Some functions prototypes were missing for the non-altivec code. Add the
missing prototypes directly in xor_vmx, fix warnings treated as errors
with
W=1:

arch/powerpc/lib/xor_vmx_glue.c:18:6: error: no previous prototype for
âxor_altivec_2â [-Werror=missing-prototypes]
arch/powerpc/lib/xor_vmx_glue.c:29:6: error: no previous prototype for
âxor_altivec_3â [-Werror=missing-prototypes]
arch/powerpc/lib/xor_vmx_glue.c:40:6: error: no previous prototype for
âxor_altivec_4â [-Werror=missing-prototypes]
arch/powerpc/lib/xor_vmx_glue.c:52:6: error: no previous prototype for
âxor_altivec_5â [-Werror=missing-prototypes]

Only used in one place, should be static instead of adding it in a .h

Same for the other ones.

$ git grep xor_altivec_2
[...]
arch/powerpc/lib/xor_vmx_glue.c:EXPORT_SYMBOL(xor_altivec_2);

Are you sure I can change this function to static ?

Yes you are right. But in fact those fonctions are already defined in asm/xor. h
So you just need to add the missing #include
