Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma

Pull rdma fixes from Jason Gunthorpe:
 "Fix two build warnings on 32 bit platforms

  It seems the linux-next CI and 0-day bot are not testing enough 32 bit
  configurations, as soon as you merged the rdma pull request there were
  two instant reports of warnings on these sytems that I would have
  thought should have been covered by time in linux-next

  Anyhow, here are the fixes so people don't hit problems with -Werror"

* tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma:
  RDMA/siw: Fix pointer cast warning
  RDMA/rxe: Fix compile warnings on 32-bit
