/* Force the zero page to be part of a segment by creating a
|
|
* dummy section in the zero page.
|
|
* Limine will map the segment with the lowest vaddr value at
|
|
* 0xFFFFFFFF80000000 even if the segment has a higher vaddr.
|
|
* As such without the zero page being part of a segment, the
|
|
* kernel would be loaded at an offset from the expected
|
|
* location. As the redox kernel is not currently relocatable,
|
|
* this would result in a crash. A similar issue likely exists
|
|
* with multiboot/multiboot2 and the paddr of the segment.
