Subject: [PATCH v3 00/11] x86/init: replace paravirt_enabled() were possible

Boris,

this v3 series addresses a feedback from my last series in trying to
replace or remove paravirt_enabled() as we have been discussing. Some
patches are being spinned once, some others by now 3 times, hence the
v3. Changes per iteration are documented in the commit log on each patch.
I've documented progress on a wiki so far [0] on the crusade to remove
paravirt_enabled(). Seems we just have one more item to go.

Since we're using BIT() for the platform flags I've folded into this
series the patch that adds BIT() for early boot code.

This series has been tested with no issues by 0-day bot.

Any followup on the linker table work or its use through the proof of
concept ports and the new proposed x86 proposed use will depend on this
series, I'll follow through these series using the x86/init prefix unless
told otherwise.

Rusty, a few patches touch touch lguest, although they're trivial it'd still
be good to get your Acked-by or Reviewed-by.

In case anyone needs it these patches are also up on my linux-next
tree on the 20160222-remove-pv-enabled-test-02 branch. They're all
based on linux-next tag next-20160222.
