    sys/sys              kse.h proc.h syscall.h syscall.mk 
                         sysproto.h 
    sys/kern             init_sysent.c kern_sig.c kern_synch.c

                         syscalls.master 
  Log:
  o Change kse_thr_interrupt to allow send a signal to a specified thread,
    or unblock a thread in kernel, and allow UTS to specify whether syscall
    should be restarted.
  o Add ability for UTS to monitor signal comes in and removed from process,
    the flag PS_SIGEVENT is used to indicate the events.
  o Add a KMF_WAITSIGEVENT for KSE mailbox flag, UTS call kse_release with
    this flag set to wait for above signal event.
  o For SA based thread, kernel masks all signal in its signal mask, let
    UTS to use kse_thr_interrupt interrupt a thread, and install a signal
    frame in userland for the thread.
  o Add a tm_syncsig in thread mailbox, when a hardware trap occurs,
    it is used to deliver synchronous signal to userland, and upcall
    is schedule, so UTS can process the synchronous signal for the thread.
