kernel vs userspace mismatch

kernel vs userspace mismatch

[Thomas Glanzmann]

Hello,
I run Linux HEAD and pulled in everything that is in the kvm git tree. I
also pulled the newest version of the userspace kvm repository.

But it doesn't compile:

        make -C user
        make[1]: Entering directory `/scratch/tg/kvm-userspace/user'
        cc -I /scratch/tg/linux-2.6/include -MMD -MF ./.kvmctl.d -g -fomit-frame-pointer -Wall -m32   -c -o kvmctl.o kvmctl.c
        kvmctl.c:30:2: error: #error libkvm: userspace and kernel version mismatch

Avi, did you forgot to push your changes to git.kernel.org?

        Thomas

I just sync'd the kernel and user repo and didn't have a problem.

The ABI changed twice in the last couple of days so make sure you've got 
an up-to-date userspace and kernel tree.
