Commit c7f0522a uses sixteen bits of data in the construction of 'strip1' and 'strip2'. This can cause problems in some cases, however, since some tablets store flags in the MSB of data[2] and data[4] that should not be included in these values. This restores the 0x1f mask that used prior to c7f0522a. Signed-off-by: Jason Gerecke <jason.gerecke@wacom.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

Smatch complains that these should probably be bitwise ORs instead of logical. It doesn't matter for "prox" but it makes a difference for "strip1" and "strip2".

When splitting the touch-only "BAMBOO_TOUCH" type out of the existing "BAMBOO_PT" type in 3b164a00, the lowres quirk was not updated so that it would continue to apply to these devices (effectively only the 0xD0). The absence of this quirk does not significantly impact usability, but is a correctness issue nonetheless.

"INTUOSREAD" and "INTUOSWRITE" are poorly named. These are report IDs for pen ID (proximity) packets. It should be noted that the latter is only used on Intuos/Intuos2 for a second stylus when DualTrack is in use.

Make the logic for reading X, Y, distance, and pressure a bit more clear. An additional bit was stuffed into the packet format many models back, and /most/ devices in use will use it. If we happen to be dealing with a particularly old tablet, just shift it off the end to pretend we never read it.

Reasoning through the conditions under which a particular block of code in 'wacom_intuos_general' will be reached is not at all easy due to the sheer number of magic masks and comparisons. Remove these and replace them with a switch statement over the various 'types' of packets that will be encountered.

It was rather annoying that you can only see and modify tracer options after enabling the tracer. Now they are in the options/ directory even when the tracer is not active. Although they are still only visible when the tracer is active in the trace_options file. - Trace options are now per instance (although some of the tracer specific options are global) - New tracefs file: set_event_pid.

This reverts commit af19161a, which breaks the omap3 device tree build due to a wrong reference. I accidently queued this change via the power supply subsystem while telling Marek at the same time, that it should go through Tony. Following that I did miss Stephen's messages about the build failure in linux-next and since he switched to merging an older snapshot nobody else noticed the problem in my tree. I didn't notice myself, since I did not build any device tree files assuming none have changed by me.

Pull sound updates from Takashi Iwai: "Here is the first batch of updates for sound system on 4.4-rc1. Again at this time, the update looks fairly calm; no big changes in either ALSA core or ASoC infrastructures, rather all small cleanups, in addition to the new stuff as usual. The biggest changes are about Firewire sound devices. It gained lots of new device support, and MIDI functionality. Also there are updates for a few still working-in-progress stuff (topology API and ASoC skylake), too. But overall, this update should give no big surprise. Some highlights are below: Core: - A few more Kconfig items for tinification; it's marked as EXPERT, so normal user should't be bothered :) - Refactoring with a new PCM hw_constraint helper - Removal of unused transfer_ack_{begin,end} PCM callbacks Firewire: - Restructuring of code subtree, lots of refactoring - Support AMDTP variants - New driver for Digidesign 002/003 family - Adds support for TASCAM FireOne to ALSA OXFW driver - Add MIDI support to TASCAM and Digi00x devices HD-Audio: - Automated modalias generation for codec drivers, finally - Improvement on heuristics for setting mixer name - A few fixes for longstanding bugs on Creative CA0132 cards - Addition of audio rate callback with i915 communication - Fix suspend issue on recent Dell XPS - Intel Lewisburg controller support ASoC: - Updates to the topology userspace interface - Big updates to the Renesas support (rcar) - More updates for supporting Intel Sky Lake systems - New drivers for Asahi Kasei Microdevices AK4613, Allwinnner A10, Cirrus Logic WM8998, Dialog DA7219, Nuvoton NAU8825, Rockchip S/PDIF, and Atmel class D amplifier USB-Audio: - A fix for newer Roland MIDI devices - Quirks and workarounds for Zoom R16/24 device Misc: - A few fixes for some old Cirrus CS46xx PCI sound boards - Yet another fixes for some old ESS Maestro3 PCI sound boards" * tag 'sound-4.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (330 commits) ALSA: hda - Add Intel Lewisburg device IDs Audio ALSA: hda - Apply pin fixup for HP ProBook 6550b ALSA: hda - Fix lost 4k BDL boundary workaround ALSA: maestro3: Fix Allegro mute until master volume/mute is touched ALSA: maestro3: Enable docking support for Dell Latitude C810 ALSA: firewire-digi00x: add another rawmidi character device for MIDI control ports ALSA: firewire-digi00x: add MIDI operations for MIDI control port ALSA: firewire-digi00x: rename identifiers of MIDI operation for physical ports ALSA: cs46xx: Fix suspend for all channels ALSA: cs46xx: Fix Duplicate front for CS4294 and CS4298 codecs ALSA: DocBook: Add soc-ops.c and soc-compress.c ALSA: hda - Add / fix kernel doc comments ALSA: Constify ratden/ratnum constraints ALSA: hda - Disable 64bit address for Creative HDA controllers ALSA: hda/realtek - Dell XPS one ALC3260 speaker no sound after resume back ALSA: hda/ca0132 - Convert leftover pr_info() and pr_err() ASoC: fsl: Use #ifdef instead of #if for CONFIG_PM_SLEEP ASoC: rt5645: Sort the order for register bit defines ASoC: dwc: add check for master/slave format ASoC: rt5645: Add the HWEQ for the speaker output ...

