[Xen-devel] PATCH: EXPORT_SYMBOL(direct_remap_area_pages)
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.
