[Xen-devel] PATCH: remove perfcounter array bound

[Tristan Gingold <Tristan.Gingold@xxxxxxxx>]

Hi,

the current dom0_perfcounter hypercall has a limit on the number of values per 
counter (64).  On ia64 we'd like to use arrays bigger than this limit.
This patch removes this hard-limit: perfcounter descriptors and values are now 
passed by two distinct buffers.

This break the API compatibility.  However because DOM0_PERFCCONTROL is used 
only by xenperf and only by developpers the patch didn't change 
DOM0_INTERFACE_VERSION.

Tested on ia64.

Tristan.
