cc1208fb5f Bluetooth: Fix invalid value length type
BTP protocol specifies value length to be 2 octets value,
so uint16_t has to be used to store this length.

7ee4fa4473 Bluetooth: SMP: Fix crash when using KeyboardOnly capabilities
This fix crash due to calling auth callback from wrong pointer.
get_io_capa was using bt_smp_io_capa instead of structure provided
in argument. This resulted in checking NULL pointer for provided
callbacks. By coincident this always returned
BT_SMP_IO_KEYBOARD_DISPLAY (first 8 bytes in memory were non-zero)
and resulted in calling callback from NULL address if application
didn't provided passkey_display or passkey_entry callbacks.

a51d61d214 Bluetooth: SMP: Fix not allowing any PDU after pairing is finished
If pairing was finished it is perfectly fine for remote to send
another SMP PDU and start new pairing.

To make code simpler just use smp_reset() to set SMP into correct

Gets rid of the trailing initialization level character from the

sections in ascending order based on the name of the section, so there
is no need to embed the initialization level in the variable name itself.)

f330d5adfe microkernel: Don't initialize packets in a command packet set
Reworks the internal design of a command packet set so that
the command packet array is split out into a separate variable
lying in uninitialized memory. This shrinks the command packet's
data section footprint to almost nothing.

Note: A side effect of this change is that it is no longer possible
to define a command packet set as a "static" variable since the
CMD_PKT_SET_INSTANCE() macro now generates two variables.

GPIO driver is initialized at pre-kernel-late level, if SPI does it too,
it will happen before GPIO (depends on the ordered list of
initialization). In order to ensure it gets GPIO initialized always
before SPI, let's set SPI to initalize at the next level: nano-early.

c1c1ffe7f7 doc: Change API tables to lists in the Kernel Primer.
The tables in the Kernel Primer are changed to lists. Making it easier
to update them. Other minor changes were done to ensure consitency.
The :c: and :cpp: markup has been fixed. When the documentation for a
call exists, then it is linked.

5705d06874 x86: Properly initialize _interrupt_vectors_allocated[] bitmap
Updates the 'gen_idt' tool to generate a bitmap of (statically) allocated
interrupt vectors that is linked into the final image in a manner similar to
the static IDT. The kernel then uses this bitmap when dynamically connecting
an interrupt vector, thereby preventing the dynamic irq connections
from clobbering the static irq connections.

56fa1a98d0 x86: Update generation of static IDT
Adds two new fields to the ISR_LIST structure (irq and priority) to allow
the decoupling of the vector ID and priority from the IRQ number at some
future time.

As a result of the addition of these two new fields, the gen_idt tool is
modified to both process these new fields as well as validate them.

25359412ba x86: Do not use IRQ priority for DPL
Fixes a bug in the x86 IRQ_CONNECT_STATIC() macro that resulted in setting
the DPL for the interrupt to the IRQ priority level.

Note 1: Using a proper value for the DPL (instead of the priority) prevents
the corruption of the other IDT fields.

Note 2: The priority of the IRQ is completely ignored.

3bcaad8a39 x86: Simplify _IntVecAlloc() logic
Instead of using logic choosing between invoking find_lsb_set() and
find_msb_set(), mask out the unwanted bits and always invoke find_lsb_set().
This also has the side benefit of simplifying the error checking when DEBUG is
enabled.

616ca21599 x86: Lock interrupts when connecting interrupts
When dyanmicaly connecting an interrupt via irq_connect(), interrupts must be
locked both when allocating a dynamic interrupt stub and when updating the
interrupt descriptor table (IDT) to prevent race conditions.
