In preparation for using vm_flags to ensure guard pages for shadow stacks supply them as an argument to generic_get_unmapped_area(). The only user outside of the core code is the PowerPC book3s64 implementation which is trivially wrapping the generic implementation in the radix_enabled() case. No functional changes.

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 reStructuredText 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.
