All warnings (new ones prefixed by >>, old ones prefixed by <<):
<< WARNING: modpost: vmlinux.o(.text.unlikely+0x3dbc): Section mismatch in reference from the function memcpy_from_page.part.0() to the variable .init.data:initcall_level_names >> WARNING: modpost: vmlinux.o(.text.unlikely+0x3d44): Section mismatch in reference from the function sg_page.isra.0.part.0() to the variable .init.data:initcall_level_names The function sg_page.isra.0.part.0() references the variable __initdata initcall_level_names. This is often because sg_page.isra.0.part.0 lacks a __initdata annotation or the annotation of initcall_level_names is wrong.
