8048b14135 ARC: allow to build code for processors without ZOL
ARCv3 64 bit processors doesn't have Zero Delay Loop
(also named Zero Overhead Loop, ZOL) mechanism. Add kconfig
option to remove ZOL register save/restore so the code
can be build for both ARCv2 and ARCv3.

3f12ca57b8 ARC: make vector table bit agnostic
ARCv2 32 bit and ARCv3 64 bit share the same vector table
structure but with different vector entry size (32 and 64 bit),
so we can easily make vector table bit agnostic.

3632815e2e api: gpio: do not support INT flags in gpio_pin_configure
To keep compatibility between the old GPIO API implementation and a new
one introduced in the Zephyr 2.2.0 release the gpio_pin_configure()
function was accepting interrupt flags. In the new API implementation
interrupt flags are only accepted by gpio_pin_interrupt_configure()
function.

This temporary support for INT flags in gpio_pin_configure should have
been removed in the Zephyr 2.4.0 release.

a0bea0812a drivers: intc: intrc_shared: get client count from SUPPORTS_DEP_ORDS
The intc_shared driver used kconfig to set the number of clients.
This commit changes the driver to determine the number of clients
per instance using supports ordinals information from device tree.

Leave the kconfig symbol for the number of clients, it now only defines
the array size in driver data and therefore an upper limit of how
many clients can be defined in dts.
It will be removed later with changes of driver data struct.

085d3768e1 kernel: mmu: introduce arch_page_phys_get()
This adds a new function prototype for arch_page_phys_get()
which will be used to translate mapped virtual addresses back
to physical memory addresses. This is needed for the future
k_mem_unmap() function which requires this to find
the corresponding page frame. It is faster to look through
the page tables instead of doing linear search of the page
frame array.

A weak function is provided in case arch_page_phys_get()
is not implemented at the arch level. This simply goes
through all the page frame and find the one which has
mapped to the virtual address.

specified or not. So just unconditionally enable guard pages on
