KVM: Pass MMU notifier range flags to kvm_unmap_hva_range()

2020-08-26T09:42:24+00:00

commit fdfe7cbd58806522e799e2a50a15aee7f2cbb7b6 upstream. The 'flags' field of 'struct mmu_notifier_range' is used to indicate whether invalidate_range_{start,end}() are permitted to block. In the case of kvm_mmu_notifier_invalidate_range_start(), this field is not forwarded on to the architecture-specific implementation of kvm_unmap_hva_range() and therefore the backend cannot sensibly decide whether or not to block. Add an extra 'flags' parameter to kvm_unmap_hva_range() so that architectures are aware as to whether or not they are permitted to block.

arm64: perf: Correct the event index in sysfs

2020-08-21T11:07:22+00:00

commit 539707caa1a89ee4efc57b4e4231c20c46575ccc upstream. When PMU event ID is equal or greater than 0x4000, it will be reduced by 0x4000 and it is not the raw number in the sysfs. Let's correct it and obtain the raw event ID. Before this patch: cat /sys/bus/event_source/devices/armv8_pmuv3_0/events/sample_feed event=0x001 After this patch: cat /sys/bus/event_source/devices/armv8_pmuv3_0/events/sample_feed event=0x4001 Signed-off-by: Shaokun Zhang Cc: Will Deacon Cc: Mark Rutland Cc: Link: https://lore.kernel.org/r/1592487344-30555-3-git-send-email-zhangshaokun@hisilicon.com [will: fixed formatting of 'if' condition] Signed-off-by: Will Deacon Signed-off-by: Greg Kroah-Hartman

arm64: dts: sun50i-pinephone: dldo4 must not be >= 1.8V

2020-08-19T06:23:28+00:00

[ Upstream commit 86be5c789690eb08656b08c072c50a7b02bf41f1 ] Some outputs from the RTL8723CS are connected to the PL port (BT_WAKE_AP), which runs at 1.8V. When BT_WAKE_AP is high, the PL pin this signal is connected to is overdriven, and the whole PL port's voltage rises somewhat. This results in changing voltage on the R_PWM pin (PL10), which is the cause for backlight flickering very noticeably when typing on a Bluetooth keyboard, because backlight intensity is highly sensitive to the voltage of the R_PWM pin. Limit the maximum WiFi/BT I/O voltage to 1.8V to avoid overdriving the PL port pins via BT and WiFi IO port signals. WiFi and BT functionality is unaffected by this change. This completely stops the backlight flicker when using bluetooth.

arm64: dts: qcom: msm8916: Replace invalid bias-pull-none property

2020-08-19T06:23:26+00:00

[ Upstream commit 1b6a1a162defe649c5599d661b58ac64bb6f31b6 ] msm8916-pins.dtsi specifies "bias-pull-none" for most of the audio pin configurations. This was likely copied from the qcom kernel fork where the same property was used for these audio pins. However, "bias-pull-none" actually does not exist at all - not in mainline and not in downstream. I can only guess that the original intention was to configure "no pull", i.e. bias-disable. Change it to that instead.

arm64: dts: rockchip: fix rk3399-puma gmac reset gpio

[ Upstream commit 8a445086f8af0b7b9bd8d1901d6f306bb154f70d ] The puma gmac node currently uses opposite active-values for the gmac phy reset pin. The gpio-declaration uses active-high while the separate snps,reset-active-low property marks the pin as active low.
