  Modified files:
    lib/libc/amd64/sys   Makefile.inc 
  Added files:
    lib/libc/amd64/sys   getcontext.S 
  Log:
  Apply same basic fix for getcontext(2) as for i386.  Store the return
  value for getcontext() in a preserved register rather than on the stack.
  The second time around, the stack value would likely have changed so we
  can't depend on it for the return value.
