d0b1ee0833 * Optimize pmap_{zero,copy}_page4m() a bit by pre-computing the PTE addresses 
of the reserved KVAs (vpage[]) used by these routines. This avoids the
  context switching in there.

* In pmap_redzone(), remove the first kernel address (at KERNBASE) from
  the kernel maps instead of just turning off the PTE `valid' bits.
  The latter doesn't create a "red zone" at all, but causes the VM to
  allocate a new page if the red zone is touched.

665c7aa080 * Implement a private page table storage allocator for SRMMUs. It provides 
uncached (if needed) chunks of memory of the two sizes (256 and 1024
  bytes) that the SRMMU ever needs.

* Change pmap_changeprot4m() so that is does not rely setpte4m() because
  setpte4m() cannot be used for anything other than VAs that are in the
  pmap associated with the current context.
  In the same vain, make sure that kvm_uncache() switches to context 0.

msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.

New bootblocks without the hard-coded KERNBASE reference will be assigned
a new magic number.

with the console (RB_ASK!) by calling cngetc(), which goes off polling

6616d47838 - Change audio_hw_if a little: set_param now sets the play and record modes 
at the same time instead by using two different calls.  This enables
  it to check more easily if the combined mode is all right.
- Improve the error checking in audio.c.
- Add a new audio property, AUDIO_PROP_INDEPENDENT, show if the
  play and record settings are independent.
- Fix some buglets in audio.c.

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.
