Pull MTD fixes from Brian Norris: "Two MTD fixes for 4.1: - readtest: the signal-handling code was clobbering the error codes we should be handling/reporting in this test, rendering it useless. Noticed by Coverity. - the common SPI NOR flash DT binding (merged for 4.1-rc1) is being revised, so let's change that before 4.1 is minted" * tag 'for-linus-20150516' of git://git.infradead.org/linux-mtd: Documentation: dt: mtd: replace "nor-jedec" binding with "jedec, spi-nor" mtd: readtest: don't clobber error reports

Documentation: dt: mtd: replace "nor-jedec" binding with "jedec, spi-nor"

2015-05-15T20:04:00Z

In commit 8ff16cf77ce3 ("Documentation: devicetree: m25p80: add "nor-jedec" binding"), we added a generic "nor-jedec" binding to catch all mostly-compatible SPI NOR flash which can be detected via the READ ID opcode (0x9F). This was discussed and reviewed at the time, however objections have come up since then as part of this discussion: http://lkml.kernel.org/g/20150511224646.GJ32500@ld-irv-0074 It seems the parties involved agree that "jedec,spi-nor" does a better job of capturing the fact that this is SPI-specific, not just any NOR flash. This binding was only merged for v4.1-rc1, so it's still OK to change the naming. At the same time, let's move the documentation to a better name. Next up: stop referring to code (drivers/mtd/devices/m25p80.c) from the documentation.

UBI: block: Add missing cache flushes

2015-05-06T20:52:22Z

Block drivers are responsible for calling flush_dcache_page() on each BIO request. This operation keeps the I$ coherent with the D$ on architectures that don't have hardware coherency support. Without this flush, random crashes are seen when executing user programs from an ext4 filesystem backed by a ubiblock device. This patch is based on the change implemented in commit 2d4dc890b5c8 ("block: add helpers to run flush_dcache_page() against a bio and a request's pages").

Pull MTD updates from Brian Norris: "Common MTD: - Add Kconfig option for keeping both the 'master' and 'partition' MTDs registered as devices. This would really make a better default if we could do it over, as it allows a lot more flexibility in (1) determining the flash topology of the system from user-space and (2) adding temporary partitions at runtime (ioctl(BLKPG)). Unfortunately, this would possibly cause user-space breakage, as it will cause renumbering of the /dev/mtdX devices. We'll see if we can change this in the future, as there have already been a few people looking for this feature, and I know others have just been working around our current limitations instead of fixing them this way. - Along with the previous change, add some additional information to sysfs, so user-space can read the offset of each partition within its master device SPI NOR: - add new device tree compatible binding to represent the mostly-compatible class of SPI NOR flash which can be detected by their extended JEDEC ID bytes, cutting down the duplication of our ID tables - misc. new IDs Various other miscellaneous fixes and changes" * tag 'for-linus-20150422' of git://git.infradead.org/linux-mtd: (53 commits) mtd: spi-nor: Add support for Macronix mx25u6435f serial flash mtd: spi-nor: Add support for Winbond w25q64dw serial flash mtd: spi-nor: add support for the Winbond W25X05 flash mtd: spi-nor: support en25s64 device mtd: m25p80: bind to "nor-jedec" ID, for auto-detection Documentation: devicetree: m25p80: add "nor-jedec" binding mtd: Make MTD tests cancelable mtd: mtd_oobtest: Fix bitflip_limit usage in test case 3 mtd: docg3: remove invalid __exit annotations mtd: fsl_ifc_nand: use msecs_to_jiffies for time conversion mtd: atmel_nand: don't map the ROM table if no pmecc table offset in DT mtd: atmel_nand: add a definition for the oob reserved bytes mtd: part: Remove partition overlap checks mtd: part: Add sysfs variable for offset of partition mtd: part: Create the master device node when partitioned mtd: ts5500_flash: Fix typo in MODULE_DESCRIPTION in ts5500_flash.c mtd: denali: Disable sub-page writes in Denali NAND driver mtd: pxa3xx_nand: cleanup wait_for_completion handling mtd: nand: gpmi: Check for scan_bbt() error mtd: nand: gpmi: fixup return type of wait_for_completion_timeout ...
