Hi Kirill,
Thanks for fixing this!
Could we make the pr_err() a bit more informative, though? It would be
nice to print out how much memory (or which addresses at least) are
being thrown away.
I was also thinking that it would be handy to tell folks how to rectify
the situation. Should we perhaps dump out the runtime status of
X86_FEATURE_LA57?
