[dmidecode] [PATCH 1/2] dmidecode: Use the most appropriate unit for cache size

[Jean Delvare]

As newer CPUs have larger and larger cache, using kB to represent the
cache size is getting less convenient. Reuse the same function we have
for system memory size so that large units will be used as
appropriate. For example, a cache size reported as "20 MB" looks nicer
than as "20480 kB".
