2019-07-16drm/amd/powerplay: fix save dpm level error for smuKevin Wang
the save dpm level should be save previous dpm profile level, should not modified by get dpm level function. eg: default auto 1. auto -> standard ==> dpm_level = standard, save_dpm = auto. 2. standard -> auto ==> dpm_level = auto, save_dpm = standard.

2019-07-16Merge branch 'proc-cmdline' (/proc/<pid>/cmdline fixes)Linus Torvalds
This fixes two problems reported with the cmdline simplification and cleanup last year: - the setproctitle() special cases didn't quite match the original semantics, and it can be noticeable: https://lore.kernel.org/lkml/alpine.LNX.2.21.1904052326230.3249@kich.toxcorp.com/ - it could leak an uninitialized byte from the temporary buffer under the right (wrong) circustances: https://lore.kernel.org/lkml/20190712160913.17727-1-izbyshev@ispras.ru/ It rewrites the logic entirely, splitting it into two separate commits (and two separate functions) for the two different cases ("unedited cmdline" vs "setproctitle() has been used to change the command line"). * proc-cmdline: /proc/<pid>/cmdline: add back the setproctitle() special case /proc/<pid>/cmdline: remove all the special cases

2019-07-16/proc/<pid>/cmdline: add back the setproctitle() special caseLinus Torvalds
This makes the setproctitle() special case very explicit indeed, and handles it with a separate helper function entirely. In the process, it re-instates the original semantics of simply stopping at the first NUL character when the original last NUL character is no longer there. [ The original semantics can still be seen in mm/util.c: get_cmdline() that is limited to a fixed-size buffer ] This makes the logic about when we use the string lengths etc much more obvious, and makes it easier to see what we do and what the two very different cases are. Note that even when we allow walking past the end of the argument array (because the setproctitle() might have overwritten and overflowed the original argv[] strings), we only allow it when it overflows into the environment region if it is immediately adjacent. [ Fixed for missing 'count' checks noted by Alexey Izbyshev ] Link: https://lore.kernel.org/lkml/alpine.LNX.2.21.1904052326230.3249@kich.toxcorp.com/ Fixes: 5ab827189965 ("fs/proc: simplify and clarify get_mm_cmdline() function") Cc: Jakub Jankowski <shasta@toxcorp.com> Cc: Alexey Dobriyan <adobriyan@gmail.com> Cc: Alexey Izbyshev <izbyshev@ispras.ru> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2019-07-16/proc/<pid>/cmdline: remove all the special casesLinus Torvalds
Start off with a clean slate that only reads exactly from arg_start to arg_end, without any oddities. This simplifies the code and in the process removes the case that caused us to potentially leak an uninitialized byte from the temporary kernel buffer. Note that in order to start from scratch with an understandable base, this simplifies things _too_ much, and removes all the legacy logic to handle setproctitle() having changed the argument strings. We'll add back those special cases very differently in the next commit.

2019-07-16ACPI: video: Add new hw_changes_brightness quirk, set it on PB Easynote MZ35Hans de Goede
Some machines change the brightness themselves when a brightness hotkey gets pressed, despite us telling them not to. This causes the brightness to go two steps up / down when the hotkey is pressed. This is esp. a problem on older machines with only a few brightness levels. This commit adds a new hw_changes_brightness quirk which makes acpi_video_device_notify() only call backlight_force_update(..., BACKLIGHT_UPDATE_HOTKEY) and not do anything else, notifying userspace that the brightness was changed and leaving it at that fixing the dual step problem.

2019-07-16ALSA: hda/hdmi - Fix i915 reverse port/pin mappingTakashi Iwai
The recent fix for Icelake HDMI codec introduced the mapping from pin NID to the i915 gfx port number. However, it forgot the reverse mapping from the port number to the pin NID that is used in the ELD notifier callback.

2019-07-16Revert "gpio/spi: Fix spi-gpio regression on active high CS"Linus Walleij
This reverts commit fbbf145a0e0a0177e089c52275fbfa55763e7d1d. It seems I was misguided in my fixup, which was working at the time but did not work on the final v5.2. The patch tried to avoid a quirk the gpiolib code not to treat "spi-gpio" CS gpios "special" by enforcing them to be active low, in the belief that since the "spi-gpio" driver was parsing the device tree on its own, it did not care to inspect the "spi-cs-high" attribute on the device nodes. That's wrong. The SPI core was inspecting them inside the of_spi_parse_dt() funtion and setting SPI_CS_HIGH on the nodes, and the driver inspected this flag when driving the line. As of now, the core handles the GPIO and it will consistently set the GPIO descriptor to 1 to enable CS, strictly requireing the gpiolib to invert it. And the gpiolib should indeed enforce active low on the CS line. Device trees should of course put the right flag on the GPIO handles, but it used to not matter. If we don't enforce active low on "gpio-gpio" we may run into ABI backward compatibility issues, so revert this.

2019-07-16ALSA: seq: Break too long mutex context in the write loopTakashi Iwai
The fix for the racy writes and ioctls to sequencer widened the application of client->ioctl_mutex to the whole write loop. Although it does unlock/relock for the lengthy operation like the event dup, the loop keeps the ioctl_mutex for the whole time in other situations. This may take quite long time if the user-space would give a huge buffer, and this is a likely cause of some weird behavior spotted by syzcaller fuzzer. This patch puts a simple workaround, just adding a mutex break in the loop when a large number of events have been processed. This shouldn't hit any performance drop because the threshold is set high enough for usual operations.

RHBZ: 1722704 In low memory situations the various SMB2_*_init() functions can fail to allocate a request PDU and thus leave the request iovector as NULL. If we don't check the return code for failure we end up calling smb2_set_next_command() with a NULL iovector causing a crash when it tries to dereference it.

2019-07-15selftests/bpf: make directory prerequisites order-onlyIlya Leoshkevich
When directories are used as prerequisites in Makefiles, they can cause a lot of unnecessary rebuilds, because a directory is considered changed whenever a file in this directory is added, removed or modified. If the only thing a target is interested in is the existence of the directory it depends on, which is the case for selftests/bpf, this directory should be specified as an order-only prerequisite: it would still be created in case it does not exist, but it would not trigger a rebuild of a target in case it's considered changed.
