This is an update to Ian Campbell's work to route timer PPIs to guests
[1].
I attempted to address most of the feedback on v2 of the series. There
are a couple of comments I was unsure about - instances of this are
noted in the individual patches.
Highlights in v3:
* Rebase
* Tested on QEMU with GICv3
* Tested on Xilinx Zynq UltraScale+ with GICv2
While I build-tested with CONFIG_NEW_VGIC=y, I only did a quick runtime
test with the new vGIC and I encountered an ASSERT failure:
Assertion 'irq->hwintid >= VGIC_NR_PRIVATE_IRQS' failed at vgic-mmio.c:96
Because of this, and because there is still some feedback outstanding
from v2, portions of this series may be considered RFC-ish (especially
the last patch "context switch vtimer PPI state").
