Pull final round of SCSI updates from James Bottomley: "Sorry for the delay in this patch which was mostly caused by getting the merger of the mpt2/mpt3sas driver, which was seen as an essential item of maintenance work to do before the drivers diverge too much. Unfortunately, this caused a compile failure (detected by linux-next), which then had to be fixed up and incubated. In addition to the mpt2/3sas rework, there are updates from pm80xx, lpfc, bnx2fc, hpsa, ipr, aacraid, megaraid_sas, storvsc and ufs plus an assortment of changes including some year 2038 issues, a fix for a remove before detach issue in some drivers and a couple of other minor issues" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (141 commits) mpt3sas: fix inline markers on non inline function declarations sd: Clear PS bit before Mode Select. ibmvscsi: set max_lun to 32 ibmvscsi: display default value for max_id, max_lun and max_channel. mptfusion: don't allow negative bytes in kbuf_alloc_2_sgl() scsi: pmcraid: replace struct timeval with ktime_get_real_seconds() mvumi: 64bit value for seconds_since1970 be2iscsi: Fix bogus WARN_ON length check scsi_scan: don't dump trace when scsi_prep_async_scan() is called twice mpt3sas: Bump mpt3sas driver version to 09.102.00.00 mpt3sas: Single driver module which supports both SAS 2.0 & SAS 3.0 HBAs mpt2sas, mpt3sas: Update the driver versions mpt3sas: setpci reset kernel oops fix mpt3sas: Added OEM Gen2 PnP ID branding names mpt3sas: Refcount fw_events and fix unsafe list usage mpt3sas: Refcount sas_device objects and fix unsafe list usage mpt3sas: sysfs attribute to report Backup Rail Monitor Status mpt3sas: Ported WarpDrive product SSS6200 support mpt3sas: fix for driver fails EEH, recovery from injected pci bus error mpt3sas: Manage MSI-X vectors according to HBA device type ...

git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending Pull SCSI target updates from Nicholas Bellinger: "This series contains HCH's changes to absorb configfs attribute ->show() + ->store() function pointer usage from it's original tree-wide consumers, into common configfs code. It includes usb-gadget, target w/ drivers, netconsole and ocfs2 changes to realize the improved simplicity, that now renders the original include/target/configfs_macros.h CPP magic for fabric drivers and others, unnecessary and obsolete. And with common code in place, new configfs attributes can be added easier than ever before. Note, there are further improvements in-flight from other folks for v4.5 code in configfs land, plus number of target fixes for post -rc1 code" In the meantime, a new user of the now-removed old configfs API came in through the char/misc tree in commit 7bd1d4093c2f ("stm class: Introduce an abstraction for System Trace Module devices"). This merge resolution comes from Alexander Shishkin, who updated his stm class tracing abstraction to account for the removal of the old show_attribute and store_attribute methods in commit 517982229f78 ("configfs: remove old API") from this pull. As Alexander says about that patch: "There's no need to keep an extra wrapper structure per item and the awkward show_attribute/store_attribute item ops are no longer needed. This patch converts policy code to the new api, all the while making the code quite a bit smaller and easier on the eyes. Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com>" That patch was folded into the merge so that the tree should be fully bisectable. * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (23 commits) configfs: remove old API ocfs2/cluster: use per-attribute show and store methods ocfs2/cluster: move locking into attribute store methods netconsole: use per-attribute show and store methods target: use per-attribute show and store methods spear13xx_pcie_gadget: use per-attribute show and store methods dlm: use per-attribute show and store methods usb-gadget/f_serial: use per-attribute show and store methods usb-gadget/f_phonet: use per-attribute show and store methods usb-gadget/f_obex: use per-attribute show and store methods usb-gadget/f_uac2: use per-attribute show and store methods usb-gadget/f_uac1: use per-attribute show and store methods usb-gadget/f_mass_storage: use per-attribute show and store methods usb-gadget/f_sourcesink: use per-attribute show and store methods usb-gadget/f_printer: use per-attribute show and store methods usb-gadget/f_midi: use per-attribute show and store methods usb-gadget/f_loopback: use per-attribute show and store methods usb-gadget/ether: use per-attribute show and store methods usb-gadget/f_acm: use per-attribute show and store methods usb-gadget/f_hid: use per-attribute show and store methods ...

