Applied "ASoC: mediatek: preallocate pages use platform device" to the asoc tree

by Mark Brown

The patch ASoC: mediatek: preallocate pages use platform device has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

Cherry-pick "arm64: dts: rockchip: remove vdd_log from rk3399-puma" for 4.14.y?

by Jakob Unterwurzacher

Dear Greg, a fix for a voltage instability on our rk3399-puma board went into 4.15 (commit 87eba0716011, quoted below). As we have users who prefer to stay on longterm 4.14, would you consider cherry-picking the commit into 4.14.y? It applies cleanly and has no effect outside of our rk3399-puma board, where it fixes the instability. Thank you and best regards, Jakob > commit 87eba0716011e528f7841026f2cc65683219d0ad > Author: Klaus Goger <klaus.goger(a)theobroma-systems.com> > Date: Tue Dec 5 08:11:58 2017 +0100 > > arm64: dts: rockchip: remove vdd_log from rk3399-puma > > vdd_log has no consumer and therefore will not be set to a specific > voltage.

[PATCH] fsnotify: Fix fsnotify_mark_connector race

by Seyeong Kim

From: Robert Kolchmeyer <rkolchmeyer(a)google.com> BugLink: http://bugs.launchpad.net/bugs/1765564 fsnotify() acquires a reference to a fsnotify_mark_connector through the SRCU-protected pointer to_tell->i_fsnotify_marks. However, it appears that no precautions are taken in fsnotify_put_mark() to ensure that fsnotify() drops its reference to this fsnotify_mark_connector before assigning a value to its 'destroy_next' field. This can result in fsnotify_put_mark() assigning a value to a connector's 'destroy_next' field right before fsnotify() tries to traverse the linked list referenced by the connector's 'list' field. Since these two fields are members of the same union, this behavior results in a kernel panic. This issue is resolved by moving the connector's 'destroy_next' field into the object pointer union. This should work since the object pointer access is protected by both a spinlock and the value of the 'flags' field, and the 'flags' field is cleared while holding the spinlock in fsnotify_put_mark() before 'destroy_next' is updated. It shouldn't be possible for another thread to accidentally read from the object pointer after the 'destroy_next' field is updated. The offending behavior here is extremely unlikely; since fsnotify_put_mark() removes references to a connector (specifically, it ensures that the connector is unreachable from the inode it was formerly attached to) before updating its 'destroy_next' field, a sizeable chunk of code in fsnotify_put_mark() has to execute in the short window between when fsnotify() acquires the connector reference and saves the value of its 'list' field. On the HEAD kernel, I've only been able to reproduce this by inserting a udelay(1) in fsnotify(). However, I've been able to reproduce this issue without inserting a udelay(1) anywhere on older unmodified release kernels, so I believe it's worth fixing at HEAD.

Please apply commit 821cdad5c46c to v4.9.y

by Sinan Kaya

Hi Greg, Upstream commit 821cdad5c46c ("PCI: Wait up to 60 seconds for device to become ready after FLR") fixes a virtualization issue for Intel 750 NVMe drive and potentially other PCIe devices taking longer to recover from functional resets. problem description below from the commit: 'Sporadic reset issues have been observed with an Intel 750 NVMe drive while assigning the physical function to the guest machine. The sequence of events observed is as follows: - perform a Function Level Reset (FLR) - sleep up to 1000ms total - read ~0 from PCI_COMMAND (CRS completion for config read) - warn that the device didn't return from FLR - touch the device before it's ready - device drops config writes when we restore register settings (there's no mechanism for software to learn about CRS completions for writes) - incomplete register restore leaves device in inconsistent state - device probe fails because device is in inconsistent state After reset, an endpoint may respond to config requests with Configuration Request Retry Status (CRS) to indicate that it is not ready to accept new requests. See PCIe r3.1, sec 2.3.1 and 6.6.2.' Please apply commit 821cdad5c46c to fix the resulting regression.

[PATCH] mm: sections are not offlined during memory hotremove

by Pavel Tatashin

Memory hotplug, and hotremove operate with per-block granularity. If machine has large amount of memory (more than 64G), the size of memory block can span multiple sections. By mistake, during hotremove we set only the first section to offline state. The bug was discovered because kernel selftest started to fail: https://lkml.kernel.org/r/20180423011247.GK5563@yexl-desktop After commit, "mm/memory_hotplug: optimize probe routine". But, the bug is older than this commit. In this optimization we also added a check for sections to be in a proper state during hotplug operation.

