[RFC][PATCH 0/4] sched_clock vs TSC wreckage

[Peter Zijlstra]

A few weeks ago Nicolas reported some impressive TSC wreckage on his i7-3820
running on an AsusTek Rampage IV Gene board [*].

These are a few patches that should hopefully allow us to do better in the face
of such 'creativity'.

[*] to be fair, Asus did in fact release a BIOS update that fixes this issue.
