The problem is there is a race between a system call thread and the demultiplex thread and there may be a situation when the mid has been already processed before it is set as cancelled. Fix this by processing cancelled requests when mids are being destroyed which means that there is only one thread referencing a particular mid. Also set mids as cancelled unconditionally on their state.

[PATCH] serdev: Don't claim unsupported ACPI serial devices

by Punit Agrawal

Serdev sub-system claims all ACPI serial devices that are not already initialised. As a result, no device node is created for serial ports on certain boards such as the Apollo Lake based UP2. This has the unintended consequence of not being able to raise the login prompt via serial connection. Introduce a blacklist to reject ACPI serial devices that should not be claimed by serdev sub-system. Add the peripheral ids for Intel HS UART to the blacklist to bring back serial port on SoCs carrying them.

[V2] x86/tsc: Unset TSC_KNOWN_FREQ and TSC_RELIABLE flags on Intel Bay Trail SoC

by Vipul Kumar

From: Vipul Kumar <vipul_kumar(a)mentor.com> 'commit f3a02ecebed7 ("x86/tsc: Set TSC_KNOWN_FREQ and TSC_RELIABLE flags on Intel Atom SoCs")', causing time drift for Bay trail SoC. These flags are set for SoCs having cpuid_level 0x15 or more. Bay trail is having cpuid_level 0xb. So, unset both flags to make sure the clocksource calibration can be done.
