2018-01-23drm/amdgpu: Avoid leaking PM domain on driver unbind (v2)Alex Deucher
We only support vga_switcheroo and runtime pm on PX/HG systems so forcing runpm to 1 doesn't do anything useful anyway. Only call vga_switcheroo_init_domain_pm_ops() for PX/HG so that the cleanup path is correct as well.

2018-01-23nfp: fix fw dump handling of absolute rtsym sizeCarl Heymann
Fix bug that causes _absolute_ rtsym sizes of > 8 bytes (as per symbol table) to result in incorrect space used during a TLV-based debug dump. Detail: The size calculation stage calculates the correct size (size of the rtsym address field == 8), while the dump uses the size in the table to calculate the TLV size to reserve. Symbols with size <= 8 are handled OK due to aligning sizes to 8, but including any absolute symbol with listed size > 8 leads to an ENOSPC error during the dump.

2018-01-23HID: quirks: Fix keyboard + touchpad on Toshiba Click Mini not workingHans de Goede
The Toshiba Click Mini uses an i2c attached keyboard/touchpad combo (single i2c_hid device for both) which has a vid:pid of 04F3:0401, which is also used by a bunch of Elan touchpads which are handled by the drivers/input/mouse/elan_i2c driver, but that driver deals with pure touchpads and does not work for a combo device such as the one on the Toshiba Click Mini. The combo on the Mini has an ACPI id of ELAN0800, which is not claimed by the elan_i2c driver, so check for that and if it is found do not ignore the device. This fixes the keyboard/touchpad combo on the Mini not working (although with the touchpad in mouse emulation mode).

2018-01-23SUNRPC: Micro-optimize __rpc_executeChuck Lever
The common case: There are 13 to 14 actions per RPC, and tk_callback is non-NULL in only one of them. There's no need to store a NULL in the tk_callback field during each FSM step.

2018-01-23HID: wacom: Fix reporting of touch toggle (WACOM_HID_WD_MUTE_DEVICE) eventsJason Gerecke
Touch toggle softkeys send a '1' while pressed and a '0' while released, requring the kernel to keep track of wether touch should be enabled or disabled. The code does not handle the state transitions properly, however. If the key is pressed repeatedly, the following four states of states are cycled through (assuming touch starts out enabled): Press: shared->is_touch_on => 0, SW_MUTE_DEVICE => 1 Release: shared->is_touch_on => 0, SW_MUTE_DEVICE => 1 Press: shared->is_touch_on => 1, SW_MUTE_DEVICE => 0 Release: shared->is_touch_on => 1, SW_MUTE_DEVICE => 1 The hardware always properly enables/disables touch when the key is pressed but applications that listen for SW_MUTE_DEVICE events to provide feedback about the state will only ever show touch as being enabled while the key is held, and only every-other time. This sequence occurs because the fallthrough WACOM_HID_WD_TOUCHONOFF case is always handled, and it uses the value of the *local* is_touch_on variable as the value to report to userspace. The local value is equal to the shared value when the button is pressed, but equal to zero when the button is released. Reporting the shared value to userspace fixes this problem, but the fallthrough case needs to update the shared value in an incompatible way (which is why the local variable was introduced in the first place). To work around this, we just handle both cases in a single block of code and update the shared variable as appropriate.

2018-01-23HID: elecom: rewrite report fixup for EX-G and future miceTomasz Kramkowski
This patch rewrites the mouse report fixup used for the DEFT and HUGE elecom trackballs in order to make it generic enough to fix other elecom mice with similar issues. This patch also uses this new report fixup function to fix the Elecom EX-G trackball which has 6 physical buttons and a similar issue to the other two mice. Elecom's track record has so far shown that they like to re-use the same report descriptor for multiple different mice regardless of the number of buttons the mouse has. This means that the missing buttons on multiple mice can be fixed in one function without introducing phantom buttons which would in turn cause the number of mouse buttons to be misreported to userspace. This patch drops the very verbose report descriptor "diff" comment for a more abridged yet hopefully just as informative generic version.

