Paolo, Radim,

Here's a set of update for -rc4. Yet another reset fix, and two subtle
VGIC fixes for issues that can be observed in interesting corner cases.

Note that this is on top of kvmarm-fixes-for-5.3[1], which hasn't been
pulled yet. Hopefully you can pull both at the same time!

Thanks,

	M.

  KVM: arm/arm64: vgic: Reevaluate level sensitive interrupts on enable (2019-08-09 08:07:26 +0100)

----------------------------------------------------------------
KVM/arm fixes for 5.3, take #2

- Fix our system register reset so that we stop writing
  non-sensical values to them, and track which registers
  get reset instead.
- Sync VMCR back from the GIC on WFI so that KVM has an
  exact vue of PMR.
- Reevaluate state of HW-mapped, level triggered interrupts
  on enable.

Pulled both.  Thank you for including the lore link to the 5.3-rc3 pull
request.
