From 0865e636aef751966e6e0f8950a26bc7391e923c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Radim=20Kr=C4=8Dm=C3=A1=C5=99?= Date: Thu, 28 Aug 2014 15:13:02 +0200 Subject: KVM: static inline empty kvm_arch functions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Using static inline is going to save few bytes and cycles. For example on powerpc, the difference is 700 B after stripping. (5 kB before) This patch also deals with two overlooked empty functions: kvm_arch_flush_shadow was not removed from arch/mips/kvm/mips.c 2df72e9bc KVM: split kvm_arch_flush_shadow and kvm_arch_sched_in never made it into arch/ia64/kvm/kvm-ia64.c. e790d9ef6 KVM: add kvm_arch_sched_in Signed-off-by: Radim Krčmář Signed-off-by: Paolo Bonzini --- arch/ia64/include/asm/kvm_host.h | 12 ++++++++++++ arch/ia64/kvm/kvm-ia64.c | 30 ------------------------------ 2 files changed, 12 insertions(+), 30 deletions(-) (limited to 'arch/ia64') diff --git a/arch/ia64/include/asm/kvm_host.h b/arch/ia64/include/asm/kvm_host.h index fccc09d..4729752 100644 --- a/arch/ia64/include/asm/kvm_host.h +++ b/arch/ia64/include/asm/kvm_host.h @@ -592,6 +592,18 @@ void kvm_sal_emul(struct kvm_vcpu *vcpu); struct kvm *kvm_arch_alloc_vm(void); void kvm_arch_free_vm(struct kvm *kvm); +static inline void kvm_arch_sync_events(struct kvm *kvm) {} +static inline void kvm_arch_vcpu_put(struct kvm_vcpu *vcpu) {} +static inline void kvm_arch_sched_in(struct kvm_vcpu *vcpu) {} +static inline void kvm_arch_free_memslot(struct kvm *kvm, + struct kvm_memory_slot *free, struct kvm_memory_slot *dont) {} +static inline void kvm_arch_memslots_updated(struct kvm *kvm) {} +static inline void kvm_arch_commit_memory_region(struct kvm *kvm, + struct kvm_userspace_memory_region *mem, + const struct kvm_memory_slot *old, + enum kvm_mr_change change) {} +static inline void kvm_arch_hardware_unsetup(void) {} + #endif /* __ASSEMBLY__*/ #endif diff --git a/arch/ia64/kvm/kvm-ia64.c b/arch/ia64/kvm/kvm-ia64.c index 0729ba6..5e14dca 100644 --- a/arch/ia64/kvm/kvm-ia64.c +++ b/arch/ia64/kvm/kvm-ia64.c @@ -1364,10 +1364,6 @@ static void kvm_release_vm_pages(struct kvm *kvm) } } -void kvm_arch_sync_events(struct kvm *kvm) -{ -} - void kvm_arch_destroy_vm(struct kvm *kvm) { kvm_iommu_unmap_guest(kvm); @@ -1376,10 +1372,6 @@ void kvm_arch_destroy_vm(struct kvm *kvm) kvm_release_vm_pages(kvm); } -void kvm_arch_vcpu_put(struct kvm_vcpu *vcpu) -{ -} - void kvm_arch_vcpu_load(struct kvm_vcpu *vcpu, int cpu) { if (cpu != vcpu->cpu) { @@ -1468,7 +1460,6 @@ void kvm_arch_vcpu_uninit(struct kvm_vcpu *vcpu) kfree(vcpu->arch.apic); } - long kvm_arch_vcpu_ioctl(struct file *filp, unsigned int ioctl, unsigned long arg) { @@ -1551,21 +1542,12 @@ int kvm_arch_vcpu_fault(struct kvm_vcpu *vcpu, struct vm_fault *vmf) return VM_FAULT_SIGBUS; } -void kvm_arch_free_memslot(struct kvm *kvm, struct kvm_memory_slot *free, - struct kvm_memory_slot *dont) -{ -} - int kvm_arch_create_memslot(struct kvm *kvm, struct kvm_memory_slot *slot, unsigned long npages) { return 0; } -void kvm_arch_memslots_updated(struct kvm *kvm) -{ -} - int kvm_arch_prepare_memory_region(struct kvm *kvm, struct kvm_memory_slot *memslot, struct kvm_userspace_memory_region *mem, @@ -1597,14 +1579,6 @@ int kvm_arch_prepare_memory_region(struct kvm *kvm, return 0; } -void kvm_arch_commit_memory_region(struct kvm *kvm, - struct kvm_userspace_memory_region *mem, - const struct kvm_memory_slot *old, - enum kvm_mr_change change) -{ - return; -} - void kvm_arch_flush_shadow_all(struct kvm *kvm) { kvm_flush_remote_tlbs(kvm); @@ -1853,10 +1827,6 @@ int kvm_arch_hardware_setup(void) return 0; } -void kvm_arch_hardware_unsetup(void) -{ -} - int kvm_apic_set_irq(struct kvm_vcpu *vcpu, struct kvm_lapic_irq *irq) { return __apic_accept_irq(vcpu, irq->vector); -- cgit v1.1
