Kernel: fix some math in physical ranges
...
I allocated 1 bitmap page per 8 data pages. Bitmap page can actually
store 8*PAGE_SIZE data pages.
Also properly set last bits in bitmap. I did not care about endianness
but now we set the bits on unsigned long longs instead of bytes.

This does nothing but allocate contiguous physical and virtual memory
and map it as CacheDisable. Also memory is automatically freed RAII style.
