Since commit ee6d3dd4ed48 ("driver core: make kobj_type constant.")
the driver core allows the usage of const struct kobj_type.
Take advantage of this to constify the structure definition to prevent
modification at runtime.

Flushing system-wide workqueues is dangerous and will be forbidden.
Use a local workqueue in dm-mpath.c, dm-raid1.c, and dm-stripe.c.

Commit acfe0ad74d2e1 ("dm: allocate a special workqueue for deferred
device removal") switched from using system workqueue to a single
workqueue local to DM. But it didn't eliminate the call to
flush_scheduled_work() that was introduced purely for the benefit of
deferred device removal with commit 2c140a246dc ("dm: allow remove to
be deferred").
Since DM core uses its own workqueue (and queue_work) there is no need
to call flush_scheduled_work() from local_exit(). local_exit()'s
destroy_workqueue(deferred_remove_workqueue) handles flushing work
started with queue_work().
Fixes: acfe0ad74d2e1 ("dm: allocate a special workqueue for deferred device removal")

Device mapper sends an uevent when the device is suspended, using the
function set_capacity_and_notify. However, this causes a race condition
with udev.
Udev skips scanning dm devices that are suspended. If we send an uevent
while we are suspended, udev will be racing with device mapper resume
code. If the device mapper resume code wins the race, udev will process
the uevent after the device is resumed and it will properly scan the
device.
However, if udev wins the race, it will receive the uevent, find out that
the dm device is suspended and skip scanning the device. This causes bugs
such as systemd unmounting the device - see
https://bugzilla.redhat.com/show_bug.cgi?id=2158628
This commit fixes this race.
We replace the function set_capacity_and_notify with set_capacity, so that
the uevent is not sent at this point. In do_resume, we detect if the
capacity has changed and we pass a boolean variable need_resize_uevent to
dm_kobject_uevent. dm_kobject_uevent adds "RESIZE=1" to the uevent if
need_resize_uevent is set.

Recently I encountered one case where I cannot increase the MTU size
directly from 1500 to a much bigger value with XDP enabled if the
server is equipped with IXGBE card, which happened on thousands of
servers in production environment. After applying the current patch,
we can set the maximum MTU size to 3K.
This patch follows the behavior of changing MTU as i40e/ice does.

Xilinx PG158 page 80 [1] states that master transaction inhibit bit must
be set to properly setup the transaction in QSPI mode. Add the force_irq
flag to follow this sequence.

Merge series from Dhruva Gole <d-gole@ti.com>:
* Reset the CMD_CTRL Register, without which read/writes in STIG mode
were failing in some cases. The issue came to light while using STIG
Mode for small reads.
* Also add a flag that can allow us to do direct reads but distinguish
direct writes, thus enabling us to disable writes in DAC mode in some
cases that require it. (Like to write to some connected Flash registers)
* Fix register reads in STIG mode and also use STIG mode while reading flash
registers.
Currently if you try to read a register while in STIG mode there is no
support for ADDR and thus naturally a register never gets read from the
flash.
This patch series has been tested on a TI AM625-SK-EVM with both a quad
spi nor flash (s25hs) and OSPI NOR Flash (s28hs).
Output of ltp-ddt test, "DD_RW_ERASESIZE_UBIFS" run with s25hs512t flash:

The Qualcomm PCI bridge device (Device ID 0x010e) found in chipsets such as
SC8280XP used in Lenovo Thinkpad X13s, does not set the Command Completed
bit unless writes to the Slot Command register change "Control" bits.
This results in timeouts like below during boot and resume from suspend:
pcieport 0002:00:00.0: pciehp: Timeout on hotplug command 0x03c0 (issued 2020 msec ago)
...
pcieport 0002:00:00.0: pciehp: Timeout on hotplug command 0x13f1 (issued 107724 msec ago)
Add the device to the Command Completed quirk to mark commands "completed"
immediately unless they change the "Control" bits.
