Your kernel still have references to symbols in discarded sections. Please
/* Functions marked as __devexit may be discarded at kernel link time, depending
on config options. Newer versions of binutils detect references from
retained sections to discarded sections and flag an error. Pointers to
__devexit functions must use __devexit_p(function_name), the wrapper will
insert either the function_name or NULL, depending on the config options.
#if defined(MODULE) || defined(CONFIG_HOTPLUG)
#define __devexit_p(x) x
#define __devexit_p(x) NULL
