It's not for mips-next as it should go into this cycle as a [hot]fix. I haven't added any "Fixes:" tag since these warnings is a result of merging several sets and of certain build configurations that almost couldn't be tested separately. > diff --git a/include/asm-generic/vmlinux.lds.h b/include/asm-generic/vmlinux.lds.h > index 01a3fd6a64d2..c887ac36c1b4 100644 > --- a/include/asm-generic/vmlinux.lds.h > +++ b/include/asm-generic/vmlinux.lds.h > @@ -95,7 +95,7 @@ > */ > #ifdef CONFIG_LD_DEAD_CODE_DATA_ELIMINATION > #define TEXT_MAIN .text .text.[0-9a-zA-Z_]* > -#define DATA_MAIN .data .data.[0-9a-zA-Z_]* .data..L* .data..compoundliteral* .data.$__unnamed_* .data.$Lubsan_* > +#define DATA_MAIN .data .data.[0-9a-zA-Z_]* .data..L* .data..compoundliteral* .data.$__unnamed_* .data.$L* > #define SDATA_MAIN .sdata .sdata.[0-9a-zA-Z_]* > #define RODATA_MAIN .rodata .rodata.[0-9a-zA-Z_]* .rodata..L* > #define BSS_MAIN .bss .bss.[0-9a-zA-Z_]* .bss..compoundliteral* > -- > 2.30.1 Thanks, Al

I'll send another pull request to Linus and will add this patch to it. Thomas.
