[PATCH v6 00/16] x86: remove paravirt_enabled()

[Luis R. Rodriguez]

This v6 series addresses:

 - addresses the __init on xen_dom0_set_legacy_features()
   as Juergen asked, the reason the size impact doesn't
   changea as per 0-day is 0-day uses x86 tinyconfig but
   the gains should be there

 - I looked for stragglers on Reivewed-by / Acked-by tags,
   I could not find anything else missing. If I left your
   tag out it means the patch has changed since your last
   review and your blessings would be good to have. Seems
   the only ones missing were Rusty's for lguest stuff and
   Juergen Acked-by for the patch "x86/paravirt: remove
   paravirt_enabled()"

 - Folds the X86_SUBARCH_INTEL_MID and X86_SUBARCH_CE4100
   new uses of the quirks. As such it also adjusts the
   commit log for the X86_SUBARCH_INTEL_MID patch to
   account for the vmlinux size impact as per 0-day on
   tinyconfig.

This has been all tested by 0-day. This series is available
