+ IRQ handling faster and also saves some RAM/ROM space. The GCC port code
+ now does not inline the epilogue code in each ISR saving significan ROM
+ space for each interrupt handler in the system (backported to 2.2.3).
- NEW: Added "IRQ STORM" long duration tests for the STM32 and LPC11xx. The
test demonstrates the system stability in a thread-intensive, progressively
CPU-saturating, IRQ-intensive long duration test.
