Build ID is missing for arm64 with CONFIG_MODVERSIONS=y using ld >= 2.36
on 5.4, 5.10, and 5.15
Backport Build ID fixes, which work-around ld behavior by
modifying vmlinux linker script.
This has been build tested this on {x86_64, arm64, riscv, powerpc, s390, sh}.
Simple test case:
$ readelf -n vmlinux | grep "Build ID"
Changes for v3:
- per Greg, re-style backport of 84d5f77fc2ee ("x86, vmlinux.lds: Add RUNTIME_DISCARD_EXIT to generic DISCARDS")
- per Greg, add justification for backporting:
99cb0d917ffa ("arch: fix broken BuildID for arm64 and riscv")
which has "Fixes:" to v6.2 only content.
- rebase to 5.4.233
Changes for v2:
- rebase 6/6 c1c551bebf92 ("sh: define RUNTIME_DISCARD_EXIT") from upstream
