4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jason A. Donenfeld <ja...@zx2c4.com>
commit 530ba6c7cb3c22435a4d26de47037bb6f86a5329 upstream.
Recent libcs have gotten a bit more strict, so we actually need to
include the right headers and use the right types. This enables UML to
compile again.
