Add a special-case handler for general protection faults.  It appears to
be possible to get the swapgs state reversed if doreti traps during
the iretq.  Attempt to handle this.  load_gs() might need special
handling too.  Running the kernel with the user's TLS and the
kernel's PCPU space interchanged would be bad(TM).

Discovered as a result of a conversation with:  bde
