Hi Paolo and Radim,
Here are the KVM/ARM Changes for v4.9. They include:
- Various cleanups and removal of redundant code
- Two important fixes for not using an in-kernel irqchip
- A bit of optimizations
- Handle SError exceptions and present them to guests if appropriate
- Proxying of GICV access at EL2 if guest mappings are unsafe
- GICv3 on AArch32 on ARMv8
- Preparations for GICv3 save/restore, including ABI docs
The following changes since commit 9ac7e3e815060efdc86b6d12448200e3c3597e01:
KVM: nVMX: expose INS/OUTS information support (2016-09-07 19:34:30 +0200)
