In the effort to remove all VLAs from the kernel[1], it is desirable to build with -Wvla. However, this warning is overly pessimistic, in that it is only happy with stack array sizes that are declared as constant expressions, and not constant values. One case of this is the evaluation of the max() macro which, due to its construction, ends up converting constant expression arguments into a constant value result. All attempts to rewrite this macro with __builtin_constant_p() failed with older compilers (e.g. gcc 4.4)[2]. However, Martin Uecker, constructed[3] a mind-shattering solution that works everywhere. Cthulhu fhtagn! This patch updates the min()/max() macros to evaluate to a constant expression when called on constant expression arguments. This removes several false-positive stack VLA warnings from an x86 allmodconfig build when -Wvla is added: $ diff -u before.txt after.txt | grep ^- -drivers/input/touchscreen/cyttsp4_core.c:871:2: warning: ISO C90 forbids variable length array ‘ids’ [-Wvla] -fs/btrfs/tree-checker.c:344:4: warning: ISO C90 forbids variable length array ‘namebuf’ [-Wvla] -lib/vsprintf.c:747:2: warning: ISO C90 forbids variable length array ‘sym’ [-Wvla] -net/ipv4/proc.c:403:2: warning: ISO C90 forbids variable length array ‘buff’ [-Wvla] -net/ipv6/proc.c:198:2: warning: ISO C90 forbids variable length array ‘buff’ [-Wvla] -net/ipv6/proc.c:218:2: warning: ISO C90 forbids variable length array ‘buff64’ [-Wvla] This also updates two cases where different enums were being compared and explicitly casts them to int (which matches the old side-effect of the single-evaluation code): one in tpm/tpm_tis_core.h, and one in drm/drm_color_mgmt.c.

Pull sound updates from Takashi Iwai: "This became a large update. The changes are scattered widely, and the majority of them are attributed to ASoC componentization. The gitk output made me dizzy, but it's slightly better than London tube. OK, below are some highlights: - Continued hardening works in ALSA PCM core; most of the existing syzkaller reports should have been covered. - USB-audio got the initial USB Audio Class 3 support, as well as UAC2 jack detection support and more DSD-device support. - ASoC componentization: finally each individual driver was converted to components framework, which is more future-proof for further works. Most of conversations were systematic. - Lots of fixes for Intel Baytrail / Cherrytrail devices with Realtek codecs, typically tablets and small PCs. - Fixes / cleanups for Samsung Odroid systems - Cleanups in Freescale SSI driver - New ASoC drivers: * AKM AK4458 and AK5558 codecs * A few AMD based machine drivers * Intel Kabylake machine drivers * Maxim MAX9759 codec * Motorola CPCAP codec * Socionext Uniphier SoCs * TI PCM1789 and TDA7419 codecs - Retirement of Blackfin drivers along with architecture removal" * tag 'sound-4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (497 commits) ALSA: pcm: Fix UAF at PCM release via PCM timer access ALSA: usb-audio: silence a static checker warning ASoC: tscs42xx: Remove owner assignment from i2c_driver ASoC: mediatek: remove "simple-mfd" in the example ASoC: cpcap: replace codec to component ASoC: Intel: bytcr_rt5651: don't use codec anymore ASoC: amd: don't use codec anymore ALSA: usb-audio: fix memory leak on cval ALSA: pcm: Fix mutex unbalance in OSS emulation ioctls ASoC: topology: Fix kcontrol name string handling ALSA: aloop: Mark paused device as inactive ALSA: usb-audio: update clock valid control ALSA: usb-audio: UAC2 jack detection ALSA: pcm: Return -EBUSY for OSS ioctls changing busy streams ALSA: pcm: Avoid potential races between OSS ioctls and read/write ALSA: usb-audio: Integrate native DSD support for ITF-USB based DACs.

