Paolo,
Here's the main set of KVM/arm updates for Linux 5.7. Two items on the menu
this time:
- Support for GICv4.1, which allows for the direct injection of more
interrupt classes than GICv4.0, and a much more sensible set of
interactions with the hypervisor.
- Removal of the 32bit host support. It has been a fun ride, but with a
general lack of interest as well as the 32bit Linux/ARM port being in "odd
fixes" mode, there is little point in pretending that we care (100% of the
activity is in the arm64 camp). This will, over time, result in cleaner
code (less pointless abstractions) and be easier for arm64 to gain new
features.
Please note that pulling from this tag will drag the GICv4.1 dependencies,
as they are part a shared branch between the irqchip and kvmarm trees. These
patches are already in Linus' tree as of this morning.
Please pull,
M.
The following changes since commit 009384b38034111bf2c0c7bfb2740f5bd45c176c:
