2013-08-03tracing: Fix trace_dump_stack() proto when CONFIG_TRACING is not setDhaval Giani1-1/+1
When CONFIG_TRACING is not enabled, the stub prototype for trace_dump_stack() is incorrect. It has (void) when it should be (int).

2013-08-03tracing: Fix fields of struct trace_iterator that are zeroed by mistakeAndrew Vagin1-4/+6
tracing_read_pipe zeros all fields bellow "seq". The declaration contains a comment about that, but it doesn't help. The first field is "snapshot", it's true when current open file is snapshot. Looks obvious, that it should not be zeroed. The second field is "started". It was converted from cpumask_t to cpumask_var_t (v2.6.28-4983-g4462344), in other words it was converted from cpumask to pointer on cpumask. Currently the reference on "started" memory is lost after the first read from tracing_read_pipe and a proper object will never be freed. The "started" is never dereferenced for trace_pipe, because trace_pipe can't have the TRACE_FILE_ANNOTATE options.

2013-08-03fbdev: simplefb: add init through platform_dataDavid Herrmann1-0/+56
If we create proper platform-devices in x86 boot-code, we can use simplefb for VBE or EFI framebuffers, too. However, there is normally no OF support so we introduce a platform_data object so x86 boot-code can pass the parameters via plain old platform-data. This also removes the OF dependency as it is not needed. The headers provide proper dummies for the case OF is disabled. Furthermore, we move the FORMAT-definitions to the common platform header so initialization code can use it to transform "struct screen_info" to the right format-name.

Fix from Colin Cross addresses this by adding a process flag to mark the hibernate/suspend process to inform the freezer that that process should be ignored. - One of the recent cpufreq reverts uncovered a problem in the core causing the cpufreq driver module refcount to become negative after a system suspend-resume cycle. Fix from Rafael J Wysocki. - The evaluation of the ACPI battery _BIX method has never worked correctly, because the commit that added support for it forgot to take the "Revision" field in the return package into account.

2013-08-01net: add a temporary sanity check in skb_orphan()Eric Dumazet1-0/+2
David suggested to add a BUG_ON() to catch if some layer sets skb->sk pointer without a corresponding destructor. As skb can sit in a queue, it's mandatory to make sure the socket cannot disappear, and it's usually done by taking a reference on the socket, then releasing it from the skb destructor. This patch is a follow-up to commit c34a761231b5 ("net: skb_orphan() changes") and will be reverted after catching all possible offenders if any.

2013-08-01vmpressure: make sure there are no events queued after memcg is offlinedMichal Hocko1-0/+1
vmpressure is called synchronously from reclaim where the target_memcg is guaranteed to be alive but the eventfd is signaled from the work queue context. This means that memcg (along with vmpressure structure which is embedded into it) might go away while the work item is pending which would result in use-after-release bug. We have two possible ways how to fix this. Either vmpressure pins memcg before it schedules vmpr->work and unpin it in vmpressure_work_fn or explicitely flush the work item from the css_offline context (as suggested by Tejun). This patch implements the later one and it introduces vmpressure_cleanup which flushes the vmpressure work queue item item. It hooks into mem_cgroup_css_offline after the memcg itself is cleaned up.

2013-08-01mlx5_core: Implement new initialization sequenceEli Cohen2-1/+23
Introduce enbale_hca and disable_hca commands to signify when the driver starts or ceases to operate on the device. In addition the driver will use boot and init pages count; boot pages is required to allow firmware to complete boot commands and the other to complete init hca. Command interface revision is bumped to 4 to enforce using supported firmware. This patch breaks compatibility with old versions of firmware (< 4); however, the first GA firmware we will publish will support version 4 so this should not be a problem.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== This series contains updates to ixgbe and pci. The first patch for ixgbe from Greg Rose is the second submission. The first submission of "ixgbe: Retain VLAN filtering in promiscuous + VT mode" had a typo, which Joe Perches pointed out and is fixed in this submission. Alex updates the ixgbe driver to use the generic helper pci_vfs_assigned instead of the driver specific function ixgbe_vfs_are_assigned. Don Skidmore provides 4 patches for ixgbe, the first being a fix for flow control ethtool reporting. Originally ixgbe_device_supports_autoneg_fc() was expected to be called by only copper devices, which lead to false information being displayed via ethtool. Two other patches add support for fixed fiber for SFP+ devices and the addition of a quad-port x520 adapter. The last patch simply bumps the driver version. Emil Tantilov provides 3 fixes for ixgbe, two of which resolve semaphore lock issues. The third fix resolves several issues in the previous implementation of the SFF data dumps of SFP+ modules. The remaining ixgbe and pci patches are from Jacob Keller. The pci patches exposes bus speed, link speed and bus width so that drivers can take advantage of this information. In addition, adds a pci function which obtains minimum link width and speed. Jacob also provides the ixgbe patch to incorporate the pci function. He provides a patch that fixes a lockdep issue created due to ixgbe_ptp_stop always running cancel_work_sync even if the work item had not been created properly with INIT_WORK. This issue was found and reported by Stephen Hemminger. -v2- * fix patch 3 to be a bool function based on David Miller's feedback * fix patch 4 debug message based on David Miller's feedback * fix patch 8 moved the extern declarations to pci.h based on Bjorn Helgaas's feedback * fix patch 11 update the error message to include encoding loss based * fix patch 8/9/10 title based on Bjorn's feedback ==================== Signed-off-by: David S.

