linux-yocto: Work around PAT issue on qemux86
We have an issue with PAT handling on older processes with limited PAT bits, see the patch description for the full problem. This replaces the runqemu workaround with a kernel patch until we can get the kernel trees sorted out and discuss a proper fix with upstream. It should be safe everywhere so is applied unconditionally. (From OE-Core rev: e00f0794a535c8e68ae1c87c8b01dd65645d570b) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
