2016-06-28clocksource/drivers/atmel-pit: Convert init function to return errorDaniel Lezcano
The init functions do not return any error. They behave as the following: - panic, thus leading to a kernel crash while another timer may work and make the system boot up correctly or - print an error and let the caller unaware if the state of the system Change that by converting the init functions to return an error conforming to the CLOCKSOURCE_OF_RET prototype. Proper error handling (rollback, errno value) will be changed later case by case, thus this change just return back an error or success in the init function.

2016-06-28clocksource/drivers/clksrc-probe: Introduce init functions with return codeDaniel Lezcano
Currently, the clksrc-probe is not able to handle any error from the init functions. There are different issues with the current code: - the code is duplicated in the init functions by writing error - every driver tends to panic in its own init function - counting the number of clocksources is not reliable This patch adds another table to store the functions returning an error. The table is temporary while we convert all the drivers to return an error and will disappear. Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>

Add clocksource and clockevent driver from dual RPS timer. The HW provides a dual one-shot or periodic 24bit timers, the drivers set the first one as tick event source and the second as a continuous scheduler clock source. The timer can use 1, 16 or 256 as pre-dividers, thus the clocksource uses 16 by default.

2016-06-05devpts: Make each mount of devpts an independent filesystem.Eric W. Biederman
The /dev/ptmx device node is changed to lookup the directory entry "pts" in the same directory as the /dev/ptmx device node was opened in. If there is a "pts" entry and that entry is a devpts filesystem /dev/ptmx uses that filesystem. Otherwise the open of /dev/ptmx fails. The DEVPTS_MULTIPLE_INSTANCES configuration option is removed, so that userspace can now safely depend on each mount of devpts creating a new instance of the filesystem. Each mount of devpts is now a separate and equal filesystem. Reserved ttys are now available to all instances of devpts where the mounter is in the initial mount namespace. A new vfs helper path_pts is introduced that finds a directory entry named "pts" in the directory of the passed in path, and changes the passed in path to point to it. The helper path_pts uses a function path_parent_directory that was factored out of follow_dotdot. In the implementation of devpts: - devpts_mnt is killed as it is no longer meaningful if all mounts of devpts are equal. - pts_sb_from_inode is replaced by just inode->i_sb as all cached inodes in the tty layer are now from the devpts filesystem. - devpts_add_ref is rolled into the new function devpts_ptmx. And the unnecessary inode hold is removed. - devpts_del_ref is renamed devpts_release and reduced to just a deacrivate_super. - The newinstance mount option continues to be accepted but is now ignored. In devpts_fs.h definitions for when !CONFIG_UNIX98_PTYS are removed as they are never used. Documentation/filesystems/devices.txt is updated to describe the current situation. This has been verified to work properly on openwrt-15.05, centos5, centos6, centos7, debian-6.0.2, debian-7.9, debian-8.2, ubuntu-14.04.3, ubuntu-15.10, fedora23, magia-5, mint-17.3, opensuse-42.1, slackware-14.1, gentoo-20151225 (13.0?), archlinux-2015-12-01. With the caveat that on centos6 and on slackware-14.1 that there wind up being two instances of the devpts filesystem mounted on /dev/pts, the lower copy does not end up getting used.