2015-11-13drm: Don't oops in drm_calc_timestamping_constants() if drm_vblank_init() ↵Ville Syrjälä1-1/+9
wasn't called Seems the crtc helpers call drm_calc_timestamping_constants() unconditionally even if the driver didn't initialize vblank support by calling drm_vblank_init(). That used to be OK since the constants were stored under drm_crtc. However I broke this with commit eba1f35dfe14 ("drm: Move timestamping constants into drm_vblank_crtc") when I moved the constants to live inside the drm_vblank_crtc struct instead. If drm_vblank_init() isn't called, we don't allocate these structures, and so drm_calc_timestamping_constants() will oops. Fix it by adding a check into drm_calc_timestamping_constants() to see if vblank support was initialized at all. And to keep in line with other such checks, also toss in a check and warn for the case where vblank support was initialized, but the wrong number of crtcs was specified.

2015-11-12sd: Clear PS bit before Mode Select.Gabriel Krisman Bertazi1-0/+1
According to SPC-4, in a Mode Select, the PS bit in Mode Pages is reserved and must be set to 0 by the driver. In the sd implementation, function cache_type_store does a Mode Sense, which might set the PS bit on the read buffer, followed by a Mode Select, which receives the same buffer, without explicitly clearing the PS bit. So, in cases where target supports saving the Mode Page to a non-volatile location, we end up doing a Mode Select with the PS bit set, which could cause an illegal request error if the target is checking this. This was observed on a new firmware change, which was subsequently reverted, but this changes sd.c to be more compliant with SPC-4. This patch clears the PS bit in the buffer returned by Mode Select, right before it is used in the Mode Select command.

2015-11-12scsi: pmcraid: replace struct timeval with ktime_get_real_seconds()Alison Schofield1-3/+2
Replace the use of struct timeval and do_gettimeofday() with 64 bit ktime_get_real_seconds. Prevents 32-bit type overflow in year 2038 on 32-bit systems. Driver was using the seconds portion of struct timeval (.tv_secs) to pass a millseconds timestamp to the firmware. This change maintains that same behavior using ktime_get_real_seconds. The structure used to pass the timestamp to firmware is 48 bits and works fine as long as the top 16 bits are zero and they will be zero for a long time..ie. thousands of years. Alternative Change: Add sub second granularity to timestamp As noted above, the driver only used the seconds portion of timeval, ignores the microseconds portion, and by multiplying by 1000 effectively does a <<10 and always writes zero into timestamp[0]. The alternative change would pass all the bits to the firmware: struct timespec64 ts; ktime_get_real_ts64(&ts); timestamp = ts.tv_sec * MSEC_PER_SEC + ts.tv_nsec / NSEC_PER_MSEC; Signed-off-by: Alison Schofield <amsfield22@gmail.com> Reviewed-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Martin K.

It is however, written to, using 'struct timeval' which has a 32-bit seconds field and whose value will overflow in year 2038.

