[patch 25/59] Fix UML on non-standard VM split hosts

[Chris Wright <chrisw@sous-sol.org>]

-stable review patch.  If anyone has any objections, please let us know.
------------------

From: Jeff Dike <jdike@addtoit.com>

This fixes UML on hosts with non-standard VM splits.  We had changed
the config variable that controls UML behavior on such hosts, but not
propogated the change everywhere.  In particular, the values of
STUB_CODE and STUB_DATA relied on the old variable.

I also reformatted the HOST_VMSPLIT_3G help to make it more standard.

Spotted by uml@flonatel.org.
