Subject: [PATCH] lguest: prevent VISWS or VOYAGER randconfigs

From: Randy Dunlap <randy.dunlap@...cle.com>

Keep lguest from being enabled on VISWS or VOYAGER configs, just as is
already done for VMI and XEN.  Otherwise randconfigs with VISWS and
LGUEST have this problem:

(and of course, this happens because kconfig does not follow dependencies
when [evil] select is used...)
