Subject: [PATCH v2 0/3] Hugetlb fault path to use struct vm_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.
----
v2:
  - renamed patchset from 'Define struct vm_fault in handle_mm_fault()'
  - Dropped patches 4/5 - These allowed vmf->{address,pgoff} to be
    modified, but that allows misuse of these fields. Converting hugetlb
    to using the same address/pgoff as generic mm is not simple, so that
    can be done later.

Vishal Moola (Oracle) (3):
  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
