Add missing <linux/kernel.h> include.
The min_t macro is defined in <linux/kernel.h>.
On x86 <linux/kernel.h> is included indirectly
via <asm/unaligned.h>, thus the missing include
wasn't caught on x86.
Since <linux/kernel.h> always includes <asm/byteorder.h>,
there's no need to include the latter explicitly.
Thanks to Russel King and and Imre Kaloz.
