[patch 35/49] uml: memcpy export needs to follow host declaration

[Greg KH]

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

------------------

From: Jeff Dike <jdike@xxxxxxxxxxx>

commit 8bfd04b974689f700bbd053ad6e66b0a95fb80c9 upstream

x86_64 defines either memcpy or __memcpy depending on the gcc version, and
it looks like UML needs to follow that in its exporting.
