Subject: [PATCH v3 00/15] x86/paravirt, xen: several cleanups
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.
Some Xen related cleanups:
- move some pv-only code from CONFIG_XEN to CONFIG_XEN_PV
- use CONFIG_XEN_PVHVM in Makefile instead of #ifdef around a complete source
- add SPDX identifier where missing
A pvops kernel without XEN_PV being configured is about 2.5% smaller
with this series applied.
Changes in V3:
- merged with the Xen cleanup series which is a prerequisite for the
pv cleanup
- fix build errors on ARM
- let VSMP select PARAVIRT_XXL, put all irq_ops under PARAVIRT_XXL
Changes in V2:
- patch 4: shorten pv_ops sub-structure names (Jan Beulich)
- patch 11: new patch
Juergen Gross (15):
xen: move pv irq related functions under CONFIG_XEN_PV umbrella
xen: move pv specific parts of arch/x86/xen/mmu.c to mmu_pv.c
xen: link platform-pci-unplug.o only if CONFIG_XEN_PVHVM
xen: add SPDX identifier in arch/x86/xen files
