Title:
  Add hotplug support for Micron's PCIe-SSD devices

Status in The Dell PowerEdge project:
  Confirmed
Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Add hotplug (SRSI) support for Micron's PCIe-SSD devices (mtip32xx
  driver).

  The patches that enable this functionality have been submitted to the
  linux-block mailing list:

  http://marc.info/?l=linux-kernel&m=136812385512296

  Micron has been in direct conversations with Jens Axboe to merge these
  patches upstream, as far as I know there are no objections from the
  community and should just be a matter of time before they are merged
  upstream. They may not land in kernel 3.11, probably looking at 3.12.

  I tested these patches with the 3.10.2 kernel and both hot-removal and
  hot-insertion work ok. I had to pass the pci=pcie_bus_perf kernel
  parameter to avoid MaxPayload issues.

  Adding support in Saucy will pave the way for established support in
  the 14.04 LTS release.
