The latest KVM in Linux-6.5 has support for:
1) Svnapot ISA extension support
2) AIA in-kernel irqchip support

This series adds corresponding changes in KVMTOOL to use the above
mentioned features for Guest/VM.

These patches can also be found in the riscv_aia_v2 branch at:
https://github.com/avpatel/kvmtool.git

Changes since v1:
 - Rebased on commit 9cb1b46cb765972326a46bdba867d441a842af56
 - Updated PATCH1 to sync header with released Linux-6.5

Anup Patel (6):
  Sync-up header with Linux-6.5 for KVM RISC-V
  riscv: Add Svnapot extension support
  riscv: Make irqchip support pluggable
  riscv: Add IRQFD support for in-kernel AIA irqchip
  riscv: Use AIA in-kernel irqchip whenever KVM RISC-V supports
  riscv: Fix guest/init linkage for multilib toolchain

There are a bunch of open review comments from Drew that need to be
addressed in a subsequent version.
