Andrew Boie d0ab1a816e arc: arm: don't use recursion to create _sw_isr_table
Causes problems for large values of CONFIG_NUM_IRQS.
Some inconsistencies have been noted in how CONFIG_NUM_IRQS is
used on these platforms, with bugs filed. This patch preserves
existing behavior and has been shown to generate the same number
of table entries for both arches using objdump.

Anas Nashif 10bb38c186 Use SoC instead of platform.
Change terminology and use SoC instead of platform. An SoC provides
features and default configurations available with an SoC. A board
implements the SoC and adds more features and IP block specific to the
board to extend the SoC functionality such as sensors and debugging
features.

Benjamin Walsh 3181df6db4 kernel: add per-thread errno support
Saves an errno per-thread, retrieved via _get_errno(), instead of
changing the value of a global variable during context switches to avoid
a hit to the context switch performance.

Per-arch asm implementations are provided for maximum performance.

Enabled by default, but can be disabled via the CONFIG_ERRNO option.

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.

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()

Benjamin Walsh 0dcad8331b clarify use of term 'context'
The term 'context' is vague and overloaded. Its usage for 'an execution
context' is now referred as such, in both comments and some APIs' names.
When the execution context can only be a fiber or a task (i.e. not an
ISR), it is referred to as a 'thread', again in comments and everywhere
in the code.

APIs that had their names changed:

  - nano_context_id_t is now nano_thread_id_t
  - context_self_get() is now sys_thread_self_get()
  - context_type_get() is now sys_execution_context_type_get()
  - context_custom_data_set/get() are now
    sys_thread_custom_data_set/get()

The 'context' prefix namespace does not have to be reserved by the
kernel anymore.

The Context Control Structure (CCS) data structure is now the Thread
Control Structure (TCS):

  - struct ccs is now struct tcs
  - tCCS is now tTCS

Daniel Leung 74c8852d05 microkernel: remove kernel service dispatch table
This change removes the internal number-to-function mapping
of microkernel services. Instead, function pointers are used
to specify which service to use.

This is in preparation for private kernel objects. Before this,
only kernel objects that are defined in MDEF files would have
corresponding functions included in the final binary, via sysgen
by populating an array of number-to-function mapping. This
causes an issue when a certain type of objects are all defined
with source code, and never in MDEF file. The corresponding
mapping would be deleted, and the functions are never included
in the binary. For example, if no mutexes are defined in MDEF
file, the _k_mutex_*() functions would not be included.

With this change, any usage of private kernel objects will hint
to the linker that those functions are needed, and should not be
removed from final binary.

Instead of initializing the stack (when INIT_STACKS is enabled) in start_task()
and _fiber_start(), do it in _NewContext().  This helps to both reduce code
duplication AND ensure that all contexts get an initialized stack (previously
the background/idle task's was missed).

According to section 3.7 of Documentation/kbuild/makefiles.txt, using
EXTRA_CFLAGS in Makefiles is "still supported but their usage is
deprecated." However, using make EXTRA_CFLAGS="-DSOMETHING" results in
EXTRA_CFLAGS from Makefiles being overwritten, obviously breaking the
build.  This patch converts to them to the newer ccflags-y which also
fixes the problem.

Peter Mitsis 40b5200c73 Optimizations to _NewContext() and _NewContextInternal()
Since the address of the new context is known before _NewContext() is invoked
(due to it being passed a properly aligned stack), there is no longer any
need for _NewContext to return the pointer to the context.

Furthermore, as a direct result of the properly aligned stack, the pointer to
the new context does not need to be passed as a separate parameter since it
will always match the passed stack pointer.

This commit fixes issues to allow build on ARM architecture.
- It fixes the include paths in Makefiles.
- It fixes the include path for the offsets.c compilation.
- It fixes the linker command. This changes is needed because gcc
  ARM cross-compiler does not accept an AT() command without
  specifing an address explicitly. This corner case appears
  on ARM architectures when XIP is disabled.

Allan Stephens a02396098d Eliminate exposure of non-public microkernel structures
Renames the include file defining non-public microkernel structures
from k_struct.h to kernel_structures.h, and relocates it to the
microkernel's non-public include file directory. This means that
applications and drivers including the microkernel's public APIs,
using microkernel.h, can no longer access non-public information.

Note: This change also eliminates some redundant #includes by the
microkernel's own subsystems, since the inclusion of minik.h brings
in the vast majority of public and non-public APIs.

Peter Mitsis 101d486834 Rename k_args 'Srce' field to 'alloc'
Since multi-node systems are not supported, the 'Srce' field now only serves
one purpose--to indicate whether the packet was allocated from the command
packet pool.  As such, a better name (and type) for it is 'alloc' (of type
'bool') since 'Srce' (of type 'knode_t') suggest multi-node support.
