Naresh, any chance you could test again adding the following:
diff --git a/arch/sh/kernel/vmlinux.lds.S b/arch/sh/kernel/vmlinux.lds.S index 3161b9ccd2a5..b6276a3521d7 100644 --- a/arch/sh/kernel/vmlinux.lds.S +++ b/arch/sh/kernel/vmlinux.lds.S @@ -4,6 +4,7 @@

*/ OUTPUT_ARCH(sh) +#define RUNTIME_DISCARD_EXIT #include <asm/thread_info.h> #include <asm/cache.h> #include <asm/vmlinux.lds.h>
My guess is build environment is using ld < 2.36?? and this is probably similar to: a494398bde27 ("s390: define RUNTIME_DISCARD_EXIT to fix link error with GNU ld < 2.36") 4b9880dbf3bd ("powerpc/vmlinux.lds: Define RUNTIME_DISCARD_EXIT")

This is also occurring in latest upstream:

These build errors started from v6.2-rc2 on the mainline [1] & [2].

FWIW, the above patch resolves this.
Yes. Tested and confirmed it fixes the reported problem.
How many more architectures need something similar?
Now I see it on sh with gcc-8 only on the mainline.
OTOH, It was noticed on earlier stable-rc 5.4 for x86, i386, powerpc, sh and s390.

v5.4 needs: 84d5f77fc2ee ("x86, vmlinux.lds: Add RUNTIME_DISCARD_EXIT to generic DISCARDS")
which didn't hit Linus's tree until: v5.7-rc1~164^2~1 This explains why v5.4 blew-up and v5.10 didn't.
I'm testing the following for v5.4
84d5f77fc2ee ("x86, vmlinux.lds: Add RUNTIME_DISCARD_EXIT to generic DISCARDS") This needed a little massaging to apply.
99cb0d917ffa ("arch: fix broken BuildID for arm64 and riscv") 4b9880dbf3bd ("powerpc/vmlinux.lds: Define RUNTIME_DISCARD_EXIT") 07b050f9290e ("powerpc/vmlinux.lds: Don't discard .rela* for relocatable builds") a494398bde27 ("s390: define RUNTIME_DISCARD_EXIT to fix link error with GNU ld < 2.36")
I'd be grateful if you could confirm - so I can send this full series to Greg.
If you'd rather - I can send the patch-series now for testing?
Please send your repo and branch. I will pick up and run tests on it.
