From: Greg Kroah-Hartman
Date: Wed Jun 05 2013 - 16:58:05 EST

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


From: Richard Weinberger <richard@xxxxxx>

commit 4d94d6d030adfdea4837694d293ec6918d133ab2 upstream.

At some places io_remap_pfn_range() is needed.
UML has to serve it like all other archs do.
