freebsd-meminfo on amd64

[Rong-En Fan <rafan (at) infor.org>]

Hi,

I'm running 4.2.0 and found there is a problem of freebsd-meminfo
on amd64. I have 2G memory and got the following:

Total:2033
Free:31335125091216

Change the following line

        printf("Free:%lu\n", (pagesize / 1024)*(vmdata.t_free / 1024));

to

        printf("Free:%lu\n", ((int)pagesize / 1024)*(vmdata.t_free / 1024));

Then it works as expected.

BTW, I think the logical of free memory can be changed as in

http://people.freebsd.org/~rse/dist/freebsd-memory

In short, logical free memory are inactive + cache + free.

BTW, I'm working on FreeBSD port for Hobbit server. If you are using
Hobbit on FreeBSD and want to test it, please drop me a line privately.

Thanks,
