Add support for freeze security on Intel nvdimm. This locks out any
changes to security for the DIMM until a hard reset of the DIMM is
performed. This is triggered by writing "freeze" to the generic
nvdimm/nmemX "security" sysfs attribute.

Some NVDIMMs, like the ones defined by the NVDIMM_FAMILY_INTEL command
set, expose a security capability to lock the DIMMs at poweroff and
require a passphrase to unlock them. The security model is derived from
ATA security. In anticipation of other DIMMs implementing a similar
scheme, and to abstract the core security implementation away from the
device-specific details, introduce nvdimm_security_ops.
Initially only a status retrieval operation, ->state(), is defined,
along with the base infrastructure and definitions for future
operations.

The generated dimm id is needed for the sysfs attribute as well as being
used as the identifier/description for the security key. Since it's
constant and should never change, store it as a member of struct nvdimm.
As nvdimm_create() continues to grow parameters relative to NFIT driver
requirements, do not require other implementations to keep pace.
Introduce __nvdimm_create() to carry the new parameters and keep
nvdimm_create() with the long standing default api.

Avoid expensive indirect calls in the fast path DMA mapping

While the dma-direct code is (relatively) clean and simple we actually
have to use the swiotlb ops for the mapping on many architectures due
to devices with addressing limits. Instead of keeping two
implementations around this commit allows the dma-direct
implementation to call the swiotlb bounce buffering functions and
thus share the guts of the mapping implementation. This also
simplified the dma-mapping setup on a few architectures where we
don't have to differenciate which implementation to use.

Instead of providing a special dma_mark_clean hook just for ia64, switch
ia64 to use the normal arch_sync_dma_for_cpu hooks instead.
This means that we now also set the PG_arch_1 bit for pages in the
swiotlb buffer, which isn't stricly needed as we will never execute code
out of the swiotlb buffer, but otherwise harmless.

The dummy DMA ops are currently used by arm64 for any device which has
an invalid ACPI description and is thus barred from using DMA due to not
knowing whether is is cache-coherent or not. Factor these out into
general dma-mapping code so that they can be referenced from other
common code paths. In the process, we can prune all the optional
callbacks which just do the same thing as the default behaviour, and
fill in .map_resource for completeness.

Some interrupt controllers use separate bits for controlling rising
and falling edge interrupts in the mask register i.e. they have one
interrupt for rising edge and one for falling.
We already handle the case where we have a single interrupt in the
mask register and a separate type configuration register.
Add a new switch to regmap_irq_chip which tells the framework to use
the mask_base address for configuring the edge of the interrupts that
define type_falling/rising_mask values.
For such interrupts we never update the type_base bits. For interrupts
that don't define type masks or their regmap irq chip doesn't set the
type_in_mask to true everything stays the same.

MRPC normal mode requires the host to read the MRPC command status and
output data from BAR. This results in high latency responses from the
Memory Read TLP and potential Completion Timeout (CTO).
Add support for MRPC DMA mode, including related macro definitions and data
structures and code to:
* Retrieve MRPC DMA mode version from adapter firmware
* Allocate DMA buffer, register ISR, and enable DMA during init
* Check MRPC execution status and get execution results from DMA buffer
* Release DMA buffer and disable DMA function when unloading module
MRPC DMA mode is a new feature of firmware, and the driver will fall back
to MRPC normal mode if there is no support in the legacy firmware.
Add a module parameter, "use_dma_mrpc", to select between MRPC DMA mode and
MRPC normal mode. Since the driver automatically detects DMA support in
the firmware, this parameter is just for debugging and testing.
Include <linux/io-64-nonatomic-lo-hi.h> so that readq/writeq is replaced by
two readl/writel on systems that do not support it.

Two threads can try to fire the irq_sim with different offsets and will
end up fighting for the irq_work asignment. Thomas Gleixner suggested a
solution based on a bitfield where we set a bit for every offset
associated with an interrupt that should be fired and then iterate over
all set bits in the interrupt handler.
This is a slightly modified solution using a bitmap so that we don't
impose a limit on the number of interrupts one can allocate with
irq_sim.