2015-11-12mpt3sas: Single driver module which supports both SAS 2.0 & SAS 3.0 HBAsSreekanth Reddy14-826/+566
Modified the mpt3sas driver to have a single driver module which supports both SAS 2.0 & SAS 3.0 HBA devices. * Added SAS 2.0 HBA device IDs to the mpt3sas_pci_table pci table. * Created two separate SCSI host templates for SAS2 and SAS3 HBAs so that, during the driver load time driver can use corresponding host template(based the pci device ID) while registering a scsi host adapter instance for that pci device. * Registered two IOCTL devices, mpt2ctl is for SAS2 HBAs & mpt3ctl for SAS3 HBAs. Also updated the code to make sure that mpt2ctl device processes only those ioctl cmds issued for the SAS2 HBAs and mpt3ctl device processes only those ioctl cmds issued for the SAS3 HBAs. * Added separate indexing for SAS2 and SAS3 HBAs. * Replaced compile time check 'MPT2SAS_SCSI' to run time check 'hba_mpi_version_belonged' whereever needed. * Aliased this merged driver to mpt2sas using MODULE_ALIAS. * Moved global varaible 'driver_name' to per adapter instance variable. * Created two raid function template and used corresponding raid function templates based on the run time check 'hba_mpi_version_belonged'. * Moved mpt2sas_warpdrive.c file from mpt2sas to mpt3sas folder and renamed it as mpt3sas_warpdrive.c. * Also renamed the functions in mpt3sas_warpdrive.c file to follow current driver function name convention. * Updated the Makefile to build mpt3sas_warpdrive.o file for these WarpDrive-specific functions. * Also in function mpt3sas_setup_direct_io(), used sector_div() API instead of division operator (which gives compilation errors on 32 bit machines). * Removed mpt2sas files, mpt2sas directory & mpt3sas_module.c file. * Added module parameter 'hbas_to_enumerate' which permits using this merged driver as a legacy mpt2sas driver or as a legacy mpt3sas driver. Here are the available options for this module parameter: 0 - Merged driver which enumerates both SAS 2.0 & SAS 3.0 HBAs 1 - Acts as legacy mpt2sas driver, which enumerates only SAS 2.0 HBAs 2 - Acts as legacy mpt3sas driver, which enumerates only SAS 3.0 HBAs * Removed mpt2sas entries from SCSI's Kconfig and Makefile files.

This patch is ported from commit 008549f6e8a1 ("mpt2sas: Refcount fw_events and fix unsafe list usage"). These changes are also required for mpt3sas.

2015-11-12mpt3sas: Refcount sas_device objects and fix unsafe list usageSreekanth Reddy3-157/+365
sas_device objects can be referenced concurrently throughout the driver. We need a way to make sure threads can't delete them out from under each other. This patch adds the refcount and refactors the code to use it. Additionally, we cannot iterate over the sas_device_list without holding the lock or we risk corrupting random memory if items are added or deleted as we iterate. This patch refactors _scsih_probe_sas() to use the sas_device_list in a safe way. This patch is ported from the following mpt2sas driver commit d224fe0d6097 ("mpt2sas: Refcount sas_device objects and fix unsafe list usage").

2015-11-12mpt3sas: sysfs attribute to report Backup Rail Monitor StatusSreekanth Reddy3-0/+116
A new sysfs shost attribute called "BMR_status" is implemented to report Backup Rail Monitor status. This attribute is located in: /sys/class/scsi_host/host#/BMR_status When reading this adapter attribute, the driver will output the state of GPIO[24]. It returns "0" if BMR is healthy and "1" for failure. If it returns an empty string then it means that there was an error while obtaining the BMR status. Check dmesg for what error has occurred. This sysfs shost attribute is mainly for WarpDrive controllers. This commit is a port of 6c265660c262 ("mpt2sas: Provide sysfs attribute to report Backup Rail Monitor Status").

2015-11-12mpt2sas, mpt3sas: Remove SCSI_MPTXSAS_LOGGING entry from KconfigSreekanth Reddy7-83/+10
Currently there is a logging level option provided for each of our drivers in the kernel configuration utility. Users can enable this option to get more verbose information. By default it is enabled. Only when this option is enabled will the functions which display the required information get compiled in. As we are merging the both drivers we can no longer provide this configuration option. Remove the SCSI_MPTXSAS_LOGGING entry from Kconfig and unconditionally enable logging (by removing the #ifdef CONFIG_SCSI_MPT3SAS_LOGGING preprocessor check conditions) so that all functions which are defined to display more verbose information get compiled in.
