> Hey all-

> It got acks from the kexec folks so I pulled it into RHEL, but I never checked
> back here to make sure it ever made it in, which apparently it didn't. It still
> needs to be included, so I'm reposting it here, making sure to copy all the ppc
> folks this time. I've retested it on the latest linus kernel and it works fine,
> allowing makedumpfile to find all the symbols it needs to properly strip a
> vmcore on ppc64.
