Convention is to call k_mem_page_fault() with IRQs enabled if they were
enabled when the fault occurred.

This has two purposes: maintain the accessed and dirty page states, or
call the generic demand paging fault handler otherwise.

A page table entry used for demand paging is always from the last level
page table and never completely zeroed. Anything else is considered
ARCH_DATA_PAGE_NOT_MAPPED.
Loaded pages use a PTE_PAGE_DESC table entry type. Paged-out pages use a
PTE_INVALID_DESC table entry type and the physical address field is
reused to hold the backing store location token value.
ARCH_DATA_PAGE_ACCESSED corresponds to the AF flag. It is initially
unset and manually set to catch when pages are being accessed and
eventually do something about it.
ARCH_DATA_PAGE_DIRTY corresponds to the lack of the AP_RO flag.
Similarly to the AF flag, pages are initially made read-only to catch
writes.

Let's consider free entries as being completely zeroed. Future patches
for demand paging support will populate entries and still mark them as
"invalid" which should not be considered free. Current code always clear
entries to be freed so no issues there.

Add information to the device tree if UARTE instance has a HW feature
which is the ENDTX_STOPTX short.
Add this property to all instances in nrf54hl15, nrf54l20, nrf9280
and nrf54h20.

There is a regression caused by #76177, which
causes build to fail due to missing includes and others.
This wraps it with proper checks and fixes wifi scan call.
This also remove unused variable present in the same driver.

The unit tests needed to enable the hidden Kconfig
BT_BAP_BASE. Instead of adding an additional Kconfig for this,
just enable one of the roles that enable it.

There were a couple of controller tests outside the

When running cmake directly (without west, as twister does) on nix the
CMake environment paths are set and thus it does not find the
virtualenv'ed python. Fix this by ignoring the cmake environment
variables nix sets.
