The test assumes that the last to IRQ number will be free, this isn't a
valid assumption and now that we detect multiple ISRs registering for
the some IRQ line, we see failures because of this assumption on some
platforms. Exclude those platforms from this test for the time being.

The error message is obscure when CONFIG_PRIVILEGED_STACK_TEXT_AREA is
configured incorrectly. It looks like this:
zephyr/linker.cmd:73 cannot move location counter backwards (from
0000000000069bfc to 0000000000069bd8)
This patch re-writes the linker script mechanism in a (believed and
tested) semantically equivalent way such that it is possible to use an
assertion.
The assertion's error message now looks like this:
Memory region Used Size Region Size %age Used
FLASH: 503012 B 1 MB 47.97%
SRAM: 53760 B 256 KB 20.51%
IDT_LIST: 120 B 2 KB 5.86
real-ld: The configuration system has incorrectly set
'CONFIG_PRIVILEGED_STACK_TEXT_AREA' to
128, which is not big enough. You must
through Kconfig either disable 'CONFIG_USERSPACE', or set
'CONFIG_PRIVILEGED_STACK_TEXT_AREA' to a value larger than
128 .

For networking code, it does not make sense to have zero net_buf
or net_pkt instances. Make sure this is enforced by code.

pkt->buffer is represented by 1+ net_buf. If some are unused, this will
deallocates them.
This situation can happen on TCP where net_pkt allocator evaluates the
header size to its maximum size. Which space might not be (fully) used
in the end. On fixed data size buffer, this might end up by having last
buffer(s) not bein used. So better removing those.

DNS callback needs "struct shell *shell" data structure to pass as
a parameter to shell print. How it was achieved previously is that
it was packaged together with cosmetic "bool first" param into
"struct net_shell_user_data" on the stack, and passed to the
callback. The problem was that the original command handler then
returned, so the "struct net_shell_user_data" on the stack was
overwritten, and the callback crashed on accessing it.
An obvious solution was to make that structure static, but that would
leave to issues still, as turns out we allow system shell to be run
as more than one concurrent instances.
Next solution was to keep this structure on the stack, but block the
command handler until callback is finished. However, that hit a
deadlock due to not well thought out use of a mutex in the shell
printing routines.
The solution presented here is due to @nordic-krch, who noticed that
"bool first" param is indeed cosmetic and not really required. Then
we have only "struct shell *shell" to pass to the callback, and can
do that in callback's pointer param directly, ditching
"struct net_shell_user_data" which needs to be stored on the stack.

_arch_configure_dynamic_mpu_regions() may re-program the MPU
Stack Guard, to guard the privilege stack for overflows,
(if building with option CONFIG_MPU_STACK_GUARD). There is a
risk of actually overflowing the stack while doing the
re-programming. We minimize the risk by placing the
re-programming function immediately after we have switched to
the privileged stack so that the whole privilege stack area is
available for this critical operation.
Note that the risk for overflow is higher if using the normal
thread stack, since we do not control how much stack is actually
left, when user invokes _arm_userspace_enter().

This commit moves the clearing of PSPLIM before determining the

This commit provides two fixes for the ARMv8-M built-in stack
protection in userspace.S. First, it clears the PSPLIM register
before setting the PSP to the privileged stack. In the wake of
this, the privilege stack area can now be positioned enywhere,
i.e. does not have to be above the user stack area. Second, it
removes unncessary push/pop when clearing the PSPLIM register,
upon returning from the system call, since the r3 register is
not used anymore in this routine.
