2017-05-14scsi: mac_scsi: Fix MAC_SCSI=m option when SCSI=mFinn Thain
commit 2559a1ef688f933835912c731bed2254146a9b04 upstream. The mac_scsi driver still gets disabled when SCSI=m. This should have been fixed back when I enabled the tristate but I didn't see the bug.

2016-04-11g_ncr5380: Remove CONFIG_SCSI_GENERIC_NCR53C400Finn Thain
This change brings a number of improvements: fewer macros, better test coverage, simpler code and sane Kconfig options. The downside is a small chance of incompatibility (which seems unavoidable). CONFIG_SCSI_GENERIC_NCR53C400 exists to enable or inhibit pseudo DMA transfers when the driver is used with 53C400-compatible cards. Thanks to Ondrej Zary's patches, PDMA now works which means it can be enabled unconditionally. Due to bad design, CONFIG_SCSI_GENERIC_NCR53C400 ties together unrelated functionality as it sets both PSEUDO_DMA and BIOSPARAM macros. This patch effectively enables PSEUDO_DMA and disables BIOSPARAM. The defconfigs and the Kconfig default leave CONFIG_SCSI_GENERIC_NCR53C400 undefined. Red Hat 9 and CentOS 2.1 were the same. This leaves both PSEUDO_DMA and BIOSPARAM disabled. The effect of this patch should be better performance from enabling PSEUDO_DMA. On the other hand, Debian 4 and SLES 10 had CONFIG_SCSI_GENERIC_NCR53C400 enabled, so both PSEUDO_DMA and BIOSPARAM were enabled. This patch might affect configurations like this by disabling BIOSPARAM. My best guess is that this could be a problem only in the vanishingly rare case that 1) the CHS values stored in the boot device partition table are wrong and 2) a 5380 card is in use (because PDMA on 53C400 used to be broken).

2016-04-11scsi: reduce CONFIG_SCSI_CONSTANTS=y impact by 8kRasmus Villemoes
On 64 bit, struct error_info has 6 bytes of padding, which amounts to over 4k of wasted space in the additional[] array. We could easily get rid of that by instead using separate arrays for the codes and the pointers. However, we can do even better than that and save an additional 6 bytes per entry: In the table, just store the sizeof() the corresponding string literal. The cumulative sum of these is then the appropriate offset into additional_text, which is built from the concatenation (with '\0's inbetween) of the strings. $ scripts/bloat-o-meter /tmp/vmlinux vmlinux add/remove: 0/0 grow/shrink: 1/1 up/down: 24/-8488 (-8464) function old new delta scsi_extd_sense_format 136 160 +24 additional 11312 2824 -8488 The Kconfig help text used to say that CONFIG_SCSI_CONSTANTS=y costs around 75 KB, but that was a little exaggerated.

2016-01-07atari_NCR5380: Remove RESET_BOOT, CONFIG_ATARI_SCSI_TOSHIBA_DELAY and ↵Finn Thain
CONFIG_ATARI_SCSI_RESET_BOOT The atari_NCR5380.c core driver now takes care of bus reset upon driver initialization if required (same as NCR5380.c). Move the Toshiba CD-ROM support into the core driver, enabled with a host flag, so that all NCR5380 drivers can make use of it. Drop the RESET_BOOT macros and the ATARI_SCSI_RESET_BOOT and ATARI_SCSI_TOSHIBA_DELAY Kconfig symbols, which are now redundant. Remove the atari_scsi_reset_boot(), mac_scsi_reset_boot() and sun3_scsi_reset_boot() routines. None of this duplicated code is needed now that all drivers can use NCR5380_maybe_reset_bus(). This brings atari_scsi, mac_scsi and sun3_scsi into line with all of the other NCR5380 drivers. The bus reset may raise an interrupt. That would be new behaviour for atari_scsi only when CONFIG_ATARI_SCSI_RESET_BOOT=n. The ST DMA interrupt is not assigned to atari_scsi at this stage, so CONFIG_ATARI_SCSI_RESET_BOOT=y may well be problematic already. Regardless, do_reset() now raises and clears the interrupt within local_irq_save/restore which should avoid problems.

2015-12-19ses: fix discovery of SATA devices in SAS enclosuresJames Bottomley
The current discovery routines use the VPD 0x83 inquiry page to find the device SAS address and match it to the end point in the enclosure. This doesn't work for SATA devices because expanders (or hosts) simply make up an endpoint address for STP and thus the address returned by the VPD page never matches. Instead of doing this, for SAS attached devices, match by the direct endpoint address instead. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

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.

Pull core block layer changes from Jens Axboe: "This is the core block IO pull request for 3.18. Apart from the new and improved flush machinery for blk-mq, this is all mostly bug fixes and cleanups. - blk-mq timeout updates and fixes from Christoph. - Removal of REQ_END, also from Christoph. We pass it through the ->queue_rq() hook for blk-mq instead, freeing up one of the request bits. The space was overly tight on 32-bit, so Martin also killed REQ_KERNEL since it's no longer used. - blk integrity updates and fixes from Martin and Gu Zheng. - Update to the flush machinery for blk-mq from Ming Lei. Now we have a per hardware context flush request, which both cleans up the code should scale better for flush intensive workloads on blk-mq. - Improve the error printing, from Rob Elliott. - Backing device improvements and cleanups from Tejun. - Fixup of a misplaced rq_complete() tracepoint from Hannes. - Make blk_get_request() return error pointers, fixing up issues where we NULL deref when a device goes bad or missing. From Joe Lawrence. - Prep work for drastically reducing the memory consumption of dm devices from Junichi Nomura. This allows creating clone bio sets without preallocating a lot of memory. - Fix a blk-mq hang on certain combinations of queue depths and hardware queues from me. - Limit memory consumption for blk-mq devices for crash dump scenarios and drivers that use crazy high depths (certain SCSI shared tag setups).
