Odd meminfo 2.4.14

[Mike Black]

On 2.4.14 (upgraded from 2.4.10) first time I've seen this (I run vmstat all
the time).

        total:    used:    free:  shared: buffers:  cached:

I've got this exact same kernel on two other machines and they don't show
the funky cache #'s (yet).

I see in proc_misc.c that cache is printed with B(pg_size) in the first line
whereas it's printed with K(pg_size - swapper_space.nrpages) on the
"Cached:" line.
Both of them are wrong so it looks like pg_size is hosed somehow.

Also...pg_size is:
pg_size = atomic_read(&page_cache_size) - i.bufferram ;

What does pg_size have to do with bufferram????
