to armv7-a/arm_physpgaddr.c (2014-9-16).
* arch/arm/src/sam34/sam_rtt.c: Only SAM4 family has RTTDIS bit in the
MR register. SourceForge bug #33 from Fabien Comte (2014-9-17).
* arch/arm/src/stm32/stm32_can.c: At the end of the interrupt handler,
the interrupts were being disabled, if all packets have been
transferred when the interrupt handler was invoked. This is
problematic, because the interrupt handler calls can_txdone of the
upper half which can enqueue new packets to send. Removed the block
altogether, because can_txdone calls can_xmit which disables
interrupts if there are no new packets to send. From Daniel Lazlo
Sitzer (2103-9-17).
* drivers/can.c: In can_txdone, waiters on the semaphore should be
informed regardless of the return value of can_xmit. First it returns
-EIO if there are no new packets, and second the information of the
waiters is about the last transferred packet. From Daniel Lazlo
Sitzer (2103-9-17).
