Module Name:    src

Modified Files:
        src/lib/libpthread/arch/alpha: pthread_switch.S
        src/lib/libpthread/arch/arm: pthread_switch.S
        src/lib/libpthread/arch/i386: pthread_switch.S
        src/lib/libpthread/arch/powerpc: pthread_switch.S

Log Message:
Two fixes:
 * In switch-away cases, write PT_SWITCHTO last (after PT_SWITCHTOUC), so
   that pthread__resolve_locks() doesn't see an empty SWITCHTOUC value. This
   also permits pthread__resolve_locks() to use the presence of PT_SWITCHTO
   as a sign that the thread has done all of its necessary chain work.

 * Make the return-point of pthread__switch global and visible, so that its
   address can be compared to the PC of a thread, again as a sign that its
   chain-work is done.

(other architectures in progress, after they get the *previous* asm fix...)
