Kai-Heng Feng ce9d58d3ea HID: usbhid: Add quirk for Redragon/Dragonrise Seymur 2
Redragon Seymur 2 stops working since commit 190d7f02ce ("HID: input:
do not increment usages when a duplicate is found").

Use quirk HID_QUIRK_INCREMENT_USAGE_ON_DUPLICATE suggested by the commit
can solve the issue.

Jason Gerecke 11db8173db HID: wacom: Work around HID descriptor bug in DTK-2451 and DTH-2452
The DTK-2451 and DTH-2452 have a buggy HID descriptor which incorrectly
contains a Cintiq-like report, complete with pen tilt, rotation, twist, serial
number, etc. The hardware doesn't actually support this data but our driver
duitifully sets up the device as though it does. To ensure userspace has a
correct view of devices without updated firmware, we clean up this incorrect
data in wacom_setup_device_quirks.

We're also careful to clear the WACOM_QUIRK_TOOLSERIAL flag since its presence
causes the driver to wait for serial number information (via
wacom_wac_pen_serial_enforce) that never comes, resulting in
the pen being non-responsive.

Hans de Goede afbb1169ed HID: i2c-hid: Remove RESEND_REPORT_DESCR quirk and its handling
Commit 52cf93e63e ("HID: i2c-hid: Don't reset device upon system resume")
removes the need for the RESEND_REPORT_DESCR quirk for Raydium devices, but
kept it for the SIS device id 10FB touchscreens, as the author of that
commit could not determine if the quirk is still necessary there.

I've tested suspend/resume on a Toshiba Click Mini L9W-B which is the
device for which this quirk was added in the first place and with the
"Don't reset device upon system resume" fix the quirk is no longer
necessary, so this commit removes it.

Note even better I also had some other devices with SIS touchscreens which
suspend/resume issues, where the RESEND_REPORT_DESCR quirk did not help.

I've also tested these devices with the "Don't reset device upon system
resume" fix and I'm happy to report that that fix also fixes touchscreen
resume on the following devices:

Asus T100HA
Asus T200TA
Peaq C1010

Anisse Astier 807588ac92 HID: i2c-hid: disable runtime PM operations on hantick touchpad
This hantick HTIX5288 touchpad can quickly fall in a wrong state if
there are too many open/close operations. This will either make it stop
reporting any input, or will shift all the input reads by a few bytes,
making it impossible to decode.

Here, we never release the probed touchpad runtime pm while the driver
is loaded, which should disable all runtime pm suspend/resumes.

This fast repetition of sleep/wakeup is also more likely to happen when
using runtime PM, which is why the quirk is done there, and not for all
power downs, which would include suspend or module removal.

Kai-Heng Feng 52cf93e63e HID: i2c-hid: Don't reset device upon system resume
Raydium touchscreen triggers interrupt storm after system-wide suspend:

	[ 179.085033] i2c_hid i2c-CUST0000:00: i2c_hid_get_input: incomplete report (58/65535)

According to Raydium, Windows driver does not reset the device after system
resume.

The HID over I2C spec does specify a reset should be used at intialization, but
it doesn't specify if reset is required for system suspend.

Tested this patch on other i2c-hid touchpanels I have and those touchpanels do
work after S3 without doing reset. If any regression happens to other
touchpanel vendors, we can use quirk for Raydium devices.

There's still one device uses I2C_HID_QUIRK_RESEND_REPORT_DESCR so keep it
there.

Hans de Goede ade573eb1e HID: sensor-hub: Restore fixup for Lenovo ThinkPad Helix 2 sensor hub report
Commit b0f847e16c ("HID: hid-sensor-hub: Force logical minimum to 1 for
power and report state") not only replaced the descriptor fixup done for
devices with the HID_SENSOR_HUB_ENUM_QUIRK with a generic fix, but also
accidentally removed the unrelated descriptor fixup for the Lenovo ThinkPad
Helix 2 sensor hub. This commit restores this fixup.

Restoring this fixup not only fixes the Lenovo ThinkPad Helix 2's sensors,
but also the Lenovo ThinkPad 8's sensors.

Benjamin Tissoires 0d6c301140 HID: core: fix grouping by application
commit f07b3c1da9 ("HID: generic: create one input report per
application type") was effectively the same as MULTI_INPUT:
hidinput->report was never set, so hidinput_match_application()
always returned null.

Fix that by testing against the real application.

Note that this breaks some old eGalax touchscreens that expect MULTI_INPUT
instead of HID_QUIRK_INPUT_PER_APP. Enable this quirk for backward
compatibility on all non-Win8 touchscreens.

Benjamin Tissoires ec6adef5fb HID: multitouch: fix Elan panels with 2 input modes declaration
When implementing commit 7f81c8db54 ("HID: multitouch: simplify

that made sure we never try to set the second InputMode feature
to something else than 0.

This broke badly some recent Elan panels that now forget to send the
click button in some area of the touchpad.

