[GIT PULL] KVM/riscv changes for 6.3

[Anup Patel]

Hi Paolo,

We have the following KVM RISC-V changes for 6.3:
1) Fix wrong usage of PGDIR_SIZE to check page sizes
2) Fix privilege mode setting in kvm_riscv_vcpu_trap_redirect()
3) Redirect illegal instruction traps to guest
4) SBI PMU support for guest

Please pull.

I will send another PR for 6.3 containing AIA CSR
virtualization after Palmer has sent his first PR for 6.3
so that I can resolve conflicts with arch/riscv changes.
I hope you are okay with this ??

Regards,
Anup
