Convert shadow paging to use 32 PAE (VMX)
This changes shadow paging to use, at minimum, 32PAE
shadow page tables. This makes it possible to place
a guest using shadow paging anywhere in host physical
memory instead of just the first 4 GB
This patch adds support to VMX for this functionality:
- cr4 is read-shadowed to the shadow pager's guest cr4
- PAE is forced on
- vmx assist does not overwrite cr4 control, just masks it
- cleaner activation of passthrough PTs
Note that this is able to boot a BOCHS BIOS and a Linux guest.
It fails to boot the SEABIOS (Trap 0x8), but then that bug
is confirmed to be independent of these patches.
