43c518d Tony Luck 02 July 2015, 19:12:53 UTC [IA64] Drop debug test/printk that some special pages are marked reserved In commit 92923ca3aace "mm: meminit: only set page reserved in the memblock region" we dropped setting the reserved bits for all pages.

An input queue and a processing queue is split out from the monolithic fuse connection, each of those having their own spinlock. The end of the patchset adds the ability to clone a fuse connection. This means, that instead of having to read/write requests/answers on a single fuse device fd, the fuse daemon can have multiple distinct file descriptors open. Each of those can be used to receive requests and send answers, currently the only constraint is that a request must be answered on the same fd as it was read from. This can be extended further to allow binding a device clone to a specific CPU or NUMA node. Based on a patchset by Srinivas Eeda and Ashish Samant.

This series includes a few final fixups needed prior to the relocation of the modular init code from <init.h> to <module.h>. These are things that weren't easily categorized into any of the other previous series categories already requested for pull. That said, each fixup branch (including this one) is independent and there are no ordering constraints. Only the final code relocation (which is NOT in this pull) requires that all my cleanup branches be merged first" * tag 'module-misc-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: tile: add init.h to usb.c to avoid compile failure arm: fix implicit #include <linux/init.h> in entry asm. x86: replace __init_or_module with __init in non-modular vsmp_64.c 02 July 2015, 18:07:27 UTC
75462c8 Linus Torvalds 02 July 2015, 17:42:13 UTC Merge tag 'module-builtin_driver-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux Pull module_platform_driver replacement from Paul Gortmaker: "Replace module_platform_driver with builtin_platform driver in non modules. We see an increasing number of non-modular drivers using modular_driver() type register functions. There are several downsides to letting this continue unchecked: - The code can appear modular to a reader of the code, and they won't know if the code really is modular without checking the Makefile and Kconfig to see if compilation is governed by a bool or tristate. - Coders of drivers may be tempted to code up an __exit function that is never used, just in order to satisfy the required three args of the modular registration function. - Non-modular code ends up including the <module.h> which increases CPP overhead that they don't need. - It hinders us from performing better separation of the module init code and the generic init code. So here we introduce similar macros for builtin drivers. Then we convert builtin drivers (controlled by a bool Kconfig) by making the following type of mapping: module_platform_driver() ---> builtin_platform_driver() module_platform_driver_probe() ---> builtin_platform_driver_probe(). The set of drivers that are converted here are just the ones that showed up as relying on an implicit include of <module.h> during a pending header cleanup. So we convert them here vs adding an include of <module.h> to non-modular code to avoid compile fails. Additonal conversions can be done asynchronously at any time. Once again, an unused module_exit function that is removed here appears in the diffstat as an outlier wrt all the other changes" * tag 'module-builtin_driver-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: drivers/clk: convert sunxi/clk-mod0.c to use builtin_platform_driver drivers/power: Convert non-modular syscon-reboot to use builtin_platform_driver drivers/soc: Convert non-modular soc-realview to use builtin_platform_driver drivers/soc: Convert non-modular tegra/pmc to use builtin_platform_driver drivers/cpufreq: Convert non-modular s5pv210-cpufreq.c to use builtin_platform_driver drivers/cpuidle: Convert non-modular drivers to use builtin_platform_driver drivers/platform: Convert non-modular pdev_bus to use builtin_platform_driver platform_device: better support builtin boilerplate avoidance 02 July 2015, 17:42:13 UTC
9d90f03 Linus Torvalds 02 July 2015, 17:36:29 UTC Merge tag 'module_init-alternate_initcall-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux Pull module_init replacement part two from Paul Gortmaker: "Replace module_init with appropriate alternate initcall in non modules. This series converts non-modular code that is using the module_init() call to hook itself into the system to instead use one of our alternate priority initcalls. Unlike the previous series that used device_initcall and hence was a runtime no-op, these commits change to one of the alternate initcalls, because (a) we have them and (b) it seems like the right thing to do. For example, it would seem logical to use arch_initcall for arch specific setup code and fs_initcall for filesystem setup code. This does mean however, that changes in the init ordering will be taking place, and so there is a small risk that some kind of implicit init ordering issue may lie uncovered. But I think it is still better to give these ones sensible priorities than to just assign them all to device_initcall in order to exactly preserve the old ordering. Thad said, we have already made similar changes in core kernel code in commit c96d6660dc65 ("kernel: audit/fix non-modular users of module_init in core code") without any regressions reported, so this type of change isn't without precedent. It has also got the same local testing and linux-next coverage as all the other pull requests that I'm sending for this merge window have got. Once again, there is an unused module_exit function removal that shows up as an outlier upon casual inspection of the diffstat" * tag 'module_init-alternate_initcall-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: x86: perf_event_intel_pt.c: use arch_initcall to hook in enabling x86: perf_event_intel_bts.c: use arch_initcall to hook in enabling mm/page_owner.c: use late_initcall to hook in enabling lib/list_sort: use late_initcall to hook in self tests arm: use subsys_initcall in non-modular pl320 IPC code powerpc: don't use module_init for non-modular core hugetlb code powerpc: use subsys_initcall for Freescale Local Bus x86: don't use module_init for non-modular core bootflag code netfilter: don't use module_init/exit in core IPV4 code fs/notify: don't use module_init for non-modular inotify_user code mm: replace module_init usages with subsys_initcall in nommu.c 02 July 2015, 17:36:29 UTC

