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

>> WARNING: modpost: vmlinux.o(.text.unlikely+0x156c): Section mismatch in reference from the function bitmap_equal() to the variable .init.data:initcall_level_names
The function bitmap_equal() references
the variable __initdata initcall_level_names.
This is often because bitmap_equal lacks a __initdata
annotation or the annotation of initcall_level_names is wrong.

The below error/warnings are from parent commit:
<< WARNING: modpost: vmlinux.o(.data+0x1a86d8): Section mismatch in reference from the variable qed_mfw_legacy_maps to the variable .init.rodata:__setup_str_initcall_blacklist
