Subject: ppc/xics: add a XICSState backlink in ICPState
X-Git-Tag: qemu-xen-4.9.0-rc1~110^2~56
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=d49c603b37e6c9d025f58c09f55d0c7cefe88987;p=qemu-xen.git

ppc/xics: add a XICSState backlink in ICPState

The link will be used to change the API of the icp_* routines which
are still using an XICSState as an argument.
