mycroft 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.

fvdl 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.

bouyer 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.

augustss 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.

christos 4d9a6e0930 - Pass the Elf32_Ehdr in the linux probe function, and use it!
Since linux binaries are (mostly) always compiled with gcc, look for
the gcc signature in the .comment section header: "\0 GCC: (GNU) ".
I've changed the probe order in kern/exec_elf.c to probe for linux ELF
binaries first and fall back to SVR4 binaries. This makes statically
linked binaries work for both linux and svr4. Note that gcc-compiled
svr4 binaries, still contain the operating system signature first and
then the GCC signature, so there is no conflict. Yes this is a hack.
