Changes from v5: - Rebase onto v5.8-rc7 to resolve Makefile conflict
v5: https://lore.kernel.org/lkml/20200715004133.1430068-1-nivedita@alum.mit.edu/
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.
Ard Biesheuvel (3): x86/boot/compressed: Move .got.plt entries out of the .got section x86/boot/compressed: Force hidden visibility for all symbol references x86/boot/compressed: Get rid of GOT fixup code
Arvind Sankar (4): x86/boot: Add .text.* to setup.ld x86/boot: Remove run-time relocations from .head.text code x86/boot: Remove run-time relocations from head_{32,64}.S x86/boot: Check that there are no run-time relocations
