2014-11-20mtd: nand: provide detailed description for raw read/write page methodsBoris BREZILLON
read_page_raw and write_page_raw method description is not clear enough. It clearly specifies that ECC correction should not be involved but does not talk about specific layout (by layout I mean where in-band and out-of-band data are stored on the NAND media) used by NAND/ECC controllers. Those specific layouts might impact MTD users and thus should be hidden (as already done in the standard NAND_ECC_HW_SYNDROME implementation). Clearly state this constraint in the nand_ecc_ctrl struct documentation. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>

2014-11-05mtd: atmel_nand: make PMECC lookup table and offset property optionalJosh Wu
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.

2014-10-29mtd: cfi_cmdset_0001.c: fix resume for LH28F640BF chipsDmitry Eremin-Solenikov
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.

2014-10-22mtd: orion_nand: fix error code path in probeMichael Opdenacker
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.

Pull audit updates from Eric Paris: "So this change across a whole bunch of arches really solves one basic problem. We want to audit when seccomp is killing a process. seccomp hooks in before the audit syscall entry code. audit_syscall_entry took as an argument the arch of the given syscall. Since the arch is part of what makes a syscall number meaningful it's an important part of the record, but it isn't available when seccomp shoots the syscall... For most arch's we have a better way to get the arch (syscall_get_arch) So the solution was two fold: Implement syscall_get_arch() everywhere there is audit which didn't have it. Use syscall_get_arch() in the seccomp audit code. Having syscall_get_arch() everywhere meant it was a useless flag on the stack and we could get rid of it for the typical syscall entry. The other changes inside the audit system aren't grand, fixed some records that had invalid spaces. Better locking around the task comm field. Removing some dead functions and structs.
