From fbe6e37dab974dd0fc3660c001895f7bfd771c9a Mon Sep 17 00:00:00 2001 From: Nicholas Piggin <npiggin@gmail.com> Date: Wed, 24 Aug 2016 22:29:21 +1000 Subject: kbuild: add arch specific post-link Makefile Allow architectures to create arch/xxx/Makefile.postlink with targets for vmlinux, modules.ko, and clean, which will be invoked after final linking of vmlinux and modules. powerpc will use this to check vmlinux linker relocations for sanity, and may use it to fix up alternate instruction patch branch addresses.
