The kernel code that runs within RTOS ISRs requires that DP and CP not
be changed from their initial values. If a task changes them and is
interrupted while they are changed, then they must be restored for the
ISR. This commit implements this.
This relies on a corresponding change to the xcore lib_rtos_support.
* Add XMOS XCore ports
Some minor modifications are also made to the kernel to support the
XCore compiler's automatic stack size calculation.
* Update kernel to support SMP
The XMOS XCore ports are also updated to support SMP.
* Fix compiler warnings in xcore ports
The port set and clear interrupt mask from ISR macros were removed from
the ports so that the default macros found in FreeRTOS.h are used
instead. The default macros do not result in warnings when they are
used.
* Remove inline function from timers.h
Inline function converted to macro. This should now build when
optimizations are off and inlining is disabled.
* Fix compiler warnings in xcore ports and tasks.c
* fixed documentation for ulTaskNotifyTake() and ulTaskNotifyTakeIndexed()
* spelling fixes for tasks.c
* adding the kernel SMP documentation

The tick interrupt priority must be configured to ensure that it cannot
interrupt a critical section. This change updates the comment to help
the application writer while debugging.

* Add an LCOV_BRANCH exception for the check that sizeof( StaticQueue_t ) == sizeof( Queue_t )
* Add LCOV_BRANCH coverage exception for a configASSERT on pxQueueSetContainer with a condition that is unreachable.
* Add configASSERTs to alert when invalid parameters are passed into Queue Registry related functions.
* Assert that the semaphore handle passed into xQueueGetMutexHolder is not NULL.
* Correct some typos in queue.c
* Update lexicon.txt
The change adds support for allocating task stacks from separate heap.
When configSTACK_ALLOCATION_FROM_SEPARATE_HEAP is defined as 1 in
FreeRTOSConfig.h, task stacks are allocated and freed using
pvPortMallocStack and vPortFreeStack functions. This allows the
application writer to provide a separate allocator for task stacks.
When configSTACK_ALLOCATION_FROM_SEPARATE_HEAP is defined as 0, task
stacks are allocated and freed using FreeRTOS heap functions
pvPortMalloc and vPortFree.
For backward compatibility, configSTACK_ALLOCATION_FROM_SEPARATE_HEAP
defaults to 0.
