[PATCH 3/4] tty: serial: 8250_mtk: use pm_runtime callbacks for enabling

The pm_runtime callbacks already enable and disable the device. Use them in probe() and remove() instead of duplicating the code. This allows us to concentrate more code for enabling/disabling the UART in a single place. Signed-off-by: Sascha Hauer --- drivers/tty/serial/8250/8250_mtk.c | 69 +++

[PATCH 1/2] brcmfmac: prohibit ACPI power management for brcmfmac driver

ACPI will manage WiFi chip's power state during suspend/resume process on some tablet platforms(such as ASUS T100TA). This is not supported by brcmfmac driver now, and the context of WiFi chip will be damaged after resume. This patch disconnects the relationship between WiFi chip and it's ACPI comp

[PATCH 3/3 v2] md/raid5: per hash value and exclusive wait_for_stripe

I noticed heavy spin lock contention at get_active_stripe() with fsmark multiple thread write workloads. Here is how this hot contention comes from. We have limited stripes, and it's a multiple thread write workload. Hence, those stripes will be taken soon, which puts later processes to sleep for

[PATCH 1/3] wait: introduce wait_event_cmd_exclusive

It's just a variant of wait_event_cmd, with exclusive flag being set. For cases like RAID5, which puts many processes to sleep until 1/4 resources are free, a wake_up wakes up all processes to run, but there is one process being able to get the resource as it's protected by a spin lock. That ends

I noticed heavy spin lock contention at get_active_stripe(), introduced at being wake up stage, where a bunch of processes try to re-hold the spin lock again. After giving some thoughts on this issue, I found the lock could be relieved(and even avoided) if we turn the wait_for_stripe to per waitqu
