The point of writing a macro embedded in a 'do { ... } while (0)'
loop (particularly if the macro has multiple statements or would
otherwise end with an 'if' statement) is so that the macro can be
used as a drop-in statement with the caller supplying the
trailing ';'. Although our coding style frowns on brace-less 'if':
if (cond)
statement;
else
something else;
that is the classic case where failure to use do/while(0) wrapping
would cause the 'else' to pair with any embedded 'if' in the macro
rather than the intended outer 'if'. But conversely, if the macro
includes an embedded ';', then the same brace-less coding style
would now have two statements, making the 'else' a syntax error
rather than pairing with the outer 'if'. Thus, even though our
coding style with required braces is not impacted, ending a macro
with ';' makes our code harder to port to projects that use
brace-less styles.
The change should have no semantic impact. I was not able to
fully compile-test all of the changes (as some of them are
examples of the ugly bit-rotting debug print statements that are
completely elided by default, and I didn't want to recompile
with the necessary -D witnesses - cleaning those up is left as a
bite-sized task for another day); I did, however, audit that for
all files touched, all callers of the changed macros DID supply
a trailing ';' at the callsite, and did not appear to be used
as part of a brace-less conditional.

Commit "3d90c62548 vga: stop passing pointers to vga_draw_line*
functions" is incomplete. It doesn't handle the case that the vga
rendering code tries to create a shared surface, i.e. a pixman image
backed by vga video memory. That can not work in case the guest display
wraps from end of video memory to the start. So force shadowing in that
case. Also adjust the snapshot region calculation.
Can trigger with cirrus only, when programming vbe modes using the bochs
api (stdvga, also qxl and virtio-vga in vga compat mode) wrap arounds
can't happen.

* dec-21154-p2p-bridge

* pcie-port: all non-abstract subtypes of pcie-port are already

megasas_register_types(), according to information in the

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.
