From: Zengruan Ye <yezengruan@huawei.com> virt inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4VZPC CVE: NA -------------------------------- Commit 63042c58affc ("KVM: arm64: Add interface to support vCPU preempted check") introduced paravirt spinlock operations, as pv_lock_ops was exported via EXPORT_SYMBOL(), while the pv_ops structure containing the pv lock operations is exported via EXPORT_SYMBOL_GPL(). Change that by using EXPORT_SYMBOL(pv_ops) for arm/arm64, as with the x86 architecture changes, the following: https://lore.kernel.org/all/20181029150116.25372-1-jgross@suse.com/T/#u Fixes: 63042c58affc ("KVM: arm64: Add interface to support vCPU preempted check") Signed-off-by: yezengruan <yezengruan@huawei.com> Reviewed-by: Keqian Zhu <zhukeqian1@huawei.com> Acked-by: Xie Xiuqi <xiexiuqi@huawei.com> Signed-off-by: Zheng Zengkai <zhengzengkai@huawei.com> --- arch/arm/kernel/paravirt.c | 2 +- arch/arm64/kernel/paravirt.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/arm/kernel/paravirt.c b/arch/arm/kernel/paravirt.c index 4cfed91fe256..3c34f456e400 100644 --- a/arch/arm/kernel/paravirt.c +++ b/arch/arm/kernel/paravirt.c @@ -15,4 +15,4 @@ struct static_key paravirt_steal_enabled; struct static_key paravirt_steal_rq_enabled; struct paravirt_patch_template pv_ops; -EXPORT_SYMBOL_GPL(pv_ops); +EXPORT_SYMBOL(pv_ops); diff --git a/arch/arm64/kernel/paravirt.c b/arch/arm64/kernel/paravirt.c index 847b3c8b1218..ecbd2bf2e6fb 100644 --- a/arch/arm64/kernel/paravirt.c +++ b/arch/arm64/kernel/paravirt.c @@ -38,7 +38,7 @@ struct paravirt_patch_template pv_ops = { #endif .lock.vcpu_is_preempted = __native_vcpu_is_preempted, }; -EXPORT_SYMBOL_GPL(pv_ops); +EXPORT_SYMBOL(pv_ops); struct pv_time_stolen_time_region { struct pvclock_vcpu_stolen_time *kaddr; -- 2.20.1
