The NFSv4 spec is ambiguous about whether or not it is permissible to reuse open owner names, so play it safe. This patch adds a timestamp to the state_owner structure, and combines that with the IDA based uniquifier. Fixes a regression whereby the Linux server returns NFS4ERR_BAD_SEQID.

2012-04-20VM: add "vm_mmap()" helper functionLinus Torvalds1-17/+6
This continues the theme started with vm_brk() and vm_munmap(): vm_mmap() does the same thing as do_mmap(), but additionally does the required VM locking. This uninlines (and rewrites it to be clearer) do_mmap(), which sadly duplicates it in mm/mmap.c and mm/nommu.c. But that way we don't have to export our internal do_mmap_pgoff() function. Some day we hopefully don't have to export do_mmap() either, if all modular users can become the simpler vm_mmap() instead. We're actually very close to that already, with the notable exception of the (broken) use in i810, and a couple of stragglers in binfmt_elf. Signed-off-by: Linus Torvalds <[email protected]>

2012-04-20VM: add "vm_brk()" helper functionLinus Torvalds1-1/+2

2012-04-20lib: add support for stmp-style devicesWolfram Sang1-0/+20
MX23/28 use IP cores which follow a register layout I have first seen on STMP3xxx SoCs. In this layout, every register actually has four u32: 1.) to store a value directly 2.) a SET register where every 1-bit sets the corresponding bit, others are unaffected 3.) same with a CLR register 4.) same with a TOG (toggle) register Also, the 2 MSBs in register 0 are always the same and can be used to reset the IP core. All this is strictly speaking not mach-specific (but IP core specific) and, thus, doesn't need to be in mach-mxs/include. At least mx6 also uses IP cores following this stmp-style. So: Introduce a stmp-style device, put the code and defines for that in a public place (lib/), and let drivers for stmp-style devices select that code. To avoid regressions and ease reviewing, the actual code is simply copied from mach-mxs. It definately wants updates, but those need a seperate patch series. Voila, mach dependency gone, reusable code introduced. Note that I didn't remove the duplicated code from mach-mxs yet, first the drivers have to be converted.

One switch device (e.g., MUIC(MAX8997, MAX77686, ...), and some 30-pin devices) may have multiple cables attached. For example, one 30-pin port may inhabit a USB cable, an HDMI cable, and a mic. Thus, one switch device requires multiple state bits each representing a type of cable. For such purpose, we use the 32bit state variable; thus, up to 32 different type of cables may be defined for a switch device. The list of possible cables is defined by the array of cable names in the switch_dev struct given to the class.

2012-04-20blkcg: mass rename of blkcg APITejun Heo1-2/+2
During the recent blkcg cleanup, most of blkcg API has changed to such extent that mass renaming wouldn't cause any noticeable pain. Take the chance and cleanup the naming. * Rename blkio_cgroup to blkcg. * Drop blkio / blkiocg prefixes and consistently use blkcg. * Rename blkio_group to blkcg_gq, which is consistent with io_cq but keep the blkg prefix / variable name. * Rename policy method type and field names to signify they're dealing with policy data. * Rename blkio_policy_type to blkcg_policy.

2012-04-20blkcg: implement per-queue policy activationTejun Heo1-0/+1
All blkcg policies were assumed to be enabled on all request_queues. Due to various implementation obstacles, during the recent blkcg core updates, this was temporarily implemented as shooting down all !root blkgs on elevator switch and policy [de]registration combined with half-broken in-place root blkg updates. In addition to being buggy and racy, this meant losing all blkcg configurations across those events. Now that blkcg is cleaned up enough, this patch replaces the temporary implementation with proper per-queue policy activation. Each blkcg policy should call the new blkcg_[de]activate_policy() to enable and disable the policy on a specific queue. blkcg_activate_policy() allocates and installs policy data for the policy for all existing blkgs. blkcg_deactivate_policy() does the reverse. If a policy is not enabled for a given queue, blkg printing / config functions skip the respective blkg for the queue. blkcg_activate_policy() also takes care of root blkg creation, and cfq_init_queue() and blk_throtl_init() are updated accordingly. This replaces blkcg_bypass_{start|end}() and update_root_blkg_pd() unnecessary. Dropped. v2: cfq_init_queue() was returning uninitialized @ret on root_group alloc failure if !CONFIG_CFQ_GROUP_IOSCHED. Fixed.