Since the addition of platform MSI support, there were two helpers
supposed to allocate/free IRQs for a device:
platform_msi_domain_alloc_irqs()
platform_msi_domain_free_irqs()
In these helpers, IRQ descriptors are allocated in the "alloc" routine
while they are freed in the "free" one.
Later, two other helpers have been added to handle IRQ domains on top
of MSI domains:
platform_msi_domain_alloc()
platform_msi_domain_free()
Seen from the outside, the logic is pretty close with the former
helpers and people used it with the same logic as before: a
platform_msi_domain_alloc() call should be balanced with a
platform_msi_domain_free() call. While this is probably what was
intended to do, the platform_msi_domain_free() does not remove/free
the IRQ descriptor(s) created/inserted in
platform_msi_domain_alloc().
One effect of such situation is that removing a module that requested
an IRQ will let one orphaned IRQ descriptor (with an allocated MSI
entry) in the device descriptors list. Next time the module will be
inserted back, one will observe that the allocation will happen twice
in the MSI domain, one time for the remaining descriptor, one time for
the new one. It also has the side effect to quickly overshoot the
maximum number of allocated MSI and then prevent any module requesting
an interrupt in the same domain to be inserted anymore.
This situation has been met with loops of insertion/removal of the
mvpp2.ko module (requesting 15 MSIs each time).

different types.
For each sublist encountered, the function pointed to by the
get_handler_for_guid argument is called with the type specifier GUID and
returns either a pointer to a function to handle elements of that type or
NULL if the type is not of interest.
If the sublist is of interest, each element is passed to the handler

Between v3 [1] and v4 [2] of the blkg association series, the
association point moved from generic_make_request_checks(), which is
called after the request enters the queue, to bio_set_dev(), which is when
the bio is formed before submit_bio(). When the request_queue goes away,
the blkgs supporting the request_queue are destroyed and then the
q->root_blkg is set to %NULL.
This patch adds a %NULL check to blkg_tryget_closest() to prevent the
NPE caused by the above. It also adds a guard to see if the
request_queue is dying when creating a blkg to prevent creating a blkg
for a dead request_queue.

So it looks like folks are interested in dwc3 again. Almost 64% of the

functions and dwc2.
There are two important parts here: a. removal of the waitqueue from
dwc3's dequeue implementation, which will guarantee that gadget
functions can dequeue from any context and; b. better method for
starting isochronous transfers to avoid, as much as possible, missed

The API to configure a PWM using pwm_enable(), pwm_disable(),
pwm_config() and pwm_set_polarity() is superseeded by atomically setting
the parameters using pwm_apply_state(). To get forward with deprecating
the former set of functions use the opportunity that there is no current
user of pwm_set_polarity() and remove it.

Kishon writes:
phy: for 4.21
*) Change phy set_mode ops to take both mode and setmode as arguments
*) Add phy_configure() and phy_validate() API's mostly used for MIPI D-PHY
*) Add helpers to get default values of parameters define in MIPI D-PHY spec
*) Add driver for TI's CPSW Port PHY Interface Mode selection
*) Add driver for Cadence Sierra PHY used with USB and PCIe
*) Add driver for Freescale i.MX8MQ USB3 PHY
*) Fixes QMP PHY bindings to allow the clocks provided by the PHY to be
pointed at in device tree
*) Fix for using fully specified regions (in device tree) for configuring
the second lane in dual lane PHYs in QMP PHY
*) Add support for Allwinner H6 USB2 PHY in phy-sun4i-usb driver
*) Update phy-rcar-gen3-usb driver to follow the hardware manual
*) Add support for fine grained power management in mapphone-mdm6600 driver

The MIPI D-PHY spec defines default values and boundaries for most of the
parameters it defines. Introduce helpers to help drivers get meaningful
values based on their current parameters, and validate the boundaries of
these parameters if needed.
