Commit d35df77707bf ("mtd: spi-nor: winbond: fix w25q128 regression")
upstream fixed a regression for flavors of 0xef4018 flash that don't
define SFDP tables. Add a comment on the flash definition highlighting
that there are flavors of flashes with and without SFDP support.
It spares developers searching the entire git log for when we'll better
handle these cases.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/mtd to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

'struct nand_ecc_engine_ops' are not modified in these drivers.
Constifying this structure moves some data to a read-only section, so
increases overall security, especially when the structure holds some
function pointers.
Update the prototype of mxic_ecc_get_pipelined_ops() accordingly.

The last 4 characters in Winbond's branding indicate:
- the package type (ZE/SF/TB),
- the temperature grade (I/J),
- special options, typically the continuous read vs. page read feature
support and its default (G/T/F/R),
None of these information impact us, at the software level (well, the
continuous read mode by default is impacting, but is already handled
gracefully by disabling it in the initialization phase), so let's get
rid of it.

These four chips:
* W25N512GW
* W25N01GW
* W25N01JW
* W25N02JW
all require a single bit of ECC strength and thus feature an on-die
Hamming-like ECC engine. There is no point in filling a ->get_status()
callback for them because the main ECC status bytes are located in
standard places, and retrieving the number of bitflips in case of
corrected chunk is both useless and unsupported (if there are bitflips,
then there is 1 at most, so no need to query the chip for that).
Without this change, a kernel warning triggers every time a bit flips.

The pmecc "user" structure is allocated in atmel_pmecc_create_user() and
was supposed to be freed with atmel_pmecc_destroy_user(), but this other
helper is never called. One solution would be to find the proper
location to call the destructor, but the trend today is to switch to
device managed allocations, which in this case fits pretty well.
Replace kzalloc() by devm_kzalloc() and drop the destructor entirely.

Add manufacturer ID 0xc2 at the end of ID table to allow manufacturer
fixups to be applied for any Macronix flash. This spares us of adding
new flash entries for flashes that can be initialized solely based on
the SFDP data, but still need the manufacturer hooks to set parameters
that can't be discovered at SFDP parsing time.
The ID is added in order to set the octal DTR methods. SFDP defines a
"Command Sequences to Change to Octal DDR (8D-8D-8D) Mode" which can
enable the octal DTR mode. Until that is parsed and used, use the
local defined method.

Parse BFPT in order to retrieve the byte order in 8D-8D-8D mode.
This info flag will be used as a basis to determine whether
there is byte swapping of data for SPI NOR flash in octal
DTR mode.
The controller driver will check whether byte swapping is supported
to determine whether the corresponding operation are supported,
thus avoiding the generation of unexpected data order.

Macronix swaps bytes on a 16-bit boundary when configured in Octal DTR.
The byte order of 16-bit words is swapped when read or written in 8D-8D-8D
mode compared to STR modes. Allow operations to specify the byte order in
DTR mode, so that controllers can swap the bytes back at run-time to
address the flash's endianness requirements, if they are capable. If the
controller is not capable of swapping the bytes, the protocol is downgrade
via spi_nor_spimem_adjust_hwcaps(). When available, the swapping of the
bytes is always done regardless if it's a data or register access, so that
it comply with the JESD216 requirements: "Byte order of 16-bit words is
swapped when read in 8D-8D-8D mode compared to 1-1-1".

Create Macronix specify method for enable Octal DTR mode and
set 20 dummy cycles to allow running at the maximum supported
frequency for Macronix Octal flash.
Use number of dummy cycles which is parse by SFDP then convert
it to bit pattern and set in CR2 register.
Set CR2 register for enable octal DTR mode.
Use Read ID to confirm that enabling/disabling octal DTR mode
was successful.
Macronix ID format is A-A-B-B-C-C in octal DTR mode.
To ensure the successful enablement of octal DTR mode, confirm
that the 6-byte data is entirely correct.

Some SPI-NOR flash swap the bytes on a 16-bit boundary when
configured in Octal DTR mode. It means data format D0 D1 D2 D3
would be swapped to D1 D0 D3 D2. So that whether controller
support swapping bytes should be checked before enable Octal
DTR mode. Add swap byte support on a 16-bit boundary when
configured in Octal DTR mode for Macronix xSPI host controller
driver.
According dtr_swab in operation to enable/disable Macronix
xSPI host controller swap byte feature.
To make sure swap byte feature is working well, program data in
1S-1S-1S mode then read back and compare read data in 8D-8D-8D
mode.
This feature have been validated on byte-swap flash and
non-byte-swap flash.
Macronix xSPI host controller bit "HC_CFG_DATA_PASS" determine
the byte swap feature disabled/enabled and swap byte feature is
working on 8D-8D-8D mode only.

There are NOR flashes (Macronix) that swap the bytes on a 16-bit
boundary when configured in Octal DTR mode. The byte order of
16-bit words is swapped when read or written in Octal Double
Transfer Rate (DTR) mode compared to Single Transfer Rate (STR)
modes. If one writes D0 D1 D2 D3 bytes using 1-1-1 mode, and uses
8D-8D-8D SPI mode for reading, it will read back D1 D0 D3 D2.
Swapping the bytes may introduce some endianness problems. It can
affect the boot sequence if the entire boot sequence is not handled
in either 8D-8D-8D mode or 1-1-1 mode. Therefore, it is necessary
to swap the bytes back to ensure the same byte order as in STR modes.
Fortunately there are controllers that could swap the bytes back at
runtime, addressing the flash's endianness requirements. Provide a
way for the upper layers to specify the byte order in Octal DTR mode.
Merge Tudor's patch and add modifications for suiting newer version
of Linux kernel.

conditionally:
#if IS_ENABLED(CONFIG_KVM_INTEL) || IS_ENABLED(CONFIG_KVM_AMD)
void cpu_emergency_register_virt_callback(cpu_emergency_virt_cb *callback);

Fix the build by defining empty helper functions the same way the old
cpu_emergency_disable_virtualization() function was dealt with for the
same situation.
Maybe we could instead have made the call sites conditional, since the
callers (kvm_arch_{en,dis}able_virtualization()) have an empty weak
fallback. I'll leave that to the kvm people to argue about, this at
least gets the build going for that particular config.

The isomorphism neg_if_exp negates the test of a ?: conditional,
making it unnecessary to have an explicit case for a negated test
with the branches inverted.
At the same time, we can disable neg_if_exp in cases where a
different API function may be more suitable for a negated test.
Finally, in the non-patch cases, E matches an expression with
parentheses around it, so there is no need to mention ()
explicitly in the pattern. The () are still needed in the patch
cases, because we want to drop them, if they are present.

This was added to avoid double-counting accounting keys in journal
replay. But applied incorrectly (easily done since it applies to the
transaction commit, not a particular update), it leads to skipping
in-mem accounting for real accounting updates, and failure to give them
