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

From: 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
