5937ec2e04 Reintroduce allocator designs post 
The post was split off the Heap Allocations post because it became too large. To keep the tree clean, it was then temporarily removed. This commit restores the post by reverting the removal commit.

This reverts commit 029d77ef21.

d9d204a6cd Remove superfluous adjective 
"own" may be used as an adjective, but must follow a possessive word. Rather than add "our" just remove the adjective entirely since ownership is not significant.

19f585d517 Remove x86_64 dependency update note in Paging Implementation post 
We already introduce version 0.7.0 of `x86_64` in the Testing post for some time, so it's reasonable to expect that most people use a compatible version now. Therefore, we no longer need to mention it explicitly.
