1240469 Incorporate UFS bmap cache functionality to improve NFS write
	performance

This patch is a point patch for the Netra NFS Server's kernel changes.
The kernel changes to the Netra NFS server include:

        o Changes to UFS filesystem kernel module and UFS utilities
          (fsck(1M), mkfs(1M), newfs(1M), tunefs(1M)). These changes are
          required for increasing NFS Server throughput and minimizing the
          NFS server response times.

        o Changes to the Sun4u kernel startup code. These include changes
          to allocate (PROM) retained memory to be used as stable memory in
          lieu of NVRAM for NFS write acceleration. Hooks have also been
          provided to dump the stable memory to specially assigned
          disk partition, in the event of a system crash or panic.

        o Changes to rcS and mountall scripts to automatically repair
          filesystems which need repairing at startup time. This change is
          motivated by the need to provide minimal operator intervention.

        o Integrate bug-fixes from S2.5 SMCC 1/96 release for the Colossus
	  Lite driver.  These bug-fixes are required for reliable operation
	  of the FEPS driver.
