Re: [XenPPC] [PATCH 1/4] move shared page definitions to public header
No need to respin, since this can wait for a follow-on/dom0 work, we
can lose:
+#define RMA_LAST_DOM0 2
+/* these are not used for dom0 so they should be last */
+#define RMA_CONSOLE 3
+#define RMA_STORE 4
+#define RMA_LAST_DOMU 4
Since dom0 does not use them, and
And when dom0 goes flat we can lose the rest.
The domU shared info page can be obtained from XEN_DOMCTL_getdomaininfo
Another option is that we could simply drop this patch all together
since the contents will go away.
