2012-12-17Merge branch 'for-linus' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull user namespace changes from Eric Biederman: "While small this set of changes is very significant with respect to containers in general and user namespaces in particular. The user space interface is now complete. This set of changes adds support for unprivileged users to create user namespaces and as a user namespace root to create other namespaces. The tyranny of supporting suid root preventing unprivileged users from using cool new kernel features is broken. This set of changes completes the work on setns, adding support for the pid, user, mount namespaces. This set of changes includes a bunch of basic pid namespace cleanups/simplifications. Of particular significance is the rework of the pid namespace cleanup so it no longer requires sending out tendrils into all kinds of unexpected cleanup paths for operation. At least one case of broken error handling is fixed by this cleanup. The files under /proc/<pid>/ns/ have been converted from regular files to magic symlinks which prevents incorrect caching by the VFS, ensuring the files always refer to the namespace the process is currently using and ensuring that the ptrace_mayaccess permission checks are always applied. The files under /proc/<pid>/ns/ have been given stable inode numbers so it is now possible to see if different processes share the same namespaces. Through the David Miller's net tree are changes to relax many of the permission checks in the networking stack to allowing the user namespace root to usefully use the networking stack. Similar changes for the mount namespace and the pid namespace are coming through my tree. Two small changes to add user namespace support were commited here adn in David Miller's -net tree so that I could complete the work on the /proc/<pid>/ns/ files in this tree. Work remains to make it safe to build user namespaces and 9p, afs, ceph, cifs, coda, gfs2, ncpfs, nfs, nfsd, ocfs2, and xfs so the Kconfig guard remains in place preventing that user namespaces from being built when any of those filesystems are enabled. Future design work remains to allow root users outside of the initial user namespace to mount more than just /proc and /sys." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (38 commits) proc: Usable inode numbers for the namespace file descriptors. proc: Fix the namespace inode permission checks. proc: Generalize proc inode allocation userns: Allow unprivilged mounts of proc and sysfs userns: For /proc/self/{uid,gid}_map derive the lower userns from the struct file procfs: Print task uids and gids in the userns that opened the proc file userns: Implement unshare of the user namespace userns: Implent proc namespace operations userns: Kill task_user_ns userns: Make create_new_namespaces take a user_ns parameter userns: Allow unprivileged use of setns. userns: Allow unprivileged users to create new namespaces userns: Allow setting a userns mapping to your current uid. userns: Allow chown and setgid preservation userns: Allow unprivileged users to create user namespaces. userns: Ignore suid and sgid on binaries if the uid or gid can not be mapped userns: fix return value on mntns_install() failure vfs: Allow unprivileged manipulation of the mount namespace. vfs: Only support slave subtrees across different user namespaces vfs: Add a user namespace reference from struct mnt_namespace ...

Now that Chris Wilson demonstrated that the key for stability on early gen 2 is to simple _never_ exchange the physical backing storage of batch buffers I've tried a stab at a kernel solution. Doesn't look too nefarious imho, now that I don't try to be too clever for my own good any more. v2: After discussing the various techniques, we've decided to always blit batches on the suspect devices, but allow userspace to opt out of the kernel workaround assume full responsibility for providing coherent batches. The principal reason is that avoiding the blit does improve performance in a few key microbenchmarks and also in cairo-trace replays.

2012-12-17rbd: get rid of RBD_MAX_SEG_NAME_LENAlex Elder
RBD_MAX_SEG_NAME_LEN represents the maximum length of an rbd object name (i.e., one of the objects providing storage backing an rbd image). Another symbol, MAX_OBJ_NAME_SIZE, is used in the osd client code to define the maximum length of any object name in an osd request. Right now they disagree, with RBD_MAX_SEG_NAME_LEN being too big. There's no real benefit at this point to defining the rbd object name length limit separate from any other object name, so just get rid of RBD_MAX_SEG_NAME_LEN and use MAX_OBJ_NAME_SIZE in its place.

2012-12-17drm/i915: Prefer CRTC 'active' rather than 'enabled' during WM computationsChris Wilson
Only the intel_crtc->active is accurate at the point where we wish to perform WM computations, so use it instead of crtc->enabled. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2012-12-17drm/i915: Clear self-refresh watermarks when disabledChris Wilson
If we elect to disable self-refresh as they require too many FIFO entries, clear the values prior to writing them into the registers. If they are too large they may occupy more bits than available and so corrupt neighbouring WM values.

If difference value is negative number when current voltage of battery is larger than desc->fullbatt_uV, charger-manager return immediately because battery is fully charged.

git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6 Pull MFS update from Samuel Ortiz: "This is the MFD patch set for the 3.8 merge window. We have several new drivers, most of the time coming with their sub devices drivers: - Austria Microsystem's AS3711 - Nano River's viperboard - TI's TPS80031, AM335x TS/ADC, - Realtek's MMC/memstick card reader - Nokia's retu We also got some notable cleanups and improvements: - tps6586x got converted to IRQ domains. - tps65910 and tps65090 moved to the regmap IRQ API. - STMPE is now Device Tree aware. - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ APIs and a conversion to the recently added PWM framework. - sta2x11 gained regmap support. Then the rest is mostly tiny cleanups and fixes, among which we have Mark's wm5xxx and wm8xxx patchset." Far amount of annoying but largely trivial conflicts.

These devices are not available on other architectures, so let's limit them to omap. If the driver subsystem maintainers want to build test system wide changes without building for each target, it's easy to carry a test patch that just strips out the depends entries from Kconfig files.
