Hi,

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
