Hi Paolo,

We have the following KVM RISC-V changes for 6.13:
1) Accelerate KVM RISC-V when running as a guest
2) Perf support to collect KVM guest statistics from host side

In addition, the pointer masking support (Ssnpm and
Smnpm) for KVM guest is going through the RISC-V tree.

I also have Svade and Svadu support for host and guest
in my queue which I will send in the second week of the
merge window to avoid conflict with the RISC-V tree.

Please pull.

Regards,
Anup
