Alex Elder says: ==================== net: ipa: support 32-bit targets There is currently a configuration dependency that restricts IPA to be supported only on 64-bit machines. There are only a few things that really require that, and those are fixed in this series. The last patch in the series removes the CONFIG_64BIT build dependency for IPA. Version 2 of this series uses upper_32_bits() rather than creating a new function to extract bits out of a DMA address. Version 3 of uses lower_32_bits() as well. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
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.
