[XenPPC] [PATCH][RFC] New command: xm pcpu-list

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi all,

I would push a new command "xm pcpu-list" that reports physical 
CPU configuration.
I suppose that Xen works on a machine where a lot of physical 
CPUs are installed.  It is useful for users to know the 
configuration of physical CPUs so that they can allocate VCPUs 
efficiently. This command offers the means for it.

I began this patch with ia64 machines.  It is just because I 
have one.

I would like to make this command work on x86 and powerpc 
machines.  Unfortunately, I don't have any with dual-core and 
multi-thread features.  I don't have much information on them 
either.  I would appreciate if you give any help to make the 
command work on x86 and powerpc.

Best regards,
 Kan
