arm64: build vdso without libgcov
On a cross-toolchain without glibc support, libgcov may not be available, and attempting to build an arm64 kernel with GCOV enabled then results in a build error: /home/arnd/cross-gcc/lib/gcc/aarch64-linux/5.2.1/../../../../aarch64-linux/bin/ld: cannot find -lgcov We don't really want to link libgcov into the vdso anyway, so this patch just disables GCOV in the vdso directory, just as we do for most other architectures.

arm64: mark cpus_have_hwcap as __maybe_unused
cpus_have_hwcap() is defined as a 'static' function an only used in
one place that is inside of an #ifdef, so we get a warning when
the only user is disabled:
arch/arm64/kernel/cpufeature.c:699:13: warning: 'cpus_have_hwcap' defined but not used [-Wunused-function]
This marks the function as __maybe_unused, so the compiler knows that
it can drop the function definition without warning about it.

ARM: SoC defconfig updates for v4.4
Defconfig updates are kept separate from other branches mostly to avoid conflicts between the different categories (driver branch enabling something that has context conflict with SoC options, etc). A lot of this again is scattered across the various hardware platforms. multi_v7_defconfig, our "generic" config for most 32-bit platforms has been gone through by Marvell Berlin maintainers and added most options they need to run on their hardware. Broadcom NSP is also added there, and the new Atmel SAMA5D2 (added last release). Rockchip also has display and other devices supported in that config. In addition to that, the usual small churn of new options being added here and there. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJWQT5DAAoJEIwa5zzehBx3MvAP/0Unr4t9A63jQKc58ZtwMJ2a 1fxOyulNi4EjOzFbH0iXG+dYrIgAJpphrAhL1XvOgAohBhO+3H0orQJ+meLM4O04 DbZMBpkICqh/bgtojoPqxNxqMV3q+HGkhgcnohUqmlWYri9pdHhkpG3t7RUpUtP0 Acs67/Qud21ll4Cc0OPXXa9tKlZHBkYU/NDeQsY+YuiysF9VM2x0VnnoqLgPnDVS n8uZmAfYtAzdlI1BdAgJ1gSP76CMub1jEJMafc+44TYAt+74Ek43vmiGPXjRpITz c8g/l1hA6YdM9XZIGziqrCzZJf8XMa0/NZI8THqr1yUbSGkN4QVoDWHPKbxZUM7d rS1XfaJDCccz9traABGtylnJRhVlrY5zfiQHpRQKQXzyqzf09eC9nfsFU8ZRwgiq 11qEudGHUx0dWGbaPjfIvbifejA6Si0sYFkk85Ehhoeyu6ZGHXS2mGfAB2rNsX/Q 7s5o5nZhUzDe7MznITuhOxckWu2Mi9YD0bX6CDgV+7zhtLIyk0f+iXZ0thaqta1F JunSvh16q9O7yTT/zG23bXHCjGr/KWDhfVjE2kcij515b5rF9CsWjgdDH9KdIzvf F/u9/GHgK3hpXutbg0R+sdctoN7X5YdfxksqZekKCmTtWfUqknQF1csfE1TcUINl zVDvybfkRixRnPQmUwYV =KsDh -----END PGP SIGNATURE----- Merge tag 'armsoc-defconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC defconfig updates from Olof Johansson: "Defconfig updates are kept separate from other branches mostly to avoid conflicts between the different categories (driver branch enabling something that has context conflict with SoC options, etc).

