Looks good to me, Reviewed-by: Arnd Bergmann <[email protected]> Please add it to Russell's patch tracker if you haven't already. Most of the .config files that don't set AEABI (and a lot of the others as well) have likely never been booted on real hardware with a modern kernel in a long time. There have not been any distros using OABI in a long time (Debian Lenny was released in 2009), and gcc dropped support for it a few years later. We could probably change most of these to use OABI_COMPAT instead, aside from any ones that Russell wants to keep building as OABI for his own machines. Arnd
