Subject: [PATCH] powerpc: Fix build warning

If compiled with W=1, the following warning is seen in powerpc builds.

arch/powerpc/kernel/smp.c:750:18: warning:
	type qualifiers ignored on function return type
static const int powerpc_smt_flags(void)
                 ^

This is caused by a function returning 'const int', which doesn't
make sense to gcc. Drop 'const' to fix the problem.
