Quite simple really:

$ cat > t.s
.word 0xee190f11
.word 0xee190f31
$ arm-linux-as -o t.o t.s
$ arm-linux-objdump -d t.o
...
00000000 <.text>:
   0:   ee190f11        mrc     15, 0, r0, cr9, cr1, {0}
   4:   ee190f31        mrc     15, 0, r0, cr9, cr1, {1}

Those two words being the values which fit the word and mask you
specified, omitting the usual location for Rd (which is normally bits
12:16 in ARM instructions).  Of course, a couple more words would
confirm that.
