The "NVDIMM Block Window Driver Writer's Guide":
http://pmem.io/documents/NVDIMM_DriverWritersGuide-July-2016.pdf
...defines the layout of the block window status register. For the July
2016 version of the spec linked to above, this happens in Figure 4 on
page 26.
The only bits defined in this spec are bits 31, 5, 4, 2, 1 and 0. The
rest of the bits in the status register are reserved, and there is a
warning following the diagram that says:
Note: The driver cannot assume the value of the RESERVED bits in the
status register are zero. These reserved bits need to be masked off, and
the driver must avoid checking the state of those bits.
This change ensures that for hardware implementations that set these
reserved bits in the status register, the driver won't incorrectly fail the
block I/Os.

To be able to generate shared descriptors for AEAD, the authentication size
needs to be known. However, there is no imposed order of calling .setkey,
.setauthsize callbacks.
Thus, in case authentication size is not known at .setkey time, defer it
until .setauthsize is called.
The authsize != 0 check was incorrectly removed when converting the driver

There are a few things missed by the conversion to the
new AEAD interface:
1 - echainiv(authenc) encrypt shared descriptor
The shared descriptor is incorrect: due to the order of operations,
at some point in time MATH3 register is being overwritten.
2 - buffer used for echainiv(authenc) encrypt shared descriptor
Encrypt and givencrypt shared descriptors (for AEAD ops) are mutually
exclusive and thus use the same buffer in context state: sh_desc_enc.
However, there's one place missed by s/sh_desc_givenc/sh_desc_enc,
leading to errors when echainiv(authenc(...)) algorithms are used:
DECO: desc idx 14: Header Error. Invalid length or parity, or
certain other problems.
While here, also fix a typo: dma_mapping_error() is checking
for validity of sh_desc_givenc_dma instead of sh_desc_enc_dma.

if two string compare equal the clcle instruction will update the
string addresses to point _after_ the string. This might already
be on a different page, so we should not use these pointer to

The return value of memcmp does not need the difference, we
can just reuse the condition code and return for CC=1 (All bytes
compared, first operand low) -1 and for CC=2 (All bytes compared,
first operand high) +1
strstr also does not need the diff.

Currently, the ports as seen from the rear number as:
eth0 sfp lan5 lan4 lan3 lan2 lan1 lan6
which is illogical - this came about because the rev 2.0 boards have the
LEDs on the front for the DSA switch (lan5-1) reversed. Rev 2.1 boards
fixed the LED issue, and the Clearfog case numbers the lan ports
increasing from left to right.
Maintaining this illogical numbering causes confusion, with reports that
"my link isn't coming up" and "my connection negotiates 10base-Half"
both of which are due to people thinking that the port next to the SFP
is lan1.
Fix this by renumbering the ports to match people's expectations.

This is not correct, and introduce a race codition:

lock(exp_lock) -

re-activate timer!! waiting exp_lock...

So when the timer expires again, we will access the memory that
