72e248b11b adv_power:Rename PM functions according to coding convention
Renamed functions and labels used in power management code
according to coding convention.  Only doing this to relevant
functions and not touching functions that will be removed in
future patches.

The stack used during resume would be necessary so
renamed that too.

038790a945 sys_clock/microkernel: do not announce ticks until microkernel is up
This is a prologue to reverting:

	commit 3c66686
	Author: Benjamin Walsh <benjamin.walsh@windriver.com>
	Date:   Tue Feb 9 17:34:02 2016 -0500

		sys_clock: start the microkernel ticker in the MICROKERNEL init level

to allow the devices initializing in pre-MICROKERNEL init levels to poll
the hi-res clock (sys_cycle_get_32()), which relies on the system clock
having been started.

This change allows starting the system clock in the NANOKERNEL init
level by delaying announcing the ticks until the MICROKERNEL init level.

65ec185f79 logger: include task monitor in kernel event logger
Zephyr includes a Task Monitor feature that allows to
track events on the microkernel server scheduler.
Task monitor is integrated as a profiler point for the
Kernel Event Logger feature.

583126adf9 microkernel: remove task_irq_free() API
This is being removed for a few reasons:

- AFAICT this is the only API in Zephyr that follows an allocate/free
model.

- There are no public APIs in the interrupt subsystem for releasing
or reconfiguring an interrupt. This code was relying on arch-specific
private APIs. If we really want to keep this capability we should
make these APIs public and consistent across arches.

- The use-case for this API is not clear, as Zephyr is not intended
for hot-pluggable peripherals. Built-in hardware tends to need its
interrupt for its entire life cycle.

- The current implementation of dynamic interrupts on x86 does not
support freeing a dynamic IRQ that was reserved with
irq_connect_dynamic(), causing this code not to work. To add this
would require reimplementing _get_dynamic_stub() to use a bitfield
or set of bitfields to track unused stubs rather than the simple
counter it uses now.

d9cfbd5a61 interrupts: new static IRQ API
The interrupt API has been redesigned:

- irq_connect() for dynamic interrupts renamed to irq_connect_dynamic().
  It will be used in situations where the new static irq_connect()
  won't work, i.e. the value of arguments can't be computed at build time
- a new API for static interrupts replaces irq_connect(). it is used
  exactly the same way as its dynamic counterpart. The old static irq
  macros will be removed
- Separate stub assembly files are no longer needed as the stubs are now
  generated inline with irq_connect()

ReST documentation updated for the changed API. Some detail about the
IDT in ROM added, and an oblique reference to the internal-only
_irq_handler_set() API removed; we don't talk about internal APIs in
the official documentation.

5c01c09f4d nano_stack: Simplify nano_xxx_stack_pop() API family
Changes the nanokernel stack API so that the timeout parameter must be
specified when invoking nano_isr_stack_pop(), nano_fiber_stack_pop(),
nano_task_stack_pop() and nano_stack_pop().

This obsoletes the following APIs:
	nano_fiber_stack_pop_wait()
	nano_task_stack_pop_wait()
	nano_stack_pop_wait()

Note that even though the new API requires that the timeout parameter
be specified, there are currently only two acceptable values:
	TICKS_NONE and TICKS_UNLIMITED
This nanokernel option does not support CONFIG_NANO_TIMEOUTS.

0c8965fd99 kernel: Specify alignment of microkernel server command stack items
The microkernel server now relies on the fact that the command packets,
events, and semaphores passed to it via its command stack are 32 bit
aligned. This change explicitly ensures this alignment, rather than
leaving it to the compiler's discretion.

7c4b9ce1f7 kernel: Eliminate the need for command packet sets
Revises microkernel semaphore sub-system to allow ISRs and fibers
to give a semaphore without having to define a command packet set.
The microkernel server now supports a 3rd command type on its
command stack, allowing a semaphore to be given in a similar manner
to the one used for the existing "give event" command type.

16504c27c1 kernel: Revise microkernel server's recognition of command types
Revises microkernel server command stack processing to allow the
server to support more than 2 types of commands. The lowest 2 bits
of the command now indicate the command's type:

0 - process specified command packet
1 - give specified event (from ISR or fiber)
2 - give specified semaphore (from ISR or fiber)
3 - reserved for future use

Note: Support for type 2 will be provided in a future commit.

The test has been modified a little bit due to the fact that

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.

ddaebc15b3 kernel: Eliminate use of main() in microkernel
Revises microkernel initialization code by incorporating the existing
_k_kernel_init() and main() routines into _main(). This optimizes kernel
initialization a bit, and allows application code to use main()
if desired -- for example, as the entry point to an application task.
The change also eliminates the need for sysgen to generate a routine
whose content is always the same.

This change preserves the existing order of operations done during
kernel initialization, and leaves further improvements for later.

8253b90cfc microkernel: add task pointer list
Due to similar padding issue as pipe, the list of task object
may not be used directly. As mentioned before, some compiler/linker
may pad the large struct. For example, compiling under gcc and
march=i686 pads the struct to 32-byte alignment (march=atom to
64-byte alignment). This causes issue with sizeof() and pointer
arithmetic because they have no idea about the padding.
When the stars align in a certain way, these task structs may be
corrupted. So add a task pointer list and use it for task
manipulation. The task list remains as it is beneficial to group
them together to take advantage of cache locality.
