Subject: [PATCH] vmlinux.lds.h: drop unused __vermagic

The reference to '__vermagic' is a relict from v2.5 times. And even
there it had a very short life time, from v2.5.59 (commit 1d411b80ee18
("Module Sanity Check") in the historic tree) to v2.5.69 (commit
67ac5b866bda ("[PATCH] complete modinfo section")).

Neither current kernels nor modules contain a '__vermagic' section any
more, so get rid of it.

Arnd, will you carry this patch through your asm-generic tree or did
the MAINTAINERS file mislead me here?

Thanks,
Mathias

looks like Arnd keeps ignoring my Emails. :/ Can you carry this patch
through your module tree? Or do you think I should ask Andrew Morton
instead?

Thanks,
Mathias

Sure, I'll queue this up in modules-next shortly after the merge window.

Oops, sorry about this.
