Subject: [PATCH 5.15 v2 0/5] Fix Build ID on arm64 if CONFIG_MODVERSIONS=y
Date: Fri, 10 Feb 2023 13:18:39 -0700	[thread overview]
Message-ID: <20230210-tsaeger-upstream-linux-stable-5-15-v2-0-6c68622745e9@oracle.com> (raw)

Build ID is missing for arm64 with CONFIG_MODVERSIONS=y using ld >= 2.36
on 5.4, 5.10, and 5.15

Backport BuildID fixes.

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

  # view Build ID
  $ readelf -n vmlinux | grep "Build ID"

Changes for v2:
- rebase 5/5 c1c551bebf92 ("sh: define RUNTIME_DISCARD_EXIT") from upstream
