This reverts commit c031b41b783cc99c0bd5aac7d14c1d6e34520397.
Adding the ACPI parser from GRUB was a mistake as its license
conflicts with the one used by the legacy Linux drivers. Furthermore,
adding support for ACPI to the kernel violates the minimality
principle.

Previously, we used contiguous page directories four pages in length
when using PAE. To prevent physical memory fragmentation, we need to
use virtual memory for objects spanning multiple pages. Virtual
kernel memory, however, is a scarce commodity.

module structure, module data and module strings, set
biosmem_register_boot_data temporary parameter to TRUE.

The old assumption that all physical memory is directly mapped in
kernel space is about to go away. Those variables are directly linked
to that assumption.

when computing their length.

Import upstream biosmem changes and adjust for local modifications.
Specifically, this change makes the biosmem module reliably track all
boot data by storing their addresses in a sorted array. This allows

Import upstream biosmem and vm_page changes, and adjust for local
modifications.
Specifically, the biosmem module was mistakenly loading physical
segments that did not clip with the heap as completely available.
This change makes it load them as completely unavailable during

loaded.

In order to increase the amount of memory available for kernel objects,
without reducing the amount of memory available for user processes,
a new allocation strategy is introduced in this change.
Instead of allocating kernel objects out of kernel virtual memory,
the slab allocator directly uses the direct mapping of physical
memory as its backend. This largely increases the kernel heap, and
removes the need for address translation updates.
In order to allow this strategy, an assumption made by the interrupt
code had to be removed. In addition, kernel stacks are now also
allocated directly from the physical allocator.

This change replaces the historical page allocator with a buddy allocator
implemented in vm/vm_page.c. This allocator allows easy contiguous allocations
and also manages memory inside segments. In a future change, these segments
will be used to service requests with special constraints, such as "usable
for 16-bits DMA" or "must be part of the direct physical mapping".

Do not call pmap_unmap_page_zero.

zero may break some BIOS functions.
