Public bug reported:
[Impact]
Users of kdump won't be able to dump if their system uses hugepages/hugepagesz
on the cmdline.
[Test Case]
1) Install crashdump
2) Boot machine with hugepages= or hugepagesz= set to a significant amount of
memory
3) Try to crash with 'echo 'c' | sudo tee /proc/sysrq-trigger'
[Regression Potential]
If users really want to have hugepages/hugepagesz on the kexec'd kernel for
kdump they can add this via KDUMP_CMDLINE_APPEND in /etc/default/kdump-tools.
This patch should also potentially go upstream.
