When hardware is in resetting stage, we may can't poll back all the
expected work completions as the hardware won't generate cqe anymore.
This patch allows the driver to compose the expected wc instead of the
hardware during resetting stage. Once the hardware finished resetting, we
can poll cq from hardware again.

The rdma_user_mmap_io interface created a common interface for drivers to
correctly map hw resources and zap them once the ucontext is destroyed
enabling the drivers to safely free the hw resources.
However, this meant the drivers need to delay freeing the resource to the
ucontext destroy phase to ensure they were no longer mapped. The new
mechanism for a common way of handling user/driver address mapping enabled
notifying the driver if all umap_priv mappings were removed, and enabled
freeing the hw resources when they are done with and not delay it until
ucontext destroy.
Since not all drivers use the mechanism, NULL can be sent to the
rdma_user_mmap_io interface to continue working as before. Drivers that
use the mmap_xa interface can pass the entry being mapped to the
rdma_user_mmap_io function to be linked together.

This is not the first attempt to fix building random configurations,

a3e2d4c7e766 ("RDMA/hns: remove obsolete Kconfig comment") to get back to
the previous state, then fix the issues described there differently, by
adding more specific dependencies: INFINIBAND_HNS can now only be built-in
if at least one of HNS or HNS3 are built-in, and the individual back-ends
are only available if that code is reachable from the main driver.

The parameters npages used to initial mtt of srq->idx_que shouldn't be
same with srq's. And page_shift should be calculated from idx_buf_pg_sz.
This patch fixes above issues and use field named npage and page_shift
in hns_roce_buf instead of two temporary variables to let us use them
anywhere.

Pull LED updates from Jacek Anaszewski:
"In this cycle we've finally managed to contribute the patch set
sorting out LED naming issues. Besides that there are many changes
scattered among various LED class drivers and triggers.
LED naming related improvements:
- add new 'function' and 'color' fwnode properties and deprecate
'label' property which has been frequently abused for conveying
vendor specific names that have been available in sysfs anyway
- introduce a set of standard LED_FUNCTION* definitions
- introduce a set of standard LED_COLOR_ID* definitions
- add a new {devm_}led_classdev_register_ext() API with the
capability of automatic LED name composition basing on the
properties available in the passed fwnode; the function is
backwards compatible in a sense that it uses 'label' data, if
present in the fwnode, for creating LED name
- add tools/leds/get_led_device_info.sh script for retrieving LED
vendor, product and bus names, if applicable; it also performs
basic validation of an LED name
- update following drivers and their DT bindings to use the new LED
registration API:
- leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114,
leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-blt
Other LED class improvements:
- replace {devm_}led_classdev_register() macros with inlines
- allow to call led_classdev_unregister() unconditionally
- switch to use fwnode instead of be stuck with OF one
LED triggers improvements:
- led-triggers:
- fix dereferencing of null pointer
- fix a memory leak bug
- ledtrig-gpio:
- GPIO 0 is valid
Drop superseeded apu2/3 support from leds-apu since for apu2+ a newer,
more complete driver exists, based on a generic driver for the AMD
SOCs gpio-controller, supporting LEDs as well other devices:
- drop profile field from priv data
- drop iosize field from priv data
- drop enum_apu_led_platform_types
- drop superseeded apu2/3 led support
- add pr_fmt prefix for better log output
- fix error message on probing failure
Other misc fixes and improvements to existing LED class drivers:
- leds-ns2, leds-max77650:
- add of_node_put() before return
- leds-pwm, leds-is31fl32xx:
- use struct_size() helper
- leds-lm3697, leds-lm36274, leds-lm3532:
- switch to use fwnode_property_count_uXX()
- leds-lm3532:
- fix brightness control for i2c mode
- change the define for the fs current register
- fixes for the driver for stability
- add full scale current configuration
- dt: Add property for full scale current.
- avoid potentially unpaired regulator calls
- move static keyword to the front of declarations
- fix optional led-max-microamp prop error handling
- leds-max77650:
- add of_node_put() before return
- add MODULE_ALIAS()
- Switch to fwnode property API
- leds-as3645a:
- fix misuse of strlcpy
- leds-netxbig:
- add of_node_put() in netxbig_leds_get_of_pdata()
- remove legacy board-file support
- leds-is31fl319x:
- simplify getting the adapter of a client
- leds-ti-lmu-common:
- fix coccinelle issue
- move static keyword to the front of declaration
- leds-syscon:
- use resource managed variant of device register
- leds-ktd2692:
- fix a typo in the name of a constant
- leds-lp5562:
- allow firmware files up to the maximum length
- leds-an30259a:
- fix typo
- leds-pca953x:
- include the right header"

There are two modes for mailbox command (cmd) queue, i.e., event mode and
poll mode. For each mode, we use corresponding semaphores to protect the
cmd queue resource competition, so called event_sem and poll_sem. During
cmd init, both semaphores are initialized and poll mode is selected.
Thus, there is no need to up poll_sema again in cmd_use_polling.
Furthermore, there is no need to down the sema of the other side while
switching mode. This patch aims to decouple the switch between event mode
and poll mode of cmd.
