git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Second set of IIO fixes for the 4.9 cycle. Interestingly scale related fixes for accelerometers at both ends of the range. Obviously more varied devices turning up than we've seen before! * ad5933 - fix an uninitialized value in a return case that is winding up GCC. * hid sensors - missing pm function prevents hid rotations sensors from working on newer ISH hubs (works by luck on older ones) - increase of scale precision needed to fix a case where on a yoga 260 the reported scale is 0 (presumably a high precision but very low g sensor). * st_sensors - fix an issue seen with the hs3lis331dl where the range is much greater than previous devices (100's of g) and hence the per bit scale is greater than 1.
2016-11-07mmc: dw_mmc: add the "reset" as name of reset controllerJaehoon Chung1-1/+1
Add the "reset" as name of reset controller. This is for preventing the wrong operation. Even if some SoC has reset controller, doesn't define "resets" in device-tree. Then it might be waiting for reset controller and it should be stuck.

2016-11-06mm/filemap: don't allow partially uptodate page for pipesEryu Guan1-0/+3
Starting from 4.9-rc1 kernel, I started noticing some test failures of sendfile(2) and splice(2) (sendfile0N and splice01 from LTP) when testing on sub-page block size filesystems (tested both XFS and ext4), these syscalls start to return EIO in the tests. e.g. sendfile02 1 TFAIL : sendfile02.c:133: sendfile(2) failed to return expected value, expected: 26, got: -1 sendfile02 2 TFAIL : sendfile02.c:133: sendfile(2) failed to return expected value, expected: 24, got: -1 sendfile02 3 TFAIL : sendfile02.c:133: sendfile(2) failed to return expected value, expected: 22, got: -1 sendfile02 4 TFAIL : sendfile02.c:133: sendfile(2) failed to return expected value, expected: 20, got: -1 This is because that in sub-page block size cases, we don't need the whole page to be uptodate, only the part we care about is uptodate is OK (if fs has ->is_partially_uptodate defined). But page_cache_pipe_buf_confirm() doesn't have the ability to check the partially-uptodate case, it needs the whole page to be uptodate. So it returns EIO in this case. This is a regression introduced by commit 82c156f85384 ("switch generic_file_splice_read() to use of ->read_iter()"). Prior to the change, generic_file_splice_read() doesn't allow partially-uptodate page either, so it worked fine. Fix it by skipping the partially-uptodate check if we're working on a pipe in do_generic_file_read(), so we read the whole page from disk as long as the page is not uptodate.

Commit efd9e03facd0 ("arm64: Use static keys for CPU features") introduced support for static keys in asm/cpufeature.h, including linux/jump_label.h. When CC_HAVE_ASM_GOTO is not defined, this causes a circular dependency via linux/atomic.h, asm/lse.h and asm/cpufeature.h. This patch moves the capability macros out out of asm/cpufeature.h into a separate asm/cpucaps.h and modifies some of the #includes accordingly.

interpretation. While testing, it was observed that on some platforms the scale value from iio sysfs for gyroscope is always 0 (E.g. Yoga 260). This results in the final angular velocity component values to be zeros. This is caused by insufficient precision of scale value displayed in sysfs. If the precision is changed to nano from current micro, then this is sufficient to display the scale value on this platform. Since this can be a problem for all other HID sensors, increase scale precision of all HID sensors to nano from current micro.

2016-11-05HID: sensor: fix attributes in HID sensor interfaceOoi, Joyce1-3/+3
User is unable to access to input-X-yyy and feature-X-yyy where X is a hex value and more than 9 (e.g. input-a-yyy, feature-b-yyy) in HID sensor custom sysfs interface. This is because when creating the attribute, the attribute index is written to using %x (hex). However, when reading and writing values into the attribute, the attribute index is scanned using %d (decimal). Hence, user is unable to access to attributes with index in hex values (e.g. 'a', 'b', 'c') but able to access to attributes with index in decimal values (e.g. 1, 2, 3,..). This fix will change input-%d-%x-%s and feature-%d-%x-%s to input-%x-%x-%s and feature-%x-%x-%s in show_values() and store_values() accordingly.

When the system is suspended to S3 the BIOS might re-initialize certain GPIO pins back to their original state or it may re-program interrupt mask of others. For example Acer TravelMate B116-M had BIOS bug where certain GPIO pin (MF_ISH_GPIO_5) was programmed to trigger on high level, and the pin state was high once the BIOS gave control to the OS on resume. This triggers lots of messages like: irq 117, desc: ffff88017a61e600, depth: 1, count: 0, unhandled: 0 ->handle_irq(): ffffffff8109b613, handle_bad_irq+0x0/0x1e0 ->irq_data.chip(): ffffffffa0020180, chv_pinctrl_exit+0x2d84/0x12 [pinctrl_cherryview] ->action(): (null) IRQ_NOPROBE set We reset the mask back to known state in chv_pinctrl_resume() but that is called only after device interrupts have already been enabled. Now, this particular issue was fixed by upgrading the BIOS to the latest (v1.23) but not everybody upgrades their BIOSes so we fix it up in the driver as well. Prevent the possible interrupt storm by moving suspend and resume hooks to be called at _noirq time instead. Since device interrupts are still disabled we can restore the mask back to known state before interrupt storm happens.

2016-11-04pinctrl: cherryview: Serialize register access in suspend/resumeMika Westerberg1-0/+10
If async suspend is enabled, the driver may access registers concurrently with another instance which may fail because of the bug in Cherryview GPIO hardware. Prevent this by taking the shared lock while accessing the hardware in suspend and resume hooks.

