Lokesh Gidra 32af81af2f mm: add vma_assert_locked() for !CONFIG_PER_VMA_LOCK
vma_assert_locked() is needed to replace mmap_assert_locked() once we
start using per-vma locks in userfaultfd operations.

In !CONFIG_PER_VMA_LOCK case when mm is locked, it implies that the given
VMA is locked.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
