Linus Torvalds ebad825cdd ia64: mark special ia64 memory areas anonymous ... Commit bfd40eaff5 ("mm: fix vma_is_anonymous() false-positives") made newly allocated vma's have a dummy vm_ops field so that they wouldn't be mistaken for anonymous mappings, and if you wanted an anonymous vma you had to explicitly say so by calling "vma_set_anonymous()" on it. However, it missed the two special vmas that ia64 processes have: the register backing store and the NaT page. So they wouldn't actually act like anonymous ranges, and page faults on them caused a SIGBUS rather than the creation of a new anon page in them. That obviously will make any ia64 binary very unhappy indeed, and the boot fails early.