ARM: SoC driver updates for v4.4
As we've enabled multiplatform kernels on ARM, and greatly done away with the contents under arch/arm/mach-*, there's still need for SoC-related drivers to go somewhere. Many of them go in through other driver trees, but we still have drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code that might be shared between ARM and ARM64 (or just in general makes sense to not have under the architecture directory). This branch contains mostly such code: - Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to communicate with power management blocks on these SoCs for use by clock, regulator and bus frequency drivers. - Allwinner Reduced Serial Bus driver, again used to communicate with PMICs. - Drivers for ARM's SCPI (System Control Processor). Not to be confused with PSCI (Power State Coordination Interface). SCPI is used to communicate with the assistant embedded cores doing power management, and we have yet to see how many of them will implement this for their hardware vs abstracting in other ways (or not at all like in the past). - To make confusion between SCPI and PSCI more likely, this release also includes an update of PSCI to interface version 1.0. - Rockchip support for power domains. - A driver to talk to the firmware on Raspberry Pi. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJWQC+cAAoJEIwa5zzehBx3jEUP/0GpxfDVanEUkudVLLe7J0RH CNlRan107Cw6hXRUJo7elEsuCALjccXjc1CAH4+RnNpOAeBKW97n+WU7trTv+wUZ sQX4SkBPKFBlgwGF2qhsi5q74gms/BrgtCa4kNb9joOYso039tlfIOPzK80DMkOm TkyIJdUCgFJMjCQLhX6kGT0PDcrbIjb6aA2cF3FAVeaJA7uz8lNe/eHJr3oHxIEY CvC651yJ2mIHQUU4BJx/AJo+wXg3dRUXNCAtBjwLRPEAzduYZXYm1ZTVIby/1q9r dR2KDFEuibODXmXrDBzKNJwCu/TLJEwo/1oPaEIVfY91XLKfiWUhgVqa1o1I+d9U XoGPibCW461qFahjQW87MfInALpCOA7/RbTNjFp+MVyipCYvkaYq7KFiYEldgFDx z4Qx/J4hYc2TlDWrpNiUCZMfmhwi7y+Ib+tnenYTO1eyMuw0e9mfnVdjk5iU3Pvk Ye4qPqpYclJruyHbYi164878+1lLaW2NCUgC3rkBO/GWPAzp7d9iLWoZ3PuyD5i5 PEjs668UcRdZYbI4rdrhGHL8Eq9Gnuc4Rthu7HxPOK+DG0XgP8r97PhM8aYGYVDO +yikBtjWRsA9fPj3rMKA3UsQ61DAeR9LmZ0XPGjWFMCjCG0JlUoIMaA+Uu0i8fr8 95qxBVxbO7rhL39r1rhV =dm+I -----END PGP SIGNATURE----- Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver updates from Olof Johansson: "As we've enabled multiplatform kernels on ARM, and greatly done away with the contents under arch/arm/mach-*, there's still need for SoC-related drivers to go somewhere.

arm64: remove redundant FRAME_POINTER kconfig option and force to select it
FRAME_POINTER is defined in lib/Kconfig.debug, it is unnecessary to redefine it in arch/arm64/Kconfig.debug. ARM64 depends on frame pointer to get correct stack trace (also selecting ARCH_WANT_FRAME_POINTERS). However, the lib/Kconfig.debug definition allows such option to be disabled. This patch forces FRAME_POINTER always on on arm64. Signed-off-by: Yang Shi <yang.shi@linaro.org> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> |

arm64: fix R/O permissions of FDT mapping
The mapping permissions of the FDT are set to 'PAGE_KERNEL | PTE_RDONLY' in an attempt to map the FDT as read-only. However, not only does this break at build time under STRICT_MM_TYPECHECKS (since the two terms are of different types in that case), it also results in both the PTE_WRITE and PTE_RDONLY attributes to be set, which means the region is still writable under ARMv8.1 DBM (and an attempted write will simply clear the PT_RDONLY bit). So instead, define PAGE_KERNEL_RO (which already has an established meaning across architectures) and use that instead.

mm, page_alloc: distinguish between being unable to sleep, unwilling to sleep and avoiding waking kswapd
__GFP_WAIT has been used to identify atomic context in callers that hold spinlocks or are in interrupts. They are expected to be high priority and have access one of two watermarks lower than "min" which can be referred to as the "atomic reserve". __GFP_HIGH users get access to the first lower watermark and can be called the "high priority reserve". Over time, callers had a requirement to not block when fallback options were available. Some have abused __GFP_WAIT leading to a situation where an optimisitic allocation with a fallback option can access atomic reserves. This patch uses __GFP_ATOMIC to identify callers that are truely atomic, cannot sleep and have no alternative. High priority users continue to use __GFP_HIGH. __GFP_DIRECT_RECLAIM identifies callers that can sleep and are willing to enter direct reclaim. __GFP_KSWAPD_RECLAIM to identify callers that want to wake kswapd for background reclaim. __GFP_WAIT is redefined as a caller that is willing to enter direct reclaim and wake kswapd for background reclaim. This patch then converts a number of sites o __GFP_ATOMIC is used by callers that are high priority and have memory pools for those requests. GFP_ATOMIC uses this flag. o Callers that have a limited mempool to guarantee forward progress clear __GFP_DIRECT_RECLAIM but keep __GFP_KSWAPD_RECLAIM. bio allocations fall into this category where kswapd will still be woken but atomic reserves are not used as there is a one-entry mempool to guarantee progress. o Callers that are checking if they are non-blocking should use the helper gfpflags_allow_blocking() where possible. This is because checking for __GFP_WAIT as was done historically now can trigger false positives. Some exceptions like dm-crypt.c exist where the code intent is clearer if __GFP_DIRECT_RECLAIM is used instead of the helper due to flag manipulations. o Callers that built their own GFP flags instead of starting with GFP_KERNEL and friends now also need to specify __GFP_KSWAPD_RECLAIM. The first key hazard to watch out for is callers that removed __GFP_WAIT and was depending on access to atomic reserves for inconspicuous reasons. In some cases it may be appropriate for them to use __GFP_HIGH. The second key hazard is callers that assembled their own combination of GFP flags instead of starting with something like GFP_KERNEL. They may now wish to specify __GFP_KSWAPD_RECLAIM. It's almost certainly harmless if it's missed in most cases as other activity will wake kswapd.

arm64: cmpxchg_dbl: fix return value type
The current arm64 __cmpxchg_double{_mb} implementations carry out the
compare exchange by first comparing the old values passed in to the
values read from the pointer provided and by stashing the cumulative
bitwise difference in a 64-bit register.
By comparing the register content against 0, it is possible to detect if
the values read differ from the old values passed in, so that the compare
exchange detects whether it has to bail out or carry on completing the
operation with the exchange.
Given the current implementation, to detect the cmpxchg operation
status, the __cmpxchg_double{_mb} functions should return the 64-bit
stashed bitwise difference so that the caller can detect cmpxchg failure
by comparing the return value content against 0. The current implementation
declares the return value as an int, which means that the 64-bit
value stashing the bitwise difference is truncated before being
returned to the __cmpxchg_double{_mb} callers, which means that
any bitwise difference present in the top 32 bits goes undetected,
triggering false positives and subsequent kernel failures.
This patch fixes the issue by declaring the arm64 __cmpxchg_double{_mb}
return values as a long, so that the bitwise difference is
properly propagated on failure, restoring the expected behaviour.

