The Octeon usb driver has been in staging for a long time and used in
Ubiquiti routers for a while now.
It's been built and then tested on real hardware with several usb devices
and it is proven to be stable and ready to be moved to its proper place
in the kernel tree.
Move it to drivers/usb/host and adjust its Makefile, Kconfig and defconfig
dependencies.
Many thanks to the developers who made it happen.

Looks like almost all changes to this driver had been tree-wide
refactoring since git era begun. There is one commit from Al
15 years ago which could potentially be fixing a real bug.
The driver is using virt_to_bus() and is a real magnet for pointless
cleanups. It seems unlikely to have real users. Let's try to shed
this maintenance burden.

The driver for ATM Ambassador devices spews build warnings on
microblaze. The virt_to_bus() calls discard the volatile keyword.
The right thing to do would be to migrate this driver to a modern
DMA API but it seems unlikely anyone is actually using it.
There had been no fixes or functional changes here since
the git era begun.
In fact it sounds like the FW loading was broken from 2008
'til 2012 - see commit fcdc90b025 ("atm: forever loop loading
ambassador firmware").
Let's remove this driver, there isn't much changing in the APIs,
if users come forward we can apologize and revert.

This configuration is useful for boot testing malta_defconfig in QEMU
with just a simple cpio initrd, instead of a full ext4 rootfs.
This results in an increase of ~164KB of vmlinux (with GCC 11.2.0):
$ diskus vmlinux.before
11.19 MB (11,194,368 bytes)
$ diskus vmlinux.after
11.36 MB (11,358,208 bytes)
This size increase comes from the fact that usr/Kconfig is sourced when
CONFIG_BLK_DEV_INITRD is enabled, which defaults to supporting several
decompression algorithms for compressed initrds. This seems like a
reasonable tradeoff but these configurations could be disabled in the
future if there are complaints about the size increase.

This removes the driver on the premise that it has been unused for a long
time. This is a better approach compared to changing untestable code
nobody cares about in the first place. Similarly, the umem.com website now
shows a mere Godaddy parking add.

bpftrace is a high-level tracing language for Linux enhanced Berkeley
Packet Filter (eBPF) available in recent Linux kernels (4.x). bpftrace
uses LLVM as a backend to compile scripts to BPF-bytecode and makes use
of BCC for interacting with the Linux BPF system, as well as existing
Linux tracing capabilities: kernel dynamic tracing (kprobes), user-level
dynamic tracing (uprobes), and tracepoints.
According to Linux Kernel Requirements in bpftrace/INSTALL.md [1], the
kernel needs to be built with the following options:
CONFIG_BPF=y
CONFIG_BPF_SYSCALL=y
CONFIG_BPF_JIT=y
CONFIG_HAVE_EBPF_JIT=y
CONFIG_BPF_EVENTS=y
CONFIG_FTRACE_SYSCALLS=y
CONFIG_FUNCTION_TRACER=y
CONFIG_HAVE_DYNAMIC_FTRACE=y
CONFIG_DYNAMIC_FTRACE=y
CONFIG_HAVE_KPROBES=y
CONFIG_KPROBES=y
CONFIG_KPROBE_EVENTS=y
CONFIG_ARCH_SUPPORTS_UPROBES=y
CONFIG_UPROBES=y
CONFIG_UPROBE_EVENTS=y
CONFIG_DEBUG_FS=y
So enable some missed configs in loongson3_defconfig to make sure
the above configs are set after make loongson3_defconfig.

Summary of modules changes for the 5.12 merge window:
- Retire EXPORT_UNUSED_SYMBOL() and EXPORT_SYMBOL_GPL_FUTURE(). These export
types were introduced between 2006 - 2008. All the of the unused symbols have
been long removed and gpl future symbols were converted to gpl quite a long
time ago, and I don't believe these export types have been used ever since.
So, I think it should be safe to retire those export types now. (Christoph Hellwig)
- Refactor and clean up some aged code cruft in the module loader (Christoph Hellwig)
- Build {,module_}kallsyms_on_each_symbol only when livepatching is enabled, as
it is the only caller (Christoph Hellwig)
- Unexport find_module() and module_mutex and fix the last module
callers to not rely on these anymore. Make module_mutex internal to
the module loader. (Christoph Hellwig)
- Harden ELF checks on module load and validate ELF structures before checking
the module signature (Frank van der Linden)
- Fix undefined symbol warning for clang (Fangrui Song)
- Fix smatch warning (Dan Carpenter)

In the current code, we can not build under !CONFIG_NUMA and !CONFIG_SMP
on the Loongson64 platform, it seems bad for the users who just want to
use pure single core (not nosmp) to debug, so do the following things to
give them a chance:
(1) Do not select NUMA and SMP for MACH_LOONGSON64 in Kconfig, make NUMA
depends on SMP, and then just set them in the loongson3_defconfig.
(2) Move szmem() from numa.c to init.c and add prom_init_memory() under
!CONFIG_NUMA.
(3) Clean up szmem() due to the statements of case SYSTEM_RAM_LOW and
SYSTEM_RAM_HIGH are the same.
(4) Remove the useless declaration of prom_init_memory() and add the
declaration of szmem() in loongson.h to avoid build error.
