Hi all,

The VDSO is just a few pages and there's no actual cost at injecting those
page into a process address space at the very begining.
On the other hand, taking care of VDSO on the userfaultfd side creates
undesired complexity which may be avoided.

  uffd: do not treat VDSO pages as lazy
  uffd: remove handling of VDSO pages
