Sorry. I am not sure what you means by playing with ABI changes. I had
thought that you mean the changes in GDB's side. But it seems that you
are meaning the changes in kernel's side.
And yes, Anton give me a patch to assign the faulting data address to
siginfo.si_addr. But in my opinion, it is a small patch. Just that I
didn't get out the same value in gdb as that assigned to si_addr in
kernel. We are now believing that it might be a 32/64bit siginfo issue.
But I don't have machine available at this time to track that down.
(Another guy need to work with the shipped kernel.)
