[Patchv2 0/3] NVMe: Introduce CMB allocation scheme

[Jon Derrick]

This set is a continuation of v1 introduced in December [1].
v1 was missing the controls to reduce the queue depth, and so would
allow tags to be issued above the depth of the CMB allocated queues.

v2 drops patch 3 of v1 which created a cmb_resources file with a layout
similar to the pci_dev resource file.

This set was tested with QEMU with NVMe device emulation [2]

Applies to Jen's for-4.6/drivers [3]
