Miller <davem@davemloft.net> Yeah, I had submitted a fix a long time before. https://lore.kernel.org/patchwork/patch/1130469/ I do not know why it was not picked up. It is OK whether any patch is picked up as long as the build error is fixed. (I think CFLAGS_REMOVE_vdso32/vdso-note.o should be added too, though)

It wasn't added for x86, and it compiles without, so I rather left it alone. Guenter

After looking at the code closer, I believe your code is more correct. vdso-note is assembly instead of C. arch/sparc/vdso/vdso-note.S arch/sparc/vdso/vdso32/vdso-note.S The -pg flag is added by the top Makefile, only for C files. CFLAGS_REMOVE_vdso-note.o = -pg was unneeded in the first place. BTW, I just thought this patch was supposed to be applied by Dave since it is touching a single file in arch/sparc/. If Dave plans to pick up this, please feel free to add: Reviewed-by: Masahiro Yamada <yamada.masahiro@socionext.com> If I should apply this to kbuild tree, please let me know.
