Hi Paolo,

We have the following KVM RISC-V changes for 6.5:
1) Redirect AMO load/store misaligned traps to KVM guest
2) Trap-n-emulate AIA in-kernel irqchip for KVM guest
3) Svnapot support for KVM Guest

Please pull.

Please note that there is a minor conflict with the RISC-V
tree in the arch/riscv/include/uapi/asm/kvm.h header due to
KVM vector virtualization going through the RISC-V tree.

Regards,
Anup

Thanks for the heads up. I also appreciate that you have fixed the
workflow and the author/committer date are now okay!

Yes, the next branch of KVM RISC-V tree is now part of regular
integration testing in linux-next and I am actively pushing accepted
patches to the next branch much before the actual PR.

Thanks to your suggestions and guidance.
