This is not sufficient. If CONFIG_HOTPLUG is defined,
__devinit sections are still included in vmlinux. This
is because those functions are required for hot-unplugging.
This patch will cause hot-unplug for statically linked drivers
to not work correctly, because the ->remove() method isn't
available (it has a null pointer).
The ifdef needs to be:
#if defined(MODULE) || defined(CONFIG_HOTPLUG)
I've just send a patch, which alters 59 kernel files to
the kernel list. It's for 2.4.17-pre2 and will hopefully
appear in 2.4.17-pre3.
The easiest fix for earlier kernels is to edit arch/i386/vmlinux.lds.in
and delete the entire /DISCARD/ section.
