This adds support for the pselect and ppoll system calls on x86_64.
Andi suggests that it might be too late for the 2.6.18 merge window -- I
disagree. I consider it a bug fix, since I don't think we intend x86_64
to be a secondary architecture and lag behind i386 and PowerPC in its
system call support. Andi's TIF_RESTORE_SIGMASK implementation is
heavily based on the i386 version, where it's had lots of testing
already.
