Merge remote-tracking branch 'remotes/stsquad/tags/pull-testing-fixes-100920-1' into staging

Various misc and testing fixes:

  - Expand CODING_STYLE.rst a little more
  - usb-host build fix
  - allow check-softfloat unit tests without TCG
  - simplify mips imm_branch so compiler isn't confused
  - mark ppc64abi32 for deprecation
  - more compiler soothing in pch_rev_id
  - allow acceptance to skip missing binaries
  - more a bunch of plugins to contrib

-When wrapping standard library functions, use the prefix ``qemu_`` to alert
-readers that they are seeing a wrapped version; otherwise avoid this prefix.
+Variable Naming Conventions
+---------------------------
+
+A number of short naming conventions exist for variables that use
+common QEMU types. For example, the architecture independent CPUState
+is often held as a ``cs`` pointer variable, whereas the concrete
+CPUArchState is usually held in a pointer called ``env``.
+
+Likewise, in device emulation code the common DeviceState is usually
+called ``dev``.
+
+Function Naming Conventions
+---------------------------
+
+Wrapped version of standard library or GLib functions use a ``qemu_``
+prefix to alert readers that they are seeing a wrapped version, for
+example ``qemu_strtol`` or ``qemu_mutex_lock``.  Other utility functions
+that are widely called from across the codebase should not have any
+prefix, for example ``pstrcpy`` or bit manipulation functions such as
+``find_first_bit``.
+
+The ``qemu_`` prefix is also used for functions that modify global
+emulator state, for example ``qemu_add_vm_change_state_handler``.
+However, if there is an obvious subsystem-specific prefix it should be
+used instead.
+
+Public functions from a file or subsystem (declared in headers) tend
+to have a consistent prefix to show where they came from. For example,
+``tlb_`` for functions from ``cputlb.c`` or ``cpu_`` for functions
+from cpus.c.
+
+If there are two versions of a function to be called with or without a
+lock held, the function that expects the lock to be already held
+usually uses the suffix ``_locked``.

+Example Plugins
+===============
+
+There are a number of plugins included with QEMU and you are
+encouraged to contribute your own plugins plugins upstream. There is a
+`contrib/plugins` directory where they can go.
+
+- tests/plugins
+
+These are some basic plugins that are used to test and exercise the
+API during the `make check-tcg` target.
+
+- contrib/plugins/hotblocks.c
+
+The hotblocks plugin allows you to examine the where hot paths of
+execution are in your program. Once the program has finished you will
+get a sorted list of blocks reporting the starting PC, translation
+count, number of instructions and execution count. This will work best
+with linux-user execution as system emulation tends to generate
+re-translations as blocks from different programs get swapped in and
+out of system memory.
+
+If your program is single-threaded you can use the `inline` option for
+slightly faster (but not thread safe) counters.
+
+Example::
+
+  ./aarch64-linux-user/qemu-aarch64 \
+    -plugin contrib/plugins/libhotblocks.so -d plugin \
+    ./tests/tcg/aarch64-linux-user/sha1

+This is an instruction classifier so can be used to count different
+types of instructions. It has a number of options to refine which get
+counted. You can give an argument for a class of instructions to break
+it down fully, so for example to see all the system registers
+accesses::
+
+  ./aarch64-softmmu/qemu-system-aarch64 $(QEMU_ARGS) \
+    -append "root=/dev/sda2 systemd.unit=benchmark.service" \
+    -smp 4 -plugin ./contrib/plugins/libhowvec.so,arg=sreg -d plugin

+This is a debugging tool for developers who want to find out when and
+where execution diverges after a subtle change to TCG code generation.
+It is not an exact science and results are likely to be mixed once
+asynchronous events are introduced. While the use of -icount can
+introduce determinism to the execution flow it doesn't always follow
+the translation sequence will be exactly the same. Typically this is
+caused by a timer firing to service the GUI causing a block to end
+early. However in some cases it has proved to be useful in pointing
+people at roughly where execution diverges. The only argument you need
+for the plugin is a path for the socket the two instances will
+communicate over::
+
+
+  ./sparc-softmmu/qemu-system-sparc -monitor none -parallel none \
+    -net none -M SS-20 -m 256 -kernel day11/zImage.elf \
+    -plugin ./contrib/plugins/liblockstep.so,arg=lockstep-sparc.sock \
+  -d plugin,nochain
+
+which will eventually report::
