Use ENTRY which is dedicated for global functions: * it aligns the functions properly * it is expected to have a corresponding ENDPROC too. startup_64, which uses .globl explicitly, is converted too. Besides that, x86's custom GLOBAL macro is going to die very soon. Signed-off-by: Jiri Slaby Cc: "H.
