X-Git-Tag: firefly_0821_release~7613^2~1405^2 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=7c1bfd685bcdc822ab1d7411ea05c82bd2a7b260;p=firefly-linux-kernel-4.4.55.git xen/pci: Fix compiler error when CONFIG_XEN_PRIVILEGED_GUEST is not set. If we have CONFIG_XEN and the other parameters to build an Linux kernel that is non-privileged, the xen_[find|register|unregister]_ device_domain_owner functions should not be compiled. They should use the nops defined in arch/x86/include/asm/xen/pci.h instead. This fixes: arch/x86/pci/xen.c:496: error: redefinition of ‘xen_find_device_domain_owner’ arch/x86/include/asm/xen/pci.h:25: note: previous definition of ‘xen_find_device_domain_owner’ was here arch/x86/pci/xen.c:510: error: redefinition of ‘xen_register_device_domain_owner’ arch/x86/include/asm/xen/pci.h:29: note: previous definition of ‘xen_register_device_domain_owner’ was here arch/x86/pci/xen.c:532: error: redefinition of ‘xen_unregister_device_domain_owner’ arch/x86/include/asm/xen/pci.h:34: note: previous definition of ‘xen_unregister_device_domain_owner’ was here Signed-off-by: Konrad Rzeszutek Wilk Reported-by: Randy Dunlap --- diff --git a/arch/x86/pci/xen.c b/arch/x86/pci/xen.c index 393981feb12f..8214724ce54d 100644 --- a/arch/x86/pci/xen.c +++ b/arch/x86/pci/xen.c @@ -473,6 +473,7 @@ void __init xen_setup_pirqs(void) } #endif +#ifdef CONFIG_XEN_DOM0 struct xen_device_domain_owner { domid_t domain; struct pci_dev *dev; @@ -545,3 +546,4 @@ int xen_unregister_device_domain_owner(struct pci_dev *dev) return 0; } EXPORT_SYMBOL_GPL(xen_unregister_device_domain_owner); +#endif
