In order to get such a preempt-rt Linux kerne, we grab -rt patch via
https://www.kernel.org/pub/linux/kernel/projects/rt/. So far we just enable it
over 4.14.x.

This should make debugging a lot easier. Note, 991f8f1c6eb6
("hyper-v: trace channel events"), patch 18, required some
minor modifications from upstream as another patch was not easy
to cherry-pick.

Drop the hack for the microcode division by 0 on GCP as
a proper fix is in upstream as:

These kernels have significant changes/addition for Spectre
mitigation as well as the usual other set of fixes.

The YAMLs in ./test/hack enumerated the images to pull with
content trust. All images in the 'linuxkit' org should
now have trust enabled.

The CONFIG_BPF_JIT_ALWAYS_ON option has now been back-ported
to 4.4.115 as well. Enable it.

This adds a patch to avoid a division by zero panic for 4.4.x
and 4.9.x kernels on single vCPU machine types on Google Cloud.
4.14.x and 4.15.x kernels seem to work fine.

This option is not enabled by default, but disables the
BPF interpreter which can be used to inject speculative
execution into the kernel. Enabled it as it seems
like a good security measure.

The 4.14 and 4.9 kernels have a significant number of
fixes to eBPF and also a fix for kernel level sockets
and namespace removals, ie fixes some aspects of

Upstream qemu supports accelerators other than kvm. Allow the user
to choose. On Linux we still default to 'lvm' if available. On
macOS we try the new 'hvf' accelerator, if available.
Disable acceleration if the host arch does not match requested
qemu arch.
Also change the LINUXKIT_QEMU_KVM env var to LINUXKIT_QEMU_ACCEL
and use the functions in utils.go for env var overrides.

It still defaults to whatever is in your PATH but it's
useful to override when experimenting with different
qemu builds.
