[PATCH] kbuild: modpost needs to cope with new glibc elf header on sparc
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 definition in glibc did change and that this change needs to be propagated to modpost. glibc change: -#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.
