TheOddGarlic 9329059510 IDE: Add LBA28 addressing support
LBA28 is obsolete at this point, but we prefer to use it over LBA48
whenever we can because LBA28 is faster.

TheOddGarlic 8a1c77db58 IDE: Rename PiixIde to PciIde, use it for all IDE controllers
If the controller is not a known PCI IDE controller, then we warn about
the controller during PCI device discovery. :^)

TheOddGarlic 91c1783b99 vfs+ext2: initial FsNode::read() implementation
The VFS side of things for read() should be done, however due to my
limited ext2 knowledge, I've not implemented partially reading a file,
and in this state only full files can be read.

FsNode::close() will instead become a method that takes a closes a file descriptor, while release() will close the whole VFS node.

Erin cd8e6e4b3b So I have two news for you. One good and one bad.
We have async, but we got rid of the preëmptive sched... wait, that's two good news, anyways, have a nice day.
