* mfd: arizona: Correct type of gpio_defaultsCharles Keepax2015-03-30
| | | | | | | | | | | | | gpio_defaults needs to be specified as an unsigned int rather than an int, because the intention of the DT binding is that all out of range values for a 16-bit register will cause the defaults to be used, however, if gpio_defaults is an int then values that are larger than INT_MAX will become negative numbers and be written out directly to the hardware. As no where in the code replies on gpio_defaults being an int, the simplest fix is to just change it to unsigned.

* mfd: rk808: Disable the under voltage detectChris Zhong2015-03-12
| | | | | | | | | | | Rk808 has a under voltage detect function, when the voltage of buck is under 85% the target voltage, the buck output will reset. But if the power load is too heavy, this function maybe err, when current over 4.2A, although the voltage is normal, but RK808 mistakenly think it is under 85%, and reset the buck.

| | | | | | | | | | | | | | | In one shot mode, sequencer automatically disables all enabled steps at the end of each cycle. (both ADC steps and TSC steps) Hence these steps need not be saved in reg_se_cache for clearing these steps at a later stage. Also, when ADC wakes up Sequencer should not be busy executing any of the config steps except for the charge step. Previously charge step was 1 ADC clock cycle and hence it was ignored. TSC steps are always disabled at the end of each conversion cycle, hence there is no need to explicitly disable TSC steps by writing 0 to REG_SE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split DCACHE_FILE_TYPE into DCACHE_REGULAR_TYPE (dentries representing regular files) and DCACHE_SPECIAL_TYPE (representing blockdev, chardev, FIFO and socket files). d_is_reg() and d_is_special() are added to detect these subtypes and d_is_file() is left as the union of the two. This allows a number of places that use S_ISREG(dentry->d_inode->i_mode) to use d_is_reg(dentry) instead.

| * VFS: Introduce inode-getting helpers for layered/unioned fs environmentsDavid Howells2015-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce some function for getting the inode (and also the dentry) in an environment where layered/unioned filesystems are in operation. The problem is that we have places where we need *both* the union dentry and the lower source or workspace inode or dentry available, but we can only have a handle on one of them. Therefore we need to derive the handle to the other from that. The idea is to introduce an extra field in struct dentry that allows the union dentry to refer to and pin the lower dentry.

| * | MIPS,prctl: add PR_[GS]ET_FP_MODE prctl options for MIPSPaul Burton2015-02-12

For example, userland code may be built to target the O32 FPXX ABI. Such code may be linked with other FPXX code, or code built for either one of the more restrictive FP32 or FP64. When linking with more restrictive code, the overall requirement of the process becomes that of the more restrictive code. The kernel has no way to know in advance which mode the process will need to be executed in, and indeed it may need to change during execution. The dynamic loader is the only code which will know the overall required mode, and so it needs to have a means to instruct the kernel to switch the FP mode of the process. This patch introduces 2 new options to the prctl syscall which provide such a capability. The FP mode of the process is represented as a simple bitmask combining a number of mode bits mirroring those present in the hardware. Userland can either retrieve the current FP mode of the process: mode = prctl(PR_GET_FP_MODE); or modify the current FP mode of the process: err = prctl(PR_SET_FP_MODE, new_mode); Signed-off-by: Paul Burton <paul.burton@imgtec.com> Cc: Matthew Fortune <matthew.fortune@imgtec.com> Cc: Markos Chandras <markos.chandras@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/8899/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

