git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into 'kvm-next' KVM/ARM changes for v4.1: - fixes for live migration - irqfd support - kvm-io-bus & vgic rework to enable ioeventfd - page ageing for stage-2 translation - various cleanups
2015-03-26KVM: Redesign kvm_io_bus_ API to pass VCPU structure to the callbacks.Nikolay Nikolaev
This is needed in e.g. ARM vGIC emulation, where the MMIO handling depends on the VCPU that does the access.

2015-03-23KVM: x86: inline kvm_ioapic_handles_vector()Radim Krčmář
An overhead from function call is not appropriate for its size and frequency of execution. Suggested-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Radim Krčmář <rkrcmar@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2015-03-23KVM: x86: call irq notifiers with directed EOIRadim Krčmář
kvm_ioapic_update_eoi() wasn't called if directed EOI was enabled. We need to do that for irq notifiers. (Like with edge interrupts.) Fix it by skipping EOI broadcast only.

2015-03-10KVM: ioapic: Record edge-triggered interrupts delivery statusWincy Van
This patch fixes the bug discussed in https://www.mail-archive.com/kvm@vger.kernel.org/msg109813.html This patch uses a new field named irr_delivered to record the delivery status of edge-triggered interrupts, and clears the delivered interrupts in kvm_get_ioapic. So it has the same effect of commit 0bc830b05c667218d703f2026ec866c49df974fc ("KVM: ioapic: clear IRR for edge-triggered interrupts at delivery") while avoids the bug of Windows guests.

2014-11-21kvm: x86: move ioapic.c and irq_comm.c back to arch/x86/Paolo Bonzini
ia64 does not need them anymore. Ack notifiers become x86-specific too. Suggested-by: Gleb Natapov <gleb@kernel.org> Reviewed-by: Radim Krcmar <rkrcmar@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
