[PATCH] x86/cpu_entry_area: Annotate percpu_setup_exception_stacks() as __init

[Nathan Chancellor]

After a recent LLVM change [1] that deduces __cold on functions that
only call cold code (such as __init functions), there is a section
mismatch warning from percpu_setup_exception_stacks(), which got moved
to .text.unlikely. as a result of that optimization:

  WARNING: modpost: vmlinux: section mismatch in reference: percpu_setup_exception_stacks+0x3a (section: .text.unlikely.) -> cea_map_percpu_pages (section: .init.text)

Drop the inline keyword (which does not guarantee inlining) and replace
it with __init, as percpu_setup_exception_stacks() is only called from
__init code, which clears up the warning.
