[PATCH 0/8] Sort out mess in __do_fault()

["Kirill A. Shutemov" <kirill.shutemov@linux.intel.com>]

From: "Kirill A. Shutemov" <kirill@shutemov.name>

Current __do_fault() is awful and unmaintainable. These patches try to
sort it out by split __do_fault() into three destinct codepaths:
 - to handle read page fault;
 - to handle write page fault to private mappings;
 - to handle write page fault to shared mappings;

I also found page refcount leak in PageHWPoison() path of __do_fault().

Kirill A. Shutemov (8):
  mm, hwpoison: release page on PageHWPoison() in __do_fault()
  mm: rename __do_fault() -> do_fault()
  mm: do_fault(): extract to call vm_ops->do_fault() to separate
    function
  mm: introduce do_read_fault()
  mm: introduce do_cow_fault()
  mm: introduce do_shared_fault() and drop do_fault()
  mm: consolidate code to call vm_ops->page_mkwrite()
  mm: consolidate code to setup pte