2018-01-23HID: wacom: EKR: ensure devres groups at higher indexes are releasedAaron Armstrong Skomra
Background: ExpressKey Remotes communicate their events via usb dongle. Each dongle can hold up to 5 pairings at one time and one EKR (identified by its serial number) can unfortunately be paired with its dongle more than once. The pairing takes place in a round-robin fashion. Input devices are only created once per EKR, when a new serial number is seen in the list of pairings. However, if a device is created for a "higher" paring index and subsequently a second pairing occurs at a lower pairing index, unpairing the remote with that serial number from any pairing index will currently cause a driver crash. This occurs infrequently, as two remotes are necessary to trigger this bug and most users have only one remote. As an illustration, to trigger the bug you need to have two remotes, and pair them in this order: 1. slot 0 -> remote 1 (input device created for remote 1) 2. slot 1 -> remote 1 (duplicate pairing - no device created) 3. slot 2 -> remote 1 (duplicate pairing - no device created) 4. slot 3 -> remote 1 (duplicate pairing - no device created) 5. slot 4 -> remote 2 (input device created for remote 2) 6. slot 0 -> remote 2 (1 destroyed and recreated at slot 1) 7. slot 1 -> remote 2 (1 destroyed and recreated at slot 2) 8. slot 2 -> remote 2 (1 destroyed and recreated at slot 3) 9. slot 3 -> remote 2 (1 destroyed and not recreated) 10. slot 4 -> remote 2 (2 was already in this slot so no changes) 11. slot 0 -> remote 1 (The current code sees remote 2 was paired over in one of the dongle slots it occupied and attempts to remove all information about remote 2 [1]. It calls wacom_remote_destroy_one for remote 2, but the destroy function assumes the lowest index is where the remote's input device was created. The code "cleans up" the other remote 2 pairings including the one which the input device was based on, assuming they were were just duplicate pairings. However, the cleanup doesn't call the devres release function for the input device that was created in slot 4). This issue is fixed by this commit. [1] Remote 2 should subsequently be re-created on the next packet from the EKR at the lowest numbered slot that it occupies (here slot 1).

These features are detected manually by perf's Makefile.config so they can't be displayed with the main list, but only after we're done in Makefile.config. $ make VF=1 BUILD: Doing 'make -j4' parallel build Auto-detecting system features: ... dwarf: [ on ] ... dwarf_getlocations: [ on ] ... glibc: [ on ] ... gtk2: [ on ] SNIP ... timerfd: [ on ] ... sched_getcpu: [ on ] ... sdt: [ on ] ... setns: [ on ] extra features: ... bionic: [ OFF ] ... compile-32: [ on ] ... compile-x32: [ OFF ] ... cplus-demangle: [ on ] ... hello: [ OFF ] ... libbabeltrace: [ on ] ... liberty: [ on ] ... liberty-z: [ on ] ... libunwind-debug-frame: [ OFF ] ... libunwind-debug-frame-arm: [ OFF ] ... libunwind-debug-frame-aarch64: [ OFF ] SNIP Signed-off-by: Jiri Olsa <jolsa@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Mathieu Poirier <mathieu.poirier@linaro.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/20180109092646.GB11520@krava Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2018-01-23perf report: Fix regression when decoding intel_pt tracesMathieu Poirier
Commit (93d10af26bb7 perf tools: Optimize sample parsing for ordered events) breaks intelPT trace decoding by invariably returning an error if the event type isn't a PERF_SAMPLE_TIME. With this patch the timestamp is initialised and processing is allowed to continue if the error returned by function perf_evlist__parse_sample_timestamp() is not a fault.

2018-01-23perf symbols: Using O_CLOEXEC in do_openWang YanQing
I've meet a strange behavior with these commands on my gentoo box: 1: perf kmem record 2: CTRL-C to stop 1 3: perf report 4: "Enter", "Enter", "Run scripts for all samples", "event_analyzing_sample". Then 'perf report' says: " No kallsyms or vmlinux with build-id xxxx was found /lib/modules/4.10.0+/build/vmlinux with build id xxxx not found, continuing without symbols ". It is strange because I am sure /lib/modules/4.10.0+/build/vmlinux is right for perf.data. After digging, I found out the reason is that "perf report" generates many open fds, then "script_browse" uses popen to run "perf script" which run out of open files. The gentoo box has a small default value for "max open files", 1024. Yes, "ulimit -n " with a bigger number could fix it, but I think that using O_CLOEXEC in do_open is a better way.
