2020-12-12x86/kprobes: Fix optprobe to detect INT3 padding correctlyMasami Hiramatsu
Commit 7705dc855797 ("x86/vmlinux: Use INT3 instead of NOP for linker fill bytes") changed the padding bytes between functions from NOP to INT3. However, when optprobe decodes a target function it finds INT3 and gives up the jump optimization. Instead of giving up any INT3 detection, check whether the rest of the bytes to the end of the function are INT3. If all of them are INT3, those come from the linker. In that case, continue the optprobe jump optimization.

Commit 01bb86b380a3 ("driver core: Add fwnode_init()") was supposed to fix up all instances of fwnode creation to use fwnode_init(). But looks like this instance was missed.

2020-12-12irqchip/qcom-pdc: Fix phantom irq when changing between rising/fallingDouglas Anderson
We have a problem if we use gpio-keys and configure wakeups such that we only want one edge to wake us up. AKA: wakeup-event-action = <EV_ACT_DEASSERTED>; wakeup-source; Specifically we end up with a phantom interrupt that blocks suspend if the line was already high and we want wakeups on rising edges (AKA we want the GPIO to go low and then high again before we wake up). The opposite is also problematic. Specifically, here's what's happening today: 1. Normally, gpio-keys configures to look for both edges. Due to the current workaround introduced in commit c3c0c2e18d94 ("pinctrl: qcom: Handle broken/missing PDC dual edge IRQs on sc7180"), if the line was high we'd configure for falling edges. 2. At suspend time, we change to look for rising edges. 3. After qcom_pdc_gic_set_type() runs, we get a phantom interrupt. We can solve this by just clearing the phantom interrupt. NOTE: it is possible that this could cause problems for a client with very specific needs, but there's not much we can do with this hardware. As an example, let's say the interrupt signal is currently high and the client is looking for falling edges. The client now changes to look for rising edges. The client could possibly expect that if the line has a short pulse low (and back high) that it would always be detected. Specifically no matter when the pulse happened, it should either have tripped the (old) falling edge trigger or the (new) rising edge trigger. We will simply not trip it. We could narrow down the race a bit by polling our parent before changing types, but no matter what we do there will still be a period of time where we can't tell the difference between a real transition (or more than one transition) and the phantom.

2020-12-12ath11k: implement suspend for QCA6390 PCI devicesCarl Huang
Now that all the needed pieces are in place implement suspend support QCA6390 PCI devices. All other devices will return -EOPNOTSUPP during suspend. The suspend is implemented by switching the firmware to WoW mode during suspend, so the firmware will be running on low power mode while host is in suspend. At the moment we are not able to shutdown and fully power off the device due to bugs in MHI subsystem, so WoW mode is a workaround for the time being. During suspend we enable WoW mode, disable CE irq and DP irq, then put MHI to suspend state. During resume, driver resumes MHI firstly, then enables CE irq and dp IRQ, and sends WoW wakeup command to firmware.

2020-12-12ath11k: set credit_update flag for flow controlled ep onlyCarl Huang
Firmware will check all the pipes before entering WoW mode during suspend. If ATH11K_HTC_FLAG_NEED_CREDIT_UPDATE is set, firmware treats this pipe needed to return credit even though it's actually not required. If any pipe needs to return credit, the suspend_complete message doesn't send to host but is dropped. So host gets time out and WoW suspend failed.

2020-12-12ath10k: add atomic protection for device recoveryWen Gong
When it has more than one restart_work queued meanwhile, the 2nd restart_work is very easy to break the 1st restart work and lead recovery fail. Add a flag to allow only one restart work running untill device successfully recovered. It already has flag ATH10K_FLAG_CRASH_FLUSH, but it can not use this flag again, because it is clear in ath10k_core_start. The function ieee80211_reconfig(called by ieee80211_restart_work) of mac80211 do many things and drv_start(call to ath10k_core_start) is 1st thing, when drv_start complete, it does not mean restart complete. So it add new flag and clear it in ath10k_reconfig_complete, because it is the last thing called from drv_reconfig_complete of function ieee80211_reconfig, after it, the restart process finished.

2020-12-11tools/kvm_stat: Exempt time-based countersStefan Raspl
The new counters halt_poll_success_ns and halt_poll_fail_ns do not count events. Instead they provide a time, and mess up our statistics. Therefore, we should exclude them. Removal is currently implemented with an exempt list. If more counters like these appear, we can think about a more general rule like excluding all fields name "*_ns", in case that's a standing convention.

2020-12-11KVM: mmu: Fix SPTE encoding of MMIO generation upper halfMaciej S. Szmigiero
Commit cae7ed3c2cb0 ("KVM: x86: Refactor the MMIO SPTE generation handling") cleaned up the computation of MMIO generation SPTE masks, however it introduced a bug how the upper part was encoded: SPTE bits 52-61 were supposed to contain bits 10-19 of the current generation number, however a missing shift encoded bits 1-10 there instead (mostly duplicating the lower part of the encoded generation number that then consisted of bits 1-9). In the meantime, the upper part was shrunk by one bit and moved by subsequent commits to become an upper half of the encoded generation number (bits 9-17 of bits 0-17 encoded in a SPTE). In addition to the above, commit 56871d444bc4 ("KVM: x86: fix overlap between SPTE_MMIO_MASK and generation") has changed the SPTE bit range assigned to encode the generation number and the total number of bits encoded but did not update them in the comment attached to their defines, nor in the KVM MMU doc. Let's do it here, too, since it is too trivial thing to warrant a separate commit. Fixes: cae7ed3c2cb0 ("KVM: x86: Refactor the MMIO SPTE generation handling") Signed-off-by: Maciej S.