Joe Perches cafa0010cd Raise the minimum required gcc version to 4.6
Various architectures fail to build properly with older versions of the
gcc compiler.

An example from Guenter Roeck in thread [1]:
>
>   In file included from ./include/linux/mm.h:17:0,
>                    from ./include/linux/pid_namespace.h:7,
>                    from ./include/linux/ptrace.h:10,
>                    from arch/openrisc/kernel/asm-offsets.c:32:
>   ./include/linux/mm_types.h:497:16: error: flexible array member in otherwise empty struct
>
> This is just an example with gcc 4.5.1 for or32. I have seen the problem
> with gcc 4.4 (for unicore32) as well.

So update the minimum required version of gcc to 4.6.

[1] https://lore.kernel.org/lkml/20180814170904.GA12768@roeck-us.net/

Miscellanea:

 - Update Documentation/process/changes.rst

 - Remove and consolidate version test blocks in compiler-gcc.h for
   versions lower than 4.6

Tony Luck cc26ebbebd ia64: Fix kernel BUG at lib/ioremap.c:72!
Commit 0bbf47eab4 ("ia64: use asm-generic/io.h") results in a BUG
while booting ia64.  This is because asm-generic/io.h defines
PCI_IOBASE, which results in the function acpi_pci_root_remap_iospace()
doing a lot of unnecessary (and wrong) things.

I'd suggested an #if !CONFIG_IA64 in the functon, but Arnd suggested
keeping the fix inside the arch/ia64 tree.

Vlad Buslov 653cd284a8 net: sched: always disable bh when taking tcf_lock
Recently, ops->init() and ops->dump() of all actions were modified to
always obtain tcf_lock when accessing private action state. Actions that
don't depend on tcf_lock for synchronization with their data path use
non-bh locking API. However, tcf_lock is also used to protect rate
estimator stats in softirq context by timer callback.

Change ops->init() and ops->dump() of all actions to disable bh when using
tcf_lock to prevent deadlock reported by following lockdep warning:

Linus Torvalds e61cf2e3a5 Minor code cleanups for PPC.
For x86 this brings in PCID emulation and CR3 caching for shadow page
 tables, nested VMX live migration, nested VMCS shadowing, an optimized
 IPI hypercall, and some optimizations.
 
 ARM will come next week.
 
 There is a semantic conflict because tip also added an .init_platform
 callback to kvm.c.  Please keep the initializer from this branch,
 and add a call to kvmclock_init (added by tip) inside kvm_init_platform
 (added here).
 
 Also, there is a backmerge from 4.18-rc6.  This is because of a
 refactoring that conflicted with a relatively late bugfix and
 resulted in a particularly hellish conflict.  Because the conflict
 was only due to unfortunate timing of the bugfix, I backmerged and
 rebased the refactoring rather than force the resolution on you.

Linus Torvalds 1009aa1205 RISC-V Updates for the 4.19 Merge Window
This tag contains some major improvements to the RISC-V port, including
 the necessary interrupt controller and timer support to actually make it
 to userspace.  Support for three devices has been added:
 
 * Support for the ISA-mandated timers on RISC-V systems.
 * Support for the ISA-mandated first-level interrupt controller on
   RISC-V systems, which is handled as part of our core arch code because
   it's very small and tightly tied to the ISA.
 * Support for SiFive's platform-level interrupt controller, which talks
   to the actual devices.
 
 In addition to these new devices, there are a handful of cleanups all
 over the RISC-V tree:
 
 * Build fixes for various configurations
     * A fix to the vDSO build's makefile so it respects CFLAGS.
     * The addition of __lshrti3, a libgcc derived function necessary for
       some 32-bit configurations.
     * !SMP && PERF_EVENTS
 * Cleanups to the arch code to remove the remnants of old versions of
   the drivers that were just properly submitted.
     * Some dead code from the timer driver, most of which wasn't ever
       even compiled.
     * Cleanups of some interrupt #defines, which are now local to the
       interrupt handling code.
 * Fixes to ptrace(), which while not being sufficient to fully make GDB
   work are at least sufficient to get simple GDB tasks to work.
 * Early printk support via RISC-V's architecturally mandated SBI console
   device.
 * A fix to our early debug trap handler to ensure it's always aligned.
 
 These patches have all been through a fairly extensive review process,
 but as this enables a whole pile of functionality (ie, userspace) I'm
 confident we'll need to submit a few more patches.  The only concrete
 issues I know about are the sys_riscv_flush_icache patches, but as I
 managed to screw those up on Friday I figured it'd be best to let them
 bake another week.
 
 This tag boots a Fedora root filesystem on QEMU's master branch for me,
 and before this morning's rebase (from 4.18-rc8 to 4.18) it booted on
 the HiFive Unleashed.
 
 Thanks to Christoph Hellwig and the other guys at WD for getting the new
 drivers in shape!
