[GIT PULL] DWARF unwinder updates for 2.6.34

[GIT PULL] DWARF unwinder updates for 2.6.34

[Matt Fleming]

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.
