Move the APIC access page allocation helper function to common x86 code, the allocation routine is virtually identical between APICv (VMX) and AVIC (SVM). Keep APICv's gfn_to_page() + put_page() sequence, which verifies that a backing page can be allocated, i.e. that the system isn't under heavy memory pressure. Forcing the backing page to be populated isn't strictly necessary, but skipping the effective prefetch only delays the inevitable.

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.
