2012-06-12target: Add TFO->put_session() caller for HW fabric session shutdownJoern Engel1-0/+1
This patch adds an optional target_core_fabric_ops->put_session() caller within the existing target_put_session() code path. This is required by tcm_qla2xxx code in order to invoke it's own fabric specific session shutdown handler using se_session->sess_kref.

2012-06-12bonding: Fix corrupted queue_mappingEric Dumazet1-2/+5
In the transmit path of the bonding driver, skb->cb is used to stash the skb->queue_mapping so that the bonding device can set its own queue mapping. This value becomes corrupted since the skb->cb is also used in __dev_xmit_skb. When transmitting through bonding driver, bond_select_queue is called from dev_queue_xmit. In bond_select_queue the original skb->queue_mapping is copied into skb->cb (via bond_queue_mapping) and skb->queue_mapping is overwritten with the bond driver queue. Subsequently in dev_queue_xmit, __dev_xmit_skb is called which writes the packet length into skb->cb, thereby overwriting the stashed queue mappping. In bond_dev_queue_xmit (called from hard_start_xmit), the queue mapping for the skb is set to the stashed value which is now the skb length and hence is an invalid queue for the slave device. If we want to save skb->queue_mapping into skb->cb[], best place is to add a field in struct qdisc_skb_cb, to make sure it wont conflict with other layers (eg : Qdiscc, Infiniband...) This patchs also makes sure (struct qdisc_skb_cb)->data is aligned on 8 bytes : netem qdisc for example assumes it can store an u64 in it, without misalignment penalty. Note : we only have 20 bytes left in (struct qdisc_skb_cb)->data[]. The largest user is CHOKe and it fills it. Based on a previous patch from Tom Herbert.

2012-06-12drm: increase DRM_OBJECT_MAX_PROPERTY to 24Paulo Zanoni1-1/+1
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.

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>

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 Gorcunov1-4/+6
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.

2012-06-06rcu: Precompute RCU_FAST_NO_HZ timer offsetsPaul E. McKenney2-3/+5
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.

2012-06-05NFS: Fix a commit bugTrond Myklebust1-0/+2
The new commit code fails to copy the verifier into the wb_verf field of _all_ the nfs_page structures; it only copies it into the first entry. The consequence is that most requests end up failing to match in nfs_commit_release. Fix is to copy the verifier into the req->wb_verf field in nfs_write_completion.

2012-06-05Merge branch 'i2c-embedded/for-current' of git://git.pengutronix.de/git/wsa/linuxLinus Torvalds1-0/+41
Pull embedded i2c update from Wolfram Sang: "This only contains one new driver which had multiple dependencies (pinctrl, i2c-mux-rework, new devm_* functions), so I decided to wait for rc1. Plus, it had to wait a little for the ack of a devicetree maintainer since the bindings were not trivial enough for me to pass through. So, given that, I hope there is still something like the "new driver rule", so we could have the driver in 3.5 and people can start using it. That would make merging support for some boards easier for 3.6 since the dependency on this driver is gone then." * 'i2c-embedded/for-current' of git://git.pengutronix.de/git/wsa/linux: i2c: Add generic I2C multiplexer using pinctrl API

2012-06-05radix-tree: fix contiguous iteratorKonstantin Khlebnikov1-1/+4
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 Myklebust1-0/+1
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 Clausen4-0/+84
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 Clausen1-0/+64
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.
