IBM Cell Blades used the Cell processor and the "blade" server form factor. They were sold as models QS20, QS21 & QS22 from roughly 2006 to 2012 [1]. They were used in a few supercomputers (eg. Roadrunner) that have since been dismantled, and were not that widely used otherwise. Until recently I still had a working QS22, which meant I was able to keep the platform support working, but unfortunately that machine has now died. I'm not aware of any users. If there is a user that wants to keep the upstream support working, we can look at bringing some of the code back as appropriate. See previous discussion at [2]. Remove the top-level config symbol PPC_IBM_CELL_BLADE, and then the dependent symbols PPC_CELL_NATIVE, PPC_CELL_COMMON, CBE_RAS, PPC_IBM_CELL_RESETBUTTON, PPC_IBM_CELL_POWERBUTTON, CBE_THERM, and AXON_MSI. Then remove the associated C files and headers, and trim unused header content (some is shared with PS3). Note that PPC_CELL_COMMON sounds like it would build code shared with PS3, but it does not. It's a relic from when code was shared between the Blade support and QPACE support. Most of the primary authors already have CREDITS entries, with the exception of Christian, so add one for him.

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.
