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.

The device tree infrastructure is being genericized so its documentation

Documentation/powerpc/smp.txt is so outdated that it makes sense to just

commit 14cf11af6cf608eb8c23e989ddb17a715ddce109 ("powerpc: Merge enough to
start building in arch/powerpc.") unwired /proc/ppc_htab, and commit
917f0af9e5a9ceecf9e72537fabb501254ba321d ("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.

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.

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.

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!
