[PATCH v2 11/11] KVM: riscv: selftests: Add get-reg-list test

Haibo Xu
2023-05-25T07:37:25Z

get-reg-list test is used to check for KVM registers regressions
during VM migration which happens when destination host kernel
missing registers that the source host kernel has. The blessed
list registers was created by running on v6.4-rc2.
