Sounds like I need to school that "suggestor" about clearcpuid. :)
For example, when doing this:
1625c833db93 ("x86/cpu: Allow feature bit names from /proc/cpuinfo in clearcpuid=")
I even managed to prevent the kernel from booting. So clearcpuid= is
definitely not for general consumption.
So as said, please remove it from your whole patchset's text.
Thx.
