Dmitry Torokhov 62d7846144 Revert "Input: synaptics - fix handling of disabling gesture mode"
This reverts commit e51e38494a8ecc18650efb0c840600637891de2c: we
actually do want the device to work in extended W mode, as this is the
mode that allows us receiving multiple contact information.

Andrew Morton 09a59a9d57 drivers/input/joystick/Kconfig: zhenhua.c needs BITREVERSE

Dmitry Vyukov 218c1f76b8 Input: psmouse - fix data race in __ps2_command
The data race happens on ps2dev->cmdcnt and ps2dev->cmdbuf contents.
__ps2_command reads that data concurrently with the interrupt handler. As
the result, for example, if a response arrives just after the timeout,
__ps2_command can copy out garbage from ps2dev->cmdbuf but then see that
ps2dev->cmdcnt is 0 and return success.

Stop the interrupt handler with serio_pause_rx() before reading the
results.

The data race was found with KernelThreadSanitizer (KTSAN).

Dmitry Torokhov 72d4736253 Input: uinput - fix crash when using ABS events
Commit b6d30968d8 (Input: uinput - switch to
using for_each_set_bit()) switched driver to use for_each_set_bit().
However during initial write of the uinput structure that contains min/max
data for all possible axes none of them are reflected in dev->absbit yet
and so we were skipping over all of them and were not allocating absinfo
memory which caused crash later when driver tried to sens EV_ABS events:

Daniel Drake 9d7b03f863 Input: elan_i2c - don't require known iap version
The Asus X456UA has an ELAN1000 touchpad with IAP version 0xe.  This is
unknown to elan_get_fwinfo() so driver probe fails and I am left with an
unusable touchpad.

However, the fwinfo is not required for general driver usage, it is only
needed if the user decides to upload new firmware.

Adjust the driver so that we do not abort probe when we encounter
unexpected IAP version, but rather warn user that firmware update feature
of the driver will not work.

2015-09-10 16:21:11 -07:00
Julien Grall 0df4f266b3 xen: Use correctly the Xen memory terminologies
Based on include/xen/mm.h [1], Linux is mistakenly using MFN when GFN
is meant, I suspect this is because the first support for Xen was for
PV. This resulted in some misimplementation of helpers on ARM and
confused developers about the expected behavior.

For instance, with pfn_to_mfn, we expect to get an MFN based on the name.
Although, if we look at the implementation on x86, it's returning a GFN.

For clarity and avoid new confusion, replace any reference to mfn with
gfn in any helpers used by PV drivers. The x86 code will still keep some
reference of pfn_to_mfn which may be used by all kind of guests
No changes as been made in the hypercall field, even
though they may be invalid, in order to keep the same as the defintion
in xen repo.

Note that page_to_mfn has been renamed to xen_page_to_gfn to avoid a
name to close to the KVM function gfn_to_page.

Take also the opportunity to simplify simple construction such
as pfn_to_mfn(page_to_pfn(page)) into xen_page_to_gfn. More complex clean up
will come in follow-up patches.

Linus Torvalds abebcdfb64 sound updates for 4.3-rc1
There are little changes in core part, but lots of development are
 found in drivers, especially ASoC.  The diffstat shows regmap-
 related changes for a slight API additions / changes, and that's all.
 
 Looking at the code size statistics, the most significant addition
 is for Intel Skylake.  (Note that SKL support is still underway, the
 codec driver is missing.)  Also STI controller driver is a major
 addition as well as a few new codec drivers.
 
 In HD-audio side, there are fewer changes than the past.  The
 noticeable change is the support of ELD notification from i915
 graphics driver.  Thus this pull request carries a few changes in
 drm/i915.
 
 Other than that, USB-audio got a rewrite of runtime PM code.  It
 was initiated by lockdep warning, but resulted in a good cleanup in
 the end.
 
