Why is this comment getting removed?
When using KBUILD_VMLINUX_LIBS_PRELINK or KBUILD_VMLINUX_LIBS_FINAL,
drivers/firmware/efi/libstub/lib.a needs to be linked to the final
vmlinux with vmlinux.o, so I thought the above comment is not proper,
it I misunderstood it, I will keep the comment as is.
objs=vmlinux.o
- libs=
+ libs="${KBUILD_VMLINUX_LIBS_PRELINK}"
else
objs=vmlinux.a
- libs="${KBUILD_VMLINUX_LIBS}"
+ libs="${KBUILD_VMLINUX_LIBS} ${KBUILD_VMLINUX_LIBS_PRELINK}"

if is_enabled CONFIG_GENERIC_BUILTIN_DTB; then
FYI, the previous patch is still under discussion yesterday [1],
I do not know whether this patch is necessary and what is the next
step [2].
