[Xen-devel] [PATCH 0/5] x86: CPU idle management adjustments

["Jan Beulich" <JBeulich@xxxxxxxx>]

The first patch is something I had meant to do forever since the introduction
of mwait-idle. The 2nd patch addresses a latent problem (becoming an active
one with patch 3) in C-state selection when actually entering an idle state.
The 3rd patch is my counterproposal to Brian's intended abuse (as I would
call it) of the mwait-idle driver. The final two patches are ones I've been
carrying for about 5 years now, initially waiting for a response to my
proposed edits to Ross'es patches, and eventually sort of forgotten (but
re-based as needed).

1: x86/cpuidle: switch to uniform meaning of "max_cstate="
2: x86/cpuidle: really use C1 for "urgent" CPUs
3: x86/AMD: make C-state handling independent of Dom0
4: x86: allow limiting the max C-state sub-state
5: tools/libxc: allow controlling the max C-state sub-state
