2014-11-05staging:iio:ade7758: Remove "raw" from channel nameiio-fixes-for-3.18bLars-Peter Clausen
"raw" is a property of a channel, but should not be part of the name of channel. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Cc: <stable@vger.kernel.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2014-11-05staging:iio:ade7758: Fix NULL pointer deref when enabling bufferLars-Peter Clausen
In older versions of the IIO framework it was possible to pass a completely different set of channels to iio_buffer_register() as the one that is assigned to the IIO device. Commit 959d2952d124 ("staging:iio: make iio_sw_buffer_preenable much more general.") introduced a restriction that requires that the set of channels that is passed to iio_buffer_register() is a subset of the channels assigned to the IIO device as the IIO core will use the list of channels that is assigned to the device to lookup a channel by scan index in iio_compute_scan_bytes(). If it can not find the channel the function will crash. This patch fixes the issue by making sure that the same set of channels is assigned to the IIO device and passed to iio_buffer_register(). Note that we need to remove the IIO_CHAN_INFO_RAW and IIO_CHAN_INFO_SCALE info attributes from the channels since we don't actually want those to be registered.

2014-10-20staging: comedi: (regression) channel list must be set for COMEDI_CMD ioctlIan Abbott
`do_cmd_ioctl()`, the handler for the `COMEDI_CMD` ioctl can incorrectly call the Comedi subdevice's `do_cmd()` handler with a NULL channel list pointer. This is a regression as the `do_cmd()` handler has never been expected to deal with that, leading to a kernel OOPS when it tries to dereference it. A NULL channel list pointer is allowed for the `COMEDI_CMDTEST` ioctl, handled by `do_cmdtest_ioctl()` and the subdevice's `do_cmdtest()` handler, but not for the `COMEDI_CMD` ioctl and its handlers. Both `do_cmd_ioctl()` and `do_cmdtest_ioctl()` call `__comedi_get_user_chanlist()` to copy the channel list from user memory into dynamically allocated kernel memory and check it for consistency. That function currently returns 0 if the `user_chanlist` parameter (pointing to the channel list in user memory) is NULL. That's fine for `do_cmdtest_ioctl()`, but `do_cmd_ioctl()` incorrectly assumes the kernel copy of the channel list has been set-up correctly. Fix it by not allowing the `user_chanlist` parameter to be NULL in `__comedi_get_user_chanlist()`, and only calling it from `do_cmdtest_ioctl()` if the parameter is non-NULL. Thanks to Bernd Porr for reporting the bug via an initial patch sent privately.

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.

2014-10-18sparc64: Do not define thread fpregs save area as zero-length array.David S. Miller
This breaks the stack end corruption detection facility. What that facility does it write a magic value to "end_of_stack()" and checking to see if it gets overwritten. "end_of_stack()" is "task_thread_info(p) + 1", which for sparc64 is the beginning of the FPU register save area. So once the user uses the FPU, the magic value is overwritten and the debug checks trigger. Fix this by making the size explicit. Due to the size we use for the fpsaved[], gsr[], and xfsr[] arrays we are limited to 7 levels of FPU state saves. So each FPU register set is 256 bytes, allocate 256 * 7 for the fpregs area.

2014-10-18sparc64: Fix corrupted thread fault code.David S. Miller
Every path that ends up at do_sparc64_fault() must install a valid FAULT_CODE_* bitmask in the per-thread fault code byte. Two paths leading to the label winfix_trampoline (which expects the FAULT_CODE_* mask in register %g4) were not doing so: 1) For pre-hypervisor TLB protection violation traps, if we took the 'winfix_trampoline' path we wouldn't have %g4 initialized with the FAULT_CODE_* value yet. Resulting in using the TLB_TAG_ACCESS register address value instead. 2) In the TSB miss path, when we notice that we are going to use a hugepage mapping, but we haven't allocated the hugepage TSB yet, we still have to take the window fixup case into consideration and in that particular path we leave %g4 not setup properly. Errors on this sort were largely invisible previously, but after commit 4ccb9272892c33ef1c19a783cfa87103b30c2784 ("sparc64: sun4v TLB error power off events") we now have a fault_code mask bit (FAULT_CODE_BAD_RA) that triggers due to this bug. FAULT_CODE_BAD_RA triggers because this bit is set in TLB_TAG_ACCESS (see #1 above) and thus we get seemingly random bus errors triggered for user processes.

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. Summary for this pull: NAND - Cleanup for Denali driver - Atmel: add support for new page sizes - Atmel: fix up 'raw' mode support - Atmel: miscellaneous cleanups - New timing mode helpers for non-ONFI NAND - OMAP: allow driver to be (properly) built as a module - bcm47xx: RESET support and other cleanups SPI NOR - Miscellaneous cleanups, to prepare framework for wider use (some further work still pending) - Compile-time configuration to select 4K vs. 64K support for flash that support both (necessary for using UBIFS on some SPI NOR) A few scattered code quality fixes, detected by Coverity See the changesets for more" * tag 'for-linus-20141015' of git://git.infradead.org/linux-mtd: (59 commits) mtd: nand: omap: Correct CONFIG_MTD_NAND_OMAP_BCH help message mtd: nand: Force omap_elm to be built as a module if omap2_nand is a module mtd: move support for struct flash_platform_data into m25p80 mtd: spi-nor: add Kconfig option to disable 4K sectors mtd: nand: Move ELM driver and rename as omap_elm nand: omap2: Replace pr_err with dev_err nand: omap2: Remove horrible ifdefs to fix module probe mtd: nand: add Hynix's H27UCG8T2ATR-BC to nand_ids table mtd: nand: support ONFI timing mode retrieval for non-ONFI NANDs mtd: physmap_of: Add non-obsolete map_rom probe mtd: physmap_of: Fix ROM support via OF MAINTAINERS: add l2-mtd.git, 'next' tree for MTD mtd: denali: fix indents and other trivial things mtd: denali: remove unnecessary parentheses mtd: denali: remove another set-but-unused variable mtd: denali: fix include guard and license block of denali.h mtd: nand: don't break long print messages mtd: bcm47xxnflash: replace some magic numbers mtd: bcm47xxnflash: NAND_CMD_RESET support mtd: bcm47xxnflash: add cmd_ctrl handler ...

2014-10-18MAINTAINERS: Become the docs maintainerJonathan Corbet
It seems it's my turn to be the documentation maintainer for a bit. My plan is to work to ensure that docs patches don't fall through the cracks; I assume most changes will continue to flow through subsystem-specific trees.
