Replace a nasty hack with a different nasty hack to prepare for multipage bio_vecs. By moving the temporary page array as far up as possible in the space allocated for the bio_vec array we can iterate forward over it and thus use bio_add_page. Using bio_add_page means we'll be able to merge physically contiguous pages once support for multipath bio_vecs is merged.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
