[Xen-devel] [PATCH] x86/pt: fix binding of MSIX entries already unmasked

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

Hello,

The following two patches fix an issue where a MSIX interrupt bound to
a guest when the MSIX entry is already unmasked would be left masked,
and thus the guest would not receive any interrupts from the device.

The following two patches fix this by adding a new flag to the gflags
field used in XEN_DOMCTL_bind_pt_irq so that the caller can request
the interrupt to be unmasked once bound.

Thanks, Roger.
