Since this is the same pattern in all files touched, it can be generalized:
qemu-common.h:
#define QEMU_DPRINTF(cond,pfx,fmt,...) \
do { \
if (cond) {
fprintf(stderr, pfx # ": " fmt, ## __VA_ARGS__); \
} \
while(0)
This file (and other):
#ifndef DEBUG_I82374
#define DEBUG_I82374 0
#endif
#define DPRINTF(fmt, ...) QEMU_DPRINTF(DEBUG_I82374, "I82374", fmt, ##
__VA_ARGS__)
which is just 4 lines per file.
FWIW.
