Hi Matthias,

The proposal is to turn on LTO by default on most 64bit release
architectures. Not proposing to do this on 32bit architectures because
of the limited address space at link time, and up to now nobody tested
LTO on 32bit archs. In test

The 32-bit ARM kernel implements fixups on behalf of user space when
using LDM/STM or LDRD/STRD instructions on addresses that are not 32-bit
aligned. This is not something that is supported by the architecture,
but was done anyway to increase compatibility with user space software,
