[PATCH for-4.14 0/2] x86/passthrough: fixes for PVH dom0 edge triggered interrupts

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

Hello,

Small series with two bugfixes to correctly handle edge triggered
interrupts on PVH dom0.

for-4.14 reasoning: fixes are isolated to PVH dom0 specific passthrough
code (IDENTITY_GSI kind of bindings), and hence shouldn't affect
passthrough to HVM domUs. Without these fixes the RTC timer won't work
correctly on a PVH dom0 because it's edge triggered (GSI 8).

Roger Pau Monne (2):
  x86/passthrough: do not assert edge triggered GSIs for PVH dom0
  x86/passthrough: introduce a flag for GSIs not requiring an EOI or
    unmask
