2012-05-23mfd: ab8500-core should depend on MFD_DB8500_PRCMULee Jones

2012-05-23i915: add dmabuf/prime buffer sharing support.Daniel Vetter
This adds handle->fd and fd->handle support to i915, this is to allow for offloading of rendering in one direction and outputs in the other. v2 from Daniel Vetter: - fixup conflicts with the prepare/finish gtt prep work. - implement ppgtt binding support. Note that we have squat i-g-t testcoverage for any of the lifetime and access rules dma_buf/prime support brings along. And there are quite a few intricate situations here. Also note that the integration with the existing code is a bit hackish, especially around get_gtt_pages and put_gtt_pages. It imo would be easier with the prep code from Chris Wilson's unbound series, but that is for 3.6. Also note that I didn't bother to put the new prepare/finish gtt hooks to good use by moving the dma_buf_map/unmap_attachment calls in there (like we've originally planned for). Last but not least this patch is only compile-tested, but I've changed very little compared to Dave Airlie's version. So there's a decent chance v2 on drm-next works as well as v1 on 3.4-rc. v3: Right when I've hit sent I've noticed that I've screwed up one obj->sg_list (for dmar support) and obj->sg_table (for prime support) disdinction. We should be able to merge these 2 paths, but that's material for another patch. v4: fix the error reporting bugs pointed out by ickle. v5: fix another error, and stop non-gtt mmaps on shared objects stop pread/pwrite on imported objects, add fake kmap Signed-off-by: Dave Airlie <airlied@redhat.com> Signed-Off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2012-05-23[SCSI] fcoe, bnx2fc, libfcoe: SW FCoE and bnx2fc use FCoE SyfsRobert Love
This patch has the SW FCoE driver and the bnx2fc driver make use of the new fcoe_sysfs API added earlier in this patch series. After this patch a fcoe_ctlr_device is allocated with private data in this order. +------------------+ +------------------+ | fcoe_ctlr_device | | fcoe_ctlr_device | +------------------+ +------------------+ | fcoe_ctlr | | fcoe_ctlr | +------------------+ +------------------+ | fcoe_interface | | bnx2fc_interface | +------------------+ +------------------+ libfcoe also takes part in this new model since it discovers and manages fcoe_fcf instances. The memory allocation is different for FCFs. I didn't want to impact libfcoe's fcoe_fcf processing, so this patch creates fcoe_fcf_device instances for each discovered fcoe_fcf. The two are paired using a (void * priv) member of the fcoe_ctlr_device. This allows libfcoe to continue maintaining its list of fcoe_fcf instances and simply attaches and detaches them from existing or new fcoe_fcf_device instances.

2012-05-23[SCSI] libfcoe: Add fcoe_sysfsRobert Love
This patch adds a 'fcoe bus' infrastructure to the kernel that is driven by changes to libfcoe which allow LLDs to present FIP (FCoE Initialization Protocol) discovered entities and their attributes to user space via sysfs. This patch adds the following APIs- fcoe_ctlr_device_add fcoe_ctlr_device_delete fcoe_fcf_device_add fcoe_fcf_device_delete They allow the LLD to expose the FCoE ENode Controller and any discovered FCFs (Fibre Channel Forwarders, e.g. FCoE switches) to the user. Each of these new devices has their own bus_type so that they are grouped together for easy lookup from a user space application. Each new class has an attribute_group to expose attributes for any created instances. The attributes are- fcoe_ctlr_device * fcf_dev_loss_tmo * lesb_link_fail * lesb_vlink_fail * lesb_miss_fka * lesb_symb_err * lesb_err_block * lesb_fcs_error fcoe_fcf_device * fabric_name * switch_name * priority * selected * fc_map * vfid * mac * fka_peroid * fabric_state * dev_loss_tmo A device loss infrastructre similar to the FC Transport's is also added by this patch. It is nice to have so that a link flapping adapter doesn't continually advance the count used to identify the discovered FCF. FCFs will exist in a "Disconnected" state until either the timer expires or the FCF is rediscovered and becomes "Connected." This patch generates a few checkpatch.pl WARNINGS that I'm not sure what to do about. They're macros modeled around the FC Transport attribute building macros, which have the same 'feature' where the caller can ommit a cast in the argument list and no cast occurs in the code. I'm not sure how to keep the code condensed while keeping the macros. Any advice would be appreciated.

2012-05-23[SCSI] bnx2fc: Allocate fcoe_ctlr with bnx2fc_interface, not as a memberRobert Love
Currently the fcoe_ctlr associated with an interface is allocated as a member of struct bnx2fc_interface. This causes problems when when later patches attempt to use the new fcoe_sysfs APIs which allow us to allocate the bnx2fc_interface as private data to a fcoe_ctlr_device instance. The problem is that libfcoe wants to be able use pointer math to find a fcoe_ctlr's fcoe_ctlr_device as well as finding a fcoe_ctlr_device's assocated fcoe_ctlr. To do this we need to allocate the fcoe_ctlr_device, with private data for the LLD. The private data will contain the fcoe_ctlr and its private data will be the bnx2fc_interface. +-------------------+ | fcoe_ctlr_device | +-------------------+ | fcoe_ctlr | +-------------------+ | bnx2fc_interface | +-------------------+ This prep work will allow us to go from a fcoe_ctlr_device instance to its fcoe_ctlr as well as from a fcoe_ctlr to its fcoe_ctlr_device once the fcoe_sysfs API is in use (later patches in this series).

