loader: want mechanism to avoid RA with bcache
While we have mechanisms in place to protect ourselves against the read behind the disk end, there is still one corner case. As the GPT partition table has backup table at the end of the disk, and we yet do not know the size of the disk (if the wrong size is provided by the firmware/bios), we need to limit the reads to avoid read ahead in such case.
Discovered the problem with testing 32-bit UEFI and noticed the read failure messages.
