Thread-topic: [PATCH 08/27] ia64/xen: define helper functions for xen hypercalls.
+/*
+ * Hypercalls without parameter.
+ */
+#define __HCALL0(name,hcall)           \
+       GLOBAL_ENTRY(name);             \
+       break   hcall;                  \

Should Linux code be made aware of the "break" numbers that
are being used for hypercalls (so it doesn't try to re-use
them for something else?)  include/asm-ia64/break.h should be
updated with the appropriate stuff (just with a base value
and a comment for how many you are using ... you can still
define all the HYPERPRIVOP_* defines in a separate file).
