This patch is created by the following:
check that we have a problem
> find . -name trace-events | xargs grep '%#' | wc -l
56
check that there are no cases with additional printf flags before '#'
> find . -name trace-events | xargs grep "%[-+ 0'I]+#" | wc -l
0
check that there are no wrong usage of '#' and '0x' together
> find . -name trace-events | xargs grep '0x%#' | wc -l

fix the problem
> find . -name trace-events | xargs sed -i 's/%#/0x%/g'
[Eric Blake noted that xargs grep '%[-+ 0'I]+#' should be xargs grep
"%[-+ 0'I]+#" instead so the shell quoting is correct.

The sm501 device uses vmstate_register_ram_global() to register its
memory region for migration. This means it gets a name that is
assumed to be global to the whole system, which in turn means that if
you create two of the device we assert because of the duplication:
qemu-system-ppc -device sm501 -device sm501
RAMBlock "sm501.local" already registered, abort!
Aborted (core dumped)
Changing this to just use memory_region_init_ram()'s automatic
registration of the memory region with a device-local name fixes
this. The downside is that it breaks migration compatibility, but
luckily we only added migration support to this device in the 2.10
release cycle so we haven't released a QEMU version with the broken
implementation.

but it's actually the best we can do. Especially in these cases a verbose

Let's introduce infrastructure for specifying a error hint to be used if
equal check fails. Let's do this by adding a parameter to the _EQUAL
macros called _err_hint. Also change all current users to pass NULL as
last parameter so nothing changes for them.

We only emulate the sysbus device in its default LE mode and PCI is LE
as well so specify this for registers and framebuffer memory.
Note that though the Linux kernel driver has code which claims to
handle both big and little endian, it is obviously bogus for 16 bit
and cannot be trusted as a source of information on the framebuffer
pixel format. This is our best guess about device behaviour based on
the specs and testing with MorphOS that is known to work on real HW.

The vga code clears the dirty bits *after* reading the framebuffer
memory. So if the guest framebuffer updates hits the race window
between vga reading the framebuffer and vga clearing the dirty bits
vga will miss that update
Fix it by using the new memory_region_copy_and_clear_dirty()
memory_region_copy_get_dirty() functions. That way we clear the
dirty bitmap before reading the framebuffer. Any guest display
updates happening in parallel will be properly tracked in the
dirty bitmap then and the next display refresh will pick them up.
Problem triggers with mttcg only. Before mttcg was merged tcg
never ran in parallel to vga emulation. Using kvm will hide the
problem too, due to qemu operating on a userspace copy of the
kernel's dirty bitmap.
