Hi Changbin,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on linus/master]
[also build test WARNING on v4.17-rc4 next-20180509]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

config: i386-allmodconfig (attached as .config)
compiler: gcc-7 (Debian 7.3.0-16) 7.3.0
reproduce:
        # save the attached .config to linux build tree
        make ARCH=i386 

All warnings (new ones prefixed by >>):

>> WARNING: vmlinux.o(.text.unlikely+0xce5): Section mismatch in reference from the function init_xstate_size() to the function .init.text:get_xsave_size()
   The function init_xstate_size() references
   the function __init get_xsave_size().
   This is often because init_xstate_size lacks a __init
   annotation or the annotation of get_xsave_size is wrong.
--
>> WARNING: vmlinux.o(.text.unlikely+0xcf7): Section mismatch in reference from the function init_xstate_size() to the function .init.text:get_xsaves_size()
   The function init_xstate_size() references
   the function __init get_xsaves_size().
   This is often because init_xstate_size lacks a __init
   annotation or the annotation of get_xsaves_size is wrong.
--
>> WARNING: vmlinux.o(.text.unlikely+0x22a6): Section mismatch in reference from the function percpu_setup_debug_store() to the function .init.text:cea_map_percpu_pages()
   The function percpu_setup_debug_store() references
   the function __init cea_map_percpu_pages().
   This is often because percpu_setup_debug_store lacks a __init
   annotation or the annotation of cea_map_percpu_pages is wrong.
--
>> WARNING: vmlinux.o(.text.unlikely+0x2564): Section mismatch in reference from the function can_free_region() to the function .init.text:e820__mapped_all()
   The function can_free_region() references
   the function __init e820__mapped_all().
   This is often because can_free_region lacks a __init
   annotation or the annotation of e820__mapped_all is wrong.
