Dear Benjamin Herrenschmidt,

It seems this commit broke ALTIVEC-enablked 32 bit systems. For
example, when trying to build 86xx/mpc8641_hpcn_defconfig I get:

arch/powerpc/kernel/vector.S: Assembler messages:
arch/powerpc/kernel/vector.S:61: Error: Unrecognized opcode: `cmpdi'
make[1]: *** [arch/powerpc/kernel/vector.o] Error 1

Segher suggests to s/cmpdi/cmplwi/ which indeed seems to work (atleast
it allows me to build the kernel image).

Best regards,

Wolfgang Denk
