Merge tag 'dma-mapping-5.7' of git://git.infradead.org/users/hch/dma-mapping

Pull dma-mapping updates from Christoph Hellwig:

 - fix an integer overflow in the coherent pool (Kevin Grandemange)

 - provide support for in-place uncached remapping and use that for
   openrisc

 - fix the arm coherent allocator to take the bus limit into account

  ARM/dma-mapping: merge __dma_supported into arm_dma_supported
  ARM/dma-mapping: take the bus limit into account in __dma_alloc
  ARM/dma-mapping: remove get_coherent_dma_mask
  openrisc: use the generic in-place uncached DMA allocator
  dma-direct: provide a arch_dma_clear_uncached hook
  dma-direct: make uncached_kernel_address more general
