There is no longer an ia64-specific version of the errno.h header below arch/ia64/include/uapi/asm/, so trying to build tools/bpf fails with: CC /usr/src/linux/tools/bpf/bpftool/btf_dumper.o In file included from /usr/src/linux/tools/include/linux/err.h:8, from btf_dumper.c:11: /usr/src/linux/tools/include/uapi/asm/errno.h:13:10: fatal error: ../../../arch/ia64/include/uapi/asm/errno.h: No such file or directory 13 | #include "../../../arch/ia64/include/uapi/asm/errno.h" | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ compilation terminated. Thus, just remove the inclusion of the ia64-specific errno.h so that the build will use the generic errno.h header on this target which was used there anyway as the ia64-specific errno.h was just a wrapper for the generic header.
