  Modified files:
    sys/alpha/alpha      machdep.c 
    sys/alpha/include    cpu.h fpu.h signal.h ucontext.h 
    sys/conf             files 
    sys/i386/i386        machdep.c 
    sys/i386/include     signal.h ucontext.h 
    sys/i386/isa         npx.c 
    sys/ia64/ia64        machdep.c 
    sys/kern             syscalls.master 
    sys/powerpc/powerpc  machdep.c 
    sys/sparc64/sparc64  machdep.c 
    sys/sys              ucontext.h 
  Added files:
    sys/kern             kern_context.c 
  Log:
  Add getcontext, setcontext, and swapcontext as system calls.
  Previously these were libc functions but were requested to
  be made into system calls for atomicity and to coalesce what
  might be two entrances into the kernel (signal mask setting
  and floating point trap) into one.
  
  A few style nits and comments from bde are also included.
