2015-12-01clk: sunxi: Add sun9i A80 cpus (cpu special) clock supportChen-Yu Tsai1-0/+1
The "cpus" clock is the clock for the embedded processor in the A80. It is also part of the PRCM clock tree. This clock includes a pre- divider on one of its inputs. For now we are using a custom clock driver for it. In the future we may want to develop a generalized driver for these types of clocks, which also includes the AHB clock driver on sun[5678]i.

2015-11-30dmaengine: ti-dma-crossbar: dra7: Support for reserving DMA event rangesPeter Ujfalusi1-0/+6
In eDMA the events are directly mapped to a DMA channel (for example DMA event 14 can only be handled by DMA channel 14). If the memcpy is enabled on the eDMA, there is a possibility that the crossbar driver would assign DMA event number already allocated in eDMA for memcpy. Furthermore the eDMA can be shared with DSP in which case the crossbar driver should also avoid mapping xbar events to DSP used event numbers (or channels).

2015-11-25KVM: x86: MMU: Consolidate BUG_ON checks for reverse-mapped sptesTakuya Yoshikawa1-2/+2
At some call sites of rmap_get_first() and rmap_get_next(), BUG_ON is placed right after the call to detect unrelated sptes which must not be found in the reverse-mapping list. Move this check in rmap_get_first/next() so that all call sites, not just the users of the for_each_rmap_spte() macro, will be checked the same way. One thing to keep in mind is that kvm_mmu_unlink_parents() also uses rmap_get_first() to handle parent sptes. The change will not break it because parent sptes are present, at least until drop_parent_pte() actually unlinks them, and not mmio-sptes.

2015-11-25kvm/x86: Hyper-V synthetic interrupt controllerAndrey Smetanin1-0/+19
SynIC (synthetic interrupt controller) is a lapic extension, which is controlled via MSRs and maintains for each vCPU - 16 synthetic interrupt "lines" (SINT's); each can be configured to trigger a specific interrupt vector optionally with auto-EOI semantics - a message page in the guest memory with 16 256-byte per-SINT message slots - an event flag page in the guest memory with 16 2048-bit per-SINT event flag areas The host triggers a SINT whenever it delivers a new message to the corresponding slot or flips an event flag bit in the corresponding area. The guest informs the host that it can try delivering a message by explicitly asserting EOI in lapic or writing to End-Of-Message (EOM) MSR. The userspace (qemu) triggers interrupts and receives EOM notifications via irqfd with resampler; for that, a GSI is allocated for each configured SINT, and irq_routing api is extended to support GSI-SINT mapping. Changes v4: * added activation of SynIC by vcpu KVM_ENABLE_CAP * added per SynIC active flag * added deactivation of APICv upon SynIC activation Changes v3: * added KVM_CAP_HYPERV_SYNIC and KVM_IRQ_ROUTING_HV_SINT notes into docs Changes v2: * do not use posted interrupts for Hyper-V SynIC AutoEOI vectors * add Hyper-V SynIC vectors into EOI exit bitmap * Hyper-V SyniIC SINT msr write logic simplified Signed-off-by: Andrey Smetanin <asmetanin@virtuozzo.com> Reviewed-by: Roman Kagan <rkagan@virtuozzo.com> Signed-off-by: Denis V.

2015-11-24Merge branch 'for-linus' of git://git.kernel.dk/linux-blockLinus Torvalds1-0/+3
Pull block layer fixes from Jens Axboe: "A round of fixes/updates for the current series. This looks a little bigger than it is, but that's mainly because we pushed the lightnvm enabled null_blk change out of the merge window so it could be updated a bit. The rest of the volume is also mostly lightnvm. In particular: - Lightnvm. Various fixes, additions, updates from Matias and Javier, as well as from Wenwei Tao. - NVMe: - Fix for potential arithmetic overflow from Keith. - Also from Keith, ensure that we reap pending completions from a completion queue before deleting it. Fixes kernel crashes when resetting a device with IO pending. - Various little lightnvm related tweaks from Matias. - Fixup flushes to go through the IO scheduler, for the cases where a flush is not required. Fixes a case in CFQ where we would be idling and not see this request, hence not break the idling. From Jan Kara. - Use list_{first,prev,next} in elevator.c for cleaner code. From Gelian Tang. - Fix for a warning trigger on btrfs and raid on single queue blk-mq devices, where we would flush plug callbacks with preemption disabled. From me. - A mac partition validation fix from Kees Cook. - Two merge fixes from Ming, marked stable. A third part is adding a new warning so we'll notice this quicker in the future, if we screw up the accounting. - Cleanup of thread name/creation in mtip32xx from Rasmus Villemoes" * 'for-linus' of git://git.kernel.dk/linux-block: (32 commits) blk-merge: warn if figured out segment number is bigger than nr_phys_segments blk-merge: fix blk_bio_segment_split block: fix segment split blk-mq: fix calling unplug callbacks with preempt disabled mac: validate mac_partition is within sector mtip32xx: use formatting capability of kthread_create_on_node NVMe: reap completion entries when deleting queue lightnvm: add free and bad lun info to show luns lightnvm: keep track of block counts nvme: lightnvm: use admin queues for admin cmds lightnvm: missing free on init error lightnvm: wrong return value and redundant free null_blk: do not del gendisk with lightnvm null_blk: use device addressing mode null_blk: use ppa_cache pool NVMe: Fix possible arithmetic overflow for max segments blk-flush: Queue through IO scheduler when flush not required null_blk: register as a LightNVM device elevator: use list_{first,prev,next}_entry lightnvm: cleanup queue before target removal ...

2015-11-23PM / OPP: Rename OPP nodes as opp@<opp-hz>Viresh Kumar1-19/+19
It would be better to name OPP nodes as opp@<opp-hz> as that will ensure that multiple DT nodes don't contain the same frequency. Of course we expect the writer to name the node with its opp-hz frequency and not any other frequency. And that will let the compile error out if multiple nodes are using the same opp-hz frequency.

2015-11-23PM / OPP: Add {opp-microvolt|opp-microamp}-<name> bindingViresh Kumar1-0/+47
Depending on the version of hardware or its properties, which are only known at runtime, various properties of the OPP can change. For example, an OPP with frequency 1.2 GHz, may have different voltage/current requirements based on the version of the hardware it is running on. In order to not replicate the same OPP tables for varying values of all such fields, this commit introduces the concept of opp-property-<name>. The <name> can be chosen by the platform at runtime, and OPPs will be initialized depending on that name string. Currently support is extended for the following properties: - opp-microvolt-<name> - opp-microamp-<name> If the name string isn't provided by the platform, or if it is provided but doesn't match the properties present in the OPP node, we will fall back to the original properties without the -<name> string, if they are available.

2015-11-23PM / OPP: Add "opp-supported-hw" bindingViresh Kumar1-0/+65
We may want to enable only a subset of OPPs, from the bigger list of OPPs, based on what version of the hardware we are running on. This would enable us to not duplicate OPP tables for every version of the hardware we support. To enable that, this patch defines a new property 'opp-supported-hw'. It can support any number of hierarchy levels of the versions the hardware follows. And based on the selected hardware versions, we can pick only the relevant OPPs at runtime.
