/proc/stats shows invalid gtime when the thread is running in guest.
When vtime accounting is not enabled, we cannot get a valid delta.
The delta is calculated now - tsk->vtime_snap, but tsk->vtime_snap
is only updated when vtime accounting is enabled.

There is an extra cost in task_cputime() and task_cputime_scaled() when
nohz_full is not activated. This patch removes that cost. When vtime
accounting is not enabled, we don't need to get deltas of utime and stime
with seqlock.
This patch adds a shortcut route if vtime a

This series is only dealing with vmstat changes. Do I get an ack here?

This leaves vring_new_virtqueue alone for compatbility, but it
adds two new improved APIs:

Once virtio starts using the DMA API, we won't be able to safely DMA
from the stack. virtio-net does a couple of config DMA requests
from small stack buffers -- switch to using dynamically-allocated
memory.
This should have no effect on any performance-critical code p
This fixes virtio-pci on platforms and busses that have IOMMUs. This
will break the experimental QEMU Q35 IOMMU support until QEMU is
fixed. In exchange, it fixes physical virtio hardware as well as
virtio-pci running under Xen.
We should clean up the virtqueue API to do its own allocation and

virtio_ring currently sends the device (usually a hypervisor)
physical addresses of its I/O buffers. This is okay when DMA
addresses and physical addresses are the same thing, but this isn't
always the case. For example, this never works on Xen guests, and
it is likely to fail if a physical "virt

This switches virtio to use the DMA API unconditionally. I'm sure
it breaks things, but it seems to work on x86 using virtio-pci, with

This appears to work on native and Xen x86_64 using both modern and

Depending on the version of hardware or its properties, which are only
known at runtime, various properties of the OPP can change. For example,
an OPP with frequency 1.2 GHz, may have different voltage/current
requirements based on the version of the hardware it is running on.
Similarly, it may or