2016-11-04PCI: designware: Check for iATU unroll support after initializing hostNiklas Cassel1-2/+5
dw_pcie_iatu_unroll_enabled() reads a dbi_base register. Reading any dbi_base register before pp->ops->host_init has been called causes "imprecise external abort" on platforms like ARTPEC-6, where the PCIe module is disabled at boot and first enabled in pp->ops->host_init. Move dw_pcie_iatu_unroll_enabled() to dw_pcie_setup_rc(), since it is after pp->ops->host_init, but before pp->iatu_unroll_enabled is actually used.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v4.9 The most important fix in here is a change which removes the #error making the topology API unusable as-is since we have recently discovered some production uses on Chromebooks so need to acknowledge that what we've got there now is an ABI. There's also a very big batch of driver specific fixes here which have kept on being delayed due to more arriving so the update is another of these bigger than I would like ones. There is one especially big one in there, for the Qualcomm code which fixes simultaneous playback and capture which was broken during the merge window. The diff for that is large because it moves blocks of code to different functions but it's functionally fairly simple and if it breaks it should have been very obvious in testing.

2016-11-04i2c: core: fix NULL pointer dereference under race conditionVladimir Zapolskiy1-1/+1
Race condition between registering an I2C device driver and deregistering an I2C adapter device which is assumed to manage that I2C device may lead to a NULL pointer dereference due to the uninitialized list head of driver clients. The root cause of the issue is that the I2C bus may know about the registered device driver and thus it is matched by bus_for_each_drv(), but the list of clients is not initialized and commonly it is NULL, because I2C device drivers define struct i2c_driver as static and clients field is expected to be initialized by I2C core: i2c_register_driver() i2c_del_adapter() driver_register() ... bus_add_driver() ... ... bus_for_each_drv(..., __process_removed_adapter) ... i2c_do_del_adapter() ... list_for_each_entry_safe(..., &driver->clients, ...) INIT_LIST_HEAD(&driver->clients); To solve the problem it is sufficient to do clients list head initialization before calling driver_register(). The problem was found while using an I2C device driver with a sluggish registration routine on a bus provided by a physically detachable I2C master controller, but practically the oops may be reproduced under the race between arbitraty I2C device driver registration and managing I2C bus device removal e.g. by unbinding the latter over sysfs: % echo 21a4000.i2c > /sys/bus/platform/drivers/imx-i2c/unbind Unable to handle kernel NULL pointer dereference at virtual address 00000000 Internal error: Oops: 17 [#1] SMP ARM CPU: 2 PID: 533 Comm: sh Not tainted 4.9.0-rc3+ #61 Hardware name: Freescale i.MX6 Quad/DualLite (Device Tree) task: e5ada400 task.stack: e4936000 PC is at i2c_do_del_adapter+0x20/0xcc LR is at __process_removed_adapter+0x14/0x1c Flags: NzCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none Control: 10c5387d Table: 35bd004a DAC: 00000051 Process sh (pid: 533, stack limit = 0xe4936210) Stack: (0xe4937d28 to 0xe4938000) Backtrace: [<c0667be0>] (i2c_do_del_adapter) from [<c0667cc0>] (__process_removed_adapter+0x14/0x1c) [<c0667cac>] (__process_removed_adapter) from [<c0516998>] (bus_for_each_drv+0x6c/0xa0) [<c051692c>] (bus_for_each_drv) from [<c06685ec>] (i2c_del_adapter+0xbc/0x284) [<c0668530>] (i2c_del_adapter) from [<bf0110ec>] (i2c_imx_remove+0x44/0x164 [i2c_imx]) [<bf0110a8>] (i2c_imx_remove [i2c_imx]) from [<c051a838>] (platform_drv_remove+0x2c/0x44) [<c051a80c>] (platform_drv_remove) from [<c05183d8>] (__device_release_driver+0x90/0x12c) [<c0518348>] (__device_release_driver) from [<c051849c>] (device_release_driver+0x28/0x34) [<c0518474>] (device_release_driver) from [<c0517150>] (unbind_store+0x80/0x104) [<c05170d0>] (unbind_store) from [<c0516520>] (drv_attr_store+0x28/0x34) [<c05164f8>] (drv_attr_store) from [<c0298acc>] (sysfs_kf_write+0x50/0x54) [<c0298a7c>] (sysfs_kf_write) from [<c029801c>] (kernfs_fop_write+0x100/0x214) [<c0297f1c>] (kernfs_fop_write) from [<c0220130>] (__vfs_write+0x34/0x120) [<c02200fc>] (__vfs_write) from [<c0221088>] (vfs_write+0xa8/0x170) [<c0220fe0>] (vfs_write) from [<c0221e74>] (SyS_write+0x4c/0xa8) [<c0221e28>] (SyS_write) from [<c0108a20>] (ret_fast_syscall+0x0/0x1c) Signed-off-by: Vladimir Zapolskiy <[email protected]> Signed-off-by: Wolfram Sang <[email protected]> Cc: [email protected]

2016-11-04KVM: arm/arm64: vgic: Kick VCPUs when queueing already pending IRQsShih-Wei Li1-0/+12
In cases like IPI, we could be queueing an interrupt for a VCPU that is already running and is not about to exit, because the VCPU has entered the VM with the interrupt pending and would not trap on EOI'ing that interrupt. This could result to delays in interrupt deliveries or even loss of interrupts. To guarantee prompt interrupt injection, here we have to try to kick the VCPU.