This series of commits converts non-modular code that is using the module_init() call to hook itself into the system to instead use device_initcall(). The conversion is a runtime no-op, since module_init actually becomes __initcall in the non-modular case, and that in turn gets mapped onto device_initcall. A couple files show a larger negative diffstat, representing ones that had a module_exit function that we remove here vs previously relying on the linker to dispose of it. We make this conversion now, so that we can relocate module_init from init.h into module.h in the future.

We removed the __cpuinit stuff in 3.11-rc1 with commit 22f0a2736774 ("init.h: remove __cpuinit sections from the kernel") but we left some no-op stubs as a courtesy to unmerged code. Here we get rid of the stubs as well, since (as can be seen in these changes) they are enabling use cases to sneak back in, primarily from older BSP code that has been living out of tree for some time prior to getting mainlined. So we get rid of these "new" users 1st and then get rid of the stubs. Obviously, getting rid of the stubs can't happen until all the users are gone, so I had to keep this together as a series, even though some of these commits since got picked up into maintainers trees as well. The nature of this change is such that it should have zero impact on the generated runtime.

347d7e4 Stevens, Nick 01 July 2015, 16:07:41 UTC hwmon: (mcp3021) Fix broken output scaling The mcp3021 scaling code is dividing the VDD (full-scale) value in millivolts by the A2D resolution to obtain the scaling factor. When VDD is 3300mV (the standard value) and the resolution is 12-bit (4096 divisions), the result is a scale factor of 3300/4096, which is always one. Effectively, the raw A2D reading is always being returned because no scaling is applied. This patch fixes the issue and simplifies the register-to-volts calculation, removing the unneeded "output_scale" struct member.

Note that because of dependencies and merge conflicts these are based on Rafael's pm-wakeirq and Greg's tty-next branches. * tag 'omap-for-v4.2/wakeirq-drivers-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (148 commits) serial: 8250_omap: Move wake-up interrupt to generic wakeirq serial: omap: Switch wake-up interrupt to generic wakeirq tty: move linux/gsmmux.h to uapi doc: dt: add documentation for nxp,lpc1850-uart serial: 8250: add LPC18xx/43xx UART driver serial: 8250_uniphier: add UniPhier serial driver serial: 8250_dw: support ACPI platforms with integrated DMA engine serial: of_serial: check the return value of clk_prepare_enable() serial: of_serial: use devm_clk_get() instead of clk_get() serial: earlycon: Add support for big-endian MMIO accesses serial: sirf: use hrtimer for data rx serial: sirf: correct the fifo empty_bit serial: sirf: fix system hung on console log output serial: 8250: remove return statements from void function sc16is7xx: use kworker for RS-485 configuration sc16is7xx: use kworker to update ier bits sc16is7xx: use kworker for md_proc sc16is7xx: move RTS delay to workqueue sc16is7xx: use kthread_worker for tx_work and irq sc16is7xx: use LSR_TEMT_BIT in .tx_empty() ... 01 July 2015, 19:25:13 UTC

Use the cpu_resume_arm() wrapper instead of cpu_resume() to property switch into the THUMB2 state when we wake up from idle. This fixes a problem reported by Kevin Hilman on next-20150601 where the ifc6410 fails to boot a THUMB2 kernel because the platform's firmware always enters the kernel in ARM mode from deep idle states.

8f7bb36 Miklos Szeredi 01 July 2015, 14:26:03 UTC fuse: allow interrupt queuing without fc->lock Interrupt is only queued after the request has been sent to userspace. This is either done in request_wait_answer() or fuse_dev_do_read() depending on which state the request is in at the time of the interrupt. If it's not yet sent, then queuing the interrupt is postponed until the request is read. Otherwise (the request has already been read and is waiting for an answer) the interrupt is queued immedidately. We want to call queue_interrupt() without fc->lock protection, in which case there can be a race between the two functions: - neither of them queue the interrupt (thinking the other one has already done it). - both of them queue the interrupt The first one is prevented by adding memory barriers, the second is prevented by checking (under fiq->waitq.lock) if the interrupt has already been queued.
