523d84775a Emulate mremap(2) by returning ENOMEM for now. This should be sufficient for 
realloc(3) and other uses.  From Matthias Scheler in PR 3920.

d6e5e295fa Signal error when getting a 64 bit offset cookie that can't be stored 
in 32 bits. Provide an error message to the user, and return EINVAL.
Also, pay attention to the EOF flag from VOP_READDIR. Correct a
misspell in a panic message.

1cd83a5971 Fix "missing entries" bug when reading large directories: When reading a 
directory and running out of space in the dest buffer, off should point to the
current entry (which was not saved) and not to the next.
I discovered this bug using linux and SunOS emulation over NFS, but seems to
affect other emulations as well.

9745684ebe Changes to the sudio system: 
- It is now possible to handle devices that want "looping" DMA,
    e.g. the SoundBlaster correctly.  The WSS and SB drivers use this.
    To do this several new methods were introduced in audio_hw_if.
  - Different silence handling (forced by previous change).
  - The audio driver can now be mmap()-ed, but due to problems in
    the VM system only for writing for now.
  - The OSS (Linux) audio emulation takes advantage of some of the
    new features.
