The NESTED_FUNC_ATTR is need for buggy versions of gcc, because we
compile i386 grub (bootime) with mregparm=3. And there are versions of
gcc that don't save content of one of registers when calling such
function or something similar.

My opinion on mregparm=3 is not good, because this is only obstacle (and
it is BIG obstacle) to use same modules at boottime and in posix-userland.
