5c7e0ada43 Use a pool cache for L1 PT pages. When we can allocate a cached, 
constructed L1 PT page, this saves us from having to copy the kernel
L1 PTEs into the user L1 PT page at fork time (it's already set up).

A simple test shows a 1 second improvement of a rapid fork/exit operation
10000 times on a 533MHz 21164A (12s to 11s).

b21b6272fa Fix PR 11000: The esp driver needs two longwords in DAFB register space to 
implement pseudo-DMA transfers with the SCSI controller.  This caused our
match to fail when we couldn't map the entire DAFB register/control space
for our own use.  Instead, we map only (about) what we will need in two
separate regions.

As a consequence we no longer do Turbo SCSI configuration here; indeed, it
may have caused us trouble later on if we actually changed the values
stored in those registers in the esp driver.
