x86/efi: Mark initialization code as such
The 32 bit and 64 bit implementations differ in their __init annotations for some functions referenced from the common EFI code. Namely, the 32 bit variant is missing some of the __init annotations the 64 bit variant has. To solve the colliding annotations, mark the corresponding functions in efi_32.c as initialization code, too -- as it is such. Actually, quite a few more functions are only used during initialization and therefore can be marked __init. They are therefore annotated, too. Also add the __init annotation to the prototypes in the efi.h header so users of those functions will see it's meant as initialization code only. This patch also fixes the "prelog" typo. ("prologue" / "epilogue" might be more appropriate but this is C code after all, not an opera! :D) Signed-off-by: Mathias Krause <minipli@googlemail.com> Signed-off-by: Matt Fleming <matt.fleming@intel.com>
