Using the CPU number to compare with an index into an array containing
only a subset of CPUs isn't valid. And indicator isn't necessary here
at all since the CPU number being dealt with gets printed right before
this line.

{acpi,powernow}_cpufreq_cpu_init() generally don't run on the CPU the
policy they deal with is related to, hence using cpuid() directly
works only as long as all CPUs in the system are identical (which
admittedly is commonly the case).
Further add a per-policy flag indicating the availability of
APERF/MPERF MSRs, so that globally setting the .getavg accessor won't
be a problem on heterogeneous configurations.

On large systems, dumping state may cause time management to get
stalled for so long a period that it wouldn't recover. Therefore alter
the state dumping logic to alternatively block each CPU as it prints
rather than one CPU for a very long time (using the alternative key
handling toggle introduced with an earlier patch).
Further, instead of using on_selected_cpus(), which is unsafe when
the dumping happens from a hardware interrupt, introduce and use a
dedicated IPI sending function (which each architecture can implement
to its liking)
Finally, don't print useless data (e.g. the hypervisor context of the
interrupt that is used for triggering the printing, but isn't part of
the context that's actually interesting).

This patch makes sure that if the domain creation fails for any
reason, no zombie domains are left around.

The CPUID4 emulation code for AMD CPUs in intel_cacheinfo.c won't be
executed. This emulation code was from upstream kernel, where CPUID4
is used for cache information report in sysfs. But in Xen, this code
path won't be executed on AMD CPUs. init_amd() uses
display_cacheinfo() to find out CPU cache size instead.

Just like for other global VMX controls, the maximum super page level
used must be globally consistent (and not change post-init).
Additionally, the original patch yet again introduced a message
printed on each CPU, which this patch moves to a place where it gets
issued just once.
