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.