However commit e9de688dac65 ("irqchip: mips-gic: Support local interrupts") changed the condition from cpu_has_veic to gic_present. This fails on cores such as P5600 which have a GIC but the local interrupts aren't routable by the GIC, causing c0_compare_int_usable() to consider the interrupt unusable so r4k_clockevent_init() fails. The previous behaviour, added in commit 98b67c37db33 ("MIPS: Add EIC support for GIC."), wasn't really correct either as far as I can tell, since P5600 apparently supports EIC mode too, and in any case the use of Cause.TI with r2 should have been sufficient anyway since commit 010c108d7af7 ("MIPS: PowerTV: Fix support for timer interrupts with > 64 external IRQs"). Therefore drop the call into the gic driver altogether, and add a comment in c0_compare_int_pending() to clarify that Cause.TI does get checked since MIPS r2.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver has to end unreturned commands at some point even if the controller has not provided a completion. The driver tried to be safe by deleting IO queues prior to ending all unreturned commands. That should cause the controller to internally abort inflight commands, but IO queue deletion request does not have to be successful, so all bets are off. We still have to make progress, so to be extra safe, this patch doesn't clear a queue to release the dma mapping for a command until after the pci device has been disabled. This patch removes the special handling during device initialization so controller recovery can be done all the time. This is possible since initialization is not inlined with pci probe anymore.

| | * | | | | NVMe: Register management handle under nvme classKeith Busch2015-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This creates a new class type for nvme devices to register their management character devices with. This is so we do not rely on miscdev to provide enough minors for as many nvme devices some people plan to use. The previous limit was approximately 60 NVMe controllers, depending on the platform and kernel. Now the limit is 1M, which ought to be enough for anybody. Since we have a new device class, it makes sense to attach the block devices under this as well, so part of this patch moves the management handle initialization prior to the namespaces discovery.

| | * | | | | NVMe: Update SCSI Inquiry VPD 83h translationKeith Busch2015-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original translation created collisions on Inquiry VPD 83 for many existing devices. Newer specifications provide other ways to translate based on the device's version can be used to create unique identifiers. Version 1.1 provides an EUI64 field that uniquely identifies each namespace, and 1.2 added the longer NGUID field for the same reason. Both follow the IEEE EUI format and readily translate to the SCSI device identification EUI designator type 2h. For devices implementing either, the translation will use this type, defaulting to the EUI64 8-byte type if implemented then NGUID's 16 byte version if not. If neither are provided, the 1.0 translation is used, and is updated to use the SCSI String format to guarantee a unique identifier. Knowing when to use the new fields depends on the nvme controller's revision. The NVME_VS macro was not decoding this correctly, so that is fixed in this patch and moved to a more appropriate place. Since the Identify Namespace structure required an update for the NGUID field, this patch adds the remaining new 1.2 fields to the structure. Signed-off-by: Keith Busch <keith.busch@intel.com>
| | * | | | | NVMe: Metadata format supportKeith Busch2015-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds support for NVMe metadata formats and exposes block devices for all namespaces regardless of their format. Namespace formats that are unusable will have disk capacity set to 0, but a handle to the block device is created to simplify device management. A namespace is not usable when the format requires host interleave block and metadata in single buffer, has no provisioned storage, or has better data but failed to register with blk integrity. The namespace has to be scanned in two phases to support separate metadata formats. The first establishes the sector size and capacity prior to invoking add_disk. If metadata is required, the capacity will be temporarilly set to 0 until it can be revalidated and registered with the integrity extenstions after add_disk completes. The driver relies on the integrity extensions to provide the metadata buffer. NVMe requires this be a single physically contiguous region, so only one integrity segment is allowed per command. If the metadata is used for T10 PI, the driver provides mappings to save and restore the reftag physical block translation. The driver provides no-op functions for generate and verify if metadata is not used for protection information. This way the setup is always provided by the block layer. If a request does not supply a required metadata buffer, the command is failed with bad address. This could only happen if a user manually disables verify/generate on such a disk. The only exception to where this is okay is if the controller is capable of stripping/generating the metadata, which is possible on some types of formats. The metadata scatter gather list now occupies the spot in the nvme_iod that used to be used to link retryable IOD's, but we don't do that anymore, so the field was unused.

It changes core_scsi3_update_and_write_aptpl() to use vzalloc'ed memory instead of kzalloc, and increases the default hardcoded length to 256k. It also adds logic in core_scsi3_update_and_write_aptpl() to double the original length upon core_scsi3_update_aptpl_buf() failure, and retries until the vzalloc'ed buffer is large enough to accommodate the outgoing APTPL metadata.
