[PULL REQUEST for 3.7-rc4] xtensa: fix syscall table and vfork, and switch to generic thread/execve

[PULL REQUEST for 3.7-rc4] xtensa: fix syscall table and vfork, and switch to generic thread/execve

[Chris Zankel]

Hi Linus,

Would be great if you could pull the Xtensa tree for some important bug
fixes. With the change to uapi, there was a bug introduced that results
in an empty syscall table (mult-inclusion bug). Switching to the generic
thread/execve allowed us to fix a bug we had in vfork().

Thanks,
-Chris

We've been here before, haven't we? There's so much wrong with this
that it's not funny.

I don't want https addresses. Yes, I suspect github uses the smart
streaming git mode, but you can't tell by the address, and it's
annoying. Github supports the native git protocol, just show that in
the address, and don't make me have to edit it for stupid reasons. So
the repository address should be

    git://github.com/czankel/xtensa-linux.git for_next

.. which brings us to the other problem. I don't do unsigned pulls
from public hosting places. Anybody can put up a github repo, and
people do.

So unless the hosting itself is limited to people I can trust some
other way (ie notably kernel.org, but there are other "controlled
hosting" places too), I really *really* want to see tags with gpg
signatures. Which the above is not.

And I know you can do them, because you've done them in the past. So
please don't continue to do the above.

[PULL REQUEST for 3.7-rc4 - second attempt] xtensa: fix syscall table and vfork, and switch to generic thread/execve

[Chris Zankel]

Hi Linus,

Sorry for the mishap with my previous attempt. I noted the change to use
the git protocol, so it won't happen again (I think I actually used the
wrong one also the past two times). Regarding the invalid tag, I hadn't
pushed the tag up before creating the message, so git-request-pull seems
to have defaulted to the previous tag (or branch name?), and no warning.
I'll verify the tag next time.
