4.19-stable review patch. If anyone has any objections, please let me know.
------------------ From: Yasha Cherikovsky <[email protected]> commit 3f0a53bc6482fb09770982a8447981260ea258dc upstream. This fixes booting with the combination of CONFIG_RELOCATABLE=y and CONFIG_MIPS_ELF_APPENDED_DTB=y. Sections that appear after the relocation table are not relocated on system boot (except .bss, which has special handling). With CONFIG_MIPS_ELF_APPENDED_DTB, the dtb is part of the vmlinux ELF, so it must be relocated together with everything else.
