Hi Ingo,
here's a little stuff which got done baking. More specifically, the use
of this new MWAITX insn on AMD as a more power-optimal delay function.
Patch 3's commit message has details as to how exactly it was measured.
The power measurement interface will be part of fam15h_power soon too.
Please queue for 4.3.
Btw, patch 3 uses rdtsc_ordered() which is in tip/x86/asm... Patch 1
goes to tip/x86/microcode, of course.
Thanks.

x86/microcode: Use kmemdup() rather than duplicating its
implementation

x86/asm: Add MONITORX/MWAITX insns support
x86/asm: Introduce an MWAITX-based delay with a configurable timer
