[PATCH 5.10 fix build id for arm64 0/5]

Build ID on arm64 is broken if CONFIG_MODVERSIONS=y on 5.4, 5.10, and 5.15

I've build tested on {x86_64, arm64, riscv, powerpc, s390, sh}

Without these patches Build ID is missing for arm64 (ld >= 2.36):

$ readelf -n vmlinux | grep "Build ID"

*NOTE* to following is not in mainline, yet: [PATCH 5.10 fix build id for arm64 5/5] sh: define RUNTIME_DISCARD_EXIT https://lore.kernel.org/all/9166a8abdc0f979e50377e61780a4bba1dfa2f52.1674518...

Masahiro Yamada (2): arch: fix broken BuildID for arm64 and riscv s390: define RUNTIME_DISCARD_EXIT to fix link error with GNU ld < 2.36

Michael Ellerman (2): powerpc/vmlinux.lds: Define RUNTIME_DISCARD_EXIT powerpc/vmlinux.lds: Don't discard .rela* for relocatable builds
