[Qemu-devel] [PATCH] misc: don't use hwaddr as a type in trace events

["Daniel P. Berrangé" <berrange@redhat.com>]

Use types that are defined by QEMU in trace events caused build failures
for the UST trace backend:

  In file included from trace-ust-all.c:13:0:
  trace-ust-all.h:11844:206: error: unknown type name ‘hwaddr’

It only knows about C built-in types, and any types that are pulled in
from includs of qemu-common.h and lttng/tracepoint.h. This does not
include the 'hwaddr' type, so replace it with a uint64_t which is what
exec/hwaddr.h defines 'hwaddr' as. This fixes the build failure
introduced by

For future work it might be good to have tracetool whitelist the
permitted data types that can be safely used in trace events...
