2.2.2 compilation errors

[satadru pramanik]

Thanks again for all of the useful suggestions.  Further along the
compilation chain, i came across this fatal error with the pmac_ide stuff.
Luckily, since I have a 7600, w/o ide, i could just disable this, but it
would be nice to get this working in Linus' tree, since his tree is
mirrored everywhere.

This bug was introduced deliberately by Linus.
It was fixed for ppc yesterday by Paul Mackerras and Gary Thomas.

When the gods are busy, it's time for the prophets (self-proclaimed and
unauthorized as always). So here we go:

Today (tomorrow all this may have changed) you have two possibilities to
compile 2.2.2 on a ppc: Downgrade or upgrade.

1) Downgrade. Take the 2 files kernel/ksyms.c and kernel/sched.c from a
previous version. For your convenience, I have put them on my site
http://www.maths.univ-rennes1.fr/~costabel/linux/boot/

2) Upgrade. Take the 2 files include/asm-ppc/semaphore.h and
include/asm-ppc/semaphore-helper.h from the cvs tree at samba.anu.edu.au
(or take the whole tree; it contains many other bug fixes). On my Web
site, I have a file kernel222-samba.diff that patches these 2 files. It
is only 5kB, so this is the simplest way to go.
