[PATCH 4.14] swiotlb: clean up reporting

by Ben Hutchings

commit 7d63fb3af87aa67aa7d24466e792f9d7c57d8e79 upstream. This removes needless use of '%p', and refactors the printk calls to use pr_*() helpers instead.

[PATCH] x86/resctrl: Ensure usage of CPUs are locked while needed

by Reinette Chatre

The user triggers the creation of a pseudo-locked region when writing the requested schemata to the schemata resctrl file. The pseudo-locking of a region is required to be done on a CPU that is associated with the cache on which the pseudo-locked region will reside. In order to run the locking code on a specific CPU the needed CPU has to be selected and ensured to remain online during the entire locking sequence. At this time the cpu_hotplug_lock is not taken during the pseudo-lock region creation and it is thus possible for a CPU to be selected to run the pseudo-locking code and then that CPU to go offline before the thread is able to run on it. Fix this by ensuring that the cpu_hotplug_lock is taken while the CPU on which code has to run needs to be controlled. Since the cpu_hotplug_lock is always taken before rdtgroup_mutex the lock order is maintained.

[PATCH 2/2] tracing: Fix memory leak in set_trigger_filter()

by Steven Rostedt

From: "Steven Rostedt (VMware)" <rostedt(a)goodmis.org> When create_event_filter() fails in set_trigger_filter(), the filter may still be allocated and needs to be freed. The caller expects the data->filter to be updated with the new filter, even if the new filter failed (we could add an error message by setting set_str parameter of create_event_filter(), but that's another update). But because the error would just exit, filter was left hanging and nothing could free it. Found by kmemleak detector.

[PATCH 1/1] usb: dwc2: disable power_down on Amlogic devices

by Martin Blumenstingl

Disable power_down by setting the parameter to DWC2_POWER_DOWN_PARAM_NONE. This fixes a problem on various Amlogic Meson SoCs where USB devices are only recognized when plugged in before booting Linux. A hot-plugged USB device was not detected even though the device got power (my USB thumb drive for example has an LED which lit up). A similar fix was implemented for Rockchip SoCs in commit c216765d3a1def ("usb: dwc2: disable power_down on rockchip devices"). That commit suggests that a change in the dwc2 driver is the cause because the default value for the "hibernate" parameter (which then got renamed to "power_down" to support other modes) was changed in the v4.17 merge window with: commit 6d23ee9caa6790 ("Merge tag 'usb-for-v4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-testing").

[PATCH] ARC: [zebu] Remove CONFIG_INITRAMFS_SOURCE from defconfigs

by Alexey Brodkin

Zebu boards were added in v4.9 and then renamed to "haps" in v4.10. Thus backporting commit 64234961c145 (ARC: configs: Remove CONFIG_INITRAMFS_SOURCE from defconfigs) we missed "zebu" defconfigs in v4.9. Note this is only applicable to "linux-4.9.y"! Spotted by KerneCI, see [1].
