Xi Wang cd00a8233a port virtio_disk to virtio spec 1.0+
The legacy interface is confusing. It's better to make virtio_disk
conform to the virtio spec. This is supported in QEMU since 4.2 by
disabling force-legacy for virtio-mmio.

l0stman 19ff379661 exec() only accepts MAXARG arguments
The terminating NULL string is already included (see sys_exec()).

l0stman 9195142959 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.

Frans Kaashoek 077323a8f0 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.
