Log Message:
- Do away with separate pool_cache for some kernel objects that have no special
requirements and use the general purpose allocator instead. On one of my
test systems this makes for a small (~1%) but repeatable reduction in system
time during builds presumably because it decreases the kernel's cache /
memory bandwidth footprint a little.
- vfs_lockf: cache a pointer to the uidinfo and put mutex in the data segment.
