2017-03-02ath10k: search SMBIOS for OEM board file extensionWaldemar Rymarkiewicz
Board Data File (BDF) is loaded upon driver boot-up procedure. The right board data file is identified, among others, by device and sybsystem ids. The problem, however, can occur when the (default) board data file cannot fulfill with the vendor requirements and it is necessary to use a different board data file. To solve the issue QCA uses SMBIOS type 0xF8 to store Board Data File Name Extension to specify the extension/variant name. The driver will take the extension suffix into consideration and will load the right (non-default) board data file if necessary. If it is unnecessary to use extension board data file, please leave the SMBIOS field blank and default configuration will be used. Example: If a default board data file for a specific board is identified by a string "bus=pci,vendor=168c,device=003e,subsystem-vendor=1028, subsystem-device=0310" then the OEM specific data file, if used, could be identified by variant suffix: "bus=pci,vendor=168c,device=003e,subsystem-vendor=1028, subsystem-device=0310,variant=DE_1AB" If board data file name extension is set but board-2.bin does not contain board data file for the variant, the driver will fallback to the default board data file not to break backward compatibility. This was first applied in commit f2593cb1b291 ("ath10k: Search SMBIOS for OEM board file extension") but later reverted in commit 005c3490e9db ("Revert "ath10k: Search SMBIOS for OEM board file extension"". This patch is now otherwise the same as commit f2593cb1b291 except the regression fixed.

2017-03-02x86/hpet: Prevent might sleep splat on resumeThomas Gleixner
Sergey reported a might sleep warning triggered from the hpet resume path. It's caused by the call to disable_irq() from interrupt disabled context. The problem with the low level resume code is that it is not accounted as a special system_state like we do during the boot process. Calling the same code during system boot would not trigger the warning. That's inconsistent at best. In this particular case it's trivial to replace the disable_irq() with disable_hardirq() because this particular code path is solely used from system resume and the involved hpet interrupts can never be force threaded.

2017-03-02sched/clock, x86/tsc: Rework the x86 'unstable' sched_clock() interfacePeter Zijlstra
Wanpeng Li reported that since the following commit: acb04058de49 ("sched/clock: Fix hotplug crash") ... KVM always runs with unstable sched-clock even though KVM's kvm_clock _is_ stable. The problem is that we've tied clear_sched_clock_stable() to the TSC state, and overlooked that sched_clock() is a paravirt function. Solve this by doing two things: - tie the sched_clock() stable state more clearly to the TSC stable state for the normal (!paravirt) case. - only call clear_sched_clock_stable() when we mark TSC unstable when we use native_sched_clock(). The first means we can actually run with stable sched_clock in more situations then before, which is good. And since commit: 12907fbb1a69 ("sched/clock, clocksource: Add optional cs::mark_unstable() method") ... this should be reliable. Since any detection of TSC fail now results in marking the TSC unstable.

Kitsunyan reported desktop latency issues on his Celeron 887 because of commit: 1b568f0aabf2 ("sched/core: Optimize SCHED_SMT") ... even though his CPU doesn't do SMT. The effect of running the SMT code on a !SMT part is basically a more aggressive select_idle_cpu(). Removing the avg condition fixed things for him. I also know FB likes this test gone, even though other workloads like having it. For now, take it out by default, until we get a better idea.
