Huge pages support for x86 #1016

Open NIMogen opened 1 year ago

PR as requested. Higher level page table entries (such as p2) are always marked as used for some reason. Just a draft as this is a WIP and not actually ready yet.

As discussed on discord, I can reproduce the error, which is caused by not using a range of pages and frames that are properly aligned to a 2MiB boundary.
