Andrew Boie bba9510319 irq_offload: API to run a function in IRQ context
Software interrupts or system calls aren't really appropriate for
zephyr, but we have an ongoing need in our test code to run a
function with arguments synchronously in interrupt context.

This patch introduces irq_offload() which allows us to do this without
separate initialization or having to manage fake IRQs in the
interrupt controller.

ARM assembly code contributed by Benjamin Walsh
<benjamin.walsh@windriver.com>

ARC is not yet implemented but will be in a subsequent patch.

irq_test_common.h has been removed and all test cases updated to
use the new API.

Anas Nashif 77ba3c3b8b kconfig: define architecture as a kconfig variable
Do not depend on environment variables and use a kconfig variable
for defining the architecture.

In addition, remove the X86_32 variable, it just duplicates X86 for
not good reason, at least until start supporting MCUs with 64bit.

Dmitriy Korovkin f1420515a7 irq: Add flags to IRQ_CONNECT_STATIC() macro and irq_connect() function
Flags allow passing IRQ triggering option for x86 architecture.
Each platform defines flags for a particular device and then
device driver uses them when registers the interrupt handler.

The change in API means that device drivers and sample
applications need to use the new API.

IRQ triggering configuration is now handled by device drivers
by using flags passed to interrupt registering API:
IRQ_CONNECT_STATIC() or irq_connect()

Andrew Boie b43758d22a x86: remove dynamically generated IRQ and exception code
We are interested in supporting some XIP x86 platforms which are
unable to fetch CPU instructions from system RAM. This requires
refactoring our dynamic IRQ/exc code which currently synthesizes
assembly language instructions to create IRQ stubs on-the-fly.

Instead, a new approach is taken. Given that the configuration at
build time specifies the number of required stubs, use this
to generate a build time a set of tiny stub functions which simply
push a 'stub id' and then call common dynamic interrupt code.
The handler function and handler argument is saved in a table keyed by
this stub id.

CONFIG_EOI_HANDLER_SUPPORTED removed, the code hasn't been conditionally
compiled for some time and in all cases we call _loapic_eoi() when
finished with an interrupt.

Some other out-of-date verbiage in comments related to supporting
non-APIC removed.

Previously, when dynamic exceptions were created a pointer would
be passed in by the caller reserving ram for the stub code. Since
this is no longer feasible, two new Kconfig options have been added.
CONFIG_NUM_DYNAMIC_EXC_STUBS and CONFIG_NUM_DYNAMIC_EXC_NO_ERR_STUBS
control how many stubs are created for exceptions that push
an error code, and no error code, respectively.

SW Interrupts are no longer triggered by "int <vector>" hard-coded
assembly instructions. Instead this is done by sending a self-directed
inter-processor interrupt from the LOAPIC, using a new API
loapic_int_vect_trigger(). In this way we get rid of dynamically
generated code in irq_test_common.h.

All interrupts call _loapic_eoi() when finished, since this is now
the right thing to do for all IRQs, including SW interrupts.

_irq_handler_set() for x86 no longer requires the old function pointer
to be supplied.

Dmitriy Korovkin 660878e4e2 irq_connect for x86 uses static stub array
In order to provide the same irq_connect() on all platforms
on x86, irq_connect() now uses a static array of interrupt
stubs. Device driver does not need to provide interrupt stub
to irq_connect() function.

Add NUM_DYNAMIC_STUBS configuration parameter, the number
of interrupt stubs used for dynamic interrupt registration.

Modify tests for unified interrupt register API

Tests that deal with interrupts are modified to work
with the new interrupt registration API.

Add CONFIG_NUM_DYNAMIC_STUBS option to dynamic interrupt projects

Projects that use dynamic interrupt handler registration on x86
have to include CONFIG_NUM_DYNAMIC_STUBS parameter in the
configuration.

Yonattan Louise dbada63eee Fix coding style issues.
Some checkpatch issues were solved by scripts leaving other problems
such as alignment and indentation issues.  In order to comply with the
defined coding style the following fixes were made:

- Fixed the function declaration moving the parameters' comments above
  the function in accordance to the doxygen format.
- Fixed functions' opening and closing brackets. These brackets should
  not be indented.
- Fixed the 'if', 'for' and 'while' statements adding the brackets
  around the sentence.
- Fixed comments' alignment.
- Fixed indentation.

The work was done manually and submitted as one commit. I didn't
separate these changes in different commits because they were fixed all
at once. Basically, all errors were fixed in every file at once.
