[Xen-devel] PATCH: EXPORT_SYMBOL(direct_remap_area_pages)

[Rik v. R. <ri...@re...>]

This (trivial) patch exports the symbol direct_remap_area_pages,
which is needed by the sound modules.  The function declarations
are also moved around so they're in a .h file that's actually
included by the sound core.

Everything still seems to compile.  I will make a kernel RPM with
this fix available tomorrow.
