+/* This header exists for performance reasons, in order to inline the
+   implementation of vPortCPUAcquireMutexIntsDisabled and
+   vPortCPUReleaseMutexIntsDisabled into the
+   vTaskEnterCritical/vTaskExitCritical functions in task.c as well as the
+   vPortCPUAcquireMutex/vPortCPUReleaseMutex implementations.
+
+   Normally this kind of performance hack is over the top, but
+   vTaskEnterCritical/vTaskExitCritical is called a great
+   deal by FreeRTOS internals.
+
+   It should be #included by freertos port.c or tasks.c, in esp-idf.
+
+   The way it works is that it essentially uses portmux_impl.inc.h as a
+   generator template of sorts. When no external memory is used, this 
+   template is only used to generate the vPortCPUAcquireMutexIntsDisabledInternal
+   and vPortCPUReleaseMutexIntsDisabledInternal functions, which use S32C1 to
+   do an atomic compare & swap. When external memory is used the functions
+   vPortCPUAcquireMutexIntsDisabledExtram and vPortCPUReleaseMutexIntsDisabledExtram
+   are also generated, which use uxPortCompareSetExtram to fake the S32C1 instruction.
+   The wrapper functions vPortCPUAcquireMutexIntsDisabled and 
+   vPortCPUReleaseMutexIntsDisabled will then use the appropriate function to do the
+   actual lock/unlock.
