b2677b8dd8 KVM: PPC: Remove 440 support
The 440 target hasn't been properly functioning for a few releases and
before I was the only one who fixes a very serious bug that indicates to
me that nobody used it before either.

Furthermore KVM on 440 is slow to the extent of unusable.

We don't have to carry along completely unused code. Remove 440 and give
us one less thing to worry about.

330a1eb777 powerpc/perf: Core EBB support for 64-bit book3s
Add support for EBB (Event Based Branches) on 64-bit book3s. See the
included documentation for more details.

EBBs are a feature which allows the hardware to branch directly to a
specified user space address when a PMU event overflows. This can be
used by programs for self-monitoring with no kernel involvement in the
inner loop.

Most of the logic is in the generic book3s code, primarily to avoid a
proliferation of PMU callbacks.

Documentation/powerpc/smp.txt is so outdated that it makes sense to just

1b483a6a7b powerpc: Remove remains of /proc/ppc_htab
commit 14cf11af6c ("powerpc: Merge enough to
start building in arch/powerpc.") unwired /proc/ppc_htab, and commit
917f0af9e5 ("powerpc: Remove arch/ppc and
include/asm-ppc") removed the rest of the /proc/ppc_htab support, but there are
still a few references left. Kill them for good.

74deace2f9 Documentation: remove old sbc8260 board specific information
This file contains 8 yr. old board specific information that was for
the now gone ppc implementation, and it pre-dates widespread u-boot
support.  Any of the technical details of the board memory map would be
more appropriately captured in a dts if I revive it as powerpc anyway.

bc556ba940 [POWERPC] QE: Add ability to upload QE firmware
Define the layout of a binary blob that contains a QE firmware and instructions
on how to upload it.  Add function qe_upload_firmware() to parse the blob
and perform the actual upload.  Fully define 'struct rsp' in immap_qe.h to
include the actual RISC Special Registers.  Added description of a new
QE firmware node to booting-without-of.txt.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
