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

>> WARNING: modpost: vmlinux.o(.text+0x144bfc): Section mismatch in reference from the function tracefs_init() to the function .init.text:set_reset_devices()
The function tracefs_init() references
the function __init set_reset_devices().
This is often because tracefs_init lacks a __init
annotation or the annotation of set_reset_devices is wrong.
