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 x86/paravirt: make paravirt_patch_call() and paravirt_patch_jmp() static x86/paravirt: remove clobbers parameter from paravirt patch functions x86/paravirt: remove clobbers from struct paravirt_patch_site x86/paravirt: use a single ops structure x86/paravirt: remove unused paravirt bits x86/paravirt: introduce new config option PARAVIRT_XXL x86/paravirt: move items in pv_info under PARAVIRT_XXL umbrella x86/paravirt: move the Xen-only pv_cpu_ops under the PARAVIRT_XXL umbrella x86/paravirt: move the pv_irq_ops under the PARAVIRT_XXL umbrella x86/paravirt: move the Xen-only pv_mmu_ops under the PARAVIRT_XXL umbrella x86/paravirt: remove unneeded mmu related paravirt ops bits arch/arm/include/asm/paravirt.h | 9 +- arch/arm/kernel/paravirt.c | 4 +- arch/arm/xen/enlighten.c | 34 --- arch/arm64/include/asm/paravirt.h | 9 +- arch/arm64/kernel/paravirt.c | 4 +- arch/x86/Kconfig | 4 + arch/x86/boot/compressed/misc.h | 1 + arch/x86/entry/entry_32.S | 8 +- arch/x86/entry/entry_64.S | 8 +- arch/x86/hyperv/mmu.c | 4 +- arch/x86/include/asm/debugreg.h | 2 +- arch/x86/include/asm/desc.h | 4 +- arch/x86/include/asm/fixmap.h | 2 +- arch/x86/include/asm/irqflags.h | 16 +- arch/x86/include/asm/mmu_context.h | 4 +- arch/x86/include/asm/msr.h | 4 +- arch/x86/include/asm/paravirt.h | 415 +++++++++++++--------------- arch/x86/include/asm/paravirt_types.h | 82 +++--- arch/x86/include/asm/pgalloc.h | 2 +- arch/x86/include/asm/pgtable-3level_types.h | 2 +- arch/x86/include/asm/pgtable.h | 7 +- arch/x86/include/asm/processor.h | 4 +- arch/x86/include/asm/ptrace.h | 2 +- arch/x86/include/asm/segment.h | 2 +- arch/x86/include/asm/special_insns.h | 4 +- arch/x86/kernel/alternative.c | 2 +- arch/x86/kernel/asm-offsets.c | 13 +- arch/x86/kernel/asm-offsets_64.c | 9 +- arch/x86/kernel/cpu/common.c | 4 +- arch/x86/kernel/cpu/vmware.c | 4 +- arch/x86/kernel/head_64.S | 2 +- arch/x86/kernel/kvm.c | 19 +- arch/x86/kernel/kvmclock.c | 4 +- arch/x86/kernel/paravirt-spinlocks.c | 15 +- arch/x86/kernel/paravirt.c | 305 ++++++++++---------- arch/x86/kernel/paravirt_patch_32.c | 57 ++-- arch/x86/kernel/paravirt_patch_64.c | 65 ++--- arch/x86/kernel/tsc.c | 2 +- arch/x86/kernel/vsmp_64.c | 26 +- arch/x86/mm/mem_encrypt_identity.c | 1 + arch/x86/xen/Kconfig | 1 + arch/x86/xen/Makefile | 41 ++- arch/x86/xen/efi.c | 14 +- arch/x86/xen/enlighten.c | 2 + arch/x86/xen/enlighten_hvm.c | 2 + arch/x86/xen/enlighten_pv.c | 31 ++- arch/x86/xen/grant-table.c | 25 +- arch/x86/xen/irq.c | 2 +- arch/x86/xen/mmu.c | 188 +------------ arch/x86/xen/mmu_hvm.c | 2 +- arch/x86/xen/mmu_pv.c | 168 ++++++++++- arch/x86/xen/p2m.c | 2 + arch/x86/xen/pci-swiotlb-xen.c | 2 + arch/x86/xen/platform-pci-unplug.c | 18 +- arch/x86/xen/spinlock.c | 11 +- arch/x86/xen/time.c | 4 +- arch/x86/xen/vdso.h | 2 + arch/x86/xen/xen-pvh.S | 15 +- drivers/xen/time.c | 2 +- include/xen/events.h | 2 + include/xen/interface/memory.h | 6 - include/xen/xen-ops.h | 133 ++++++--- 62 files changed, 880 insertions(+), 958 deletions(-) -- 2.16.4
