Replace #include <semaphore.h> to #include <nuttx/semaphore.h>
...
Since the kernel side should call nxsem_xxx instead and remove the unused inclusion

drivers/serial/serial_dma.c: Still need reset xmit buffer when meet TCOFLUSH. This is an amendment to 8fb19a4359.

drivers/serial/serial_dma.c: Avoid uart_xmitchars_done() move the tail bigger then head. If ioctl(TCOFLUSH) occurs between uart_xmitchars_dma() and uart_xmitchars_done(), TCOFLUSH will reset xmit buffer, then uart_xmitchars_done() will move the 'tail' ahead of 'head', then sends lots of wrong data.

drivers/serial: The upper half serial driver configuration CONFIG_SERIAL_DMA used to enable DMA on both RX and TX streams. This was replaced with CONFIG_SERIAL_RXDMA and CONFIG_SERIAKL_TXDMA which will permit supporting DMA on only one or both streams.

drivers/serial: Add support for Ctrl-Z. This works just like the recently added Ctrl-C support except that SIGSTP is sent when the Ctrl-Z characters is encountered vs. SIGINT.

sched/signal: Add support for SIGINT in addition to SIGKILL. drivers/serial: Use SIGINT instead of SIGKILL when control-C is pressed.

Squashed commit of the following:
...
drivers/serial/Kconfig: It is no longer necessary to restrict Ctrl-C handling to the FLAT build
sched/signal: Add a new configuration option to select signal default actions, separate handling of signal default actions from both task startup logic and from the serial TTY Ctrl-C logic. Add a signal set in the group structure to keep track of what signals have been set to the default action. In dispatching signals in PROTECTED or KERNEL mode, use this signal set to determine if the default signal handler is attached and dispatch the signal in kernel mode for the default actions.

drivers/serial: Move head/tail pointer reset to uart_recvchars_dma since dma may be still transferring in the background.

Squashed commit of the following:
...
drivers/serial: Add Ctrl-C/Ctrl-X support. This is an initial working implementation that still requires that several details be resolved.
sched/task/task_start.c: Add default signal action to SIGKILL.
