2014-12-04acerhdf: Adding support for "manual mode"Peter Feuerer

2014-12-04Bluetooth: Split triggering of discovery commands into separate functionMarcel Holtmann
The actual process of compiling the correct HCI commands for triggering discovery is something that should be generic. So instead of mixing it into the Start Discover operation handling, split it out into its own function utilizing HCI request handling and just providing status in case of errors or invalid parameters.

2014-12-04Bluetooth: Use {start,stop}_discovery_complete handler for cmd_completeMarcel Holtmann
Sending the required cmd_complete for the management commands should be done in one place and not in multiple places. Especially for Start and Stop Discovery commands this is split into to sending it in case of failure from the complete handler, but in case of success from the event state update function triggering mgmt_discovering. This is way too convoluted and since hci_request serializes the HCI command processing, send the cmd_complete response from the complete handler for all cases.

2014-12-04arm64: add module support for alternatives fixupsAndre Przywara
Currently the kernel patches all necessary instructions once at boot time, so modules are not covered by this. Change the apply_alternatives() function to take a beginning and an end pointer and introduce a new variant (apply_alternatives_all()) to cover the existing use case for the static kernel image section. Add a module_finalize() function to arm64 to check for an alternatives section in a module and patch only the instructions from that specific area. Since that module code is not touched before the module initialization has ended, we don't need to halt the machine before doing the patching in the module's code.

2014-12-04arm64: perf: Prevent wraparound during overflowDaniel Thompson
If the overflow threshold for a counter is set above or near the 0xffffffff boundary then the kernel may lose track of the overflow causing only events that occur *after* the overflow to be recorded. Specifically the problem occurs when the value of the performance counter overtakes its original programmed value due to wrap around. Typical solutions to this problem are either to avoid programming in values likely to be overtaken or to treat the overflow bit as the 33rd bit of the counter. Its somewhat fiddly to refactor the code to correctly handle the 33rd bit during irqsave sections (context switches for example) so instead we take the simpler approach of avoiding values likely to be overtaken. We set the limit to half of max_period because this matches the limit imposed in __hw_perf_event_init(). This causes a doubling of the interrupt rate for large threshold values, however even with a very fast counter ticking at 4GHz the interrupt rate would only be ~1Hz.

2014-12-04PM / Domains: Initial PM clock support for genpdUlf Hansson
It's quite common for PM domains to use PM clocks. Typically from SOC specific code, the per device PM clock list is created and pm_clk_suspend|resume() are invoked to handle clock gating/ungating. A step towards consolidation is to integrate PM clock support into genpd, which is what this patch does. In this initial step, the calls to the pm_clk_suspend|resume() are handled within genpd, but the per device PM clock list still needs to be created from SOC specific code. It seems reasonable to have gendp to handle that as well, but that left to future patches to address. It's not every users of genpd that are keen on using PM clocks, thus we need to provide this a configuration option for genpd. Therefore let's add flag field in the genpd struct to keep this information and define a new GENDP_FLAG_PM_CLK bit for it.

2014-12-04cpuidle: add MAINTAINERS entry for ARM Exynos cpuidle driverBartlomiej Zolnierkiewicz
Since there has been quite a lot of development going on for ARM Exynos cpuidle driver recently I would like to add separate MAINTAINERS entry for it and add myself as the primary maintainer. The merging process would remain (almost) unchanged with patches going (with my Ack) through Daniel's or Kukjin's tree.
