Subject: [PATCH/RESEND] ARM: Remove __ref on hotplug cpu die path
Now that __cpuinit has been removed, the __ref markings on these
functions are useless. Remove them. This also reduces the size of
the multi_v7_defconfig image:
$ size before after
text data bss dec hex filename
12683578 1470996 348904 14503478 dd4e36 before
12683274 1470996 348904 14503174 dd4d06 after
presumably because now we don't have to jump to code in the
.ref.text section and/or the noinline marking is removed.
