2015-05-01powerpc/eeh: Delay probing EEH device during hotplugGavin Shan
Commit 1c509148b ("powerpc/eeh: Do probe on pci_dn") probes EEH devices in early stage, which is reasonable to pSeries platform. However, it's wrong for PowerNV platform because the PE# isn't determined until the resources (IO and MMIO) are assigned to PE in hotplug case. So we have to delay probing EEH devices for PowerNV platform until the PE# is assigned.

2015-05-01powerpc/eeh: Fix race condition in pcibios_set_pcie_reset_state()Gavin Shan
When asserting reset in pcibios_set_pcie_reset_state(), the PE is enforced to (hardware) frozen state in order to drop unexpected PCI transactions (except PCI config read/write) automatically by hardware during reset, which would cause recursive EEH error. However, the (software) frozen state EEH_PE_ISOLATED is missed. When users get 0xFF from PCI config or MMIO read, EEH_PE_ISOLATED is set in PE state retrival backend. Unfortunately, nobody (the reset handler or the EEH recovery functinality in host) will clear EEH_PE_ISOLATED when the PE has been passed through to guest. The patch sets and clears EEH_PE_ISOLATED properly during reset in function pcibios_set_pcie_reset_state() to fix the issue.

2015-05-01powerpc/pseries: Correct cpu affinity for dlpar added cpusNathan Fontenot
The incorrect ordering of operations during cpu dlpar add results in invalid affinity for the cpu being added. The ibm,associativity property in the device tree is populated with all zeroes for the added cpu which results in invalid affinity mappings and all cpus appear to belong to node 0. This occurs because rtas configure-connector is called prior to making the rtas set-indicator calls. Phyp does not assign affinity information for a cpu until the rtas set-indicator calls are made to set the isolation and allocation state. Correct the order of operations to make the rtas set-indicator calls (done in dlpar_acquire_drc) before calling rtas configure-connector.

Commit 7bc5a2bad0b8 'ACPI: Support _OSI("Darwin") correctly' caused the MacBook firmware to expose the SBS, resulting in intermittent hangs of several minutes on boot, and failure to detect or report the battery. Fix this by adding a 5 us delay to the start of each SMBUS transaction. This timing is the result of experimentation - hangs were observed with 3 us but never with 5 us.

2015-04-30ARM: pxa: pxa_cplds: add lubbock and mainstone IORobert Jarzmik
Historically, this support was in arch/arm/mach-pxa/lubbock.c and arch/arm/mach-pxa/mainstone.c. When gpio-pxa was moved to drivers/pxa, it became a driver, and its initialization and probing happened at postcore initcall. The lubbock code used to install the chained lubbock interrupt handler at init_irq() time. The consequence of the gpio-pxa change is that the installed chained irq handler lubbock_irq_handler() was overwritten in pxa_gpio_probe(_dt)(), removing : - the handler - the falling edge detection setting of GPIO0, which revealed the interrupt request from the lubbock IO board. As a fix, move the gpio0 chained handler setup to a place where we have the guarantee that pxa_gpio_probe() was called before, so that lubbock handler becomes the true IRQ chained handler of GPIO0, demuxing the lubbock IO board interrupts. This patch moves all that handling to a mfd driver. It's only purpose for the time being is the interrupt handling, but in the future it should encompass all the motherboard CPLDs handling : - leds - switches - hexleds The same logic applies to mainstone board.

2015-04-30net/mlx4_en: Schedule napi when RX buffers allocation failsIdo Shamay
When system is out of memory, refilling of RX buffers fails while the driver continue to pass the received packets to the kernel stack. At some point, when all RX buffers deplete, driver may fall into a sleep, and not recover when memory for new RX buffers is once again availible. This is because hardware does not have valid descriptors, so no interrupt will be generated for the driver to return to work in napi context. Fix it by schedule the napi poll function from stats_task delayed workqueue, as long as the allocations fail.

2015-04-30x86/PCI/ACPI: Make all resources except [io 0xcf8-0xcff] available on PCI busJiang Liu
An IO port or MMIO resource assigned to a PCI host bridge may be consumed by the host bridge itself or available to its child bus/devices. The ACPI specification defines a bit (Producer/Consumer) to tell whether the resource is consumed by the host bridge itself, but firmware hasn't used that bit consistently, so we can't rely on it. Before commit 593669c2ac0f ("x86/PCI/ACPI: Use common ACPI resource interfaces to simplify implementation"), arch/x86/pci/acpi.c ignored all IO port resources defined by acpi_resource_io and acpi_resource_fixed_io to filter out IO ports consumed by the host bridge itself. Commit 593669c2ac0f ("x86/PCI/ACPI: Use common ACPI resource interfaces to simplify implementation") started accepting all IO port and MMIO resources, which caused a regression that IO port resources consumed by the host bridge itself became available to its child devices. Then commit 63f1789ec716 ("x86/PCI/ACPI: Ignore resources consumed by host bridge itself") ignored resources consumed by the host bridge itself by checking the IORESOURCE_WINDOW flag, which accidently removed MMIO resources defined by acpi_resource_memory24, acpi_resource_memory32 and acpi_resource_fixed_memory32. On x86 and IA64 platforms, all IO port and MMIO resources are assumed to be available to child bus/devices except one special case: IO port [0xCF8-0xCFF] is consumed by the host bridge itself to access PCI configuration space. So explicitly filter out PCI CFG IO ports[0xCF8-0xCFF]. This solution will also ease the way to consolidate ACPI PCI host bridge common code from x86, ia64 and ARM64.

2015-04-30[media] saa717x: fix multi-byte read codeMauro Carvalho Chehab
As reported by smatch: drivers/media/i2c/saa717x.c:155 saa717x_read() warn: mask and shift to zero drivers/media/i2c/saa717x.c:155 saa717x_read() warn: mask and shift to zero This is done right at saa717x_write(), but the read function is broken. Thankfully, there's just one place at saa717x driver that uses multibyte read (for status report, via printk). Yet, let's fix it. From saa717x_write(), it is clear that the bytes are in little endian: mm1[4] = (value >> 16) & 0xff; mm1[3] = (value >> 8) & 0xff; mm1[2] = value & 0xff; So, the same order should be valid for read too.
