+Subject: [PATCH] modpost needs to cope with new glibc elf header on sparc
+Date:	Wed, 13 Jul 2005 08:25:49 +0200 (CEST)
+
+Hi everybody,
+
+recently a change in the glibc elf.h header has been introduced causing
+modpost to spawn tons of warnings (like the one below) building the kernel on sparc:
+
+[SNIP]
+** Warning: "current_thread_info_reg" [net/sunrpc/auth_gss/auth_rpcgss.ko] undefined!
+** Warning: "" [net/sunrpc/auth_gss/auth_rpcgss.ko] undefined!
+** Warning: "" [net/sunrpc/auth_gss/auth_rpcgss.ko] undefined!
+[SNIP]
+
+Ben Collins discovered that the STT_REGISTERED did change and that this change
+needs to be propagated to modpost.
+
+-#define STT_REGISTER   13              /* Global register reserved to app. */
++#define STT_SPARC_REGISTER     13      /* Global register reserved to app. */
+
+I did and tested this simple patch to maintain compatibility with newer (>= 2.3.4)
+and older (<= 2.3.2) glibc.
+
+Please apply.
