KVM calls kvm_pmu_set_counter_event_type() when PMCCFILTR is configured.
But this function can't deals with PMCCFILTR correctly because the evtCount

Going through the first VCPU is wrong if you follow a KVM_SET_CLOCK with
a KVM_GET_CLOCK immediately after, without letting the VCPU run and

- drop dtsi file since Model A+ and Zero aren't identical

ARM: bcm2835: Fix name
There are some differences between the schematics and the official firmware
DTS [1]. So based on these additional information the following has been
changed:
* use consistent "CAM_GPIO1" for camera LED
* use consistent "CAM_GPIO0" for camera shutdown
* add "USB_LIMIT" for USB current limit (0=600m
This adds the GPIO names for the Raspberry Pi Zero. The GPIO lines
of the RPi Zero are almost identical to the Model A+ except:
* GPIO 35, 38, 40 and 45 are not connected
* Status LED is active low

Hi Yishai,
Johannes has been working on an mlx4 initialization problem on an
IBM x3850 X6. The underlying problem is a PCI core issue -- we're
setting RCB in the Mellanox device, which means it thinks it can

can't handle them. Tha

This patch enables perf core PMU support for AMD family17h processors.
In family17h, there is no PMC-event constraint. All events, irrespective
of the type, can be measured using any of the performance counters.
