* arch/arm/src/stm32/stm32f2xx_dma.c and stm32f4xx_dma.c: Backed out the
DMA priority change just above. The reduced SD card frequency was
necessary and sufficient to resolve the problem.
* drivers/serial/serial.c: open, read, write, and poll methods may now
abort return EINTR (or a short transfer size) if a signal is received
while waiting to receive or send serial data. This behavior is required
by POSIX.
