2015-12-13tty: Remove dead tty_write_flush() declaration and macroPeter Hurley
tty_write_flush() has no definition and the TTY_WRITE_FLUSH() macro is never invoked; remove. Signed-off-by: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2015-12-13tty: Remove __func__ from tty_debug() macroPeter Hurley
Now that tty_debug() macro uses pr_debug(), the function name can be printed when using dynamic debug; printing the function name within the format string is redundant. Remove the __func__ parameter and print specifier from the format string. Add context to messages for when the function name is not printed by dynamic debug, or when dynamic debug is not enabled.

2015-12-13tty: Define tty_*() printk macrosPeter Hurley
Since not all ttys are devices (eg., SysV ptys), dev_*() printk macros cannot be used. Define tty_*() printk macros that output in similar format to dev_*() macros (ie., <driver> <tty>: .....). Transform the most-trivial printk( LEVEL ...) usage to tty_*() usage. NB: The function name has been eliminated from messages with unique context, or prefixed to the format when given.

2015-12-13serial: support 16-bit register interface for consoleMasahiro Yamada
Currently, 8-bit (MMIO) and 32-bit (MMIO32) register interfaces are supported for the 8250 console, but the 16-bit (MMIO16) is not. The 8250 UART device on my board is connected to a 16-bit bus and my main motivation is to use earlycon with it.

Jan Stancek reported that I wrecked things for him by fixing things for Vladimir :/ His report was due to an UNINTERRUPTIBLE wait getting -EINTR, which should not be possible, however my previous patch made this possible by unconditionally checking signal_pending(). We cannot use current->state as was done previously, because the instruction after the store to that variable it can be changed. We must instead pass the initial state along and use that.

2015-12-13watchdog: core: add reboot notifier supportDamien Riegel
Many watchdog drivers register a reboot notifier in order to stop the watchdog on system reboot. Thus we can factorize this code in the watchdog core. For that purpose, a new notifier block is added in watchdog_device for internal use only, as well as a new watchdog_stop_on_reboot helper function. If this helper is called, watchdog core registers the related notifier block and will stop the watchdog when SYS_HALT or SYS_DOWN is received. Since this operation can be critical on some platforms, abort the device registration if the reboot notifier registration fails.

2015-12-12spi: add spi_message_init_no_memset to avoid zeroing the spi_messageMartin Sperl
In the spi_loopback_test driver there is the need to initialize a spi_message that is filled with values from a static structure. Applying spi_message_init to such a prefilled structure results in all the settings getting reset to zero, which is not what we want. Copying each field of spi_message separately instead always includes the risk that some new fields have not been implemented in the copying code. So here we introduce a version of spi_message_init called spi_message_init_no_memset that does not fill the structure with zero first, but only initializes the relevant list_heads.

2015-12-12kernel: remove stop_machine() Kconfig dependencyChris Wilson
Currently the full stop_machine() routine is only enabled on SMP if module unloading is enabled, or if the CPUs are hotpluggable. This leads to configurations where stop_machine() is broken as it will then only run the callback on the local CPU with irqs disabled, and not stop the other CPUs or run the callback on them. For example, this breaks MTRR setup on x86 in certain configs since ea8596bb2d8d379 ("kprobes/x86: Remove unused text_poke_smp() and text_poke_smp_batch() functions") as the MTRR is only established on the boot CPU. This patch removes the Kconfig option for STOP_MACHINE and uses the SMP and HOTPLUG_CPU config options to compile the correct stop_machine() for the architecture, removing the false dependency on MODULE_UNLOAD in the process.

Flow steering initialization is based on static tree which illustrates the flow steering tree when the driver is loaded. The initialization considers the max supported flow table level of the device, a minimum of 2 kernel flow tables(vlan and mac) are required to have kernel flow table functionality. The tree structures when the driver is loaded: root_namespace(receive nic) | priority-0 (kernel priority) | namespace(kernel namespace) | priority-0 (flow tables priority) In the following patches, When the EN driver will use the flow steering API, it create two flow tables and their flow groups under priority-0(flow tables priority).

