[PATCH 0/2] riscv, kvm: support KVM_GET_REG_LIST

[Daniel Henrique Barboza]

Hi,

Starting on Linux 6.6 the QEMU RISC-V KVM driver now supports
KMV_GET_REG_LIST. This API will make it simpler for the QEMU KVM driver
to determine whether a KVM reg is present or not.

We'll use this API to fetch ISA_EXT regs during init(). The current
logic will be put in a legacy() helper and will still be used in case
the host KVM module does not support get-reg-list.

Patch 1 contains error handling changes in kvm_riscv_init_multiext_cfg()
where we're using &error_fatal and errno.
