[PATCH v2 00/16] hw: Let DMA/PCI API take MemTxAttrs argument and propagate MemTxResult

[Philippe Mathieu-Daudé]

This is a respin of:

"dma: Let the DMA API take MemTxAttrs argument and propagate MemTxResult"
https://lists.gnu.org/archive/html/qemu-devel/2020-09/msg02048.html

and:
"pci: Let PCI DMA API functions propagate a MemTxResult"
https://lists.gnu.org/archive/html/qemu-devel/2020-09/msg02048.html

The DMA API propagates MemTxResult:
- MEMTX_OK,
- MEMTX_device_ERROR,
- MEMTX_DECODE_ERROR.

Let the PCI DMA API propagate them, as they are
clearer than an undocumented 'int'.

  pci: pass along the return value of dma_memory_rw
