o Remove unneeded sys/types.h and netinet/in.h from the synopsis and
the example.
o We do have struct in_addr in arpa/inet.h, so no need for netinet/in.h.

reaching into the socket buffer. This prevents a number of potential
races, including dereferencing of sb_mb while unlocked leading to
a NULL pointer deref (how I found it). Potentially this might also
explain other "odd" TCP behavior on SMP boxes (although haven't
seen it reported).

1) ginode() is passed a cylinder group number and inode number. The inode
number is relative to the cg. Use this relative number rather than the
absolute inode number when searching the cg inode bitmap to see if the inode
is allocated. Using the absolute number quickly runs the check off the end
of the array and causes invalid inodes to be referenced.
2) ginode() checks the absolute indoe number to make sure that it is greater
than ROOTINO. However, the caller loops through all of the possible inode
numbers and directly passes in values that are < ROOTINO. Instead of halting
the program with an error, just return NULL.
3) When allocating new cylinder groups, growfs was initializing all of the
inodes in the group regardless of this only being required for UFS1. Not
doing this for UFS2 provides a significant performance increase.
These fixes allow growing a filesystem beyond a trivial amount and have
been tested to grow an 8GB filesystem to 1.9TB. Much more testing would
be appreciated.

state management corruption, mbuf leaks, general mbuf corruption,
and at least on i386 a first level splash damage radius that
encompasses up to about half a megabyte of the memory after
an mbuf cluster's allocation slab. In short, this has caused
instability nightmares anywhere the right kind of network traffic
is present.
When the polymorphic refcount slabs were added to UMA, the new types
were not used pervasively. In particular, the slab management
structure was turned into one for refcounts, and one for non-refcounts
(supposed to be mostly like the old slab management structure),
but the latter was almost always used through out. In general, every
access to zones with UMA_ZONE_REFCNT turned on corrupted the
"next free" slab offset offset and the refcount with each other and
with other allocations (on i386, 2 mbuf clusters per 4096 byte slab).
Fix things so that the right type is used to access refcounted zones
where it was not before. There are additional errors in gross
overestimation of padding, it seems, that would cause a large kegs
(nee zones) to be allocated when small ones would do. Unless I have
analyzed this incorrectly, it is not directly harmful.

less accuracy in the timing as the interval timer granularity is
relatively low.

(system doesn't work properly with acpi disabled) should be fixed separately.
Changes:
* Add a quirk to disable the timer
* Merge the P5A and P5A-B quirks since they appear to be based on the
