I'm a bit confused. Are you sure you have printed a long long
from kernel space?
Kernel space *printf is implemented in linux/lib/vsprintf.c.
Check it. It cannot handle long longs because 32 bit processors can
not divide them naturally. libc version of *printf() calls
64 bit arithmetic library functions.
