Jivin Mike Frysinger lays it down ... > The recent commit 1f0ce8b3dd667dca7 which moved the ARCH_SLAB_MINALIGN > default into the global header inadvertently broke FLAT for a bunch of > systems. Blackfin systems now fail on any FLAT exec with: > Unable to read code+data+bss, errno 14 > When your /init is a FLAT binary, obviously this can be annoying ;). > > This stems from the alignment usage in the FLAT loader. The behavior > before was that FLAT would default to ARCH_SLAB_MINALIGN only if it was > defined, and this was only defined by arches when they wanted a larger > alignment value. Otherwise it'd default to pointer alignment. Arguably, > this is kind of hokey that the FLAT is semi-abusing defines it shouldn't. > > But let's ignore that and simply ignore min alignment values of 0. > > Signed-off-by: Mike Frysinger <vap...@gentoo.org>
