exec() only accepts MAXARG arguments
...
The terminating NULL string is already included (see sys_exec()).

Assert that the size in mappages() is always positive
...
If va % PGSIZE == 0 and size == 0, we have last < a at the start of
the loop so we might never terminate. That being said, this
particular case couldn't be triggered for now.

Rename icache to itable
...
The inode cache isn't really a cache. The main purpose of it is to
allow for synchronization (locking individual inodes), providing
long-lived references to inodes, and ensuring that there is only inode
in memory.
