  Modified files:
    sys/vm               vm_mmap.c 
  Log:
  - Obtain Giant in mmap() syscall while messing with file descriptors and
    vnodes.
  - Fix an old bug that would leak a reference to a fd if the vnode being
    mmap'd wasn't of type VREG or VCHR.
  - Lock Giant in vm_mmap() around calls into the VM that can call into
    pager routines that need Giant or into other VM routines that need
    Giant.
  - Replace code that used a goto to jump around the else branch of a test
    to use an else branch instead.
