Subject: [PATCH 16/61] uml: fix processor selection to exclude unsupported processors and features

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

From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@...oo.it>

Makes UML compile on any possible processor choice. The two problems were:

*) x86 code, when 386 is selected, checks at runtime boot_cpuflags, which we do
   not have.
*) 3Dnow support for memcpy() et al. does not compile currently and fixing this
   is not trivial, so simply disable it; with this change, if one selects MK7
   UML compiles (while it did not).
Merged upstream.
