Title:
arm64: crash: invalid/unsupported page size: 6144
Status in crash package in Ubuntu:

Bug description:
[Impact]
crash in ARM64 can't be used on ubuntu trusty, utopic and vivid when
debugging a new kernel like 4.1-rc+
[Test Case]
sudo crash ~/vmlinux
crash will exit with failure log of 'crash: invalid/unknown page size:
6144', see detailed steps in [1].
[Regression Potential]
The proposed patch has been merged upstream, so there shouldn't be
potential regression.
Also These changes are to code that only gets compiled on arm64, so
there's no risk to other architectures.
[Other Info]
After running crash from trusty, the failure log in [1] can be
observed.
Then I built crash from wily directly, the similar failure[2] can be
observed too.
