Alexandre Ghiti <alexghiti@rivosinc.com> says: After multiple attempts, this patchset is now based on the fact that the 64b kernel mapping was moved outside the linear mapping. The first patch allows to build relocatable kernels but is not selected by default. That patch is a requirement for KASLR. The second and third patches take advantage of an already existing powerpc script that checks relocations at compile-time, and uses it for riscv. * b4-shazam-merge: riscv: Use --emit-relocs in order to move .rela.dyn in init riscv: Check relocations at compile time powerpc: Move script to check relocations at compile time in scripts/ riscv: Introduce CONFIG_RELOCATABLE riscv: Move .rela.dyn outside of init to avoid empty relocations riscv: Prepare EFI header for relocatable kernels Link: https://lore.kernel.org/r/20230329045329.64565-1-alexghiti@rivosinc.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
