Looking around with "git grep", there's a few more of these.

 - btrfs seems to like "(unsigned long)-1"

   There's a few other users of that too, including more sparc uses.

 - scsi/qla seems to like "(unsigned long)<hexnumber>"

 - fmdrv_common.h seems to like "((unsigned long)1<<x)" for bitmaps

along with a smattering of random noise all over of "(unsigned long)
n" where 'n' is some integer.

Apparently people aren't as aware of the normal "ul" postfix syntax as
I would have expected. That said, it's a hundred-odd cases in all of
the kernel, so it's still fairly rare.
