Subject: s/Index/Cpu in the SYSTEM code where 'Index' relates to a processor
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=e616b4e7cc286ad71b66f338a9e3c4492140e964;p=pvdrivers%2Fwin%2Fxenbus.git

s/Index/Cpu in the SYSTEM code where 'Index' relates to a processor

This is a purely cosmetic patch. No functional change.
