Bug Description

[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.
