On a kernel config with ALTIVEC=y and PPC_FPU not set/enabled, there are build errors: drivers/cpufreq/pmac32-cpufreq.c:262:2: error: implicit declaration of function 'enable_kernel_fp' [-Werror,-Wimplicit-function-declaration] enable_kernel_fp(); ../arch/powerpc/lib/sstep.c: In function 'do_vec_load': ../arch/powerpc/lib/sstep.c:637:3: error: implicit declaration of function 'put_vr' [-Werror=implicit-function-declaration] 637 | put_vr(rn, &u.v); | ^~~~~~ ../arch/powerpc/lib/sstep.c: In function 'do_vec_store': ../arch/powerpc/lib/sstep.c:660:3: error: implicit declaration of function 'get_vr'; did you mean 'get_oc'? [-Werror=implicit-function-declaration] 660 | get_vr(rn, &u.v); | ^~~~~~ In theory ALTIVEC is independent of PPC_FPU but in practice nobody is going to build such a machine, so make ALTIVEC require PPC_FPU by selecting it.
