  I'm not sure off the top of my head if we have a good one for that or
if it's worth the trouble.

I expect that would be easy on 64-bit (no way the kernel needs all the
PGD entries from 256..511) but hard for 32-bit (where kernel address
space is in critically short supply on any machine with >1GB RAM).

No LASS on 32 bits...
