Make most AST handlers dynamically registered. This allows to have
subsystem-specific handler source located in the subsystem files,
instead of making subr_trap.c aware of it. For instance, signal
delivery code on return to userspace is now moved to kern_sig.c.
Also, it allows to have some handlers designated as the cleanup (kclear)
type, which are called both at AST and on thread/process exit. For
instance, ast(), exit1(), and NFS server no longer need to be aware
about UFS softdep processing.
The dynamic registration also allows third-party modules to register AST
handlers if needed. There is one caveat with loadable modules: the
code does not make any effort to ensure that the module is not unloaded
before all threads processed through AST handler in it. In fact, this
is already present behavior for hwpmc.ko and ufs.ko. I do not think it
is worth the efforts and the runtime overhead to try to fix it.

While working on new and updates to drivers more structs, fields,
functions, .. were found, had to be shuffled around, ..
Some of these are (so far still dummy) functions or not properly
typed fields. The IEEE80211_HE_ constants are all still dummy.
This was msotly as a start to make new (out-of-tree) things compile.

Move pm_message_t from kernel.h to pm.h and remove a private define
in usb.h as well as adjust the implementation in linux_usb.c.
This cleans up what I believe to be a historic shortcut and is
needed for future wireless driver updates.
Leave a note in UPDATING that drm-kmod users need to update to the
latest version before re-compiling a new kernel to avoid errors

Linux has two defines to check dmi data. DMI_MATCH checks if the dmi
string includes substr. DMI_EXACT_MATCH checks if the dmi string exactly
matches substr. Compat layer should have the same behaviour.
The new definition of dmi_strmatch shouldn't break any driver. A driver
would break if it uses the highest bit of the slot field. Nevertheless,
linux uses the same definition and FreeBSD uses dmi_field values as slot
which are lower than 128.

Working on an update for rtw88 baed on wireless-testing I ran into
a build issue with struct ieee802211_sta. Some fields were factored
out into their own struct apparently preparing for MLO (Multi Link
Operation).
In order to be able to update one driver we have to adjust both
rtw88 and iwlwifi (and the ones still out-of-tree) now.
This is mostly a sed-replace job and no functional changes are
intended.

Kthread worker is a single thread workqueue which can be used in cases
where specific kthread association is necessary, for example, when it
should have RT priority or be assigned to certain cgroup.
This change implements Linux v4.9 interface which mostly hides kthread
internals from users thus allowing to use ordinary taskqueue(9) KPI.
As kthread worker prohibits enqueueing of already pending or canceling
tasks some minimal changes to taskqueue(9) were done.
taskqueue_enqueue_flags() was added to taskqueue KPI which accepts extra
flags parameter. It contains one or more of the following flags:
TASKQUEUE_FAIL_IF_PENDING - taskqueue_enqueue_flags() fails if the task
is already scheduled to execution. EEXIST is returned and the
ta_pending counter value remains unchanged.
TASKQUEUE_FAIL_IF_CANCELING - taskqueue_enqueue_flags() fails if the
task is in the canceling state and ECANCELED is returned.
