kdb: kdb_support: Fix debugging information problem
There are several common patterns.
0:
kdb_printf("...",...);
which is the normal one.
1:
kdb_printf("%s: "...,__func__,...)
We could improve '1' to this :
#define kdb_func_printf(format, args...) \
kdb_printf("%s: " format, __func__, ## args)
2:
if(KDB_DEBUG(AR))
kdb_printf("%s "...,__func__,...);
We could improve '2' to this :
#define kdb_dbg_printf(mask, format, args...) \
do { \
if (KDB_DEBUG(mask)) \
kdb_func_printf(format, ## args); \
} while (0)
In addition, we changed the format code of size_t to %zu.
