I hope the "Fixes" tag will work, but yeah, my bad, cc:stable is definitely a good idea here. Added stable@ to cc. Thanks!

[PATCH 1/2] i2c: i801: Fix runtime PM

by Jarkko Nikula

Commit 9c8088c7988 ("i2c: i801: Don't restore config registers on runtime PM") nullified the runtime PM suspend/resume callback pointers while keeping the runtime PM enabled. This causes that device stays in D0 power state and sysfs /sys/bus/pci/devices/.../power/runtime_status shows "error" when runtime PM framework attempts to autosuspend the device. This is due PCI bus runtime PM which checks for driver runtime PM callbacks and returns with -ENOSYS if they are not set. Fix this by having a shared dummy runtime PM callback that returns with success.

[PATCH] pinctrl: cherryview: Add quirk with custom translation of ACPI GPIO numbers

by Michal Stanek

Dropping custom Linux GPIO translation caused some Intel_Strago based Chromebooks with old firmware to detect GPIOs incorrectly. Add quirk which restores some code removed by commit 03c4749dd6c7ff94 ("gpio / ACPI: Drop unnecessary ACPI GPIO to Linux GPIO translation").

[PATCH] ARM: tegra: Fix restoration of PLLM when exiting suspend

by Jon Hunter

The suspend entry and exit code for 32-bit Tegra devices assumes that the PLLM (which is used to provide the clock for external memory) is always enabled on entry to suspend. Hence, the current code always disables the PLLM on entry to suspend and re-enables the PLLM on exit from suspend. Since the introduction of the Tegra124 EMC driver by commit 73a7f0a90641 ("memory: tegra: Add EMC (external memory controller) driver"), which is used to scale the EMC frequency, PLLM may not be the current clock source for the EMC on entry to suspend and hence may not be enabled. Always enabling the PLLM on exit from suspend can cause the actual status on the PLL to be different from that reported by the common clock framework. On kernels prior to v4.5, the code to set the rate of the PLLM had a test to verify if the PLL was enabled and if the PLL was enabled, setting the rate would fail. Since commit 267b62a96951 ("clk: tegra: pll: Update PLLM handling") the test to see if PLLM is enabled was removed. With these earlier kernels, if the PLLM is disabled on entering suspend and the EMC driver attempts to set the parent of the EMC clock to the PLLM on exiting suspend, then the set rate for the PLLM will fail and in turn cause the resume to fail. We should not be re-enabling the PLLM on resume from suspend unless it was enabled on entry to suspend. Therefore, fix this by saving the state of PLLM on entry to suspend and only re-enable it, if it was already enabled.

[PATCH 03/12] lpfc: Fix broken Credit Recovery after driver load

by James Smart

When driver is set to enable bb credit recovery, the switch displayed the setting as inactive. If the link bounces, it switches to Active. During link up processing, the driver currently does a MBX_READ_SPARAM followed by a MBX_CONFIG_LINK. These mbox commands are queued to be executed, one at a time and the completion is processed by the worker thread. Since the MBX_READ_SPARAM is done BEFORE the MBX_CONFIG_LINK, the BB_SC_N bit is never set the the returned values. BB Credit recovery status only gets set after the driver requests the feature in CONFIG_LINK, which is done after the link up. Thus the ordering of READ_SPARAM needs to follow the CONFIG_LINK. Fix by reordering so that READ_SPARAM is done after CONFIG_LINK. Added a HBA_DEFER_FLOGI flag so that any FLOGI handling waits until after the READ_SPARAM is done so that the proper BB credit value is set in the FLOGI payload.

[PATCH 1/3] drm/atomic: Take the atomic toys away from X

by Daniel Vetter

The -modesetting ddx has a totally broken idea of how atomic works: - doesn't disable old connectors, assuming they get auto-disable like with the legacy setcrtc - assumes ASYNC_FLIP is wired through for the atomic ioctl - not a single call to TEST_ONLY Iow the implementation is a 1:1 translation of legacy ioctls to atomic, which is a) broken b) pointless. We already have bugs in both i915 and amdgpu-DC where this prevents us from enabling neat features. If anyone ever cares about atomic in X we can easily add a new atomic level (req->value == 2) for X to get back the shiny toys. Since these broken versions of -modesetting have been shipping, there's really no other way to get out of this bind.

[PATCH 01/12] aio: fix async fsync creds

by Miklos Szeredi

Avi Kivity reports that on fuse filesystems running in a user namespace asyncronous fsync fails with EOVERFLOW. The reason is that f_ops->fsync() is called with the creds of the kthread performing aio work instead of the creds of the process originally submitting IOCB_CMD_FSYNC. Fuse sends the creds of the caller in the request header and it needs to translate the uid and gid into the server's user namespace. Since the kthread is running in init_user_ns, the translation will fail and the operation returns an error. It can be argued that fsync doesn't actually need any creds, but just zeroing out those fields in the header (as with requests that currently don't take creds) is a backward compatibility risk. Instead of working around this issue in fuse, solve the core of the problem by calling the filesystem with the proper creds.
