Rather than flood the mailing list with the patches, I've arranged for a git
repo to hold the changesets.
You can find the repo here:
<https://github.com/jimix/linux-bgq>
They are against GregKH's linux-stable.git long-term 3.4.y (y=22) branch.
The first 9 (6e58088f..) effect common code and the rest are BGQ specific.
Here is a are the summary logs:

powerpc/book3e: Remove config for PPC_A2_DD2 since there is no reference to
it
This must have been leftover from early DD1 days which is not
present in any current kernel code.

powerpc/dcr: Some native DCR fixes
The following fixes have been made:
- dcr_read/write_native() must use the indexed version of the
m[ft]dcrx since the non-indexed version only allows a 10-bit
numerical space, but the C interface allows a full 32-bits.
- C bindings for m[ft]dcrx, and the "table" versions, should use
"unsigned long" so that they are 64/32 bit neutral.
- The "table" versions (__m[ft]cdr) should obtain the table address
with LOAD_REG_ADDR(), this will also make it 64/32bit neutral.

powerpc/boot: Add a "spin_threads" hook to platform_ops
It is useful for the boot program to arrange for all secondary cpus
and threads to enter the kernel in a "kexec" fashion. This hook makes
it possible.

powerpc/kexec: Add kexec "hold" support for Book3e processors
This patch add two items:
1) Book3e requires that GPR4 survive the "hold" process, so we make
sure that happens.
2) Book3e has no real mode, and the hold code exploits this. Since
these processors ares always translated, we arrange for the kexeced
threads to enter the hold code using the normal kernel linear mapping.

powerpc: Remove unecessary VSX symbols
The symbol THREAD_VSR0 is defined to be the same as THREAD_FPR0. Its

powerpc/book3e: IBM Blue Gene/Q Boot
This patch specifically deals with the initial program load
environment so that a boot image (dtbImage.bgq) can be loaded by the
BGQ management tools. The boot code is a little odd because it has to
deal with the following issues:
- Linux boot image wrappers are 32-bit programs
- BGQ Tools only load 64bit ELF programs
- BGQ Firmware information is typically loaded at an address > 4G
- BGQ FW information contains 64-bit ABI function pointers (which are
actually function descriptors) to access firmware methods
- BGQ FW methods must be called in 64-bit mode

powerpc/book3e: IBM Blue Gene/Q Quad Processing eXtention (QPX)
This enables kernel support for the QPX extention and is intended for
processors that support it, usually an IBM Blue Gene processor.
Turning it on does not effect other processors but it does add code
and will quadruple the per thread save and restore area for the FPU
(hense the name). If you have enabled VSX it will only double the
space.
