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-jgr...@suse.com/ which hides more Xen PV-only code behind CONFIG_XEN_PV. Changes in V2: - patch 4: shorten pv_ops sub-structure names (Jan Beulich) - patch 11: new patch Juergen Gross (11): 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 Xen-only 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/x86/Kconfig | 3 + 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 | 56 ++-- arch/x86/include/asm/mmu_context.h | 4 +- arch/x86/include/asm/msr.h | 4 +- arch/x86/include/asm/paravirt.h | 399 +++++++++++++--------------- arch/x86/include/asm/paravirt_types.h | 77 +++--- 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 | 3 +- 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 | 17 +- arch/x86/kernel/kvmclock.c | 4 +- arch/x86/kernel/paravirt-spinlocks.c | 15 +- arch/x86/kernel/paravirt.c | 292 ++++++++++---------- 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 | 24 +- arch/x86/xen/Kconfig | 1 + arch/x86/xen/enlighten_pv.c | 31 ++- arch/x86/xen/irq.c | 2 +- arch/x86/xen/mmu_hvm.c | 2 +- arch/x86/xen/mmu_pv.c | 28 +- arch/x86/xen/spinlock.c | 11 +- arch/x86/xen/time.c | 4 +- drivers/xen/time.c | 2 +- 39 files changed, 575 insertions(+), 595 deletions(-) -- 2.13.7 _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
