 +++--- arch/x86/kvm/vmx.c | 2 +- arch/x86/kvm/x86.c | 18 ++++++------------ include/linux/kvm_host.h | 22 +++++++++++++++++----- virt/kvm/kvm_main.c | 7 ++++--- 13 files changed, 41 insertions(+), 36 deletions(-) -- 2.12.0
