The vcpu_id for legacy PVH mode can be set from the output of cpuid,
so there's no need to have a special function to set it.
Also note that xenpv_set_ids should have been executed only for PV
guests, but was executed for all guests types and vcpu_id was later
fixed up for HVM guests.

When running as a specific type of Xen guest the hypervisor won't

cpuid = 0

newvers.sh supports two modes for reproducible builds:
-r Reproducible build. Do not embed directory names, user
names, time stamps or other dynamic information into
the output file. This is intended to allow two builds
done at different times and even by different people on
different hosts to produce identical output.
-R Reproducible build if the tree represents an unmodified
checkout from a version control system. Metadata is
included if the tree is modified.
Switch to the second mode when reproducible builds are enabled.
The value of a reproducible build is much less when building from an
uncontrolled, modified src tree, and -R likely provides the best
compromise in allowing the REPRODUCIBLE_BUILD knob to be enabled by
default for the release.

The receive side scaling stride parameter is a value which define the interval
between active receive side queues. The traffic for the inactive queues is
redirected to the nearest active queue by use of modulus. The default value
of this parameter is one, which means all receive side queues are used.
The point of this feature is to redirect more traffic to fewer receive side
queues in order to take more advantage of sorted large receive offload,
sorted LRO. The sorted LRO works better when more packets are accumulated
per service interval.
