Hi Arun,

An updated version of this patch set got just posted at:

After learning more about the internals of libunwind I decided to replace the 
arm_stackframe and let the extbtl-parser operate on the dwarf_cursor directly. 
This eliminates the need to synchronize the two models and clears the way for 
call stacks with mixed DWARF- and extbl-frames. It also fixes the testcase 
errors that Henrik reported.
Since the first version of the patch set went upsteam the updated series won't 
apply anymore. How do we want to proceed here? Do you want me to rebase the 
new series against the current head or do you wan't to revert the initial 
patch set?
