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 00/19] s390 spectre mititgation for 4.9

Greetings, this series is the backport of 19 upstream patches to add the current s390 spectre mitigation to kernel version 4.9.

[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.

[PATCH] arm64: defconfig: Enable CONFIG_PINCTRL_MT7622 by default

From: Sean Wang <sean.wang(a)mediatek.com> Recently kernelCI reported the board mt7622-rfb1 has a fail test with kernel: ERROR: did not start booting whose details could be seen at [1].

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.
