2.5.68-mm2+e100=trouble

2.5.68-mm2+e100=trouble

[jjs]

Hello -

This may be of interest...

kernel: 2.5.68-mm2

Linux distro: Red Hat 8.0 + updates

Hardware:
Celeron 1.2 Ghz on Intel Motherboard
512 MB RAM, 2x e100 ethernet

2.5.68-mm2 initially would not boot for me, and I noticed that
it was dying at the point where it was loading the e100 driver -

I booted -mm2 again specifying the eepro100 driver instead
and it came up fine.

To get another look at the e100 problem, I shut down networking
and removed the eepro100 module - all good, so far -

Then I said "modprobe e100" and the following oops occurred:

-------------------------- snip ------------------------------

You need to delete the __init from the definition of apply_alternatives().

Fixed (Was: 2.5.68-mm2+e100=trouble)

2.5.68-mm2+e100 are now happy together -

Thanks to Andrew Morton for the fix:

delete the __init from the definition of apply_alternatives()

BTW just to clarify:

Netiher 2.5.68 vanilla nor -mm1 manifested the problem -
