Keyboard handler should not attempt to traverse handler->h_list on its own, without any locking, otherwise it races with registering and unregistering of input handles which leads to crashes. Introduce input_handler_for_each_handle() helper that allows safely iterate over all handles attached to a particular handler and switch keyboard handler to use it.

We need to read and report gpio state when we bind the driver to the device and upon resume so that userspace has correct state of the switches (and keys but they are less important since, even if they are happened to be pressed, we'd expect them to be released fairly soon).

Keyboard input handler is multiplexing events form all keyboard-like devices in the system. Because of that per-device lock provided by input core is not enough to prevent clashes in ked_event() and we need our own lock to ensure that only one thread at a time executing kbd_event().

S3C24XX touchscreen driver, originally written by Arnaud Patard and other contributors. The driver has had substantial testing as well as a number of tidying up passes done by Ben Dooks, as noted: - added kernel-doc comments to most of the routines - removed old code from pre adc framework days - updated device probe code to use platform id list matching - cleaned up debug, since printk() now has timestamp feature - ensure code uses dev_() reporting macros where necessary - remove ABS_PRESSURE reporting, tslib can be fixed - ensure timer is removed on driver exit - move to using dev_pmops for power management Signed-off-by: NArnaud Patard <arnaud.patard@rtp-net.org> Signed-off-by: NBen Dooks <ben@simtec.co.uk> Signed-off-by: NSimtec Linux Team <linux@simtec.co.uk> Signed-off-by: NDmitry Torokhov <dtor@mail.ru>

The touchpad on Acer Aspire 5720, 5520 and some other Aspire models (signature 0x73, 0x02, 0x50) has a button that can be rocked in 4 different directions. Make the driver to generate BTN_0..BTN_3 events in response. The Synaptics driver by default maps BTN_0 and BTN_1 to up and down, so there should be no visible changes with the old setup that generated BTN_FORWARD and BTN_BACK (also mapped to up and down).

Sysfs entry for reading and setting of the polling interval. If the interval is set to 0, polling is stopped. Polling is restarted when interval is changed to non-zero. sysfs entries: poll = current polling interval in msec (RW) max = max allowed polling interval (RO) min = min allowed polling interval (RO) Minimum and maximum limit for interval can be set while setting up the device. Interval can be adjusted even if the input device is not currently open.

nr_processes() returns the sum of the per cpu counter process_counts for all online CPUs. This counter is incremented for the current CPU on fork() and decremented for the current CPU on exit(). Since a process does not necessarily fork and exit on the same CPU the process_count for an individual CPU can be either positive or negative and effectively has no meaning in isolation. Therefore calculating the sum of process_counts over only the online CPUs omits the processes which were started or stopped on any CPU which has since been unplugged. Only the sum of process_counts across all possible CPUs has meaning. The only caller of nr_processes() is proc_root_getattr() which calculates the number of links to /proc as stat->nlink = proc_root.nlink + nr_processes(); You don't have to be all that unlucky for the nr_processes() to return a negative value leading to a negative number of links (or rather, an apparently enormous number of links). If this happens then you can get failures where things like "ls /proc" start to fail because they got an -EOVERFLOW from some stat() call. Example with some debugging inserted to show what goes on: # ps haux|wc -l nr_processes: CPU0: 90 nr_processes: CPU1: 1030 nr_processes: CPU2: -900 nr_processes: CPU3: -136 nr_processes: TOTAL: 84 proc_root_getattr. nlink 12 + nr_processes() 84 = 96 84 # echo 0 >/sys/devices/system/cpu/cpu1/online # ps haux|wc -l nr_processes: CPU0: 85 nr_processes: CPU2: -901 nr_processes: CPU3: -137 nr_processes: TOTAL: -953 proc_root_getattr. nlink 12 + nr_processes() -953 = -941 75 # stat /proc/ nr_processes: CPU0: 84 nr_processes: CPU2: -901 nr_processes: CPU3: -137 nr_processes: TOTAL: -954 proc_root_getattr. nlink 12 + nr_processes() -954 = -942 File: `/proc/' Size: 0 Blocks: 0 IO Block: 1024 directory Device: 3h/3d Inode: 1 Links: 4294966354 Access: (0555/dr-xr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2009-11-03 09:06:55.000000000 +0000 Modify: 2009-11-03 09:06:55.000000000 +0000 Change: 2009-11-03 09:06:55.000000000 +0000 I'm not 100% convinced that the per_cpu regions remain valid for offline CPUs, although my testing suggests that they do. If not then I think the correct solution would be to aggregate the process_count for a given CPU into a global base value in cpu_down(). This bug appears to pre-date the transition to git and it looks like it may even have been present in linux-2.6.0-test7-bk3 since it looks like the code Rusty patched in http://lwn.net/Articles/64773/ was already wrong.
