All warnings (new ones prefixed by >>, old ones prefixed by <<):

>> WARNING: modpost: vmlinux.o(.text.unlikely+0x253ac): Section mismatch in reference from the function __set_bit() to the variable .init.data:initcall_level_names
The function __set_bit() references
the variable __initdata initcall_level_names.
This is often because __set_bit lacks a __initdata
annotation or the annotation of initcall_level_names is wrong.

The below error/warnings are from parent commit:
