xfs-for-linus-4.1-rc1
542c3118 · ·xfs: update for 4.1-rc1 This update contains: o RENAME_WHITEOUT support o conversion of per-cpu superblock accounting to use generic counters o new inode mmap lock so that we can lock page faults out of truncate, hole punch and other direct extent manipulation functions to avoid racing mmap writes from causing data corruption o rework of direct IO submission and completion to solve data corruption issue when running concurrent extending DIO writes. Also solves problem of running IO completion transactions in interrupt context during size extending AIO writes. o FALLOC_FL_INSERT_RANGE support for inserting holes into a file via direct extent manipulation to avoid needing to copy data within the file o attribute block header field overflow fix for 64k block size filesystems o Lots of changes to log messaging to be more informative and concise when errors occur. Also prevent a lot of unnecessary log spamming due to cascading failures in error conditions. o lots of cleanups and bug fixes

gpio-v4.1-1
03daa6f8 · ·This is the bulk of GPIO changes for the v4.1 development cycle: - A new GPIO hogging mechanism has been added. This can be used on boards that want to drive some GPIO line high, low, or set it as input on boot and then never touch it again. For some embedded systems this is bliss and simplifies things to a great extent. - Some API cleanup and closure: gpiod_get_array() and gpiod_put_array() has been added to get and put GPIOs in bulk as was possible with the non-descriptor API. - Encapsulate cross-calls to the pin control subsystem in <linux/gpio/driver.h>. Now this should be the only header any GPIO driver needs to include or something is wrong. Cleanups restricting drivers to this include are welcomed if tested. - Sort the GPIO Kconfig and split it into submenus, as it was becoming and unstructured, illogical and unnavigatable mess. I hope this is easier to follow. Menus that require a certain subsystem like I2C can now be hidden nicely for example, still working on others. - New drivers: - New driver for the Altera Soft GPIO. - The F7188x driver now handles the F71869 and F71869A variants. - The MIPS Loongson driver has been moved to drivers/gpio for consolidation and cleanup. - Cleanups: - The MAX732x is converted to use the GPIOLIB_IRQCHIP infrastructure. - The PCF857x is converted to use the GPIOLIB_IRQCHIP infrastructure. - Radical cleanup of the OMAP driver. - Misc: - Enable the DWAPB GPIO for all architectures. This is a "hard IP" block from Synopsys which has started to turn up in so diverse architectures as X86 Quark, ARC and a slew of ARM systems. So even though it's not an expander, it's generic enough to be available for all. - We add a mock GPIO on Crystalcove PMIC after a long discussion with Daniel Vetter et al, tracing back to the shootout at the kernel summit where DRM drivers and sub-componentization was discussed. In this case a mock GPIO is assumed to be the best compromise gaining some reuse of infrastructure without making DRM drivers overly complex at the same time. Let's see. -
acpica-4.1-rc1
0ee0d349 · ·ACPICA updates for v4.1-rc1 - Fix for a GPE handling regression on Dell Latitude D600 that caused GPE signaling to stop working on that machine, which appears to be due to a hardware glitch, but it used to work and it can be made work again in a relativly straightforward way (Rafael J Wysocki). - Fix for a mutex unlock regression related to the handling of ACPI tables introduced during the 3.16 development cycle (Octavian Purdila). - _REV modification to always return 2 which has been done by all versions of Windows since NT and the firmware people started to use it to distinguish between OSes in their AML and do some silly and wrong things on that basis (Bob Moore). - Fixes and cleanups related to the acpi_physicall_address data type including one stable-candidate fix for an issue occasionally occuring on 64-bit machines running 32-bit kernels where using offsets provided by the firmware may lead to address overflows (Lv Zheng). - External() opcode support infrastructure needed for recompiling disassembled ACPI tables in some cases including interpreter modification to ignore that opcode (Bob Moore). - Support for the "Windows 2015" string in _OSI (Bob Moore). - GPE debug interface change to return values read from hardware registers (Lv Zheng). - Removal of the __DATE__ macro usage in tools (Rasmus Villemoes). - Assorted minor fixes and cleanups (Lv Zheng, Rickard Strandqvist, Bob Moore). /

b2d5fb97 · ·Power management and ACPI fixes for v4.0-rc8 - Revert a 3.17 hibernate commit that was supposed to fix an issue related to e820 reserved regions, but broke resume from hibernation on Lenovo x230 (Rafael J Wysocki). - Prevent the ACPI cpuidle driver from overwriting the name and description of the C0 state set by the core when the list of C-states changes (Thomas Schlichter). - Remove the no longer needed state_count field from struct cpuidle_device which prevents the list of C-states shown by the sysfs interface from becoming incorrect when the current number of them is different from the number of C-states on boot (Bartlomiej Zolnierkiewicz). - The cpufreq core updates the policy object of the only online CPU during system resume to make it reflect the current hardware state, but it always assumes that CPU to be CPU0 which need not be the case, so fix the code to avoid that assumption (Viresh Kumar). /
