[PATCH v3 0/6] Add RISC-V KVM AIA Support

[Yong-Xuan Wang]

This series adds support for KVM AIA in RISC-V architecture.

In order to test these patches, we require Linux with KVM AIA support which can
be found in the qemu_kvm_aia branch at https://github.com/yong-xuan/linux.git
This kernel branch is based on the riscv_aia_v1 branch available at
https://github.com/avpatel/linux.git, and it also includes two additional
patches that fix a KVM AIA bug and reply to the query of KVM_CAP_IRQCHIP.

---
v3:
- fix typo
- tag the linux-header patch as placeholder

v2:
- rebase to riscv-to-apply.next
- update the linux header by the scripts/update-linux-headers.sh

Yong-Xuan Wang (6):
  update-linux-headers: sync-up header with Linux for KVM AIA support
    placeholder
  target/riscv: support the AIA device emulation with KVM enabled
  target/riscv: check the in-kernel irqchip support
  target/riscv: Create an KVM AIA irqchip
  target/riscv: update APLIC and IMSIC to support KVM AIA
  target/riscv: select KVM AIA in riscv virt machine
