Was me actually ... mine looked like this:
+#ifdef CONFIG_NUMA
+extern acpi_status acpi_map_iosapic (acpi_handle, u32, void*, void**);
+#define map_apics() acpi_get_devices(NULL, acpi_map_iosapic, NULL, NULL);
+#else
+#define map_apics() do { } while (0);
+#endif
+
[...]
-#ifdef CONFIG_NUMA
-extern acpi_status acpi_map_iosapic (acpi_handle, u32, void*, void**);
-
- acpi_get_devices(NULL, acpi_map_iosapic, NULL, NULL);
-#endif
+ map_apics();
but yours has probbaly even been compiled, and stuff.

"Next the statesmen will invent cheap lies, putting the blame upon
the nation that is attacked, and every man will be glad of those
conscience-soothing falsities, and will diligently study them, and refuse
to examine any refutations of them; and thus he will by and by convince
himself that the war is just, and will thank God for the better sleep
he enjoys after this process of grotesque self-deception." -- Mark Twain

Yeah, but I'm happy with either one, they look equivalent (except yours has
';' at the end of the #defines).
Thanks,
