[ 23/33] um: Serve io_remap_pfn_range()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
