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

>> WARNING: modpost: vmlinux.o(.text.unlikely+0xeee4): Section mismatch in reference from the variable $c to the variable .init.data:bitmap
The function $c() references
the variable __initdata bitmap.
This is often because $c lacks a __initdata
annotation or the annotation of bitmap is wrong.
