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.

This patch adds the SPU event based profiling funcitonality for the
IBM Cell processor. Previously, the CELL OProfile kernel code supported
PPU event, PPU cycle profiling and SPU cycle profiling. The addition of
SPU event profiling allows the users to identify where in their SPU code
various SPU evnets are occuring. This should help users further identify
issues with their code. Note, SPU profiling has some limitations due to HW
constraints. Only one event at a time can be used for profiling and SPU event
profiling must be time sliced across all of the SPUs in a node.
The patch adds a new arch specific file to the OProfile file system. The
file has bit 0 set to indicate that the kernel supports SPU event profiling.
The user tool must check this file/bit to make sure the kernel supports
SPU event profiling before trying to do SPU event profiling. The user tool
check is part of the user tool patch for SPU event profiling.

from include/asm-powerpc. This is the result of a
mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm
Followed by a few documentation/comment fixups and a couple of places
where <asm-powepc/...> was being used explicitly. Of the latter only
one was outside the arch code and it is a driver only built for powerpc.
