| * VFS: Split DCACHE_FILE_TYPE into regular and special typesDavid Howells2015-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Add a fallthrough flag for marking virtual dentriesDavid Howells2015-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | Add a DCACHE_FALLTHRU flag to indicate that, in a layered filesystem, this is a virtual dentry that covers another one in a lower layer that should be used instead. This may be recorded on medium if directory integration is stored there. The flag can be set with d_set_fallthru() and tested with d_is_fallthru().

| * 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: cevt-r4k: Drop GIC special caseJames Hogan2015-02-05

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 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.

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.

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>

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.

So remove support for legacy suspend/resume for I2C drivers. Since there aren't any special bus specific things to do during suspend/resume and since the PM core will automatically fallback directly to using the device's PM ops if no bus PM ops are specified there is no need to have any I2C bus PM ops.

On existing Tegra SoCs this was done by calling tegra_clocks_apply_init_table() from tegra_dt_init(). To make this also work on ARM64, we need to change this into an initcall. tegra_dt_init() is called from customize_machine which is an arch_initcall. Therefore this should also work on existing 32bit Tegra SoCs. Tested on Tegra20 (ventana), Tegra30 (beaverboard), Tegra124 (jetson TK1) and Tegra132.

Now that all platforms and drivers have been updated to remove static initializations of struct clk and struct clk_core objects and all references to clk-private.h have been removed we can move the definitions of these structures into drivers/clk/clk.c and delete the header. Additionally the ugly DEFINE_CLK macros have been removed. Those were used for static definitions of struct clk objects. That practice is no longer allowed. Finally __clk_init is staticized as it is no longer declared in any header. Reviewed-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Michael Turquette <mturquette@linaro.org>

This patch also introduces SoC specific init functions that shall be called from the low level init. The data format used in this file has two possible evolution paths; it can either be removed completely once no longer needed, or it will be possible to retain the format and modify the TI clock driver to be a loadable module at some point.

The struct clk that clk_get_parent() returns isn't owned by the caller, but by the clock implementation, so the former shouldn't call clk_put() on it. Because some boards in mach-omap2 still register clocks statically, their clock registration had to be updated to take into account that the clock information is stored in struct clk_core now.

It merely checks that the given parent clock can be a parent for the given clock. A situation where this is useful is to check that a particular setup is valid before switching to it. One specific use-case for this is atomic modesetting in the DRM framework where setting a mode is divided into a check phase where a given configuration is validated before applying changes to the hardware.

Drivers using these helpers could only unregister clocks but the memory would still leak. Add corresponding unregister functions which will release all resources.

However, we have a long standing TODO in the code to do something proactive to make that happen. To enable this, we add a request callback on the vfio bus driver struct, which is intended to signal the user through the vfio device interface to release the device. Instead of passively waiting for the device to become unused, we can now pester the user to give it up. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
