I looked through the bug report which contains the fix [1], and it seems
that the patch was applied to the Linux 4.9 series and then reverted due
to regression with Skylake [2][3].
Since it works on my Broadwell based system, I'll keep on using it; the
expert opinion is that it cannot be easily backported without more
changes [4].
Thanks,
Aaditya
