Hi Paolo and Radim,
Here is the first round of KVM/ARM Changes for v4.15. I will follow up
with a second pull request based on tip:irq/core containing the KVM/ARM
side of the GICv4 support.
Changes in this pull requestinclude:
- Optimized arch timer handling for KVM/ARM
- Improvements to the VGIC ITS code and introduction of an ITS reset
ioctl
- Unification of the 32-bit fault injection logic
- More exact external abort matching logic
The following changes since commit 8a5776a5f49812d29fe4b2d0a2d71675c3facf3f:
