In my opinion this is not stable kernel material.
It alone does not solve a particular bug. It's part of a larger effort to decrease usage of the 8254 PIT on modern platforms, which solves a real problem (see "x86: skip PIT initialization on modern chipsets"), but I'd conservatively recommend just leaving these patches out of the stable tree. The problem has existed for a while without a particularly wide impact, and there is a somewhat documented workaround of changing BIOS settings.
Daniel
