Changes from v5:
- Rebase onto v5.8-rc7 to resolve Makefile conflict
v5: https://lore.kernel.org/lkml/[email protected]/
Changes from v4:
- Move -pie --no-dynamic-linker from KBUILD_LDFLAGS to LDFLAGS_vmlinux
Sedat: I'm not clear on whether you tested with the final LDFLAGS,
could you confirm: i.e. if you tested with -pie passed to LLD?
- Replace runtime -> run-time to be consistent in wording
Changes from v3:
- Move hidden.h to include/linux so the EFI stub and the compressed
kernel can share the same file
Changes from v2:
- Incorporate Ard's patches for eliminating GOT references into this
series
- Rebase on v5.8-rc3
Changes from v1:
- Add .text.* to setup.ld instead of just .text.startup
- Rename the la() macro introduced in the second patch for 64-bit to
rva(), and rework the explanatory comment.
- In the last patch, check both .rel.dyn and .rela.dyn, instead of just
one per arch.
