Yes, but my patch just enable the kernel to support this feature, whether
to use it depens on the device driver.

And this feature has been merged to the kernel for X86 for a long time.
See commit: 5ca72c4f7c412c2002363218901eba5516c476b1
51906e779f2b13b38f8153774c4c7163d412ffd9

Actually, I'm trying to do the test. but it is difficult to do that test,
because it mostly depends on how the device driver to use this feature,
while the ipr driver patch was wrote by another person. also no any reply
from her.
