2012-06-12drm: increase DRM_OBJECT_MAX_PROPERTY to 24Paulo Zanoni
Before Kernel 3.5, no one was checking for the return value of drm_connector_attach_property, so we never noticed that we were unable to create some properties. Commit "drm: WARN() when drm_connector_attach_property fails" added a WARN when we fail to create a property, and the transition from "connector properties" to "object properties" changed the warning message a little bit. On i915 machines with many TV connectors we hit the maximum number of properties (since each TV connector uses a lot of properties), so we get a few backtraces in our logs. This commit increases the maximum number of properties to 24 hoping we'll have enough room for everybody. Chris suggested that we convert this code to "lists", but I believe this conversion can come after we make sure people's dmesgs are not spammed by our driver.

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/urgent Merge RCU fixes from Paul E. McKenney: " This series has four patches, the major point of which is to eliminate some slowdowns (including boot-time slowdowns) resulting from some RCU_FAST_NO_HZ changes. The issue with the changes is that posting timers from the idle loop has no effect if the CPU has entered dyntick-idle mode because the CPU has already computed its wakeup time, and posting a timer does not cause it to be recomputed. The short-term fix is for RCU to precompute the timeout value so that the CPU's calculation is correct. " Signed-off-by: Ingo Molnar <mingo@kernel.org>

I originally sent this patch to <trivial@kernel.org>, but Jiri Kosina did not feel that this is fully appropriate for the trivial tree.

Commit 026cee0086fe1df4cf74691cf273062cc769617d "params: <level>_initcall-like kernel parameters" set old-style module parameters to level 0. And we call those level 0 calls where we used to, early in start_kernel(). We also loop through the initcall levels and call the levelled module_params before the corresponding initcall. Unfortunately level 0 is early_init(), so we call the standard module_param calls twice. (Turns out most things don't care, but at least ubi.mtd does).

2012-06-07c/r: prctl: add ability to get clear_tid_addressCyrill Gorcunov
Zero is written at clear_tid_address when the process exits. This functionality is used by pthread_join(). We already have sys_set_tid_address() to change this address for the current task but there is no way to obtain it from user space. Without the ability to find this address and dump it we can't restore pthread'ed apps which call pthread_join() once they have been restored. This patch introduces the PR_GET_TID_ADDRESS prctl option which allows the current process to obtain own clear_tid_address. This feature is available iif CONFIG_CHECKPOINT_RESTORE is set.

2012-06-07rcu: Precompute RCU_FAST_NO_HZ timer offsetsPaul E. McKenney
When a CPU is entering dyntick-idle mode, tick_nohz_stop_sched_tick() calls rcu_needs_cpu() see if RCU needs that CPU, and, if not, computes the next wakeup time based on the timer wheels. Only later, when actually entering the idle loop, rcu_prepare_for_idle() will be invoked. In some cases, rcu_prepare_for_idle() will post timers to wake the CPU back up. But all for naught: The next wakeup time for the CPU has already been computed, and posting a timer afterwards does not force that wakeup time to be recomputed. This means that rcu_prepare_for_idle()'s have no effect. This is not a problem on a busy system because something else will wake up the CPU soon enough. However, on lightly loaded systems, the CPU might stay asleep for a considerable length of time. If that CPU has a callback that the rest of the system is waiting on, the system might run very slowly or (in theory) even hang. This commit avoids this problem by having rcu_needs_cpu() give tick_nohz_stop_sched_tick() an estimate of when RCU will need the CPU to wake back up, which tick_nohz_stop_sched_tick() takes into account when programming the CPU's wakeup time. An alternative approach is for rcu_prepare_for_idle() to use hrtimers instead of normal timers, but timers are much more efficient than are hrtimers for frequently and repeatedly posting and cancelling a given timer, which is exactly what RCU_FAST_NO_HZ does.

This patch fixes bug in macro radix_tree_for_each_contig(). If radix_tree_next_slot() sees NULL in next slot it returns NULL, but following radix_tree_next_chunk() switches iterating into next chunk. As result iterating becomes non-contiguous and breaks vfs "splice" and all its users.

2012-06-05NFSv4: Fix an Oops in the open recovery codeTrond Myklebust
The open recovery code does not need to request a new value for the mdsthreshold, and so does not allocate a struct nfs4_threshold. The problem is that encode_getfattr_open() will still request an mdsthreshold, and so we end up Oopsing in decode_attr_mdsthreshold. This patch fixes encode_getfattr_open so that it doesn't request an mdsthreshold when the caller isn't asking for one. It also fixes decode_attr_mdsthreshold so that it errors if the server returns an mdsthreshold that we didn't ask for (instead of Oopsing).

2012-06-05staging:iio: Move DAC drivers out of stagingLars-Peter Clausen
The IIO DAC drivers are in a reasonably good shape. They all make use of channel spec and non of them provides non-documented sysfs attributes. Code style should be OK as well, both checkpatch and coccicheck only report trivial issues. So lets move the whole folder out of staging.

2012-06-05iio: Add helper functions for enum style channel attributesLars-Peter Clausen
We often have the case were we do have a enum style channel attribute. These attributes have in common that they are a list of string values which usually map in a 1-to-1 fashion to integer values. This patch implements some common helper code for implementing enum style channel attributes using extended channel attributes. The helper functions take care of converting between the string and integer values, as well providing a function for "_available" attributes which list all available enum items.
