Title:
rtsx_usb_ms: system load immediately climbs, and stays above 1.00

Bug description:
I'm running 64 bit ubuntu 14.10 on an Asus N550JK-DB74T laptop. When I
startup Ubuntu the system load climbs to 1.00 within a minute, and it never
goes below 1.00 again, despite my processor being idle. This behavior occurs
in all the newer kernels I installed from
http://kernel.ubuntu.com/~kernel-ppa/mainline/ but when I installed the kernel
from ubuntu 14.04, as well when I ran the ubuntu 14.04 from a usb the load
average behaved normally, so the bug must have started in either kernel 3.15 or
3.16.
When I posted this to ubuntu forums, a very helpful person able to point me
to this bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=765717
and to this submitted patch https://lkml.org/lkml/2014/11/5/905 . When I
applied that patch to kernel 3.16 my issue was solved. However it doesn't seem
that this patch has been has been merged into the kernel, even though it was
submitted well in time for the 3.19 merge window. I was advised to file this
bug report in the meantime.
