** Description changed:

- After investigation, looks VTOP() works mistakenly in current trusty
- crash on arm64.
+ ****************
+ HOW TO REPRODUCE
+ ****************
  
- With the commit below, crash starts to working on arm64, and it can be
- applied cleanly on trusty crash, so could you guys merge it?
+ On an system that uses the ARM64 architecture, run the "crash" utility.

+ ******************
+ EXPECTED BEHAVIOUR
+ ******************
  
-  Updated the ARM64 implementation to support Linux 3.13 and later
+ - The "crash" utility to work.
  
- kernels that expand to a 42-bit address space when 64K pages are
- configured. This is also the first crash version that has been
- tested on a live ARM64 system with 4K pages, where it cleanly
- make it to the "crash>" prompt. However, it should be noted that
- some commands (most notably "bt") still do not work as of yet.

+ **************
+ REAL BEHAVIOUR
+ **************
  
+ - The "crash" utility doesn't work.
  
- [Impact]
- crash package in trusty can't be used on arm64
+ ************
+ PROPOSED FIX
+ ************
  
- [Test Case]
- just run crash on arm64 box
+ - To clean merge into Ubuntu the <https://github.com/crash-
+ utility/crash/commit/0f6d989aa091a97e979ea01fb15e05cc22673de7> commit,
+ which updates the ARM64 implementation to support Linux 3.13 and later.
  
- [Regression Potential]
- the change is arm64-only related, so no potential regression
+ - Since the change only affects the ARM64 architecture, there is no
+ potential regression.
+ 
+ ****************
+ RELEVANT DETAILS
+ ****************
+ 
+ - The package's affected versions are the 7.0.6 based.

+ - Dave Anderson at
