Also, do perhaps TX activity assume a wakeup for RX processing? Right now the
TX and RX threads are independent. So it would be nice to document how the

Hi,
as I was about to update kvm-kmod-2.6.38, I checked for KVM changes
since 2.6.38-rc7 which kvm-kmod is currently based on - none. That
surprised as the update queue is non-empty. Was something lost on the
way to stable, or are they on hold intentionally?

After updating when I start up no I am headless. How do I get headed

This is now stating qemu-kvm in headless mode. it tells me to use VNC

Enable virtio-rng, a virtio random number generator.
Guest kernel should be compiled with CONFIG_HW_RANDOM_VIRTIO.
Once enabled, A RNG device will be located at /dev/hwrng.

The address of the gpte was already calculated and stored in ptep_user
before entering cmpxchg_gpte().
This patch makes cmpxchg_gpte() to use that to make it clear that we
are using the same address during walk_addr_generic().

That will work, but does making rcu_note_context_switch() out of line
actually increase kernel size? The function is called in two places
currently, so by making it out of line we make two calling site smaller.
Will measure it next week.
