Subject[PATCH 2/2] x86: entry, use ENTRY instead of ALIGN+GLOBAL for stub32_clone
Date
ALIGN+GLOBAL is effectively what ENTRY does, so use ENTRY which is
dedicated for exactly this purpose -- global functions.

Note that stub32_clone is a C-like leaf function -- it has a standard
call frame -- it only switches one argument and continues by jumping
into C. And since each ENTRY should be balanced by some END*, we add a
corresponding ENDPROC to stub32_clone too.

Besides that, x86's custom GLOBAL macro is going to die very soon.
