[PATCH v2 0/6] RISC-V: KVM: Allow zicbop/bfloat16 exts for guests

[zhouquan]

From: Quan Zhou <zhouquan@xxxxxxxxxxx>

Advertise zicbop/bfloat16 extensions to KVM guest when underlying
host supports it, and add them to get-reg-list test.

---
Change since v1:
- update zicbom/zicboz/zicbop block size registers to depend on the host isa.
- update the reg list filtering in copy_config_reg_indices() to use the host isa.
- add reg list filtering for zicbop.
