Subject: Re: x86_64: wrong DirectMap kB

Hey,

 Interesting. I am able to reproduce the same problem as you using mem=700M, which shows: 

DirectMap4k:        4096 kB
DirectMap2M:    18446744073709547520 kB

However, it appears to be normal without the boot parameter:

DirectMap4k:        4096 kB
DirectMap2M:    15708160 kB

What does your output looks like with the full amount on 3.6?
