hw/display/milkymist-tmu2: Move inlined code from header to source
Move the complexity of milkymist_tmu2_create() into the
source file. Doing so we avoid to include the X11/OpenGL
headers in all LM32 devices, and we also avoid the duplicate
declaration of glx_fbconfig_attr[] (it is already declared
in hw/display/milkymist-tmu2.c).
Since TYPE_MILKYMIST_TMU2 is now accessible, use it.

configure: LM32 Milkymist Texture Mapping Unit (tmu2) also depends of X11
Commit 5f9b1e35060b8 remove the dependency between OpenGL and X11.
However the milkymist-tmu2 device do require X11.
When using SDL, the configure script sets need_x11=yes, so the X11
flags are populated to the makefiles.
When building without SDL, X11 is not pulled and populated, leading
to a link failure:

usb: assign unique serial numbers to hid devices
Windows guests have trouble dealing with usb devices having identical
serial numbers. So, assign unique serial numbers to usb hid devices.
All other usb devices have this already.
In the past the fixed serial number has been used to indicate working
remote setup to linux guests. Here is a bit of history:
* First there was nothing.
* Then I added a rule to udev checking for serial == 42.
(this is in rhel-6).
* Then systemd + udev merged.
* Then I changed the rule to check for serial != 1 instead, so we can
use any serial but "1" which is the one the old broken devices had
(this is in rhel-7). March 2014 in upstream systemd.
* Then all usb power management rules where dropped from systemd (June
2015). Which I figured today (Sept 2018), after wondering that the
rules are gone in fedora 28.
So, three years ago the serial number check was dropped upstream, yet I
hav't seen a single report about autosuspend issues (or cpu usage for
usb emulation going up, which is the typical symtom).
So I figured I can stop worring that changing the serial number will
break things and just do it.
And even if it turns out autosuspend is still an issue: I think
meanwhile we can really stop worrying about guests running in old qemu
versions with broken usb suspend (fixed in 0.13 !). If needed we can
enable autosuspend unconditionally in guests.

the two clusters may have different views of physical

present or absent).
We put the cluster number in the high 8 bits of the
TB cflags. This gives us up to 256 clusters, which should
be enough for anybody. If we ever need more, or need
more bits in cflags for other purposes, we could make

qom/cpu: Add cluster_index to CPUState
For TCG we want to distinguish which cluster a CPU is in, and
we need to do it quickly. Cache the cluster index in the CPUState
struct, by having the cluster object set cpu->cluster_index for
each CPU child when it is realized.
This means that board/SoC code must add all CPUs to the cluster
before realizing the cluster object. Regrettably QOM provides no
way to prevent adding children to a realized object and no way for
the parent to be notified when a new child is added to it, so
we don't have any way to enforce/assert this constraint; all
we can do is document it in a comment. We can at least put in a
check that the cluster contains at least one CPU, which should
catch the typical cases of "realized cluster too early" or
"forgot to parent the CPUs into it".
The restriction on how many clusters can exist in the system
is imposed by TCG code which will be added in a subsequent commit,
but the check to enforce it in cluster.c fits better in this one.

a failure of the rest of the regex to match. Switch to "/\*\*?+"
which uses what perlre(1) calls the "possessive" quantifier form:
this means that if it matches the "/**" string it will not later
backtrack to matching just the "/*" prefix.
The other end of the regex is also wrong: it is attempting
to check for "/* or /** followed by something that isn't

whitespace. This is less significant but means that a line
with just a comment-starter followed by trailing whitespace
will generate an incorrect warning about block comment style

[PMM: fix block comment style] Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
This patch introduced two calls to get_pmceid() during CPU
initialization - one each for PMCEID0 and PMCEID1. In addition to
building the register values, get_pmceid() clears an internal array
mapping event numbers to their implementations (supported_event_map)
before rebuilding it. This is an optimization since much of the logic is
shared. However, since it was called twice, the contents of
supported_event_map reflect only the events in PMCEID1 (the second call
to get_pmceid()).
Fix this bug by moving the initialization of PMCEID0 and PMCEID1 back
into a single function call, and name it more appropriately since it is
doing more than simply generating the contents of the PMCEID[01]
registers.

exec.c: Use correct attrs in cpu_memory_rw_debug()
In the softmmu version of cpu_memory_rw_debug(), we ask the
CPU for the attributes to use for the virtual memory access,
and we correctly use those to identify the address space
index. However, we were not passing them in to the
address_space_write_rom() and address_space_rw() functions.
The effect of this was that a memory access from the gdbstub
to a device which had behaviour that was sensitive to the
memory attributes (such as some ARMv8M NVIC registers) was
incorrectly always performed as if non-secure, rather than
using the right security state for the CPU's current state.

When both are 0, the function now returns the first attached CPU,

When PID is specified but TID is 0, the function returns the first CPU
