A loop in k_mem_pool_alloc() around z_sys_mem_pool_block_alloc() assumes
the later may return -EAGAIN with an elaborate comment about it. But
-EAGAIN is no longer returned by that function since commit 7845e1b01e
("lib/mempool: Fix spurious -ENOMEM due to agressive latency control").

This patch is a preparatory step in enabling the MMU in
long mode; no steps are taken to implement long mode support.
We introduce struct x86_page_tables, which represents the
top-level data structure for page tables:
- For 32-bit, this will contain a four-entry page directory
pointer table (PDPT)
- For 64-bit, this will (eventually) contain a page map level 4
table (PML4)
In either case, this pointer value is what gets programmed into
CR3 to activate a set of page tables. There are extra bits in
CR3 to set for long mode, we'll get around to that later.
This abstraction will allow us to use the same APIs that work
with page tables in either mode, rather than hard-coding that
the top level data structure is a PDPT.
z_x86_mmu_validate() has been re-written to make it easier to
add another level of paging for long mode, to support 2MB
PDPT entries, and correctly validate regions which span PDPTE
entries.
Some MMU-related APIs moved out of 32-bit x86's arch.h into
mmustructs.h.

Use PCRE options to make the kernel timeout API identifier rule more

Use rule extends and depends clauses, and pattern disjunction, to

Hint that using --include-headers may be helpful (some patterns can be

Fix for possible Tx Buffer leak during disconnection when
the buffers are in ULL context and not yet enqueued towards
LLL context.
Signed-off-by: Vinayak Kariappa Chettimada <vich@nordicsemi.no>
When more than one simultaneous connections are active,
transmitting data packets to peer, a termination causes
host to use the flushed pending number of completed packets
count for other active connections. This is on reception
of HCI disconnection complete event. But the controller has
not yet released any of the pending enqueued Tx buffers
which was happening after the disconnection event was
dispatched to HCI layer.
The fix here is to dispatch the disconnection complete event
from the LLL context after pending Tx buffers have been
flushed and the buffers get returned to Tx pool in the ULL
context. This way buffers are in the Tx pool before host
get to process the disconnection complete event.

Randomly generating ID the first time coap_next_id() is called is more
in accordance with CoAP recommendations (see
https://tools.ietf.org/html/draft-ietf-core-coap-18, section 4.4)
"It is strongly recommended that the initial value of the
variable (e.g., on startup) be randomized, in order to make successful
off-path attacks on the protocol less likely."
Doing this in a dedicated init function is the cleanest and most
idiomatic approach. This init function is not exposed publically which
means it will be called only once, by the network stack init procedure.

When small blocks are recombined to create a single block at a shallower
level, it is sufficient to remove those blocks from the free list. There
is no need to mark those small blocks as allocated in the bitmap.
This, in turn, removes the need to mark small blocks back as unallocated
when splitting up a big blocks as they'll already be so marked.
Only the first small block needs to be marked allocated and the
remaining blocks only need to be added to the free list.
This makes the code smaller and more efficient, especially since those
removed bit manipulations were located within loops.

This turns the free-bit flag into an alloc-bit flag effectively
reversing its semantic. This is to make further changes more natural
and easier to understand.
No need to clear the alloc bits at init time as they're located in .bss

This option determines the name under which the device represented by
the `sw_pwm` node is registered in the system. But when the value of
this option does not match the `label` property of the `sw_pwm` node,
a problem arises when the `sw_pwm` node is referenced by a "pwm-leds"
compatible node, since the `*_PWMS_CONTROLLER` macro that is generated
for this referencing node contains a non-existing device name (as it is
the `label` property value, not the Kconfig option value).
This commit solves the issue described above by removing the Kconfig
option and replacing all of its occurrences in sample applications
by the standard macro generated for the `sw_pwm` node, containing
the value of the `label` property of this node.
