RE: [PATCH] cleanup legacy console_print function

["Anirban Sinha" <ASinha@zeugmasystems.com>]

Oops! Sorry for breaking the build. I do not have a intel 64 machine to
try my change. However, I believe this will help:

diff --git a/arch/ia64/kernel/head.h b/arch/ia64/kernel/head.h
index 2e2ac68..e762125 100644
--- a/arch/ia64/kernel/head.h
+++ b/arch/ia64/kernel/head.h
@@ -1 +1,3 @@
+#ifndef __ASSEMBLY__
 extern void console_print(const char *s);
+#endif


Can you please try this patch and test if this fixed it. If it does, I
will go ahead, commit the change locally and post the final patch.

   Ani
