This just shows this dreaded VMSPLIT config was a bad idea in the first
place. There was a reason we didn't have it for such a long time (too
many users get it wrong) and such occurrences just show again that this
is still true.

IMHO it would be best to just remove that option again and require
users who really want to change this to patch their kernels again.

At the very least it should be probably made dependent on CONFIG_EMBEDDED.

Mark VMSPLIT EMBEDDED

Too many users get it wrong.
