When vary_offset is set (e.g. test case 3), the offset is not always
zero so memcmpshow() will show the wrong offset in the print message.
To fix this we introduce a new function memcmpshowoffset() which takes
offset as a parameter and displays the right offset and use it in
the case where offset is non zero.
The old memcmpshow() functionality is preserved by converting it into
a macro with offset preset to 0.

Using struct spi_device_id for storing list of flash devices comes from
early SPI NOR framework days. Thanks to the commit 70f3ce0510af ("mtd:
spi-nor: make spi_nor_scan() take a chip type name, not spi_device_id")
we can stop using spi_device_id and just switch to our own struct.

The SPI core currently reports the MODALIAS uevent as "spi:<modalias>"
even for SPI devices that were registered by OF.
That means the OF module alias exported by MODULE_OF_TABLE(of,...) is
currently not used and user-space has no way to autoload this module.
But it is still a good practice to add the OF module alias information
into the kernel module even when it currently is unused so once the SPI
core is changed to report a correct OF modalias uevent, module
autoloading will be working for this driver.

The read ID count should be made as large as the maximum READ_ID size,
so there's no need to have dynamic size. This commit sets the hardware
maximum read ID count, which should be more than enough on all cases.
Also, we get rid of the read_id_bytes, and use a macro instead.

When 2 commands are submitted in a row, and the second is very quick,
the completion of the second command might never come. This happens
especially if the second command is quick, such as a status read after
an erase.
The issue is that in the interrupt handler, the status bits are cleared
after the new command is issued. There is a small temporal window where
this happens :
- the previous command has set the command done bit
- the ready for a command bit is set
- the handler submits the next command
- just then, the command completes, and the command done bit is still
set
- the handler clears the "previous" command done bit
- the handler exits
In this flow, the "command done" of the next command will never trigger
a new interrupt to finish the status command, as it was cleared for both
commands.
Fix this by clearing the status bit before submitting a new command.

When the nand is first probe, and upon the first command start, the
status bits should be cleared before the interrupts are unmasked.
The bug is tricky : if the bootloader left a status bit set, the
unmasking of interrupts does trigger the interrupt handler before the
first command is issued, blocking the good behavior of the nand.
The same would happen if in pxa3xx_nand code flow a status bit is left,
and then a command is started.

When keeping the configuration set by the bootloader (by using
the marvell,nand-keep-config property), the pxa3xx_nand_detect_config()
function is called and set the chunk size to 512 as a default value if
NDCR_PAGE_SZ is not set.
In the other case, when not keeping the bootloader configuration, no
chunk size is set. Fix this by adding a default chunk size of 512.

We found there is a low probability(5%) QSPI access timeout issue,
usually it happened on kernel boot stage, the first time kernel tried to
access QSPI chip. The READ_ID command was sent but not executed,
consequently the probe function failed.
The root cause is that the divider is not glitchless in i.MX6SX chip.
If qspi clock enabled then change clock frequency by call clk_set_rate,
there will be glitch at low possiblity rate and pass to qspi controller.
The controler will be hang by this glitch.
Based on the new clock flag(CLK_SET_RATE_GATE) and new framework, we
need to change the approach of seting clock rate.
1. Disable clock.
2. call clk_set_rate.
3. Enable clock again.

QSPI may failed to map enough memory (256MB) for AHB read in
previous implementation, especially in 3G/1G memory layout kernel.
Dynamically map memory to avoid such issue.
This implementation generally map QUADSPI_MAX_IOMAP (default 4MB) memory
for AHB read, it should be enough for common scenarios, and the side
effect (0.6% performance drop) is minor.

When we added the "jedec,spi-nor" compatible string for use in this
driver, we added it as a modalias option. The modalias can be derived in
different ways for platform devices vs. device tree (of_*) matching. But
for device tree matching (the primary target of this identifier string),
the modalias is determined from the first entry in the 'compatible'
property. IOW, the following properties would bind to this driver:
// Option (a), modalias = "spi-nor"
compatible = "jedec,spi-nor";
// Option (b), modalias = "spi-nor"
compatible = "idontknowwhatimdoing,spi-nor";
But the following would not:
// Option (c), modalias = "shinynewdevice"
compatible = "myvendor,shinynewdevice", "jedec,spi-nor";
So, we'd like to match (a) and (c) (even when we don't have an explicit
entry for "shinynewdevice"), and we'd rather not allow (b).
To do this, we
(1) always (for devices without specific platform data) pass the
modalias to the spi-nor library;
(2) rework the spi-nor library to not reject "bad" names, and
instead just fall back to autodetection; and
(3) add the .of_match_table to properly catch all "jedec,spi-nor".
This allows (a) and (c) without warnings, and rejects (b).

Commit 835a6a2f8603 ("Bluetooth: Stop sabotaging list poisoning")
thought that the code was sabotaging the list poisoning when NULL'ing
out the list pointers and removed it.
But what was going on was that the bluetooth code was using NULL
pointers for the list as a way to mark it empty, and that commit just
broke it (and replaced the test with NULL with a "list_empty()" test on
a uninitialized list instead, breaking things even further).
So fix it all up to use the regular and real list_empty() handling
(which does not use NULL, but a pointer to itself), also making sure to
initialize the list properly (the previous NULL case was initialized
implicitly by the session being allocated with kzalloc())
This is a combination of patches by Marcel Holtmann and Tedd Ho-Jeong
An.

Pull SCSI target updates from Nicholas Bellinger:
"It's been a busy development cycle for target-core in a number of
different areas.
The fabric API usage for se_node_acl allocation is now within
target-core code, dropping the external API callers for all fabric
drivers tree-wide.
There is a new conversion to RCU hlists for se_node_acl and
se_portal_group LUN mappings, that turns fast-past LUN lookup into a
completely lockless code-path. It also removes the original
hard-coded limitation of 256 LUNs per fabric endpoint.
The configfs attributes for backends can now be shared between core
and driver code, allowing existing drivers to use common code while
still allowing flexibility for new backend provided attributes.
The highlights include:
- Merge sbc_verify_dif_* into common code (sagi)
- Remove iscsi-target support for obsolete IFMarker/OFMarker
(Christophe Vu-Brugier)
- Add bidi support in target/user backend (ilias + vangelis + agover)
- Move se_node_acl allocation into target-core code (hch)
- Add crc_t10dif_update common helper (akinobu + mkp)
- Handle target-core odd SGL mapping for data transfer memory
(akinobu)
- Move transport ID handling into target-core (hch)
- Move task tag into struct se_cmd + support 64-bit tags (bart)
- Convert se_node_acl->device_list[] to RCU hlist (nab + hch +
