Yes the arm fixes this misalignment. I did't say that anything doesn't work. But alignment fixup is an emulation which needs about 80 CPU cycles instead of three. So it is bad. > No. This is not the only place where kernel does unaligned accesses. I'm running the kernel in the emulator "softgun" which prints warning message on every unaligned instruction. I do not see any warning message. So my conclusion is that the kernel normaly does not a single unaligned access.
