[PATCH 4.9 10/29] tools include: Add UINT_MAX def to kernel.h

From: Greg Kroah-Hartman
Date: Mon Jun 04 2018 - 02:59:04 EST

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


From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

commit eaa75b5117d52adf1efd3c6c3fb4bd8f97de648b upstream.

The kernel has it and some files we got from there would require us
including the userland header for that, so add it conditionally.
