[PATCH Makedumpfile 0/4] x86_64: Fix page_offset for randomized base enabled

[Pratyush Anand]

Patch 1/4 fixes page_offset calculation, so that it is correctly calculated
on KASLR enabled kernel as well.
Patch 2/4 simplifies VA to PA translation. New code has been benchmarked
against old code on a 4T system.
Patch 3/4 and 4/4 is removal of (now) unnecessary code.

I think, we should find a way to kill find_vememmap() as well, so that
VMEMMAP_START can be removed. I have very limited idea about x86, so unable
to do that as of now.

Pratyush Anand (4):
  x86_64: Calculate page_offset from pt_load
  x86_64: translate all VA to PA using page table values
  x86_64: kill is_vmalloc_addr_x86_64()
  x86_64: kill some unused initialization
