Decoding an invalid address with certain firmware decoders could
cause a #PF (Page Fault) in the EFI runtime context, which could
subsequently hang the system. To make {i10nm,skx}_edac more robust
against such bogus firmware decoders, filter out invalid addresses
before allowing the firmware decoder to process them.

The eMMC card can be set into write-protected mode to prevent data from
being accidentally modified or deleted. Wp_grp_size (Write Protect Group
Size) refers to an attribute of the eMMC card, used to manage write
protection and is the CSD register [36:32] of the eMMC device. Wp_grp_size
(Write Protect Group Size) indicates how many eMMC blocks are contained in
each write protection group on the eMMC card.
To allow userspace easy access of the CSD register bits, let's add sysfs
node "wp_grp_size".

There is no need to duplicate what SPI core or individual controller
drivers already do, i.e. mapping the buffers for DMA capable transfers.
Note, that the code, besides its redundancy, was buggy: strictly speaking
there is no guarantee, while it's true for those which can use this code
(see below), that the SPI host controller _is_ the device which does DMA.
Also see the Link tags below.
Additional notes. Currently only two SPI host controller drivers may use
premapped (by the user) DMA buffers:
- drivers/spi/spi-au1550.c
- drivers/spi/spi-fsl-spi.c
Both of them have DMA mapping support code. I don't expect that SPI host
controller code is worse than what has been done in mmc_spi. Hence I do
not expect any regressions here. Otherwise, I'm pretty much sure these
regressions have to be fixed in the respective drivers, and not here.
That said, remove all related pieces of DMA mapping code from mmc_spi.

This driver exposes hardware sensors of the Gigabyte AORUS Waterforce
all-in-one CPU liquid coolers, which communicate through a proprietary
USB HID protocol. Report offsets were initially discovered in [1] and
confirmed by me on a Waterforce X240 by observing the sent reports from
the official software.
Available sensors are pump and fan speed in RPM, as well as coolant
temperature. Also available through debugfs is the firmware version.
Attaching a fan is optional and allows it to be controlled from the
device. If it's not connected, the fan-related sensors will report
zeroes.
The addressable RGB LEDs and LCD screen are not supported in this
driver and should be controlled through userspace tools.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

When KASLR is enabled, the KASLR_FLAG bit in boot_params->hdr.loadflags
should be set to 1 to propagate KASLR status from compressed kernel to
kernel, just as the choose_random_location() function does.
Currently, when the kernel is booted via the EFI stub, the KASLR_FLAG
bit in boot_params->hdr.loadflags is not set, even though it should be.
This causes some functions, such as kernel_randomize_memory(), not to
execute as expected. Fix it.

The current driver only has an array of 4 additional L2 unicast
addresses to support the netdev uc address list. Generalize and
expand this infrastructure with an L2 address hash table so we can
support an expanded list of unicast addresses (for bridges,
macvlans, OVS, etc). The L2 hash table infrastructure will also
allow more generalized n-tuple filter support.
This patch creates the bnxt_l2_filter structure and the hash table.
This L2 filter structure has the same bnxt_filter_base structure
as used in the bnxt_ntuple_filter structure.
All currently supported L2 filters will now have an entry in this
new table.
Note that L2 filters may be created for the VF. VF filters should
not be freed when the PF goes down. Add some logic in

The TPS6598x PD controller supports firmware updates that can be loaded
either from an external flash memory or a host using the device's I2C
host interface. This patch implements the second approach, which is
especially relevant if no flash memory is available.
In order to make patch bundle updates, a series of tasks (special
commands) must be sent to the device as it is documented in the
TPS65987DDH and TPS65988DH Host Interface Technical Reference Manual[1],
section 4.11 (Patch Bundle Update Tasks).
The update sequence is as follows:
1. PTCs - Start Patch Load Sequence: the proposed approach includes
device and application configuration data.
2. PTCd - Patch Download: 64-byte data chunks must be sent until the end
of the firmware file is reached (the last chunk may be shorter).
3. PTCc - Patch Data Transfer Complete: ends the patch loading sequence.
After this sequence and if no errors occurred, the device will change
its mode to 'APP' after SETUP_MS milliseconds, and then it will be ready
for normal operation.

The input data passed to execute commands with tps6598x_exec_cmd()
is not supposed to be modified by the function. Moreover, this data is
passed to tps6598x_exec_cmd_tmo() and finally to tps6598x_block_write(),
which expects a const pointer.
The current implementation does not produce any bugs, but it discards
const qualifiers from the pointers passed as arguments. This leads to
compile issues if 'discarded-qualifiers' is active and a const pointer
is passed to the function, which is the case if data from a firmware
structure is passed to execute update commands. Adding the const
modifier to in_data prevents such issues and provides code consistency.

The current implementation includes a number of special cases for the
tps25750. Nevertheless, init and reset functions can be generalized by
adding function pointers to the tipd_data structure in order to offer
that functionality to other parts without additional conditional
clauses.
Some functionality like the cold reset request (GAID) is shared by the
tps25750 and the tps6598x, so they can use the same reset function.

This reverts commit e835c0a4e23c38531dcee5ef77e8d1cf462658c7.
Don't omit soft-reset. During initialization, the driver may need to
perform a soft reset to ensure the phy is ready when the controller
updates the GCTL.PRTCAPDIR or other settings by issuing phy soft-reset.
Many platforms often have access to DCTL register for soft-reset despite
being host-only. If there are actual reported issues from the platforms
that don't expose DCTL registers, then we will need to revisit (perhaps
to teach dwc3 to perform xhci's soft-reset USBCMD.HCRST).
