call to open(path, O_CREAT|O_EXCL|O_RDWR, 0444) should open file as

I don't know why I had added this. It doesn't seem to be a thing on

Kernel: Disable USB Mass Storage writing until I get it fixed
...
This prevented real hw from running for over 10-20 seconds. When first
disk sync happens after 10 secods, USB storage would enter faulty state
and not allow any io operations.
I have no idea what the problem is. If I don't send Reset command to the
USB device writing seems to work fine. I also don't think its part of
the Reset process either as reading works just fine.

Kernel: Add support for ATA CHS addressing and cleanup code
...
I thought that I had an PC without LBA support so I implement support
for CHS. Turns out that my ATA device detection was broken and was no
device on that port and initialize data was just garbage.
Now that I added CHS, I guess I should just keep it in :)
Both ATA read and write are now combined into a single function to avoid
code duplication.
