[GIT PULL] KVM/riscv changes for 6.5

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
