2016-10-24sparc64: Setup a scheduling domain for highest level cache.Atish Patra
Individual scheduler domain should consist different hierarchy consisting of cores sharing similar property. Currently, no scheduler domain is defined separately for the cores that shares the last level cache. As a result, the scheduler fails to take advantage of cache locality while migrating tasks during load balancing. Here are the cpu masks currently present for sparc that are/can be used in scheduler domain construction. cpu_core_map : set based on the cores that shares l1 cache. core_core_sib_map : is set based on the socket id. The prior SPARC notion of socket was defined as highest level of shared cache. However, the MD record on T7 platforms now describes the CPUs that share the physical socket and this is no longer tied to shared cache. That's why a separate cpu mask needs to be created that truly represent highest level of shared cache for all platforms.

2016-10-24mei: txe: don't clean an unprocessed interrupt cause.Alexander Usyskin
SEC registers are not accessible when the TXE device is in low power state, hence the SEC interrupt cannot be processed if device is not awake. In some rare cases entrance to low power state (aliveness off) and input ready bits can be signaled at the same time, resulting in communication stall as input ready won't be signaled again after waking up. To resolve this IPC_HHIER_SEC bit in HHISR_REG should not be cleaned if the interrupt is not processed.

2016-10-24spi: mark device nodes only in case of successful instantiationRalf Ramsauer
Instantiated SPI device nodes are marked with OF_POPULATE. This was introduced in bd6c164. On unloading, loaded device nodes will of course be unmarked. The problem are nodes that fail during initialisation: If a node fails, it won't be unloaded and hence not be unmarked. If a SPI driver module is unloaded and reloaded, it will skip nodes that failed before. Skip device nodes that are already populated and mark them only in case of success. Note that the same issue exists for I2C.

2016-10-24ARCv2: IOC: use @ioc_enable not @ioc_exist where intendedVineet Gupta
if user disables IOC from debugger at startup (by clearing @ioc_enable), @ioc_exists is cleared too. This means boot prints don't capture the fact that IOC was present but disabled which could be misleading. So invert how we use @ioc_enable and @ioc_exists and make it more canonical. @ioc_exists represent whether hardware is present or not and stays same whether enabled or not. @ioc_enable is still user driven, but will be auto-disabled if IOC hardware is not present, i.e. if @ioc_exist=0. This is opposite to what we were doing before, but much clearer. This means @ioc_enable is now the "exported" toggle in rest of code such as dma mapping API.

2016-10-24ARC: syscall for userspace cmpxchg assistVineet Gupta
Older ARC700 cores (ARC750 specifically) lack instructions to implement atomic r-w-w. This is problematic for userspace libraries such as NPTL which need atomic primitives. So enable them by providing kernel assist. This is costly but really the only sane soluton (othern than tight spinning using the otherwise availiable atomic exchange EX instruciton). Good thing is there are only a few of these cores running Linux out in the wild. This only works on UP systems.

In btrfs_truncate_inode_items()->btrfs_async_run_delayed_refs(), we swap the arg2 and arg3 wrongly, fix this. This bug just impacts asynchronous delayed refs handle when we truncate inodes.

This is because some glue layers expect musb_platform_enable/disable to be called with spinlock held, and 2430 glue layer has USB PHY on the I2C bus using a mutex. We could fix the glue layers to take the spinlock, but we still have a problem of musb_plaform_enable/disable being called in an unbalanced manner. So that would still lead into USB PHY enable/disable related problems for omap2430 glue layer. While it makes sense to only enable USB PHY when needed from PM point of view, in this case we just can't do it yet without breaking things. So let's just revert phy_enable/disable related changes instead and reconsider this after we have fixed musb_platform_enable/disable to be balanced.

2016-10-24ACPI/PCI: pci_link: penalize SCI correctlySinan Kaya
Ondrej reported that IRQs stopped working in v4.7 on several platforms. A typical scenario, from Ondrej's VT82C694X/694X, is: ACPI: Using PIC for interrupt routing ACPI: PCI Interrupt Link [LNKA] (IRQs 1 3 4 5 6 7 10 *11 12 14 15) ACPI: No IRQ available for PCI Interrupt Link [LNKA] 8139too 0000:00:0f.0: PCI INT A: no GSI We're using PIC routing, so acpi_irq_balance == 0, and LNKA is already active at IRQ 11. In that case, acpi_pci_link_allocate() only tries to use the active IRQ (IRQ 11) which also happens to be the SCI. We should penalize the SCI by PIRQ_PENALTY_PCI_USING, but irq_get_trigger_type(11) returns something other than IRQ_TYPE_LEVEL_LOW, so we penalize it by PIRQ_PENALTY_ISA_ALWAYS instead, which makes acpi_pci_link_allocate() assume the IRQ isn't available and give up. Add acpi_penalize_sci_irq() so platforms can tell us the SCI IRQ, trigger, and polarity directly and we don't have to depend on irq_get_trigger_type().

2016-10-24Documentation/unicode.txt: convert it to ReST markupMauro Carvalho Chehab
Probably, unicode is something that we might remove from the docs, as all modern systems support it. Yet, this chapter is fun, as it mentions support for the Klington fictional charset ;) On the other hand, I bet all other OS user manuals explicit mention unicode support. So, convert it to ReST and include it at the user's book. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
