[Xen-devel] [PATCH v9 00/10] gic and vgic fixes and improvements

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

Hi all,
this patch series is a collection of three previously sent patch series
to fix bugs in the gic/vgic and implement irq migration on arm.
They have been grouped together under Ian's suggestion.

The last versions of the series, sent separately, were:
<alpine.DEB.2.02.1407031546180.11722@xxxxxxxxxxxxxxxxxxxxxxx>
<alpine.DEB.2.02.1406131216260.13771@xxxxxxxxxxxxxxxxxxxxxxx>
<alpine.DEB.2.02.1406241906040.19982@xxxxxxxxxxxxxxxxxxxxxxx>


Changes in v9:
- move vgic_get_target_vcpu declaration to vgic.h;
- move _vgic_get_target_vcpu to vgic-v2.c and name it
vgic_v2_get_target_vcpu;
- introduce get_target_vcpu to vgic_ops;
- simplify the code to deal with inflight irqs while migrating irqs;
- move arch_move_irqs declaration to irq.h;
- use an arch hook to remove workaround to inject evtchn_irq on irq
enable;
- add explicit flags parameter to vgic_lock_rank and vgic_unlock_rank;
- do not rename IRQF_SHARED to IRQ_SHARED.
