* for a bootloader as small and simple as possible. Instead of worring about
* unneccesary data copies, node scans, etc, I just optimized for the known
* common case, a kernel, which looks like:
- * (1) most pages are 4096 bytes
+ * (1) most pages are 4096 bytes
* (2) version numbers are somewhat sorted in acsending order
* (3) multiple compressed blocks making up one page is uncommon
