Previously it was possible for fragmentation to occur and as a result
certain allocations would have a linear virtual address space but not a
linear physical address space. This is bad since a lot of calls to
kmalloc_align rely upon both being linear, it has now been changed such
that all allocations done by kmalloc_align now guarantee this mapping
holds for both virtual and physical addresses.
It was due to oversight and sheer luck that this had been working for so
long.

Having min/max be functions was a stupid decision in the first place

Now it avoids waiting for completion if possible and can instead batch
commands.

Instead of having to store state in variables functions are called to
check the object directly.

This also changes the ext2 filesystem so it will now write to the file
it mounted. Currently the file mounted is /dev/sda which points to a
SATA drive.
|
|
It will now also create a corresponding /dev/sd* device for each
detected SATA drive. The filesystem still writes using the ATA driver.
This should be fixed soon.

This caused the tables to be cloned instead of having the pointer copied
on the new page directory creations.
This is just a solution to the symptom of having a bad design for
memory managment. Maybe I will figure out something better.

Currently certain parts of the code are taken from osdev wiki as there
seems to be very little documentation that I can find on how H2D FIS is
structured. Those parts, especially some of the uglier parts of the
example code will be rewritten/changed.
