It is from UML. 'bk -r grep __bb_init_func' gives:
arch/um/kernel/gmon_syms.c 1.1 extern void __bb_init_func(void *); arch/um/kernel/gmon_syms.c 1.1 EXPORT_SYMBOL(__bb_init_func);
The kernel compiles fine with the same .config but TT mode also enabled.
So I suspect that in the non-TT case the gmon_syms binary doesn't get linked into the kernel so the symbol is missing or something like that...
Also note I am using the latest BK as pulled about an hour ago. I don't know how old the snapshot you are using is in comparison. Lots of UML changes were pulled in by my pull...