2013-07-31tracing: trace_remove_event_call() should fail if call/file is in useOleg Nesterov1-1/+1
Change trace_remove_event_call(call) to return the error if this call is active. This is what the callers assume but can't verify outside of the tracing locks. Both trace_kprobe.c/trace_uprobe.c need the additional changes, unregister_trace_probe() should abort if trace_remove_event_call() fails. The caller is going to free this call/file so we must ensure that nobody can use them after trace_remove_event_call() succeeds. debugfs should be fine after the previous changes and event_remove() does TRACE_REG_UNREGISTER, but still there are 2 reasons why we need the additional checks: - There could be a perf_event(s) attached to this tp_event, so the patch checks ->perf_refcount. - TRACE_REG_UNREGISTER can be suppressed by FTRACE_EVENT_FL_SOFT_MODE, so we simply check FTRACE_EVENT_FL_ENABLED protected by event_mutex.

2013-07-31HID: input: generic hidinput_input_event handlerDavid Herrmann1-0/+1
The hidinput_input_event() callback converts input events written from userspace into HID reports and sends them to the device. We currently implement this in every HID transport driver, even though most of them do the same. This provides a generic hidinput_input_event() implementation which is mostly copied from usbhid. It uses a delayed worker to allow multiple LED events to be collected into a single output event. We use the custom ->request() transport driver callback to allow drivers to adjust the outgoing report and handle the request asynchronously. If no custom ->request() callback is available, we fall back to the generic raw output report handler (which is synchronous). Drivers can still provide custom hidinput_input_event() handlers (see logitech-dj) if the generic implementation doesn't fit their needs.

2013-07-31regulator: core: Provide hints to the core about optional suppliesMark Brown1-1/+17
While the majority of supplies on devices are mandatory and can't be physically omitted for electrical reasons some devices do have optional supplies and need to know if they are missing, MMC being the most common of these. Currently the core accurately reports all errors when regulators are requested since it does not know if the supply is one that must be provided even if by a regulator software does not know about or if it is one that may genuinely be disconnected. In order to allow this behaviour to be changed and stub regulators to be provided in the former case add a new regulator request function regulator_get_optional() which provides a hint to the core that the regulator may genuinely not be connected. Currently the implementation is identical to the current behaviour, future patches will add support in the core for returning stub regulators in the case where normal regulator_get() fails and the board has requested it.

2013-07-31PCI: Add function to obtain minimum link width and speedJacob Keller1-0/+2
A PCI Express device can potentially report a link width and speed which it will not properly fulfill due to being plugged into a slower link higher in the chain. This function walks up the PCI bus chain and calculates the minimum link width and speed of this entire chain. This can be useful to enable a device to determine if it has enough bandwidth for optimum functionality.

2013-07-31net: add ndo to get id of physical port of the deviceJiri Pirko1-0/+20
This patch adds a ndo for getting physical port of the device. Driver which is aware of being virtual function of some physical port should implement this ndo. This is applicable not only for IOV, but for other solutions (NPAR, multichannel) as well. Basically if there is possible to have multiple netdevs on the single hw port.

ADC is ideally expected to work at a frequency of 3MHz. The present code had a check, which returned error if the frequency went below the threshold value. But since AM335x supports various working frequencies, this check is not required. Now the code just uses the internal ADC clock divider to set the ADC frequency w.r.t the sys clock.
