Hi Al,
As of commit fea82210 ("m68k: switch to saner kernel_execve()
semantics") I can't get non-mmu m68k targets to boot through to
user space. I don't think this commit itself is the problem, but
probably something in the generic execve changes.
What I see is that it boots up to trying to exec

Heh, when making patches for other subsystems, I look at the subject of
the patch that broke to determine what to use.

Hi,
after my recent tirade of very poor device support of Aspire One,
I now experienced something a lot worse (bad karma? ;-P):
basically my entire ext4 root partition got blewn into shreds
(corruption is so pervasive that I'm afraid recovery will fail).
I am (was) running 3.7.0, and decided to

Would be nice to have a patch against -tip, as we already have

Which creates a conflict.
