Modifications to portENTER_CRITICAL.
* Modifications to portENTER_CRITICAL.
*
* For an introduction, see "Critical Sections & Disabling Interrupts" in docs/api-guides/freertos-smp.rst
*
* The original portENTER_CRITICAL only disabled the ISRs. This is enough for single-CPU operation: by
* disabling the interrupts, there is no task switch so no other tasks can meddle in the data, and because
* interrupts are disabled, ISRs can't corrupt data structures either.
*
* For multiprocessing, things get a bit more hairy. First of all, disabling the interrupts doesn't stop
* the tasks or ISRs on the other processors meddling with our CPU. For tasks, this is solved by adding
* a spinlock to the portENTER_CRITICAL macro. A task running on the other CPU accessing the same data will
* spinlock in the portENTER_CRITICAL code until the first CPU is done.
*
* For ISRs, we now also need muxes: while portENTER_CRITICAL disabling interrupts will stop ISRs on the same
* CPU from meddling with the data, it does not stop interrupts on the other cores from interfering with the
* data. For this, we also use a spinlock in the routines called by the ISR, but these spinlocks
* do not disable the interrupts (because they already are).
*
* This all assumes that interrupts are either entirely disabled or enabled. Interrupt priority levels
* will break this scheme.
*
* Remark: For the ESP32, portENTER_CRITICAL and portENTER_CRITICAL_ISR both alias vTaskEnterCritical, meaning
* that either function can be called both from ISR as well as task context. This is not standard FreeRTOS
* behaviour; please keep this in mind if you need any compatibility with other FreeRTOS implementations.