[PATCH v2][for 4.17-rc3] cpufreq / CPPC: Set platform specific transition_delay_us

by Prashanth Prakash

Add support to specify platform specific transition_delay_us instead of using the transition delay derived from PCC. With commit "3d41386d556d: cpufreq: CPPC: Use transition_delay_us depending transition_latency" we are setting transition_delay_us directly and not applying the LATENCY_MULTIPLIER. With this on Qualcomm Centriq we can end up with a very high rate of frequency change requests when using schedutil governor (default rate_limit_us=10 compared to an earlier value of 10000). The PCC subspace describes the rate at which the platform can accept commands on the CPPC's PCC channel. This includes read and write command on the PCC channel that can be used for reasons other than frequency transitions. Moreover the same PCC subspace can be used by multiple freq domains and deriving transition_delay_us from it as we do now can be sub-optimal. Moreover if a platform does not use PCC for desired_perf register then there is no way to compute the transition latency or the delay_us. CPPC does not have a standard defined mechanism to get the transition rate or the latency at the moment. Given the above limitations, it is simpler to have a platform specific transition_delay_us and rely on PCC derived value only if a platform specific value is not available.

[PATCH v2 1/2] pinctrl/samsung: Correct EINTG banks order

by Paweł Chmiel

All banks with GPIO interrupts should be at beginning of bank array and without any other types of banks between them. This order is expected by exynos_eint_gpio_irq, when doing interrupt group to bank translation. Otherwise, kernel NULL pointer dereference would happen when trying to handle interrupt, due to wrong bank being looked up. Observed on s5pv210, when trying to handle gpj0 interrupt, where kernel was mapping it to gpi bank.

[PATCH] libata: Apply NOLPM quirk for SanDisk SD7UB3Q*G1001 SSDs

by Hans de Goede

Richard Jones has reported that using med_power_with_dipm on a T450s with a Sandisk SD7UB3Q256G1001 SSD (firmware version X2180501) is causing the machine to hang. Switching the LPM to max_performance fixes this, so it seems that this Sandisk SSD does not handle LPM well. Note in the past there have been bug-reports about the following Sandisk models not working with min_power, so we may need to extend the quirk list in the future: name - firmware Sandisk SD6SB2M512G1022I - X210400 Sandisk SD6PP4M-256G-1006 - A200906 Cc: stable(a)vger.kernel.org Cc: Richard W.M.

console: Drop added "static" for newport_con

by Dmitry Shmidt

Please add this patch to stable 4.14 commit f54450ad1942287cc76b38021c0441fc4901d2de Author: Kees Cook <keescook(a)chromium.org> Date: Tue Feb 27 13:11:21 2018 -0800 console: Drop added "static" for newport_con Commit 4fe505119778 ("console: Expand dummy functions for CFI") accidentally added "static" to newport_con instance of struct consw, while trying to normalize the declarations. This, however, needed to stay non-static as it has an extern.

Please apply commit 028daf801173 to v4.14.y

by Sinan Kaya

Hi Greg, Upstream commit 028daf801173 ("i40e: Fix attach VF to VM issue") fixes a virtualization issue for i40e based adapters. problem description below from the commit: 'Fix for "Resource temporarily unavailable" problem when virsh is trying to attach a device to VM. When the VF driver is loaded on host and virsh is trying to attach it to the VM and set a MAC address, it ends with a race condition between i40e_reset_vf and i40e_ndo_set_vf_mac functions. The bug is fixed by adding polling in i40e_ndo_set_vf_mac function For when the VF is in Reset mode.' Please apply commit 028daf801173 to fix the resulting regression. Thanks, Sinan -- Sinan Kaya Qualcomm Datacenter Technologies, Inc. as an affiliate of Qualcomm Technologies, Inc.

patch "USB: serial: ftdi_sio: use jtag quirk for Arrow USB Blaster" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: serial: ftdi_sio: use jtag quirk for Arrow USB Blaster to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 470b5d6f0cf4674be2d1ec94e54283a1770b6a1a Mon Sep 17 00:00:00 2001 From: Vasyl Vavrychuk <vvavrychuk(a)gmail.com> Date: Wed, 11 Apr 2018 17:05:13 +0300 Subject: USB: serial: ftdi_sio: use jtag quirk for Arrow USB Blaster Arrow USB Blaster integrated on MAX1000 board uses the same vendor ID (0x0403) and product ID (0x6010) as the "original" FTDI device.