2012-04-20blkcg: add request_queue->root_blkgTejun Heo1-0/+2
With per-queue policy activation, root blkg creation will be moved to blkcg core. Add q->root_blkg in preparation. For blk-throtl, this replaces throtl_data->root_tg; however, cfq needs to keep cfqd->root_group for !CONFIG_CFQ_GROUP_IOSCHED. This is to prepare for per-queue policy activation and doesn't cause any functional difference.

2012-04-18tegra, serial8250: add ->handle_break() uart_port opDan Williams3-0/+23
The "KT" serial port has another use case for a "received break" quirk, so before adding another special case to the 8250 core take this opportunity to push such quirks out of the core and into a uart_port op. Stephen says: "If the callback function is to no longer live in 8250.c itself, arch/arm/mach-tegra/devices.c isn't logically a good place to put it, and that file will be going away once we get rid of all the board files and move solely to device tree." ...so since 8250_pci.c houses all the quirks for pci serial devices this quirk is similarly housed in of_serial.c. Once the open firmware conversion completes the infrastructure details (include/linux/of_serial.h, and the export) can all be removed to make this self contained to of_serial.c.

2012-04-18bcma: scan for extra address spaceHauke Mehrtens1-0/+1
Some cores like the USB core have two address spaces. In the USB host controller one address space is used for the OHCI and the other for the EHCI controller interface. The USB controller is the only core I found with two address spaces. This code is based on the AI scan function ai_scan() in shared/aiutils.c in the Broadcom SDK.

2012-04-18regulator: tps65090: Use generic regmap enable/disable operationsAxel Lin1-0/+13
This patch converts tps65090 regulator driver to use generic regmap enable/disable operations. Also move struct tps65090 to include/linux/mfd/tps65090.h because the regulator driver needs to access the rmap field of struct tps65090.

2012-04-18usb: ehci-tegra: Add vbus_gpio to platform dataStephen Warren1-0/+1
Add a vbus_gpio field to platform data. This mirrors the device tree property nvidia,vbus-gpio. This makes the VBUS GPIO handling identical between booting with board files and device tree; the driver always does it. This removes the need for board files to request and initialize the GPIO early during their boot process, perhaps even before the GPIO driver is ready to process the request.

These functions allow the driver core to automatically clean up any allocations made by drivers, thus leading to simplified drivers. Signed-off-by: Stephen Warren <[email protected]> Signed-off-by: Linus Walleij <[email protected]>

2012-04-18dt: add property iteration helpersStephen Warren1-0/+35
This patch adds macros of_property_for_each_u32() and of_property_for_each_string(), which iterate over an array of values within a device-tree property. Usage is for example: struct property *prop; const __be32 *p; u32 u; of_property_for_each_u32(np, "propname", prop, p, u) printk("U32 value: %x\n", u); struct property *prop; const char *s; of_property_for_each_string(np, "propname", prop, s) printk("String value: %s\n", s); Based on work by Rob Herring <[email protected]> Cc: Grant Likely <[email protected]> Signed-off-by: Stephen Warren <[email protected]> Acked-by: Rob Herring <[email protected]> Signed-off-by: Linus Walleij <[email protected]>
2012-04-18pinctrl: replace list_*() with get_*_count()Viresh Kumar2-8/+5
Most of the SoC drivers implement list_groups() and list_functions() routines for pinctrl and pinmux. These routines continue returning zero until the selector argument is greater than total count of available groups or functions. This patch replaces these list_*() routines with get_*_count() routines, which returns the number of available selection for SoC driver. pinctrl layer will use this value to check the range it can choose. This patch fixes all user drivers for this change. There are other routines in user drivers, which have checks to check validity of selector passed to them. It is also no more required and hence removed. Documentation updated as well.
