Re: [PATCH v5 16/16] x86/tdx: Add cmdline option to force use of ioremap_host_shared

The connection is quite unfortunate IMHO.
Can't there be an option
that unbreaks drivers *without* opening up security holes by
making BIOS shared?
That would require new low level APIs that distinguish both cases, and a 
tree sweep.
