are still supported when the feature is disabled but the scheduling among
them becomes cooperative.
+- OPT: Improved reschedulation time by reordering the sequence of operations,
+ now during enqueuing the ready list contains one less element. This change
+ also slightly improves the interrupt latency.
+- OPT: Optimization to the chSemReset(), reversed the order of dequeuing.
- FIX: Fixed a bug in the chThdSetPriority() API.
- FIX: Modified the structure names into nvic.h in order to not make them
collide with external libraries.
+- Added a benchmark to the test suit that measures the mass reschedulation
+ performance.
- Made the Cortex-M3 port preemption code more readable.
