2.6 kernels don't have fixups defaulting to on.
And it's a lot more expensive.
Just because there is an expensive workaround doesn't mean it's not a bug. And
arguably even with hardware fixup it's still a bug and appallingly bad practice.
Let's not sweep this under the carpet, especially in something as critical as
e2fsprogs.

On ARM <v7, there are software fixups via trap, which is basically the
same as the hardware fixups but with a lot higher cost. For quite a few
kernel releases, fixups have defaulted to ON. Are we sure there's still
an issue here?
