+Adaption of a patch [A] applied to meta-arm for the kernel. But since TI has it's own
+kernel we have to "adjust" the patch to match our files.

+Subject: [PATCH] init_disassemble_info() signature changes causes compile
+ failures
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Hi,
+
+binutils changed the signature of init_disassemble_info(), which now causes
+perf and bpftool to fail to compile (e.g. on debian unstable).
+
+Relevant binutils commit: https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=60a3da00bd5407f07d64dff82a4dae98230dfaac
+
+util/annotate.c: In function ?symbol__disassemble_bpf?:
+util/annotate.c:1765:9: error: too few arguments to function ?init_disassemble_info?
+ 1765 | init_disassemble_info(&info, s,
+ | ^~~~~~~~~~~~~~~~~~~~~
+In file included from util/annotate.c:1718:
+/usr/include/dis-asm.h:472:13: note: declared here
+ 472 | extern void init_disassemble_info (struct disassemble_info *dinfo, void *stream,
+ | ^~~~~~~~~~~~~~~~~~~~~
+
+with equivalent failures in
+
+tools/bpf/bpf_jit_disasm.c
+tools/bpf/bpftool/jit_disasm.c
+
+The fix is easy enough, add a wrapper around fprintf() that conforms to the
+new signature.
+
+However I assume the necessary feature test and wrapper should only be added
+once? I don't know the kernel stuff well enough to choose the right structure
+here.
+
+Attached is my local fix for perf. Obviously would need work to be a real
+solution.
+
+Greetings,
+

+There is a proper fix in development upstream[2].
