This series removes some no longer needed stuff from paravirt
infrastructure and puts large quantities of paravirt ops under a new
config option PARAVIRT_XXL which is selected by XEN_PV only.
A pvops kernel without XEN_PV being configured is about 2.5% smaller
with this series applied.
tip commit 5800dc5c19f34e6e03b5adab1282535cb102fafd ("x86/paravirt:
Fix spectre-v2 mitigations for paravirt guests") is a prerequisite
for this series.
The last 4 patches of this series require my Xen cleanup series
https://lore.kernel.org/lkml/20180717120113.12756-1-jgross@suse.com/
which hides more Xen PV-only code behind CONFIG_XEN_PV.
