Message

This series adds initial support for testing KVM RISC-V 64-bit using
kernel selftests framework. The PATCH1 & PATCH2 of this series does
some ground work in KVM RISC-V to implement RISC-V support in the KVM
selftests whereas remaining patches does required changes in the KVM
selftests.

These patches can be found in riscv_kvm_selftests_v3 branch at:
https://github.com/avpatel/linux.git

Changes since v2:
 - Rebased series on Linux-5.16-rc6
 - Renamed kvm_riscv_stage2_gpa_size() to kvm_riscv_stage2_gpa_bits()
   in PATCH2

Changes since v1:
 - Renamed kvm_sbi_ext_expevend_handler() to kvm_sbi_ext_forward_handler()
   in PATCH1
 - Renamed KVM_CAP_RISCV_VM_GPA_SIZE to KVM_CAP_VM_GPA_BITS in PATCH2
   and PATCH4

Anup Patel (4):
  RISC-V: KVM: Forward SBI experimental and vendor extensions
  RISC-V: KVM: Add VM capability to allow userspace get GPA bits
  KVM: selftests: Add EXTRA_CFLAGS in top-level Makefile
  KVM: selftests: Add initial support for RISC-V 64-bit

This is actually v3 series so please ignore the "PATCH v4" subject prefix.
