Hi Paolo,

We have the following KVM RISC-V changes for 6.4:
1) ONE_REG interface to enable/disable SBI extensions
2) Zbb extension for Guest/VM
3) AIA CSR virtualization
4) Few minor cleanups and fixes

Please pull.

Please note that the Zicboz series has been taken by
Palmer through the RISC-V tree which results in few
minor conflicts in the following files:
arch/riscv/include/asm/hwcap.h
arch/riscv/include/uapi/asm/kvm.h
arch/riscv/kernel/cpu.c
arch/riscv/kernel/cpufeature.c
arch/riscv/kvm/vcpu.c

I am not sure if a shared tag can make things easy
for you or Palmer.

Regards,
Anup