Power management and ACPI updates for v4.4-rc1
- ACPICA update to upstream revision 20150930 (Bob Moore, Lv Zheng). The most significant change is to allow the AML debugger to be built into the kernel. On top of that there is an update related to the NFIT table (the ACPI persistent memory interface) and a few fixes and cleanups. - ACPI CPPC2 (Collaborative Processor Performance Control v2) support along with a cpufreq frontend (Ashwin Chaugule). This can only be enabled on ARM64 at this point. - New ACPI infrastructure for the early probing of IRQ chips and clock sources (Marc Zyngier). - Support for a new hierarchical properties extension of the ACPI _DSD (Device Specific Data) device configuration object allowing the kernel to handle hierarchical properties (provided by the platform firmware this way) automatically and make them available to device drivers via the generic device properties interface (Rafael Wysocki). - Generic device properties API extension to obtain an index of certain string value in an array of strings, along the lines of of_property_match_string(), but working for all of the supported firmware node types, and support for the "dma-names" device property based on it (Mika Westerberg). - ACPI core fix to parse the MADT (Multiple APIC Description Table) entries in the order expected by platform firmware (and mandated by the specification) to avoid confusion on systems with more than 255 logical CPUs (Lukasz Anaczkowski). - Consolidation of the ACPI-based handling of PCI host bridges on x86 and ia64 (Jiang Liu). - ACPI core fixes to ensure that the correct IRQ number is used to represent the SCI (System Control Interrupt) in the cases when it has been re-mapped (Chen Yu). - New ACPI backlight quirk for Lenovo IdeaPad S405 (Hans de Goede). - ACPI EC driver fixes (Lv Zheng). - Assorted ACPI fixes and cleanups (Dan Carpenter, Insu Yun, Jiri Kosina, Rami Rosen, Rasmus Villemoes). - New mechanism in the PM core allowing drivers to check if the platform firmware is going to be involved in the upcoming system suspend or if it has been involved in the suspend the system is resuming from at the moment (Rafael Wysocki). This should allow drivers to optimize their suspend/resume handling in some cases and the changes include a couple of users of it (the i8042 input driver, PCI PM). - PCI PM fix to prevent runtime-suspended devices with PME enabled from being resumed during system suspend even if they aren't configured to wake up the system from sleep (Rafael Wysocki). - New mechanism to report the number of a wakeup IRQ that woke up the system from sleep last time (Alexandra Yates). - Removal of unused interfaces from the generic power domains framework and fixes related to latency measurements in that code (Ulf Hansson, Daniel Lezcano). - cpufreq core sysfs interface rework to make it handle CPUs that share performance scaling settings (represented by a common cpufreq policy object) more symmetrically (Viresh Kumar).