 Below are the highlights:
 
 Common:
 - Factoring out of AC'97 reset code from ASoC into the core helper
 - A few regmap API extensions (in case it's not pulled yet)
 
 ASoC:
 - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
   RT298 and ST STI controllers
 - Machine drivers for Rockchip systems with MAX98090 and RT5645 and
   RT5650
 - Initial driver support for Intel Skylake devices
 - Lots of rsnd cleanup and enhancements
 - A few DAPM fixes and cleanups
 - A large number of cleanups in various drivers (conversion and
   standardized to regmap, component) mostly by Lars-Peter and Axel
 
 HD-audio:
 - Extended HD-audio core for Intel Skylake controller support
 - Quirks for Dell headsets, Alienware 15
 - Clean up of pin-based quirk tables for Realtek codecs
 - ELD notifier implenetation for Intel HDMI/DP
 
 USB-audio:
 - Refactor runtime PM code to make lockdep happier

Takashi Iwai eb38f3a4f6 Input: evdev - do not report errors form flush()
We've got bug reports showing the old systemd-logind (at least
system-210) aborting unexpectedly, and this turned out to be because
of an invalid error code from close() call to evdev devices.  close()
is supposed to return only either EINTR or EBADFD, while the device
returned ENODEV.  logind was overreacting to it and decided to kill
itself when an unexpected error code was received.  What a tragedy.

The bad error code comes from flush fops, and actually evdev_flush()
returns ENODEV when device is disconnected or client's access to it is
revoked. But in these cases the fact that flush did not actually happen is
not an error, but rather normal behavior. For non-disconnected devices
result of flush is also not that interesting as there is no potential of
data loss and even if it fails application has no way of handling the
error. Because of that we are better off always returning success from
evdev_flush().

Also returning EINTR from flush()/close() is discouraged (as it is not
clear how application should handle this error), so let's stop taking
evdev->mutex interruptibly.

Pull MIPS updates from Ralf Baechle:
 "This is the main pull request for 4.3 for MIPS.  Here's the summary:

  Three fixes that didn't make 4.2-stable:

   - a -Os build might compile the kernel using the MIPS16 instruction
     set but the R2 optimized inline functions in <uapi/asm/swab.h> are
     implemented using 32-bit wide instructions which is invalid.

   - a build error in pgtable-bits.h for a particular kernel
     configuration.

   - accessing registers of the CM GCR might have been compiled to use
     64 bit accesses but these registers are onl 32 bit wide.

  And also a few new bits:

   - move the ATH79 GPIO driver to drivers/gpio

   - the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h,
     change ATH79 accordingly.

   - fix definition of pgprot_writecombine

   - add an implementation of dma_map_ops.mmap

   - fix alignment of quiet build output for vmlinuz link

   - BCM47xx: Use kmemdup rather than duplicating its implementation

   - Netlogic: Fix 0x0x prefixes of constants.

   - merge Bjorn Helgaas' series to remove most of the weak keywords
     from function declarations.

   - CP0 and CP1 registers are best considered treated as unsigned
     values to avoid large values from becoming negative values.

   - improve support for the MIPS GIC timer.

   - enable common clock framework for Malta and SEAD3.

   - a number of improvments and fixes to dump_tlb().

   - document the MIPS TLB dump functionality in Magic SysRq.

   - Cavium Octeon CN68XX improvments.

   - NetLogic improvments.

   - irq: Use access helper irq_data_get_affinity_mask.

   - handle MSA unaligned accesses.

   - a number of R6-related math-emu fixes.

   - support for I6400.

   - improvments to MSA support.

   - add uprobes support.

   - move from deprecated __initcall to arch_initcall.

   - remove finish_arch_switch().

   - IRQ cleanups by Thomas Gleixner.

   - migrate to new 'set-state' interface.

   - random small cleanups"

Alban Bedel 832f5dacfa MIPS: Remove all the uses of custom gpio.h
Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS
machines, and each machine type provides its own gpio.h. However
only a handful really implement the GPIO API, most just forward
everythings to gpiolib.

The Alchemy machine is notable as it provides a system to allow
implementing the GPIO API at the board level. But it is not used by
any board currently supported, so it can also be removed.

For most machine types we can just remove the custom gpio.h, as well
as the custom wrappers if some exists. Some of the code found in
the wrappers must be moved to the respective GPIO driver.

A few more fixes are need in some drivers as they rely on linux/gpio.h
to provides some machine specific definitions, or used asm/gpio.h
instead of linux/gpio.h for the gpio API.
