Side note: the people who actually care about "my vmalloc area is too
full, what's up?" would use /proc/vmallocinfo anyway, since that's
what shows things like fragmentation etc.

So I'm just talking about removing the /proc/meminfo part. First try
to remove it *all*, and if there is some script that hollers because
it wants to parse them, print out the values as zero.