2015-12-11netcp: try to reduce type confusion in descriptorsArnd Bergmann
The netcp driver produces tons of warnings when CONFIG_LPAE is enabled on ARM: drivers/net/ethernet/ti/netcp_core.c: In function 'netcp_tx_map_skb': drivers/net/ethernet/ti/netcp_core.c:1084:13: warning: passing argument 1 of 'set_words' from incompatible pointer type [-Wincompatible-pointer-types] This is the result of trying to pass a pointer to a dma_addr_t to a function that expects a u32 pointer to copy that into a DMA descriptor. Looking at that code in more detail to fix the warnings, I see multiple related problems: * The conversion functions are not endian-safe, as the DMA descriptors are almost certainly fixed-endian, but the CPU is not. * On 64-bit machines, passing a pointer through a u32 variable is a bug, accessing an indirect pointer as a u32 pointer even more so. * The handling of epib and psdata mixes native-endian and device-endian data. In this patch, I try to sort out the types for most accesses here, adding le32_to_cpu/cpu_to_le32 where appropriate, and passing pointers through two 32-bit words in the descriptor padding, to make it plausible that the driver does the right thing if compiled for big-endian or 64-bit systems.

This adds an abstraction that allows ULPs to simply pass a completion object and completion callback with each submitted WR and let the RDMA core handle the nitty gritty details of how to handle completion interrupts and poll the CQ. In detail there is a new ib_cqe structure which just contains the completion callback, and which can be used to get at the containing object using container_of. It is pointed to by the WR and WC as an alternative to the wr_id field, similar to how many ULPs already use the field to store a pointer using casts. A driver using the new completion callbacks allocates it's CQs using the new ib_create_cq API, which in addition to the number of CQEs and the completion vectors also takes a mode on how we poll for CQEs. Three modes are available: direct for drivers that never take CQ interrupts and just poll for them, softirq to poll from softirq context using the to be renamed blk-iopoll infrastructure which takes care of rearming and budgeting, or a workqueue for consumer who want to be called from user context. Thanks a lot to Sagi Grimberg who helped reviewing the API, wrote the current version of the workqueue code because my two previous attempts sucked too much and converted the iSER initiator to the new API.

2015-12-11ses: fix additional element traversal bugJames Bottomley
KASAN found that our additional element processing scripts drop off the end of the VPD page into unallocated space. The reason is that not every element has additional information but our traversal routines think they do, leading to them expecting far more additional information than is present. Fix this by adding a gate to the traversal routine so that it only processes elements that are expected to have additional information (list is in SES-2 section 6.1.13.1: Additional Element Status diagnostic page overview) Reported-by: Pavel Tikhomirov <ptikhomirov@virtuozzo.com> Tested-by: Pavel Tikhomirov <ptikhomirov@virtuozzo.com> Cc: stable@vger.kernel.org Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

Add get_eld audio component for i915/HD-audio Currently, the HDMI/DP audio status and ELD are notified and obtained via the hardware-level communication over HD-audio unsolicited event and verbs although the graphics driver holds the exactly same information. As we already have a notification via audio component, this is another step forward; namely, the audio driver may fetch directly the audio status and ELD via the new component op.

2015-12-11EDAC: Rip out the edac_subsys reference countingBorislav Petkov
This was really dumb - reference counting for the main EDAC sysfs object. While we could've simply registered it as the first thing in the module init path and then hand it around to what needs it. Do that and rip out all the code around it, thus simplifying the whole handling significantly. Move the edac_subsys node back to edac_module.c. Signed-off-by: Borislav Petkov <bp@suse.de>
2015-12-11EDAC, mpc85xx: Make mpc85xx-pci-edac a platform deviceScott Wood
Originally the mpc85xx-pci-edac driver bound directly to the PCI controller node. Commit 905e75c46dba ("powerpc/fsl-pci: Unify pci/pcie initialization code") turned the PCI controller code into a platform device. Since we can't have two drivers binding to the same device, the EDAC code was changed to be called into as a library-style submodule. However, this doesn't work if the EDAC driver is built as a module. Commit 8d8fcba6d1ea ("EDAC: Rip out the edac_subsys reference counting") exposed another problem with this approach -- mpc85xx_pci_err_probe() was being called in the same early boot phase that the PCI controller is initialized, rather than in the device_initcall phase that the EDAC layer expects. This caused a crash on boot. To fix this, the PCI controller code now creates a child platform device specifically for EDAC, which the mpc85xx-pci-edac driver binds to.

Since commit 4baadb9e05c68962 ("ARM: shmobile: r8a7778: remove obsolete setup code"), Renesas R-Car SoCs are only supported in generic DT-only ARM multi-platform builds. The driver doesn't need to use platform data anymore, hence remove platform data configuration. Make gpio_rcar_priv.has_both_edge_trigger a boolean for consistency with gpio_rcar_info.has_both_edge_trigger. Move gpio_rcar_priv.irq_parent down while we're at it, to prevent gaps on 64-bit.
