Vnode freelist handling has been hauled over. Vnodes are only on the
freelist if nobody care about them.
-The kernel provides assistance to getcwd() if possible.
+The kernel provides assistance to getcwd() from data stored in the name
+cache if possible.
+
+An interrupt driven configuration hook mechanism has been implemented.
+This allows drivers to postpone part of their configuration until after
+interrupts are fully enabled. This speeds booting because busy-waiting
+is avoided for things like sub device probing (eg: SCSI bus probes).
+
+The timeout(9) system in the kernel has been overhauled. This gives
+O(1) insertion and removal of callouts and an O(hash chain length)
+amount of work to be performed in softclock. The original paper is at:

+Changes in driver buffer queuing to deal with ordered transactions. This
+is intended for sequencing data and metadata writes in the filesystem code
+once fully supported.
+
+EISA Shared interrupts are now supported, working with the framework
+originally for supporting PCI shared interrupts.
