DWARF unwinder updates for 2.6.34
Paul,
I've got a bunch of DWARF unwinder patches in my tree. There are 3 bug fixes but I'm guessing -rc7 is too late in the game for applying them? I'm assuming that they will fix the issues you were seeing on qemu but I haven't been able to test qemu recently so I'm not sure.
The following changes since commit 93e2b9ece0c619ff69d110df28594439882c7737:
Paul Mundt (1):
sh: Fix up large system memory handling for SH7780 PCI.
are available in the git repository at:
git://github.com/mfleming/linux-2.6.git sh/dwarf-unwinder
Matt Fleming (5):
sh: Correct the offset of the return address in ret_from_exception
sh: Setup frame pointer in handle_exception path
sh: Don't continue unwinding across interrupts
sh: Remove superfluous setup_frame_reg call
sh: Optimise FDE/CIE lookup by using red-black trees

They look reasonable for 2.6.33, so I've cherry-picked the bugfixes there. I'll roll the rbtree patch in on top of those for 2.6.34.

I'll test it out later today, thanks.
