# User Ian Campbell <ian.campbell@citrix.com> # Date 1282671421 -3600 # Node ID d1dd29a470ef1b9d2c77478a123326036dfe90bb # Parent d7a4adad9c328decbd384d87b23001aea8951b86 tools/libxc, tools/libelf: Relicense under LGPL v2.1 Relicense these two libraries under LGPL v2.1 only except where individual files already included the "or later" provision. Copyright holders have been contacted by Stephen Spector and have all agreed this change. Removed tools/libxc/ia64/aclinux.h since it appeared to be unused. There is a separate, more up to date, copy in xen/include/acpi/platform/aclinux.h which does appear to be used. Clarify the license of MiniOS privcmd.h under the same terms as other tools/include/xen-sys headers.
