Subject: undefined references to __udivdi3 on powerpc


While debugging __divdi3 calls in drivers/crypto/hifn_795x.c (due to the
ndelay() delay call with a s64), I found even more breakage of that
sort. This is after a allnoconfig with ARCH=powerpc in 2.6.25-rc3,
plus CONFIG_MODULES=y and CONFIG_CRYPTO_DEV_HIFN_795X=y:

  LD      .tmp_vmlinux1
  kernel/built-in.o: In function `update_xtime_cache':
  (.text+0x221a0): undefined reference to `__umoddi3'
  kernel/built-in.o: In function `update_xtime_cache':
  (.text+0x221c0): undefined reference to `__udivdi3'

  (.text+0x22330): undefined reference to `__umoddi3'
  kernel/built-in.o: In function `getnstimeofday':

  kernel/built-in.o: In function `timekeeping_init':

  make[1]: *** [.tmp_vmlinux1] Error 1

But its not a regression, 2.6.24 allnoconfig does not link either on
powerpc32. 

How can this be fixed?
