x86/asm: Make more symbols local
During the assembly cleanup patchset review, 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.
