Subject: smart gcc inliner...

Hi,

The recent gcc (3.4/4.x) optimizer inlines functions across
sections which is definitely not we want, e.g. inlining
functions from .init.text section.

I think, the `__init' macro needs `noinline' attribute and all
the `static inline __{dev}init' functions need `inline' attribute
removal to avoid gcc error (inlining failed, function not inlinable).

BR,
Pawel.
