Subject: linux-next: net tree build failure

Hi all,

Today's linux-next build (powerpc_allnoconfig) failed like this:

lib/lib.a(vsprintf.o): In function `pointer':
vsprintf.c:(.text+0x21ba): undefined reference to `byte_rev_table'
vsprintf.c:(.text+0x21c2): undefined reference to `byte_rev_table'

Caused by commit bc7259a2ce764ea16200eb9e53f6e136e918d065
("lib/vsprintf.c: Add %pMF to format FDDI bit reversed MAC addresses")
from the net tree.

I applied the following fixup patch (and can carry it for a while):
(BTW after this patch, CONFIG_BITREVERSE appears to not be used anywhere
except where is is selected in Kconfig files.)
