xen: annotate functions which only call into __init at start of day
Both xen_hvm_init_shared_info and xen_build_mfn_list_list can be called at resume time as well as at start of day but only reference __init functions (extend_brk) at start of day. Hence annotate with __ref. WARNING: arch/x86/built-in.o(.text+0x4f1): Section mismatch in reference from the function xen_hvm_init_shared_info() to the function .init.text:extend_brk() The function xen_hvm_init_shared_info() references the function __init extend_brk(). This is often because xen_hvm_init_shared_info lacks a __init annotation or the annotation of extend_brk is wrong. xen_hvm_init_shared_info calls extend_brk() iff !shared_info_page and initialises shared_info_page with the result. This happens at start of day only. WARNING: arch/x86/built-in.o(.text+0x599b): Section mismatch in reference from the function xen_build_mfn_list_list() to the function .init.text:extend_brk() The function xen_build_mfn_list_list() references the function __init extend_brk(). This is often because xen_build_mfn_list_list lacks a __init annotation or the annotation of extend_brk is wrong. (this warning occurs multiple times) xen_build_mfn_list_list only calls extend_brk() at boot time, while building the initial mfn list list Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
