Patch is now in Linus's tree:

commit 145e1c0023585e0e8f6df22316308ec61c5066b2
Author: Hugh Dickins <[email protected]>
Date: Sat Nov 1 21:41:40 2008 -0700

sparc64: Fix __copy_{to,from}_user_inatomic defines.

Alexander Beregalov reports oops in __bzero() called from
copy_from_user_fixup() called from iov_iter_copy_from_user_atomic(),
when running dbench on tmpfs on sparc64: its __copy_from_user_inatomic
and __copy_to_user_inatomic should be avoiding, not calling, the fixups.

Been trying to reproduce this one since I saw it, and I think it can
be written off as can't reproduce :-(

Maybe I can contribute a patch that verifies that the return value ==
strlen(buffer), WARN_ON otherwise? And hope that somebody runs into
it.

Yep, should still be listed. As mentioned in the BZ entry, there is a
proposed patch here:

http://lkml.org/lkml/2008/11/1/61

I'm waiting for feedback from the people who have run accross the bug.

Yup, should still be listed.

Is someone looking what the proper fix should be (other than reverting
the commit in question)? I've been running with the commit reverted
on my laptop kernel for a couple of days now, with no problems.
