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' kernel/built-in.o: In function `getnstimeofday': (.text+0x22330): undefined reference to `__umoddi3' kernel/built-in.o: In function `getnstimeofday': (.text+0x22350): undefined reference to `__udivdi3' kernel/built-in.o: In function `timekeeping_resume': timekeeping.c:(.text+0x226a0): undefined reference to `__udivdi3' timekeeping.c:(.text+0x22778): undefined reference to `__umoddi3' timekeeping.c:(.text+0x22798): undefined reference to `__udivdi3' kernel/built-in.o: In function `update_wall_time': (.text+0x22c7c): undefined reference to `__umoddi3' kernel/built-in.o: In function `update_wall_time': (.text+0x22c9c): undefined reference to `__udivdi3' kernel/built-in.o: In function `update_wall_time': (.text+0x230f8): undefined reference to `__umoddi3' kernel/built-in.o: In function `update_wall_time': (.text+0x23118): undefined reference to `__udivdi3' kernel/built-in.o: In function `do_settimeofday': (.text+0x23520): undefined reference to `__udivdi3' kernel/built-in.o: In function `timekeeping_init': (.init.text+0x1870): undefined reference to `__udivdi3' make[1]: *** [.tmp_vmlinux1] Error 1 But its not a regression, 2.6.24 allnoconfig does not link either on powerpc32.

You didn't mention your gcc version, but you should only get these errors when using the not yet released gcc 4.3. And this issue is known for at about half a year.
