When only the keyring module is included but auth is not, modpost
complains about the lack of a module license tag:
ERROR: modpost: missing MODULE_LICENSE() in drivers/nvme/common/nvme-common.o
Address this by making both modules buildable standalone,
removing the now unnecessary CONFIG_NVME_COMMON symbol
in the process.
Also, now that NVME_KEYRING config symbol can be either a module or
built-in, the stubs need to check for '#if IS_ENABLED' rather than a
simple '#ifdef'.
Fixes: 9d77eb5277849 ("nvme-keyring: register '.nvme' keyring")

Implement NVMe-oF In-Band authentication according to NVMe TPAR 8006.
This patch adds two new fabric options 'dhchap_secret' to specify the
pre-shared key (in ASCII respresentation according to NVMe 2.0 section
8.13.5.8 'Secret representation') and 'dhchap_ctrl_secret' to specify
the pre-shared controller key for bi-directional authentication of both
the host and the controller.
Re-authentication can be triggered by writing the PSK into the new
controller sysfs attribute 'dhchap_secret' or 'dhchap_ctrl_secret'.

Add SPDX license identifiers to all Make/Kconfig files which:
- Have no license information of any form
These files fall under the project license, GPL v2 only. The resulting SPDX
license identifier is:

This patch introduces a implementation of NVMe subsystems,
controllers and discovery service which allows to export
NVMe namespaces across fabrics such as Ethernet, FC etc.
The implementation conforms to the NVMe 1.2.1 specification
and interoperates with NVMe over fabrics host implementations.
Configuration works using configfs, and is best performed using
the nvmetcli tool from http://git.infradead.org/users/hch/nvmetcli.git,
which also has a detailed explanation of the required steps in the
README file.

This patch moves the NVMe driver from drivers/block/ to its own new
drivers/nvme/host/ directory. This is in preparation of splitting the
current monolithic driver up and add support for the upcoming NVMe
over Fabrics standard. The drivers/nvme/host/ is chose to leave space
for a NVMe target implementation in addition to this host side driver.
