Has anyone successfully built a kernel with OpenVZ for 32-bit PPC?
I'm trying to apply the patch, but I keep getting compile errors. Here's the latest one:
LD [M] lib/zlib_inflate/zlib_inflate.o
Building modules, stage 2.
MODPOST
WARNING: "__cmpdi2" [fs/vzdquota.ko] undefined!
make[2]: *** [__modpost] Error 1
make[1]: *** [modules] Error 2
make[1]: Leaving directory `/usr/src/linux-source-2.6.18-openvz'
make: *** [debian/stamp-build-kernel] Error 2
I'm running Debian Etch on a G3 Mac. Kernel version is 2.6.18.

Update: I tried it again, this time with a vanilla 2.6.20 kernel, and the patch downloaded directly from openvz.org. Here are the exact steps that I followed:
- Download and unpack the 2.6.20 kernel sources from kernel.org.
- patch -p0 -i patch-ovz005.1-combined
- cp kernel-2.6.20-ppc64.config.ovz linux-2.6.20/.config
- make xconfig, and uncheck the PPC64 option - leave everything else the same.
- make-kpkg --rootcmd=sudo --initrd binary-arch
Here's the last thing I see from make-kpg: (the warnings about sched.h are repeated several hundred times - I have no idea if it's actually something I should be worried about.)
CC [M] fs/gfs2/glock.o
In file included from fs/gfs2/glock.c:10:

Does anybody have any suggestions?

I think I fixed it...
I found this thread, which talks about a similar problem:
http://www.ussg.iu.edu/hypermail/linux/kernel/0003.1/0565.ht ml
This would explain why it worked on 64-bit but not 32-bit: the 64-bit architecture can compare 64-bit integers natively, but on 32 bit, GCC needs to use a library function in libgcc.
I made the following change to fs/vzdq_file.c:
467c467
< switch ((long) n) {
---
> switch (n) {
I got it to build successfully, now I just have to get that bad boy installed and running... I'll let you know how it goes.

Still struggling...
make-kpkg failed to create the .deb file. No error message, the .deb just isn't there.
So I think, no problem, I'll just do a regular install and bypass the package manager. I run:
make headers_install
sudo make modules_install
sudo make install
The first two complete successfully, but the last one says:
make: *** No rule to make target `install'. Stop.
Any idea what went wrong?
If I can't fix it, can someone just tell me how to install it manually? I'm new to kernel hacking, so bear with me here.
