How to learn the size of kernel space memory


I was asked how much memory kernel space takes on a 64 bit machine by my boss... Which I was stumped over... unfortunately he's getting antsy for an answer

I searched for the last couple days for an answer how to learn this... but haven't found anything that clearly says "Linux kernel space takes xxxMb of memory"... or "xxx variable in proc shows kernel space size"

I did find something that said kernel space takes up 512 Mb in a 32 bit machine... But finding this answer for a 64 bit has been difficult

I realize kernel space is going to be dependent of the kernel build... I've found some very technical answers on it's maximum size... But I'm hoping someone could give me some guidance of the minimum kernel space requirements

Thanks!
