Author: ian Date: Sun May 17 17:03:37 2015 New Revision: 283033 URL: https://svnweb.freebsd.org/changeset/base/283033 Log: Do not set preload_addr_relocate for ARM. Apparently there was a time when loader(8) passed physical addresses in loader metadata for arm, but that is no longer true; all metadata has already been adjusted to vitual addresses by loader. I can't track down the exact revision in loader where a change from physical to virtual metadata addresses happened. The code involved is very twisty and complicated. I suspect the change was an unintended consequence of the r247301, r247413, r248118 series of changes I made a couple years ago.
