Add information how to run two QEMUs and have IEEE 802.15.4 link
layer over UART between them. This is useful if one needs to test
basic IEEE 802.15.4 functionality without a IEEE 802.15.4 radio.

re-enabling this test was premature, it still crashes very often
due to two known issues affecting x86 64-bit. Filter out for
every 64-bit x86 platform until those bugs are solved, which
will reduce CI failure noise.

This build target has all the low-memory options enabled for
memory management: a 4MB address space, 32-bit paging mode,
no KPTI, an empty page pool, and common page tables for
memory domains.
Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
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.

This will do until we can set up a proper page pool using
all unused ram for paging structures, heaps, and anonymous
mappings.

These are set such that we have enough pages in the pool

We don't need this for stacks any more and only use this

We need to make sure that if we migrate a thread to another
memory domain, the migration process doesn't cause the target
thread to explode. This is mostly a concern on SMP systems;
the thread could be running on another CPU at the same time.

- 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.

Page table management for x86 is being revised such that there
will not in many cases be a pristine, master set of page tables.
Instead, when mapping memory, use unused PTE bits to store the
original RW, US, and XD settings when the mapping was made.
This will allow memory domains to alter page tables while still
being able to restore the original mapping permissions.

This will be needed when we support memory un-mapping, or
the same user mode page tables on multiple CPUs. Neither
are implemented yet.

Call mbedtls_ssl_conf_max_frag_len() on created TLS context
configuration, so that Maximum Fragment Length (MFL) will be sent to
peer using RFC 6066 max_fragment_length extension. MFL value is
automatically chosen based on MBEDTLS_SSL_OUT_CONTENT_LEN and
MBEDTLS_SSL_IN_CONTENT_LEN mbed TLS macros.
This extension is mostly useful for TLS client side to tell TLS server
what is the maximum supported receive record length.

ull_adv_data_set() is only used for legacy advertising data (either via

We handle secondary channel only for extended advertising sets, that
means we always have ADV_EXT_IND on primary channel so there is no need

Adds CLAMP macro to complement the current min/max macros, as well as a

codebase in every possible combination.

k_object_alloc(K_OBJ_THREAD) returns a usable struct k_thread pointer.
This pointer is 4 byte aligned. On x86 and x86_64 struct _thread_arch
has a member which requires alignment. Since this is currently not
supported k_object_alloc(K_OBJ_THREAD) now returns an error instead of
a misaligned pointer.
