2015-04-02ARM: 8335/1: Documentation: DT bindings: Tegra AHB: document the legacy base addressPaul Walmsley1-2/+5
Documentation: DT bindings: Tegra AHB: require the legacy base address for existing chips Per Stephen Warren, note in the Tegra AHB DT binding documentation that we specifically deprecate any attempt to use the IP block's actual hardware base address, and advocate the use of the legacy "off-by-four" address in the 'regs' property, for Tegra chips with existing upstream Linux DT files that include a Tegra AHB node. This patch updates the documentation accordingly. Changing the existing kernel DT data isn't under consideration because Linux kernel DT data policy is to preserve compatibility between newer DT data files and older kernels. However, this additional step of changing the documentation should discourage others from sending kernel patches to try to change the legacy kernel DT data. Furthermore, for out-of-tree software (such as bootloaders or other operating systems) that may rely on Linux kernel DT binding documentation as an ABI (but not the Linux kernel DT data itself), such a change may allow future convergence with the Linux kernel DT data without additional code changes.

The eMMC on a tablet I've will stop working / communicating as soon as the kernel executes: mmc_switch(card, EXT_CSD_CMD_SET_NORMAL, EXT_CSD_HPI_MGMT, 1, card->ext_csd.generic_cmd6_time); There seems to be no way to reliable identify eMMC-s which have a broken hpi implementation, but at least for eMMC's which are soldered onto a board we can work around this by specifying that hpi is broken in devicetree.

2015-04-01IRQCHIP: Add new driver for BCM7038-style level 1 interrupt controllersKevin Cernekee1-0/+52
This is the main peripheral IRQ controller on the BCM7xxx MIPS chips; it has the following characteristics: - 64 to 160+ level IRQs - Atomic set/clear registers - Reasonably predictable register layout (N status words, then N mask status words, then N mask set words, then N mask clear words) - SMP affinity supported on most systems - Typically connected to MIPS IRQ 2,3,2,3 on CPUs 0,1,2,3 This driver registers one IRQ domain and one IRQ chip to cover all instances of the block. Up to 4 instances of the block may appear, as it supports 4-way IRQ affinity on BCM7435. The same block exists on the ARM BCM7xxx chips, but typically the ARM GIC is used instead. So this driver is primarily intended for MIPS STB chips.

2015-04-01IRQCHIP: bcm7120-l2: Split STB-specific logic into its own functionKevin Cernekee1-9/+3
The BCM7xxx instances of this block (listed in the register manual as simply "IRQ0") all have the following items in common: - brcm,int-map-mask: for routing different bits in the L2 to different parent IRQs - brcm,int-fwd-mask: for hardwiring certain IRQs to bypass the L2 and use dedicated L1 lines - one enable/status pair (32 bits only) Much of the driver code can be shared with BCM3380-style controllers, but in order to do this cleanly, let's split out the BCM7xxx-specific logic first.

2015-04-01x86/mm: Add support for the non-standard protected e820 typeChristoph Hellwig1-0/+6
Various recent BIOSes support NVDIMMs or ADR using a non-standard e820 memory type, and Intel supplied reference Linux code using this type to various vendors. Wire this e820 table type up to export platform devices for the pmem driver so that we can use it in Linux.

Chanwoo writes: Update extcon for v4.1 This patchset include two new extcon driver and fix minor issue of extcon driver. Detailed description for patchset: 1. new extcon-max77843.c and extcon-usb-gpio.c extcon driver - extcon-max77843.c driver support the MAXIM MAX77843 MUIC (Micor-USB Interface Controller) device which handles the various external connectors such as TA/USB /USB-HOST/JIG and so on. - extcon-usb-gpio.c driver support the USB and USB-HOST cable detection by using the GPIO pin which is connected to USB ID pin. This GPIO pin updates the USB cable states. 2. Rename the filename of extcon core driver and add missing locking mechanism - Rename the previous extcon-class driver.c as extcon.c because '-class' postfix is not necessary word. - extcon core driver (extcon.c) used the raw_notifier_chain. It must be protected by locking mechanism to avoid the list changing while extcon_update_state() is executed. 3. Fix minor issue of extcon drviers - Fix cable name by using the capital letter instead of small letter on extcon-max77693.c driver. - Clean-up code of extcon-arizona.c to detect headphone cable. - Fix the wrong return type and variable type on extcon-max77843.c. - Fix the checkpatch warning of all extcon drivers.

2015-04-01can: introduce new raw socket option to join the given CAN filtersOliver Hartkopp1-2/+18
The CAN_RAW socket can set multiple CAN identifier specific filters that lead to multiple filters in the af_can.c filter processing. These filters are indenpendent from each other which leads to logical OR'ed filters when applied. This socket option joines the given CAN filters in the way that only CAN frames are passed to user space that matched *all* given CAN filters. The semantic for the applied filters is therefore changed to a logical AND. This is useful especially when the filterset is a combination of filters where the CAN_INV_FILTER flag is set in order to notch single CAN IDs or CAN ID ranges from the incoming traffic. As the raw_rcv() function is executed from NET_RX softirq the introduced variables are implemented as per-CPU variables to avoid extensive locking at CAN frame reception time.

Spell out what this property means to userspace. If the property is set, all directional axes must be accelerometer axes, any other axes are left as-is. This allows an accelerometer device to e.g. have an ABS_WHEEL. It is not permitted to mix normal directional axes and accelerometer axes on the same device node.

2015-03-31KVM: s390: migrate vcpu interrupt stateJens Freimann1-0/+61
This patch adds support to migrate vcpu interrupts. Two new vcpu ioctls are added which get/set the complete status of pending interrupts in one go. The ioctls are marked as available with the new capability KVM_CAP_S390_IRQ_STATE. We can not use a ONEREG, as the number of pending local interrupts is not constant and depends on the number of CPUs. To retrieve the interrupt state we add an ioctl KVM_S390_GET_IRQ_STATE. Its input parameter is a pointer to a struct kvm_s390_irq_state which has a buffer and length. For all currently pending interrupts, we copy a struct kvm_s390_irq into the buffer and pass it to userspace. To store interrupt state into a buffer provided by userspace, we add an ioctl KVM_S390_SET_IRQ_STATE. It passes a struct kvm_s390_irq_state into the kernel and injects all interrupts contained in the buffer.
