If a guest sets an interrupt to active, but that interrupt is already flushed into a list register on a running VCPU, then that VCPU will write the active state back into the struct vgic_irq upon returning from the guest and syncing its state. This is a non-benign race, because the guest can observe that an interrupt is not active, and it can have a reasonable expectations that other VCPUs will not ack any IRQs, and then set the state to active, and expect it to stay that way. Currently we are not honoring this case. Thefore, change both the SACTIVE and CACTIVE mmio handlers to stop the world, change the irq state, potentially queue the irq if we're setting it to active, and then continue. We take this chance to slightly optimize these functions by not stopping the world when touching private interrupts where there is inherently no possible race.

Currently the only user of kvm_io_bus for ARM is the VGIC, which did this copying itself, so this was not causing issues so far. But with the upcoming new vgic implementation we need this done properly. Update the kvm_handle_mmio_return description and cleanup the code to only perform a single copying when needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are about to modify the VGIC to allocate all data structures dynamically and store mapped IRQ information on a per-IRQ struct, which is indeed allocated dynamically at init time. Therefore, we cannot record the mapped IRQ info from the timer at timer reset time like it's done now, because VCPU reset happens before timer init. A possible later time to do this is on the first run of a per VCPU, it just requires us to move the enable state to be a per-VCPU state and do the lookup of the physical IRQ number when we are about to run the VCPU.

This way we keep the perf_sample->ip_callchain->nr meaning, that is the number of entries, be it real addresses or PERF_CONTEXT_ entries, while honouring the max_stack knobs, i.e. the end result will be max_stack entries if we have at least that many entries in a given stack trace.

This is influenced by the DRM atomic API that was introduced a while back, though it is obviously a lot simpler. The fundamental idea remains the same, though: drivers provide a single callback to implement the atomic configuration of a PWM channel. As a side-effect the PWM subsystem gains the ability for initial state retrieval, so that the logical state mirrors that of the hardware. Many use-cases don't care about this, but for others it is essential. These new features require changes in all users, which these patches take care of. The core is transitioned to use the atomic callback if available and provides a fallback mechanism for other drivers. Changes to transition users and drivers to the atomic API are postponed to v4.8" * tag 'pwm/for-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm: (30 commits) pwm: Add information about polarity, duty cycle and period to debugfs pwm: Switch to the atomic API pwm: Update documentation pwm: Add core infrastructure to allow atomic updates pwm: Add hardware readout infrastructure pwm: Move the enabled/disabled info into pwm_state pwm: Introduce the pwm_state concept pwm: Keep PWM state in sync with hardware state ARM: Explicitly apply PWM config extracted from pwm_args drm: i915: Explicitly apply PWM config extracted from pwm_args input: misc: pwm-beeper: Explicitly apply PWM config extracted from pwm_args input: misc: max8997: Explicitly apply PWM config extracted from pwm_args backlight: lm3630a: explicitly apply PWM config extracted from pwm_args backlight: lp855x: Explicitly apply PWM config extracted from pwm_args backlight: lp8788: Explicitly apply PWM config extracted from pwm_args backlight: pwm_bl: Use pwm_get_args() where appropriate fbdev: ssd1307fb: Use pwm_get_args() where appropriate regulator: pwm: Use pwm_get_args() where appropriate leds: pwm: Use pwm_get_args() where appropriate input: misc: max77693: Use pwm_get_args() where appropriate ...
