CVS commit: src/lib/libpthread

Module Name:    src
Committed By:   matt
Date:           Thu Aug 16 04:49:48 UTC 2012

Modified Files:
        src/lib/libpthread: pthread_int.h pthread_mutex.c pthread_spin.c
        src/lib/libpthread/arch/arm: pthread_md.h

Log Message:
Add a pthread__smt_wake and add support for it on arm along with
pthread__smt_pause.  These are implemented using the ARM instructions
SEV (wake) and WFE (pause).  These are treated as NOPs on ARM CPUs that
don't support them.
