powerpc/mm: fix section mismatch for setup_kup()
commit b28c97505eb1 ("powerpc/64: Setup KUP on secondary CPUs") moved setup_kup() out of the __init section. As stated in that commit, "this is only for 64-bit". But this function is also used on PPC32, where the two functions called by setup_kup() are in the __init section, so setup_kup() has to either be kept in the __init section on PPC32 or marked __ref. This patch marks it __ref, it fixes the below build warnings. MODPOST vmlinux.o WARNING: vmlinux.o(.text+0x169ec): Section mismatch in reference from the function setup_kup() to the function .init.text:setup_kuep() The function setup_kup() references the function __init setup_kuep(). This is often because setup_kup lacks a __init annotation or the annotation of setup_kuep is wrong. WARNING: vmlinux.o(.text+0x16a04): Section mismatch in reference from the function setup_kup() to the function .init.text:setup_kuap() The function setup_kup() references the function __init setup_kuap(). This is often because setup_kup lacks a __init annotation or the annotation of setup_kuap is wrong.
