The later isn't as simple :) I believe the bulk of such code in

Yeah but it would be useful for hash I suppose if one really wants to
boot with nobats. Though at least on hash most of the time we have ways
to recover by mean of MSR:RI being cleared, which your TLB miss code
doesn't check...

Anyhow, the config option is still valid as if enabled
it will pin several DTLB's too. Scott had some concerns about removing
the config option completely so this was the next best thing.

Well, if you want to pin at least one entry, then just remove the #if
completely but don't leave a #if 1 :-)
