[PATCH] x86/asm: Make more symbols local

[Jiri Slaby <jslaby@suse.cz>]

During the assembly cleanup patchset reveiew, I found more symbols which
are used only locally. So make them really local by prepending ".L" to
them. Namely:
* wakeup_idt is used only in realmode/rm/wakeup_asm.S.
* in_pm32 is used only in boot/pmjump.S.
* retint_user is used only in entry/entry_64.S, perhaps since commit
  2ec67971facc ("x86/entry/64/compat: Remove most of the fast system
  call machinery"), where entry_64_compat's caller was removed.

Drop GLOBAL from all of them too. I do not see more candidates in the
series.
