[Bug 1354349] [NEW] trusty crash(7.0.3 based) can't support arm64

 

Public bug reported:

After investigation, looks VTOP() works mistakenly in current trusty
crash on arm64.

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?

https://github.com/crash-
utility/crash/commit/0f6d989aa091a97e979ea01fb15e05cc22673de7

 Updated the ARM64 implementation to support Linux 3.13 and later

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.
