per Intel policy to include file commit date using git cmd
below. The policy does not apply to non-Intel (C) notices.
git log --follow -C90% --format=%ad --date default <file> | tail -1
and then pull just the 4 digit year from the result.
Intel copyrights were not added to files where Intel either had
no contribution ot the contribution lacked substance (ie license
header updates, formatting changes, etc). Contribution date used
"--follow -C95%" to get the most accurate date.
Note that several files in this patch didn't end the license/(c)
block with a blank comment line so these were added as the vast
majority of files do have this last blank line. Simply there for
consistency.

Adds user write throttling - since writing to cache must be balanced
against the ability to compact the data to the base device, this
throttling mechanism allows for a smoother, more stable performance
levels - tying the user write speed to the compaction drain speed.

Adds ability to send trim commands to FTL - only 4MiB aligned requests (both
for offset and length of request) will be processed. During a trim
operation an L2P page (containing 1024 4B entries, 1 per user LBA; which
is where the 4MiB alignment comes from) will be marked as unmapped.
After this point any L2P access to that page will actually set the
entries themselves as FTL_ADDR_INVALID. This is done to make the trim as
fast as possible, since for large requests it's probable that most of
the L2P pages aren't actually in DRAM.

as containing valid (current) user data or not. A clear bit denotes
the location has no valid data and may be skipped during relocation

necessary to do the necessary comparision against L2P).
