Currently the Coverity Scan attempts to run on every fork that pulls
the file. This leads to anybody who pulls this file getting emails that
their workflow failed to run when the cron job attempts to run. This
PR sets the scan to only run if the repo is FreeRTOS/FreeRTOS-Kernel.
Also, change the scan from a cron job to a job that runs on a commit
to mainline, or if triggered manually.
Earlier the System Call entry from an unprivileged task
looked like:
1. SVC for entering system call.
2. System call implementation.
3. SVC for exiting system call.
Now, the system call entry needs to make only one SVC
call and everything else is handled internally.
This PR also makes the following changes:
1. Update the Access Control List (ACL) mechanism to
grant access to all the kernel objects before the
scheduler is started.
2. Add one struct param for system calls with 5 parameters.
This removes the need for special handling for system
calls with 5 parameters.
3. Remove raise privilege SVC when MPU wrapper v2 is used.
4. Add additional run time parameter checks to MPU wrappers
for xTaskGenericNotify and xQueueTakeMutexRecursive APIs.
* Update vApplicationGetIdleTaskMemory prototype for SMP. Now SMP and
single core use the same prototype for compatibility.
* Add vApplicationGetPassiveIdleTaskMemory for SMP to get passive idle
task memory.
This commit updates the following time conversion macros:
- pdMS_TO_TICKS: Added cast to "uint64_t" to prevent overflow
- pdTICKS_TO_MS: Added macro to convert ticks to milliseconds

The function vTaskSwitchContext in smp has an parameter of core id,
which means this function is not only used for the core who call it.
Thus we should use the task running on the specific core id,
instead of use the task running on the core who call this function.

The Cortex-A53 ports are generic and can be used as a starting point
for other Armv8-A application processors. Therefore, rename
`ARM_CA53_64_BIT` to `Arm_AARCH64` and `ARM_CA53_64_BIT_SRE` to
`Arm_AARCH64_SRE`.
With this renaming, existing projects that use old port, should
migrate to renamed port as follows:
* `ARM_CA53_64_BIT` -> `Arm_AARCH64`
* `ARM_CA53_64_BIT_SRE` -> `Arm_AARCH64_SRE`

This commit renames "CPU" to "Core" for any public facing API for consistency
with other SMP related APIs (e.g., "configNUMBER_OF_CORES").

To build a complete static application (configSUPPORT_DYNAMIC_ALLOCATION
set to 0) an ugly workaround is necessary, because when FREERTOS_HEAP is
not set, heap 4 is automatically selected in the current CMake.

This PR fixes the bug described in the following issue:
https://github.com/FreeRTOS/FreeRTOS-Kernel/issues/612.
This was originally contributed in the following PR:
https://github.com/FreeRTOS/FreeRTOS-Kernel/pull/625.
The implementation suspends the scheduler before exiting the
critical section (i.e. before enabling interrupts). If we do not do
so, a notification sent from an ISR, which happens after exiting
the critical section and before suspending the scheduler, will
get lost. The sequence of events will be:
1. Exit critical section.
2. Interrupt - ISR calls xTaskNotifyFromISR which adds the task to
the Ready list.
3. Suspend scheduler.
4. prvAddCurrentTaskToDelayedList moves the task to the delayed
or suspended list.
5. Resume scheduler does not touch the task (because it is not on
the pendingReady list), effectively losing the notification from
the ISR.
The same does not happen when we suspend the scheduler before
exiting the critical section. The sequence of events in this case will
be:
1. Suspend scheduler.
2. Exit critical section.
3. Interrupt - ISR calls xTaskNotifyFromISR which adds the task to
the pendingReady list as the scheduler is suspended.
4. prvAddCurrentTaskToDelayedList adds the task to delayed or
suspended list. Note that this operation does not nullify the add
to pendingReady list done in the above step because a different
list item, namely xEventListItem, is used for adding the task to the
pendingReady list. In other words, the task still remains on the
pendingReady list.
5. Resume scheduler moves the task from pendingReady list to the Ready list.

This PR introduces the configTIMER_SERVICE_TASK_CORE_AFFINITY option
which allows the system to configure the core affinity of the Timer
Service Task on an SMP system. The default affinity of the Timer Service
Task is set to tskNO_AFFINITY which is the current behavior on SMP
systems.
