* 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.

* 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.

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.