There are multiple types of users of mtd->reboot_notifier.notifier_call: (1) A while back, the cfi_cmdset_000{1,2} chip drivers implemented a reboot notifier to (on a best effort basis) attempt to reset their flash chips before rebooting. (2) More recently, we implemented a common _reboot() hook so that MTD drivers (particularly, NAND flash) could better halt I/O operations without having to reimplement the same notifier boilerplate. Currently, the WARN_ONCE() condition here was written to handle (2), but at the same time it mis-diagnosed case (1) as an already-registered MTD. Let's fix this by having the WARN_ONCE() condition better imitate the condition that immediately follows it. (Wow, I don't know how I missed that one.) (Side note: Unfortunately, we can't yet combine the reboot notifier code for (1) and (2) with a patch like [1], because some users of (1) also use mtdconcat, and so the mtd_info struct from cfi_cmdset_000{1,2} won't actually get registered with mtdcore, and therefore their reboot notifier won't get registered.)

It turns out that we still have issues with the EFI memory map that ends up polluting our kernel page tables with writable executable pages. That will get sorted out, but in the meantime let's not make the scary complaint about them be on by default. The code is useful for developers, but not ready for end user testing yet.

Test the mmap() flag, and the mlockall() flag. These tests ensure that pages are not faulted in until they are accessed, that the pages are unevictable once faulted in, and that VMA splitting and merging works with the new VM flag. The second test ensures that mlock limits are respected. Note that the limit test needs to be run a normal user. Also add tests to use the new mlock2 family of system calls.

The previous patch introduced a flag that specified pages in a VMA should be placed on the unevictable LRU, but they should not be made present when the area is created. This patch adds the ability to set this state via the new mlock system calls. We add MLOCK_ONFAULT for mlock2 and MCL_ONFAULT for mlockall. MLOCK_ONFAULT will set the VM_LOCKONFAULT modifier for VM_LOCKED. MCL_ONFAULT should be used as a modifier to the two other mlockall flags. When used with MCL_CURRENT, all current mappings will be marked with VM_LOCKED | VM_LOCKONFAULT. When used with MCL_FUTURE, the mm->def_flags will be marked with VM_LOCKED | VM_LOCKONFAULT. When used with both MCL_CURRENT and MCL_FUTURE, all current mappings and mm->def_flags will be marked with VM_LOCKED | VM_LOCKONFAULT. Prior to this patch, mlockall() will unconditionally clear the mm->def_flags any time it is called without MCL_FUTURE. This behavior is maintained after adding MCL_ONFAULT. If a call to mlockall(MCL_FUTURE) is followed by mlockall(MCL_CURRENT), the mm->def_flags will be cleared and new VMAs will be unlocked. This remains true with or without MCL_ONFAULT in either mlockall() invocation. munlock() will unconditionally clear both vma flags. munlockall() unconditionally clears for VMA flags on all VMAs and in the mm->def_flags field.
