Nowadays, most Intel CPUs have "cpuid faulting" available which could trap
the execution of "cpuid" instruction when CPL>0 with GP fault. Thus,
"cpuid" instruction could trap to Xen hypervisor on the paravirtualized PV
guest on most servers today, except on old CPUs prior to 2011. On CPU after
2011, Xen will put "XenVMMXenVMM" on both HVM and PV guests, which could
have lscpu command erroneously classify the guest as type "full". The
current lscpu command, which is based on "cpuid" instruction, still assumes
that it will not cause the trap to Xen hypervisor on Xen PV guest and uses
/proc/xen to identify whether it's running on PV DomU or not. To identify
this kind of information under the help of
/sys/hypervisor/properties/features would be more accurate for the CPU
nowadays. The bit 5 (XENFEAT_mmu_pt_update_preserve_ad) of the features
will be set only when it's running on Xen PV domain. The combo of bit 3 and
8 (XENFEAT_supervisor_mode_kernel and XENFEAT_hvm_callback_vector) will be
set simultaneously only when it's running on Xen PVH domain.

On Power System, lspcu presently displays system model number instead of
processor model name. 'model' tag in cpuinfo contains system model name,
not processor model. Instead it uses 'cpu' tag for processor model name.
Also it uses 'revision' tag for processor model.
Fix lspcu so that it displays processor model number. Also display processor
model name.

lscpu currently prints information for CPUs configured in the system.
In case of KVM or other virtualized guest operating systems, this
refers to the virtual system, and bears no relation to the physical
topology of the system.
It would be useful if lscpu could also display the physical topology
info when available:
$ ./lscpu
Architecture: ppc64le
Byte Order: Little Endian
CPU(s): 16
On-line CPU(s) list: 0-15
Thread(s) per core: 1
Core(s) per socket: 1
Socket(s): 16
NUMA node(s): 1
Model: IBM pSeries (emulated by qemu)
Hypervisor vendor: KVM
Virtualization type: para
L1d cache: 64K
L1i cache: 32K
NUMA node0 CPU(s): 0-15
Physical sockets: 2 <<< New
Physical chips: 4 <<< New
Physical cores/chip: 4 <<< New
For now, physical topology information is available on platforms that
support the following RTAS (Real time abstraction service) call provided
by librtas:
rtas_get_sysparm(PROCESSOR_MODULE_INFO).
Currently this call is available to the PowerVM (pHYP) guests on PowerPC.
With a patch propoosed to PowerKVM, this RTAS call would also be available
to PowerKVM guests.

Intel compiler complains about printf style function calls with trivial
format string and no other arguments. Like this one:
../sys-utils/ipcrm.c(117): warning #2279: printf/scanf format not a string literal and no format arguments
err(EXIT_FAILURE, iskey ? _("key failed") : _("id failed"));
This adds a concise description of a tool to its usage text.

there is a theoretical buffer overflow possible in the hypervisor
parsing code of lscpu. It would require a proc entry to return way more
than expected so it's no high priority. But better be safe than sorry.
At first I thought about switching to fgets but there is another
code file that adds a format specifier. The diff is less intrusive
that way, too.

There are systems where the size file does not exist. Most badly even
lscpu -p would abort allthough it does not use the size:
$ lscpu -p
lscpu: error: cannot open

This patch does not abort in this case and prints "unknown size" in
human-readable case. For examle on this qemu pcc test machine:

Not all file systems support the d_type field and simply checking for
d_type == DT_DIR in is_node_dirent would cause the test suite to fail
if run on (for example) XFS.

The lscpu tool only shows the current and max CPU frequencies, however,
in many scenarios this is not enough. If there are energy saving situations
(like some CPUs being idle, or not fully used) the cpugov can lower this value.
