Let me see if there is a way to distinguish between 4. and 5. below:
CPU category X86_BUG_MMIO_STALE_DATA X86_BUG_MMIO_UNKNOWN
- Known affected (in cpu list) 1 0
- CPUs with HW immunity (MMIO_NO=1) 0 0
- Other vendors 0 0
- Older Intel CPUs 0 1
- Not affected current CPUs (but MMIO_NO=0) 0 ?
Not affected current CPUs should be arch_cap_mmio_immune() == true, no?
