kernel - Implement segment pmap optimizations for x86-64 (1)
* Relax the mmap() size requirement when auto-aligning the address.
Also auto-align to a segment boundary if the size is > 16 * SEG_SIZE.
It previously only allowed size to be an exact multiple of SEG_SIZE.
* Some pages at the end won't be optimized, but the bulk of the mmap()
will be.
