+Subject: [PATCH] json_print: Fix hidden 64-bit type promotion
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+print_uint() will silently promote its variable type to uint64_t, but there
+is nothing that ensures that the format string specifier passed along with
+it fits (and the function name suggest to pass "%u").
+
+Fix this by changing print_uint() to use a native 'unsigned int' type, and
+introduce a separate print_u64() function for printing 64-bit values. All
+call sites that were actually printing 64-bit values using print_uint() are
+converted to use print_u64() instead.
+
+Since print_int() was already using native int types, just add a
+print_s64() to match, but don't convert any call sites.