Second, ACPI gets a new infrastructure for the early probing of IRQ chips and clock sources (along the lines of the existing similar mechanism for DT). Next, the ACPI core and the generic device properties API will now support a recently introduced hierarchical properties extension of the _DSD (Device Specific Data) ACPI device configuration object. If the ACPI platform firmware uses that extension to organize device properties in a hierarchical way, the kernel will automatically handle it and make those properties available to device drivers via the generic device properties API. It also will be possible to build the ACPICA's AML interpreter debugger into the kernel now and use that to diagnose AML-related problems more efficiently. In the future, this should make it possible to single-step AML execution and do similar things. Interesting stuff, although somewhat experimental at this point. Finally, the PM core gets a new mechanism that can be used by device drivers to distinguish between suspend-to-RAM (based on platform firmware support) and suspend-to-idle (or other variants of system suspend the platform firmware is not involved in) and possibly optimize their device suspend/resume handling accordingly. In addition to that, some existing features are re-organized quite substantially. First, the ACPI-based handling of PCI host bridges on x86 and ia64 is unified and the common code goes into the ACPI core (so as to reduce code duplication and eliminate non-essential differences between the two architectures in that area). Second, the Operating Performance Points (OPP) framework is reorganized to make the code easier to find and follow. Next, the cpufreq core's sysfs interface is reorganized to get rid of the "primary CPU" concept for configurations in which the same performance scaling settings are shared between multiple CPUs. Finally, some interfaces that aren't necessary any more are dropped from the generic power domains framework. On top of the above we have some minor extensions, cleanups and bug fixes in multiple places, as usual. Specifics: - ACPICA update to upstream revision 20150930 (Bob Moore, Lv Zheng). The most significant change is to allow the AML debugger to be built into the kernel. On top of that there is an update related to the NFIT table (the ACPI persistent memory interface) and a few fixes and cleanups. - ACPI CPPC2 (Collaborative Processor Performance Control v2) support along with a cpufreq frontend (Ashwin Chaugule). This can only be enabled on ARM64 at this point. - New ACPI infrastructure for the early probing of IRQ chips and clock sources (Marc Zyngier). - Support for a new hierarchical properties extension of the ACPI _DSD (Device Specific Data) device configuration object allowing the kernel to handle hierarchical properties (provided by the platform firmware this way) automatically and make them available to device drivers via the generic device properties interface (Rafael Wysocki). - Generic device properties API extension to obtain an index of certain string value in an array of strings, along the lines of of_property_match_string(), but working for all of the supported firmware node types, and support for the "dma-names" device property based on it (Mika Westerberg). - ACPI core fix to parse the MADT (Multiple APIC Description Table) entries in the order expected by platform firmware (and mandated by the specification) to avoid confusion on systems with more than 255 logical CPUs (Lukasz Anaczkowski). - Consolidation of the ACPI-based handling of PCI host bridges on x86 and ia64 (Jiang Liu). - ACPI core fixes to ensure that the correct IRQ number is used to represent the SCI (System Control Interrupt) in the cases when it has been re-mapped (Chen Yu). - New ACPI backlight quirk for Lenovo IdeaPad S405 (Hans de Goede). - ACPI EC driver fixes (Lv Zheng). - Assorted ACPI fixes and cleanups (Dan Carpenter, Insu Yun, Jiri Kosina, Rami Rosen, Rasmus Villemoes). - New mechanism in the PM core allowing drivers to check if the platform firmware is going to be involved in the upcoming system suspend or if it has been involved in the suspend the system is resuming from at the moment (Rafael Wysocki). This should allow drivers to optimize their suspend/resume handling in some cases and the changes include a couple of users of it (the i8042 input driver, PCI PM). - PCI PM fix to prevent runtime-suspended devices with PME enabled from being resumed during system suspend even if they aren't configured to wake up the system from sleep (Rafael Wysocki). - New mechanism to report the number of a wakeup IRQ that woke up the system from sleep last time (Alexandra Yates). - Removal of unused interfaces from the generic power domains framework and fixes related to latency measurements in that code (Ulf Hansson, Daniel Lezcano). - cpufreq core sysfs interface rework to make it handle CPUs that share performance scaling settings (represented by a common cpufreq policy object) more symmetrically (Viresh Kumar). This should help to simplify the CPU offline/online handling among other things. - cpufreq core fixes and cleanups (Viresh Kumar). - intel_pstate fixes related to the Turbo Activation Ratio (TAR) mechanism on client platforms which causes the turbo P-states range to vary depending on platform firmware settings (Srinivas Pandruvada). - intel_pstate sysfs interface fix (Prarit Bhargava). - Assorted cpufreq driver (imx, tegra20, powernv, integrator) fixes and cleanups (Bai Ping, Bartlomiej Zolnierkiewicz, Shilpasri G Bhat, Luis de Bethencourt). - cpuidle mvebu driver cleanups (Russell King). - OPP (Operating Performance Points) framework code reorganization to make it more maintainable (Viresh Kumar). - Intel Broxton support for the RAPL (Running Average Power Limits) power capping driver (Amy Wiles). - Assorted power management code fixes and cleanups (Dan Carpenter, Geert Uytterhoeven, Geliang Tang, Luis de Bethencourt, Rasmus Villemoes)" * tag 'pm+acpi-4.4-rc1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (108 commits) cpufreq: postfix policy directory with the first CPU in related_cpus cpufreq: create cpu/cpufreq/policyX directories cpufreq: remove cpufreq_sysfs_{create|remove}_file() cpufreq: create cpu/cpufreq at boot time cpufreq: Use cpumask_copy instead of cpumask_or to copy a mask cpufreq: ondemand: Drop unnecessary locks from update_sampling_rate() PM / Domains: Merge measurements for PM QoS device latencies PM / Domains: Don't measure ->start|stop() latency in system PM callbacks PM / clk: Fix broken build due to non-matching code and header #ifdefs ACPI / Documentation: add copy_dsdt to ACPI format options ACPI / sysfs: correctly check failing memory allocation ACPI / video: Add a quirk to force native backlight on Lenovo IdeaPad S405 ACPI / CPPC: Fix potential memory leak ACPI / CPPC: signedness bug in register_pcc_channel() ACPI / PAD: power_saving_thread() is not freezable ACPI / PM: Fix incorrect wakeup IRQ setting during suspend-to-idle ACPI: Using correct irq when waiting for events ACPI: Use correct IRQ when uninstalling ACPI interrupt handler cpuidle: mvebu: disable the bind/unbind attributes and use builtin_platform_driver cpuidle: mvebu: clean up multiple platform drivers ... |