2012-05-23[SCSI] Fix dm-multipath starvation when scsi host is busyJun'ichi Nomura
block congestion control doesn't have any concept of fairness across multiple queues. This means that if SCSI reports the host as busy in the queue congestion control it can result in an unfair starvation situation in dm-mp if there are multiple multipath devices on the same host. For example: http://www.redhat.com/archives/dm-devel/2012-May/msg00123.html The fix for this is to report only the sdev busy state (and ignore the host busy state) in the block congestion control call back. The host is still congested, but the SCSI subsystem will sort out the congestion in a fair way because it knows the relation between the queues and the host.

We deleted a staging driver, which was nice, and finally dropped the obsolete usbfs code, which will make Al happy to never have to touch that again. There were some build errors in the tree that linux-next found a few days ago, but those were fixed by the most recent changes (all were due to us not building with CONFIG_PM disabled.)

2012-05-22[libata] Add " 2GB ATA Flash Disk"/"ADMA428M" to DMA blacklistPrarit Bhargava
A user has several systems with a couple of models of flash disks with IDE connectors. These disks work fine in 2.6.18-ish kernels but corrupt data on new kernels. The difference appears to be with the default I/O method used by the IDE controller driver between the kernels. In the older kernels, the configuration is very conservative and the driver stays in PIO mode. With new kernels, the ata driver (pata_serverworks) attempts to use UDMA/66 which the drive claims to support. This mode, however, does not appear to work in DMA mode. The drive does work correctly and no corruption is seen if the kernel parameter "libata.force=5:pio0,6:pio0" is used to force the driver to use PIO instead of DMA mode. Blacklist these drives. Unfortunately the model name of the drive is very generic, " 2GB ATA Flash Disk", but the revision is specific, "ADMA428M".

2012-05-22iommu/core: pass a user-provided token to fault handlersOhad Ben-Cohen
Sometimes a single IOMMU user may have to deal with several different IOMMU devices (e.g. remoteproc). When an IOMMU fault happens, such users have to regain their context in order to deal with the fault. Users can't use the private fields of neither the iommu_domain nor the IOMMU device, because those are already used by the IOMMU core and low level driver (respectively). This patch just simply allows users to pass a private token (most notably their own context pointer) to iommu_set_fault_handler(), and then makes sure it is provided back to the users whenever an IOMMU fault happens. The patch also adopts remoteproc to the new fault handling interface, but the real functionality using this (recovery of remote processors) will only be added later in a subsequent patch set.

This patch adds support for tcm_qla2xxx fabric module for target-core using the new qla_target.c LLD logic. This includes support for explict NodeACLs via configfs using tcm_qla2xxx_setup_nacl_from_rport() from libfc struct fc_host->rports, and demo-mode support for virtual LUN=0 access. This patch also adds support for using tcm_qla2xxx_lport->lport_fcport_map and ->lport_loopid_map of btree_head32 to track struct se_node_acl pointers for individual 24-bit Port ID and 16-bit Loop ID values w/ qla_target_template ->find_sess_by_s_id() and ->find_sess_by_loop_id() used in a number of locations into the primary I/O dispatch logic in qla_target.c LLD code. The main piece for FC Nexus setup is in tcm_qla2xxx_check_initiator_node_acl(), which calls tcm_qla2xxx_set_sess_by_[s_id,loop_id]() to setup our lport->lport_fcport_map and lport_loopid_map pointers respectively, and register the new nexus with TCM via __transport_register_session().

2012-05-22[SCSI] qla2xxx: Add LLD target-mode infrastructure for >= 24xx seriesNicholas Bellinger
Add LLD target mode for >= 24xx series HW. This code was originally based on external qla2x00t module based on 8.02.01-k4, and has been refactored to push the bulk of code into mainline qla2xxx.ko LLD -> qla_target.c. The implementation uses internal workqueues for I/O context submission into tcm_qla2xxx code, and includes the struct qla_tgt_func_tmpl API for external interaction to allow qla2xxx LDD to function without direct target-core dependencies: It also enables qla_target.c usage within existing qla2xxx LLD code. This includes: *) Addition of target mode specific members to existing data structures in qla_def.h and struct qla_hw_data->tgt_ops using qla_target.h:struct qla_tgt_func_tmpl *) Addition of struct qla_tgt_func_tmpl and direct calls into qla_target.c logic w/ qlt_* prefixed functions. *) Addition of qla_iocb.c:qla2x00_req_pkt() for ring processing, and qla2x00_issue_marker() for handling request/response queue processing for target mode operation *) Addition of various qla_tgt_mode_enabled() logic checks in qla24xx_nvram_config(), qla2x00_initialize_adapter(), qla2x00_rff_id(), qla2x00_abort_isp(), qla24xx_modify_vp_config(), and qla2x00_vp_abort_isp(). By default the new qlini_mode module parameter is setting initiator-mode to 'enabled' in order for 'modprobe qla2xxx' to continue to function as expected in initiator only mode. Enabling target-mode operation will currently require a: modprobe qla2xxx qlini_mode="disabled" in order to explictly disabled initiator mode and allow target-mode to be enabled via tcm_qla2xxx configfs fabric callers.
