Peter Hurley	ee3ad90be5	serial: 8250: Defer interrupt enable until fifos enabled ... An already-active sender can swamp the interrupt handler with "too much work" if the rx interrupts are enabled when the fifo is disabled and operating in single-byte mode. Defer rx and line status interrupt enable until after the fifos are enabled in set_termios(), but at least initialize the shadow IER value with the interrupts which will be enabled.

Peter Hurley	b6830f6df8	serial: 8250: Split base port operations from universal driver ... Refactor base port operations into new file; 8250_port.c. Legacy irq handling, RSA port support, port storage for universal driver, driver definition, module parameters and linkage remain in 8250_core.c The source file split and resulting modules is diagrammed below: 8250_core.c ====> 8250_core.c __ \ \ \ +-- 8250.ko (alias 8250_core) \ 8250_pnp.c __/ (universal driver) \ => 8250_port.c __ \ +-- 8250_base.ko 8250_dma.c __/ (port operations) Signed-off-by: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>	2015-07-23 17:43:01 -07:00
