kgdboc,input: Fix regression with keyboard release key and early debugging

2010-12-14T04:44:03Z

The commit 111c182340cd22e238ab1cc6564df336c6ebd7cb (kgdboc: reset input devices (keyboards) when exiting debugger) introduced a regression in early debugging such that you get a kernel oops on continue (with the go command) if you boot a kernel with: earlyprintk=vga ekgdboc=kbd kgdbwait The restore kgdboc_restore_input() routine schedules work for the purpose of sending key release events for any keys that were in the depressed state prior to entering the kernel debugger. A simple fix to the crash is to not invoke the schedule_work() if the kernel system_state is anything other than SYSTEM_RUNNING.

serial: mfd: adjust the baud rate setting

2010-12-01T01:32:32Z

Previous baud rate setting code only has been tested with 3.5M/9600/ 115200/230400/460800 bps, and recently we got a 3M bps device to test, which needs to modify current MUL register setting, and with this patch 2.5M/2M/1.5M/1M/0.5M should also work as they just use a MUL value scale down from 3M's. Also got some reference register setting from silicon guys for different baud rates, which tries to keep the pre-scalar register value to 16.

BKL: remove extraneous #include

2010-11-17T16:59:32Z

The big kernel lock has been removed from all these files at some point, leaving only the #include. Remove this too as a cleanup. Signed-off-by: Arnd Bergmann Signed-off-by: Linus Torvalds

serial8250: Mark console as CON_ANYTIME

2010-11-16T21:29:54Z

While trying to debug a cpu-hotplug issue I noticed printk() stopped working once the cpu got marked offline, since the 8250 serial console doesn't have any per-cpu resources the CON_ANYTIME bit is the safe and documented way to make it work again.

serial: bfin_5xx: grab port lock before making port termios changes

2010-11-11T19:06:08Z

The port lock exists to protect these resources, so we need to grab it before making changes. Signed-off-by: Sonic Zhang Signed-off-by: Mike Frysinger Signed-off-by: Greg Kroah-Hartman

serial: bfin_5xx: disable CON_PRINTBUFFER for consoles

2010-11-11T19:06:08Z

If we are using early serial, don't let the normal console rewind the log buffer, since that causes things to be printed multiple times. Signed-off-by: Sonic Zhang Signed-off-by: Mike Frysinger Signed-off-by: Greg Kroah-Hartman
