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

[Chris Zankel <chris@zankel.net>]

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.


Original message:

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
