Now that it's madvisable, remove two pieces of VM_DONTCOPY bogosity:
1. There was and is no logical reason why VM_DONTCOPY should be in the
list of flags which forbid vma merging (and those drivers which set
it are also setting VM_IO, which itself forbids the merge).
2. It's hard to understand the purpose of the VM_HUGETLB, VM_DONTCOPY
block in vm_stat_account: but never mind, it's under CONFIG_HUGETLB,
which (unlike CONFIG_HUGETLB_PAGE or CONFIG_HUGETLBFS) has never been
defined.
