  Modified files:
    sys/sys              mutex.h 
  Log:
  - Add a new macro DROP_GIANT_NOSWITCH() that is similar to DROP_GIANT()
    except that it uses the MTX_NOSWITCH flag while it releases Giant via
    mtx_exit().
  - Add a mtx_recursed() primitive.  This primitive should only be used on
    a mutex owned by the current process.  It will return non-zero if the
    mutex is recursively owned, or zero otherwise.
  - Add two new flags MA_RECURSED and MA_NOTRECURSED that can be used in
    conjuction with MA_OWNED to control the assertion checked by mtx_assert().
  - Fix some of the KTR tracepoint strings to use %p when displaying the lock
    field of a mutex, which is a uintptr_t.
