The literal blocks in this file lacked the necessary blank line at the top,

/Documentation/ABI/testing/sysfs-bus-nvdimm:11: WARNING: Unexpected indentation.

Add the lines it's longing for and bring about a bit of warning peace.

cxl/pmem: add id attribute to CXL based nvdimm

Add an id group attribute for CXL based nvdimm object. The addition allows
ndctl to display the "unique id" for the nvdimm. The serial number for the
CXL memory device will be used for this id.

[
{
"dev":"nmem10",
"id":"0x4",
"security":"disabled"
},
]

The id attribute is needed by the ndctl security key management to setup a
keyblob with a unique file name tied to the mem device.

PM, libnvdimm: Add runtime firmware activation support

Abstract platform specific mechanics for nvdimm firmware activation
behind a handful of generic ops. At the bus level ->activate_state()
indicates the unified state (idle, busy, armed) of all DIMMs on the bus,
and ->capability() indicates the system state expectations for activate.
At the DIMM level ->activate_state() indicates the per-DIMM state,
->activate_result() indicates the outcome of the last activation
attempt, and ->arm() attempts to transition the DIMM from 'idle' to
'armed'.

A new hibernate_quiet_exec() facility is added to support firmware
activation in an OS defined system quiesce state. It leverages the fact
that the hibernate-freeze state wants to assert that a memory
hibernation snapshot can be taken. This is in contrast to a platform
firmware defined quiesce state that may forcefully quiet the memory
controller independent of whether an individual device-driver properly
supports hibernate-freeze.

The libnvdimm sysfs interface is extended to support detection of a
firmware activate capability. The mechanism supports enumeration and
triggering of firmware activate, optionally in the
hibernate_quiet_exec() context.
