Move the on-demand allocation of the pae_root and lm_root pages, used by nested NPT for 32-bit L1s, into a separate helper. This will allow a future patch to hold mmu_lock while allocating the non-special roots so that make_mmu_pages_available() can be checked once at the start of root allocation, and thus avoid having to deal with failure in the middle of root allocation.

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.
