Hello x86 maintainers!
I think this series is ready to go. Notes below...

The above patch is really the only thing that has any external visibility
to kernels that have ZSTD disabled. Given the ratios of memory sizes
involved (an extra 64K when we're dealing with 2MB windows) seems
reasonable to me. If that isn't acceptable, it should be trivial to make
it CONFIG-selectable (like we already do with BOOT_HEAP_SIZE).
What do you think? If the non-x86 parts should land first in -mm, I
guess that would be okay, but I think it makes sense for all of this to
go via -tip.
