2017-04-20HID: wacom: Override incorrect logical maximum contact identifierJason Gerecke
It apears that devices designed around Wacom's G11 chipset (e.g. Lenovo ThinkPad Yoga 260, Lenovo ThinkPad X1 Yoga, Dell XPS 12 9250, Dell Venue 8 Pro 5855, etc.) suffer from a common issue in their HID descriptors. The logical maximum is not updated for the "Contact Identifier" usage, leaving it as just "1" despite these devices being capable of tracking far more touches. Commit 60a221869803 began ignoring usages with out-of-range values, causing problems for devices based on this chipset. Touches after the first will have an out-of-range Contact Identifier, and ignoring that usage will cause the kernel to incorrectly slot each finger's events (along with all the knock-on userspace effects that entails). This commit checks for these buggy descriptors and updates the maximum where required. Prior chipsets have used "255" as the maximum (and the G11, at least, doesn't seem to actually use IDs outside the range of 1..CONTACTMAX) so continue using this value.

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core Pull perf/core cleanups from Arnaldo Carvalho de Melo: - Introduce new header files out of the hodge-podge that util/util.h became, trying to disentangle the includes hell that all C projects end up growing. This should help in build times, as changes to seemingly unrelated files (util.h included tons of headers) won't trigger a rebuild of most object files. - Use equivalent facilities found in the kernel source code base originated tools/include/ header files, such as __stringify(), ARRAY_SIZE, that has extra checks (__must_be_array()), etc. - For that get some more files from the kernel sources, like include/linux/bug.h, some just with the bits needed at this time. - Use the headers where facilities declared in them are used, such as PRIxu(32,64) macros (inttypes.h), errno defines (errno.h), etc. - Remove various leftovers from the initial code base we copied from git.git: FLEX_ARRAY, etc. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2017-04-20x86/reboot: Turn off KVM when halting a CPUTiantian Feng
A CPU in VMX root mode will ignore INIT signals and will fail to bring up the APs after reboot. Therefore, on a panic we disable VMX on all CPUs before rebooting or triggering kdump. Do this when halting the machine as well, in case a firmware-level reboot does not perform a cold reset for all processors. Without doing this, rebooting the host may hang.

2017-04-20x86/boot: Fix BSS corruption/overwrite bug in early x86 kernel startupAshish Kalra
The minimum size for a new stack (512 bytes) setup for arch/x86/boot components when the bootloader does not setup/provide a stack for the early boot components is not "enough". The setup code executing as part of early kernel startup code, uses the stack beyond 512 bytes and accidentally overwrites and corrupts part of the BSS section. This is exposed mostly in the early video setup code, where it was corrupting BSS variables like force_x, force_y, which in-turn affected kernel parameters such as screen_info (screen_info.orig_video_cols) and later caused an exception/panic in console_init(). Most recent boot loaders setup the stack for early boot components, so this stack overwriting into BSS section issue has not been exposed.

2017-04-20rtlwifi: btcoex: 21a 2ant: finer adjustment of bt powerYan-Hsuan Chuang
Originally we only increase/decrease bt power in a fixed power gap, this patch makes us be able to modify bt power for multiple power gaps and we can precisely adjust the bt power.

2017-04-20rtlwifi: btcoex: 21a 2ant: monitor wifi counter to check network statusYan-Hsuan Chuang
If there are a lot of low-rate packets, then the connection of wifi is unstable. If so, we should switch resource to bt to have a higher transmission quality, or wifi resource will be wasted Signed-off-by: Yan-Hsuan Chuang <yhchuang@realtek.com> Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Cc: Pkshih <pkshih@realtek.com> Cc: Birming Chiu <birming@realtek.com> Cc: Shaofu <shaofu@realtek.com> Cc: Steven Ting <steventing@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2017-04-20rtlwifi: btcoex: 21a 2ant: monitor if bt is slave or notYan-Hsuan Chuang
We monitor the packet counter to guess if the bt is slave or not, and when bt is slave, it may receive packet at any time, so we will have to take care about it Signed-off-by: Yan-Hsuan Chuang <yhchuang@realtek.com> Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Cc: Pkshih <pkshih@realtek.com> Cc: Birming Chiu <birming@realtek.com> Cc: Shaofu <shaofu@realtek.com> Cc: Steven Ting <steventing@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2017-04-20rtlwifi: btcoex: 21a 2ant: limit rx aggregation size to avoid bt interruptYan-Hsuan Chuang
Larger packets have higher opportunity to be interrupt by bt signal. In order to shorten the transmission time, control the packet aggregation size.
