2014-11-20mtd: mtd_oobtest: Show the verification error location and dataRoger Quadros1-7/+29
Add a function memcmpshow() that compares the 2 data buffers and shows the address:offset and data bytes on comparison failure. This function does not break at a comparison failure but runs the check for the whole data buffer. Use memcmpshow() instead of memcmp() for all the verification paths.

2014-11-06mtd: atmel_nand: make PMECC lookup table and offset property optionalJosh Wu2-4/+81
If there is no PMECC lookup table stored in ROM, or lookup table offset is not specified, PMECC driver should build it in DDR by itself. That make the PMECC driver work for some board which doesn't have PMECC lookup table in ROM. The PMECC use the BCH algorithm, so based on the build_gf_tables() function in lib/bch.c, we can build the Galois Field lookup table. For more information can refer to section 5.4 of PMECC controller application note: http://www.atmel.com/images/doc11127.pdf Signed-off-by: Josh Wu <josh.wu@atmel.com> Cc: devicetree@vger.kernel.org Signed-off-by: Brian Norris <computersforpeace@gmail.com>

After '#echo mem > /sys/power/state' some devices can not be properly resumed because apparently the MTD Partition Configuration Register has been reset to default thus the rootfs cannot be mounted cleanly on resume. An example of this can be found in the SA-1100 Developer's Manual at 9.5.3.3 where the second step of the Sleep Shutdown Sequence is described: "An internal reset is applied to the SA-1100. All units are reset...". As workaround we refresh the PCR value as done initially on chip setup. This behavior and the fix are confirmed by our tests done on 2 different Zaurus collie units with kernel 3.17.

nandsim can simulate NAND Flash which returns the ID bytes specified by first_id_byte, ..., fourth_id_byte module parameters. In order to simulate NAND flash which returns more than four ID bytes, this adds id_bytes module parameter which is specified by the array of byte like this: # modprobe nandsim id_bytes=0x98,0xdc,0x90,0x26,0x76,0x15,0x01,0x08 bch=1 This doesn't add fifth_id_byte, ..., seventh_id_byte module parameters, because they are redundant. But the existing first_id_byte, ..., fourth_id_byte module parameters are preserved and add "(obsolete)" to the description.

2014-10-22mtd: orion_nand: fix error code path in probeMichael Opdenacker1-28/+11
This replaces kzalloc() and ioremap() calls by devm_ functions in the probe() routine, which automatically release the corresponding resources when probe() fails or when the device is removed. This simplifies simplifies the error management code, and brings the below improvements or changes: A. Fixing a bug reported by "make coccicheck": If "board = devm_kzalloc()" fails, the probe() function jumps incorrectly to label "no_res" and therefore returns without running iounmap(). B. Requesting the memory region Using devm_ioremap_resource() makes the probe() function request the corresponding memory region before running ioremap(), as it is supposed to do. C. Standardizing the error codes: The use of devm_ioremap_resource() changes the return value: * -ENOMEM instead of -EIO in case of ioremap() failure, * -EINVAL instead of -ENODEV in case of platform_get_resource() failure.

m25p80's device ID table is now spi_nor_ids, defined in spi-nor. The MODULE_DEVICE_TABLE() macro doesn't work with extern definitions, but its use was also removed at the same time. Now if m25p80 is built as a module it doesn't get the necessary aliases to be loaded automatically. A clean solution to this will involve defining the list of device IDs in spi-nor.h and removing struct spi_device_id from the spi-nor API, but this is quite a large change. As a quick fix suitable for stable, copy the device IDs back into m25p80.

Summary: - fix DM's long-standing excessive use of memory by leveraging the new bioset_create_nobvec() interface when creating the DM's bioset - fix a few bugs in dm-bufio and dm-log-userspace - add DM core support for a DM multipath use-case that requires loading DM tables that contain devices that have failed (by allowing active and inactive DM tables to share dm_devs) - add discard support to the DM raid target; like MD raid456 the user must opt-in to raid456 discard support be specifying the devices_handle_discard_safely=Y module param" * tag 'dm-3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm log userspace: fix memory leak in dm_ulog_tfr_init failure path dm bufio: when done scanning return from __scan immediately dm bufio: update last_accessed when relinking a buffer dm raid: add discard support for RAID levels 4, 5 and 6 dm raid: add discard support for RAID levels 1 and 10 dm: allow active and inactive tables to share dm_devs dm mpath: stop queueing IO when no valid paths exist dm: use bioset_create_nobvec() dm: remove nr_iovecs parameter from alloc_tio()

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).

Pull MTD update from Brian Norris: "Sorry for delaying this a bit later than usual. There's one mild regression from 3.16 that was noticed during the 3.17 cycle, and I meant to send a fix for it along with this pull request. I'll probably try to queue it up for a later pull request once I've had a better look at it, hopefully by -rc2 at the latest.
