Subject: 2.6.32-rc3: floating-point build failure (undefined reference to
	`__udivdi3' in menu governor)

Hi,

didn't find any report about this, so...

  LD      .tmp_vmlinux1
drivers/built-in.o(.text+0xd85a1): In function `menu_select':
drivers/cpuidle/governors/menu.c:212: undefined reference to `__udivdi3'
make: *** [.tmp_vmlinux1] Error 1


The symbol being __udivdi3 sounds to me like it's illegal FP use here.

This is not necessarily a -rc3 regression, though (currently running
2.6.29-rc7 on this box).
