Xen devel - Apr 2010 - [PATCH] Tools: add online/offline hotplug user interfaces

Hi, all

This patch is for exporting cpu on/offline and memory on/offline hotplug
interfaces,
so that users can do those (memory/cpu) hotplug actions with following command
line:

usage: xen-hptool <command> [args]
    xen-hptool command list:\n\n
    cpu-online    <cpuid>    online CPU <cpuid>
    cpu-offline   <cpuid>    offline CPU <cpuid>
    mem-online    <mfn>      online MEMORY <mfn>
    mem-offline   <mfn>      offline MEMORY <mfn>
    mem-status    <mfn>      query Memory status<mfn>

When mcelog do user-level predictive recovery actions, this tool interface might
be called by mcelog
recovery action scripts(mem page online/offline, eg). That''s why I want
to push this tool firstly.

Thanks& Regards,
criping
