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.
