On Octal DTR capable flashes like Micron Xcella reads cannot start or end at an odd address in Octal DTR mode. Extra bytes need to be read at the start or end to make sure both the start address and length remain even. To avoid allocating too much extra memory, thereby putting unnecessary memory pressure on the system, the temporary buffer containing the extra padding bytes is capped at PAGE_SIZE bytes. The rest of the 2-byte aligned part should be read directly in the main buffer.

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.
