GUI environments seem to be becoming more agressive at scanning filesystems, to the point where autofs cannot expire mounts at all. This is one key reason the update of the autofs dentry info last_used field is done in the expire system when the dentry is seen to be in use. But somewhere along the way instances of the update has crept back into the autofs path walk functions which, with the more aggressive file access patterns, is preventing expiration. Changing the update in the path walk functions allows autofs to at least make progress in spite of frequent immediate re-mounts from file accesses.

Often all is needed is these small helpers, instead of compiler.h or a full kprobes.h. This is important for asm helpers, in fact even some asm/kprobes.h make use of these helpers... instead just keep a generic asm file with helpers useful for asm code with the least amount of clutter as possible. Likewise we need now to also address what to do about this file for both when architectures have CONFIG_HAVE_KPROBES, and when they do not. Then for when architectures have CONFIG_HAVE_KPROBES but have disabled CONFIG_KPROBES. Right now most asm/kprobes.h do not have guards against CONFIG_KPROBES, this means most architecture code cannot include asm/kprobes.h safely. Correct this and add guards for architectures missing them. Additionally provide architectures that not have kprobes support with the default asm-generic solution. This lets us force asm/kprobes.h on the header include/linux/kprobes.h always, but most importantly we can now safely include just asm/kprobes.h on architecture code without bringing the full kitchen sink of header files. Two architectures already provided a guard against CONFIG_KPROBES on its kprobes.h: sh, arch. The rest of the architectures needed gaurds added. We avoid including any not-needed headers on asm/kprobes.h unless kprobes have been enabled. In a subsequent atomic change we can try now to remove compiler.h from include/linux/kprobes.h. During this sweep I've also identified a few architectures defining a common macro needed for both kprobes and ftrace, that of the definition of the breakput instruction up. Some refer to this as BREAKPOINT_INSTRUCTION. This must be kept outside of the #ifdef CONFIG_KPROBES guard.

Change the zpool/compressor param callback function to release the zswap_pools_lock spinlock before calling param_set_charp, since that function may sleep when it calls kmalloc with GFP_KERNEL. While this problem has existed for a while, I wasn't able to trigger it using a tight loop changing either/both the zpool and compressor params; I think it's very unlikely to be an issue on the stable kernels, especially since most zswap users will change the compressor and/or zpool from sysfs only one time each boot - or zero times, if they add the params to the kernel boot. Fixes: c99b42c3 ("zswap: use charp for zswap param strings") Link: http://lkml.kernel.org/r/20170126155821.4545-1-ddstreet@ieee.orgSigned-off-by:

If either the compressor and/or zpool param are invalid at boot, and their default value is also invalid, set the param to the empty string to indicate there is no compressor and/or zpool configured. This allows users to check the sysfs interface to see which param needs changing. Link: http://lkml.kernel.org/r/20170124200259.16191-4-ddstreet@ieee.orgSigned-off-by:

The Kconfig currently controlling compilation of this code is: drivers/platform/x86/Kconfig:config INTEL_TURBO_MAX_3 drivers/platform/x86/Kconfig: bool "Intel Turbo Boost Max Technology 3.0 enumeration driver" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments. We do uncover some implicit includes during build coverage that were hidden behind the module.h which pulls in a lot of dependants.

platform/x86: thinkpad_acpi: Call led_classdev_notify_brightness_hw_changed on kbd brightness change Make thinkpad_acpi call led_classdev_notify_brightness_hw_changed on the kbd_led led_classdev registered by thinkpad_acpi when the kbd backlight brightness is changed through the hotkey. This will allow userspace to monitor (poll) for brightness changes on these LEDs caused by the hotkey. Signed-off-by:

Now a days the LED core can take care of executing brightness_set from a workqueue if it needs to sleep, make use of this and remove a bunch of DIY code for this. Since this commit removes the workqueue usage for LEDs, the led_sysfs_blink_set callback may now also sleep, this is fine. Signed-off-by:

There is no need to set the led_classdev's brightness value from its set_brightness callback, this is taken care of by the led-core and thinkpad_acpi really should not be mucking with it. Note that kbdlight_set_level_and_update() is still used by the old thinpad_acpi specific sysfs interface for the led, so we cannot remove it. Signed-off-by:

Some LEDs may have their brightness level changed autonomously (outside of kernel control) by hardware / firmware. This commit adds support for an optional brightness_hw_changed attribute to signal such changes to userspace (if a driver can detect them): What: /sys/class/leds/<led>/brightness_hw_changed Date: January 2017 KernelVersion: 4.11 Description: Last hardware set brightness level for this LED. Some LEDs may be changed autonomously by hardware/firmware. Only LEDs where this happens and the driver can detect this, will have this file. This file supports poll() to detect when the hardware changes the brightness. Reading this file will return the last brightness level set by the hardware, this may be different from the current brightness. Drivers which want to support this, simply add LED_BRIGHT_HW_CHANGED to their flags field and call led_classdev_notify_brightness_hw_changed() with the hardware set brightness when they detect a hardware / firmware triggered brightness change.

Now that we have informed the firmware that the RF Button driver is active, laptops such as the Acer TravelMate P238-M will generate a WMI key event with code 0x86 when the Fn+F3 airplane mode key is pressed. Add this keycode to the table so that it is converted to an appropriate input event. Signed-off-by:

The same method to activate LM(Launch Manager) can also be used to activate the RF Button driver with different bit toggled in the same lm_status. To express that many functions this byte field can achieve, rename the lm_status to app_status. And also the app_mask is the bit mask which specifically indicate which bits are going to be changed. This solves a problem where the AR9565 wifi included in the Acer Aspire ES1-421 is permanently hard blocked according to the rfkill GPIO read by ath9k. Signed-off-by:

Some Asus machines use 0x4/0x5 as their LED on/off values, while others use 0x0/0x1, as shown in the DSDT excerpts below. Luckily it seems this behavior is tied to different HIDs, after looking at 44 DSDTs from different Asus models. Another small difference is that a few of them call GWBL instead of OWGS, and SWBL instead of OWGD. That does not seem to make a difference for asus-wireless, and is additional reasoning to not try to call these methods directly.

This patch adds the PCI Device id for Power Management Controller on Intel Apollo Lake platforms. Intel PMC IPC Driver loads as a platform driver on Apollo Lake platforms since Intel BIOS hides the PCI Configuration space for 0:13:1 and re-enumerates it as ACPI device (INT34D2). The correct PCI Device ID should be added if some platform firmware choses to enumerate the device via PCI space. Signed-off-by:

This patch adds a new API to indicate S0ix residency in usec. It utilizes the PMC Global Control Registers (GCR) to read deep and shallow S0ix residency. PMC MMIO resources: o Lower 4kB: IPC1 (PMC inter-processor communication) interface o Upper 4kB: GCR (Global Control Registers) This enables the power management framework to take corrective actions when the platform fails to enter S0ix after kernel freeze as part of the suspend to idle flow. (echo freeze > /sys/power/state). This is expected to be used with a S0ix failsafe framework such as: <https://lwn.net/Articles/689505/> [rajneesh: folded in "fix division in 32-bit case" from Andy Shevchenko] Signed-off-by:Shanth Murthy <shanth.murthy@intel.com> [andy: fixed kbuild error, removed "total" from variables, fixed macro] Signed-off-by:
