7127f0a742 net: lwm2m: Notify the application on network error
Add a simple backoff mechanism between consecutive registration attempts
in case of registration failures. Finally, notify the application in
case the registration failed several times.

397b2a71fa net: lwm2m: Add a callback to notify socket errors to engine users
Currently, when socket errors occur during receive, the LwM2M engine
restarts the state machine and registers again to the server. While this
works in simple use case (only RD client socket open), it's not a valid
approach when more sockets are open (FW update socket).

Fix this by introducing socket fault callback, which is registered by
the LwM2M engine users. This way, a proper socket owner is notified on
error and can pertake appropriate action.

For RD socket errors the behaviour remains the same - the state machine
is reset and the client registers again to the server. For FW update
socket, handle the error by reopening the socket and retransmitting the
last request. This allows to resume the download from the point the
error occured, w/o a need to start from scratch.

d2a72273b7 x86: add support for common page tables
We provide an option for low-memory systems to use a single set
of page tables for all threads. This is only supported if
KPTI and SMP are disabled. This configuration saves a considerable
amount of RAM, especially if multiple memory domains are used,
at a cost of context switching overhead.

Some caching techniques are used to reduce the amount of context
switch updates; the page tables aren't updated if switching to
a supervisor thread, and the page table configuration of the last
user thread switched in is cached.

b8242bff64 x86: move page tables to the memory domain level
- z_x86_userspace_enter() for both 32-bit and 64-bit now
  call into C code to clear the stack buffer and set the
  US bits in the page tables for the memory range.

- Page tables are now associated with memory domains,
  instead of having separate page tables per thread.
  A spinlock protects write access to these page tables,
  and read/write access to the list of active page
  tables.

- arch_mem_domain_init() implemented, allocating and
  copying page tables from the boot page tables.

- struct arch_mem_domain defined for x86. It has
  a page table link and also a list node for iterating
  over them.

941322c49e userspace: document multiple mem domain init calls
k_mem_domain objects should not be initialized multiple times,
there's no support for memory domain life-cycles or freeing
memory that an arch_mem_domain_init() may have allocated.
Clearly document this.

The init function has to assume the provided domain is un-
initialized memory so it's not possible to robustly check
for this; a note is left in the arch_ definition to add an
assertion if feasible.

It's really unsafe to call an init function on any kernel
object more than once, but in this particular case if the
memory domain initialization resulted in the creation of
page tables or linked data structures really bad things can
happen. Currently no arch implements arch_mem_domain_init()
yet, but this is changing soon for x86.

One test case currently does this, it will be fixed in
a forthcoming patch.

eca0141152 Bluetooth: Mesh: Isolate cryptographic material
This is a major refactoring of the handling of the cryptographic
material of both the network and transport layers. The aim is to
encapsulate the key object manipulation, and improve overall modularity.

Pulls Applications and Subnets out of the bt_mesh and into separate
modules, with static storage types on the data. This has several
side-effects:
- The Config Server no longer operates directly on the bt_mesh.subs and
  bt_mesh.apps lists, but goes through a public configuration interface,
  following the pattern set in #27908.
- All iteration through the keys is done through iteration APIs
- Key resolution on RX and TX is centralized.
- Changes to the keys triggers events the other modules can register
  handlers for.
- Friendship credentials are stored in the lpn and friend structures.

f6d32ab0a4 kernel: Add cache coherence management framework
Zephyr SMP kernels need to be able to run on architectures with
incoherent caches.  Naive implementation of synchronization on such
architectures requires extensive cache flushing (e.g. flush+invalidate
everything on every spin lock operation, flush on every unlock!) and
is a performance problem.

Instead, many of these systems will have access to separate "coherent"
(usually uncached) and "incoherent" regions of memory.  Where this is
available, place all writable data sections by default into the
coherent region.  An "__incoherent" attribute flag is defined for data
regions that are known to be CPU-local and which should use the cache.
By default, this is used for stack memory.

Stack memory will be incoherent by default, as by definition it is
local to its current thread.  This requires special cache management
on context switch, so an arch API has been added for that.

Also, when enabled, add assertions to strategic places to ensure that
shared kernel data is indeed coherent.  We check thread objects, the
_kernel struct, waitq's, timeouts and spinlocks.  In practice almost
all kernel synchronization is built on top of these structures, and
any shared data structs will contain at least one of them.

Existing openthread_api_mutex_lock()/unlock() functions are

require a non-blocking version of the former for less critical

Add openthread_api_mutex_try_lock() which never waits and
exits immediately if the mutex is held by another thread.

8165008f44 dts: remove legacy macro support
The legacy macros were first deprecated in Zephyr v2.3. Now that
Zephyr v2.4 has been released, that makes two releases where these
macros have been deprecated, so it's OK to remove them.

This leaves support for legacy binding syntax in place. Removing that
is left to future work.

We need to update various pieces of documentation related to flash
partitions that never got updated when the new API was introduced.
Consolidate this information in the flash_map.h API reference page,
since that's really where users will run into it. This also gives us
the opportunity to improve this documentation.

Adjust a couple of kconfigfunctions.py and sanitycheck bits to use
non-legacy edtlib APIs.

Adding dictionary commands concept. It simplifies creation of multiple
commands that are handled by a one function handler.

This is a special kind of static commands. Dictionary commands can be
used every time you want to use a pair: (string <-> corresponding data)
in a command handler. The string is usually a verbal description
of a given data. The idea is to use the string as a command syntax that
can be prompted by the shell and corresponding data can be used to
