2016-02-21stm class: Fix unbalanced module/device refcountingAlexander Shishkin1-6/+14
STM code takes references to the stm device and its module for the duration of the character device's existence or the stm_source link. Dropping these references is not well balanced everywhere, which may lead to leaks. This patch balances the acquisition and releasing of these two references and annotates each site so that it's easier to verify correctness by reading the code.

2016-02-21stm class: Guard output assignment against concurrencyAlexander Shishkin2-0/+18
It is possible to concurrently assign the same output (a character device writer or an stm_source device) to different stm devices, which sets off a strategically placed warning in stm_output_assign(). To avoid this, use a spinlock to serialize (un)assignments between outputs and stm devices.

2016-02-21stm class: Fix unlocking braino in the error pathAlexander Shishkin1-4/+3
If an illegal attempt is made to unlink stm source device from an stm device, the stm device's link spinlock mistakenly remains locked. While this really shouldn't happen (there's a warning in place), the locking should remain in order so that we can still recover from this situation if it indeed does happen. This patch unifies the unlocking in the exit path of __stm_source_link_drop() to fix this.

2016-02-21stm class: Add heartbeat stm source deviceAlexander Shishkin3-0/+143
Heartbeat stm source may have multiple instances (for connecting to different stm devices). Each instance will send a periodic test message over its stm device when it is linked. This can be used for testing stm class framework, stm device drivers or as a heartbeat over the stm link.

2016-02-21stm class: dummy_stm: Create multiple devicesAlexander Shishkin1-9/+48
STM framework should be able to handle multiple STM devices at a time, each one with its own master allocation policy. This patch changes dummy_stm driver to create multiple STM sinks to help testing the framework.

2016-02-21stm class: Support devices with multiple instancesAlexander Shishkin1-3/+4
By convention, the name of the stm policy directory in configfs consists of the device name to which it applies and the actual policy name, separated by a dot. Now, some devices already have dots in their names that separate name of the actual device from its instance identifier. Such devices will result in two (or more, who can tell) dots in the policy directory name. Existing policy code, however, will treat the first dot as the one that separates device name from policy name, therefore failing the above case. This patch makes the last dot in the directory name be the separator, thus prohibiting dots from being used in policy names.

2016-02-21stm class: Use driver's packet callback return valueAlexander Shishkin2-7/+19
STM drivers provide a callback to generate/send individual STP packets; it also tells the stm core how many bytes of payload it has consumed. However, we would also need to use the negative space of this return value to communicate errors that occur during the packet generation, in which case the stm core will have to take appropriate action. For now, we need to account for the possibility that the stm driver may not support certain combinations of packet type/flags, in which case it is expected to signal an error.

2016-02-21intel_th: Use real device index in the node namesAlexander Shishkin1-3/+20
Most of the intel_th core supports multiple co-existing TH devices, except for output device nodes, where intel_th device id is hardcoded to be zero. Fix this by fetching the actual intel_th device id from the parent device's drvdata.

2016-02-21intel_th: Set root device's drvdata earlyAlexander Shishkin2-2/+2
Already during the subdevice initialization time, devices will need to reference Intel TH controller descriptor structure. This patch moves setting the drvdata from the pci glue to intel_th core, before subdevices are populated.

2016-02-21intel_th: sth: Sanitize packet callback's return valuesAlexander Shishkin1-3/+8
According to the stm class interface, the packet callback should return an error if it is asked to generate packets that it doesn't support. When it succeeds, it should return number of bytes consumed from its payload. Currently, for FLAG packet it mistakenly returns 1. This patch addresses these issues.

2016-02-21intel_th: Update scratchpad bits according to enabled output activityAlexander Shishkin4-4/+59
Intel TH implements a scratchpad register to indicate to the firmware and external debuggers what trace configuration is enabled so that everybody plays nicely together. The register is a bit field and the bit assignment convention is described in the developer's manual. This patch enables the driver to automatically set scratchpad register bits according to the output configuration that's enabled. Based on work by Yann Fouassier.

2016-02-21stm class: Fix master deallocation in device unregisteringChunyan Zhang1-1/+1
The device unregister path uses wrong master index range when it tries to free the allocated masters, it should, as does the rest of the stm class code, use real master IDs.

2016-02-13Merge branch 'akpm'(patches from Andrew)Linus Torvalds13-57/+62
Merge fixes from Andrew Morton: "10 fixes" The lockdep hlist conversion is in the locking tree too, waiting for the next merge window. Andrew thought it should go in now. I'll take it, since it fixes a real problem and looks trivially correct (famous last words). * emailed patches from Andrew Morton <akpm@linux-foundation.org>: arch/x86/Kconfig: CONFIG_X86_UV should depend on CONFIG_EFI mm: fix pfn_t vs highmem kernel/locking/lockdep.c: convert hash tables to hlists mm,thp: fix spellos in describing __HAVE_ARCH_FLUSH_PMD_TLB_RANGE mm,thp: khugepaged: call pte flush at the time of collapse mm/backing-dev.c: fix error path in wb_init() mm, dax: check for pmd_none() after split_huge_pmd() vsprintf: kptr_restrict is okay in IRQ when 2 mm: fix filemap.c kernel doc warning ubsan: cosmetic fix to Kconfig text
2016-02-12IB/mlx5: Fix RC transport send queue overhead computationLeon Romanovsky1-5/+7
Fix the RC QPs send queue overhead computation to take into account two additional segments in the WQE which are needed for registration operations. The ATOMIC and UMR segments can't coexist together, so chose maximum out of them. The commit 9e65dc371b5c ("IB/mlx5: Fix RC transport send queue overhead computation") was intended to update RC transport as commit messages states, but added the code to UC transport.
