Dave Young 658db69940 Support kdump for kaslr enabled Fedora kernel
Since in Fedora 25 kernel kaslr is enabled (x86) but makedumpfile can not save
a correct vmcore, so it means kdump default setup will not work.

Pratyush posted a patch series to upstream which can fix the issue. Let's merge them in F25, will get the normal fixes after it being merged in upstream, we hopefully can rebase soon in rawhide.

This is an urgent fix for F25 since F25 freeze is this week.

VMALLOC_START, VMALLOC_END, MODULES_VADDR and MODULES_END are mo more
needed for x86_64 now. So, kill their initialization.
