[PATCH v2 00/17] hw/block/nvme: multiple namespaces support |

From: Klaus Jensen <k.jensen@samsung.com>
This is the next round of my patches for the nvme device.
This includes a bit of cleanup and two new features:
* support for scatter/gather lists
* multiple namespaces support through a new nvme-ns device
Finally, the series wraps up with changing the PCI vendor and device ID to get
rid of the internal Intel id and as a side-effect get rid of some Linux kernel
quirks that no longer applies.
"pci: pass along the return value of dma_memory_rw" has already been posted by
Philippe in another series, but since it is not applied yet, I am including it
here.
Changes for v2
~~~~~~~~~~~~~~
* Added a new patch ("hw/block/nvme: fix typo in trace event") that does what
it says on the tin.
* Dropped the "hw/block/nvme: support multiple parallel aios per request"
patch (Keith).
* hw/block/nvme: add symbolic command name to trace events
Changed to single quote (Philippe)
* hw/block/nvme: default request status to success
Commit message typo fixed (Philippe)
* hw/block/nvme: change controller pci id
Do NOT bump the device id for the legacy Intel id (David)
