[0/5] Define struct vm_fault in handle_mm_fault()

This patchset converts the hugetlb fault path to use struct vm_fault.
This helps make the code more readable, and alleviates the stack by
allowing us to consolidate many fault-related variables into an
individual pointer.

Defining the vm_fault in handle_mm_fault() and passing it to
hugetlb_fault() and __handle_mm_fault() has the additional benefit of
standardizing some variable names between hugetlbfs and the rest of mm
as well.

  hugetlb: Convert hugetlb_fault() to use struct vm_fault
  hugetlb: Convert hugetlb_no_page() to use struct vm_fault
  hugetlb: Convert hugetlb_wp() to use struct vm_fault
  mm: Make pgoff non-const in struct vm_fault
  memory: Define struct vm_fault in handle_mm_fault()
