From: Klaus Jensen <k.jensen@samsung.com>
The size of the BAR is 0x1000 (main registers) + 8 bytes for each
queue. Currently, the size of the BAR is calculated like so:
n->reg_size = pow2ceil(0x1004 + 2 * (n->num_queues + 1) * 4);
Since the 'num_queues' parameter already accounts for the admin queue,
this should in any case not need to be incremented by one. Also, the
size should be initialized to (0x1000).
n->reg_size = pow2ceil(0x1000 + 2 * n->num_queues * 4);
This, with the default value of num_queues (64), we will set aside room
for 1 admin queue and 63 I/O queues (4 bytes per doorbell, 2 doorbells
per queue).

Change the prefix of all nvme device related trace events to 'pci_nvme'
to not clash with trace events from the nvme block driver.

Pull the controller memory buffer check to its own function. The check
will be used on its own in later patches.

The num_queues device paramater has a slightly confusing meaning because
it accounts for the admin queue pair which is not really optional.
Secondly, it is really a maximum value of queues allowed.
Add a new max_ioqpairs parameter that only accounts for I/O queue pairs,
but keep num_queues for compatibility.

Why not splitting this in 2 trivial patches? The easiest a patch is to
review, the less likely bug can be missed. Here I'm scrolling over 2

to manually edit and re-do your patch.