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.17 kernel cycle: New drivers: - Nintendo Wii GameCube GPIO, known as "Hollywood" - Raspberry Pi mailbox service GPIO expander - Spreadtrum main SC9860 SoC and IEC GPIO controllers. Improvements: - Implemented .get_multiple() callback for most of the high-performance industrial GPIO cards for the ISA bus. - ISA GPIO drivers now select the ISA_BUS_API instead of depending on it. This is merged with the same pattern for all the ISA drivers and some other Kconfig cleanups related to this. Cleanup: - Delete the TZ1090 GPIO drivers following the deletion of this SoC from the ARM tree. - Move the documentation over to driver-api to conform with the rest of the kernel documentation build. - Continue to make the GPIO drivers include only <linux/gpio/driver.h> and not the too broad <linux/gpio.h> that we want to get rid of. - Managed to remove VLA allocation from two drivers pending more fixes in this area for the next merge window. - Misc janitorial fixes" * tag 'gpio-v4.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (77 commits) gpio: Add Spreadtrum PMIC EIC driver support gpio: Add Spreadtrum EIC driver support dt-bindings: gpio: Add Spreadtrum EIC controller documentation gpio: ath79: Fix potential NULL dereference in ath79_gpio_probe() pinctrl: qcom: Don't allow protected pins to be requested gpiolib: Support 'gpio-reserved-ranges' property gpiolib: Change bitmap allocation to kmalloc_array gpiolib: Extract mask allocation into subroutine dt-bindings: gpio: Add a gpio-reserved-ranges property gpio: mockup: fix a potential crash when creating debugfs entries gpio: pca953x: add compatibility for pcal6524 and pcal9555a gpio: dwapb: Add support for a bus clock gpio: Remove VLA from xra1403 driver gpio: Remove VLA from MAX3191X driver gpio: ws16c48: Implement get_multiple callback gpio: gpio-mm: Implement get_multiple callback gpio: 104-idi-48: Implement get_multiple callback gpio: 104-dio-48e: Implement get_multiple callback gpio: pcie-idio-24: Implement get_multiple/set_multiple callbacks gpio: pci-idio-16: Implement get_multiple callback ...

Pull staging/IIO updates from Greg KH: "Here is the big set of Staging/IIO driver patches for 4.17-rc1. It is a lot, over 500 changes, but not huge by previous kernel release standards. We deleted more lines than we added again (27k added vs. 91k remvoed), thanks to finally being able to delete the IRDA drivers and networking code. We also deleted the ccree crypto driver, but that's coming back in through the crypto tree to you, in a much cleaned-up form. Added this round is at lot of "mt7621" device support, which is for an embedded device that Neil Brown cares about, and of course a handful of new IIO drivers as well.

We might have a bit more stuff land later in the merge window, but I wanted to get this out earlier just so everyone can see where we currently stand. A short summary of the changes is: - We've added support for dynamic ftrace on RISC-V targets. - There have been a handful of cleanups to our atomic and locking routines. They now more closely match the released RISC-V memory model draft. - Our module loading support has been cleaned up and is now enabled by default, despite some limitations still existing. - A patch to define COMMANDLINE_FORCE instead of COMMANDLINE_OVERRIDE so the generic device tree code picks up handling all our command line stuff.

The touch sensor buttons on Sony VAIO VGN-CS series laptops (e.g. VGN-CS31S) are a separate PS/2 device. As the MUX is disabled for all VAIO machines by the nomux blacklist, the data from touch sensor buttons and touchpad are combined. The protocol used by the buttons is probably similar to the touchpad protocol (both are Synaptics) so both devices get enabled. The controller combines the data, creating a mess which results in random button clicks, touchpad stopping working and lost sync error messages: psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 4 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: issuing reconnect request Add a new i8042_dmi_forcemux_table whitelist with VGN-CS. With MUX enabled, touch sensor buttons are detected as separate device (and left disabled as there's currently no driver), fixing all touchpad problems. Signed-off-by:

Pull arm64 updates from Will Deacon: "Nothing particularly stands out here, probably because people were tied up with spectre/meltdown stuff last time around.

Clock MONOTONIC behaves now exactly like clock BOOTTIME and does not longer ignore the time spent in suspend.

It might be possible to change that annotation so it has no effect for loadable modules, but I have not figured out exactly how to do that, and we want this to be fixed in -rc1.

Giving an integer to proc_doulongvec_minmax() is dangerous on 64bit arches, since linker might place next to it a non zero value preventing a change to ip6frag_low_thresh. ip6frag_low_thresh is not used anymore in the kernel, but we do not want to prematuraly break user scripts wanting to change it. Since specifying a minimal value of 0 for proc_doulongvec_minmax() is moot, let's remove these zero values in all defrag units.

After commit 694aba69 ("ipv4: factorize sk_wmem_alloc updates done by __ip_append_data()") and commit 1f4c6eb2 ("ipv6: factorize sk_wmem_alloc updates done by __ip6_append_data()"), when transmitting sub MTU datagram, an addtional, unneeded atomic operation is performed in ip*_append_data() to update wmem_alloc: in the above condition the delta is 0. The above cause small but measurable performance regression in UDP xmit tput test with packet size below MTU. This change avoids such overhead updating wmem_alloc only if wmem_alloc_delta is non zero. The error path is left intentionally unmodified: it's a slow path and simplicity is preferred to performances.
