The main fix is patch 2, with the earlier patch setting the stage and
the latter ones simplifying other things at least a little in exchange.

1: allocate emulation cache entries dynamically
2: correct read/write split at page boundaries
3: slightly improve CMPXCHG16B emulation
4: drop redundant access splitting

Oleksii - the first two patches (plus the simple one from v2 that I just
committed) are backporting material, and hence I'd like to ask for a
release ack for at least those two.
