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

Pull rdma fixes from Jason Gunthorpe:
 "The last two weeks have been quiet here, just the usual smattering of
  long standing bug fixes.

  A collection of error case bug fixes:

   - Improper nesting of spinlock types in cm

   - Missing error codes and kfree()

   - Ensure dma_virt_ops users have the right kconfig symbols to work
     properly

   - Compilation failure of tools/testing"

* tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma:
  tools/testing/scatterlist: Fix test to compile and run
  IB/hfi1: Fix error return code in hfi1_init_dd()
  RMDA/sw: Don't allow drivers using dma_virt_ops on highmem configs
  RDMA/pvrdma: Fix missing kfree() in pvrdma_register_device()
  RDMA/cm: Make the local_id_table xarray non-irq
