the rstack functionality:
1. Fix a KASSERT that tests for the address to be above the upward
growable stack. Typically for rstack, the faulting address can be
identical to the record end of the upward growable entry, and
very likely is on ia64. The KASSERT tested for greater than, not
greater equal, so whenever the register stack had to be grown
the assertion fired.
2. When we grow the upward growable stack entry and adjust the
unlying object, don't forget to adjust the size of the VM map.
Not doing so would trigger an assert in vm_mapzdtor().

those cylinder groups that have at least 75% of the average free
space per cylinder group for that file system are considered as
candidates for the creation of a new directory. The previous formula
for minbfree would set it to zero if the file system was more than
75% full, which allowed cylinder groups with no free space at all
to be chosen as candidates for directory creation, which resulted
in an expensive search for free blocks for each file that was
subsequently created in that directory.
Modify the calculation of minifree in the same way.
Decrease maxcontigdirs as the file system fills to decrease the
likelyhood that a cluster of directories will overflow the available
space in a cylinder group.

routine that takes a locked routing table reference and removes all
references to the entry in the various data structures. This
eliminates instances of recursive locking and also closes races
where the lock on the entry had to be dropped prior to calling
rtrequest(RTM_DELETE). This also cleans up confusion where the
caller held a reference to an entry that might have been reclaimed
(and in some cases used that reference).

to manipulate them in the free routine without having to lock the softc
structure or the free list. To get space for these flags the chunk number
is reduced to 8 bit which amounts to a maximum of 256 chunks per allocated
page. This restriction is now enforced by a CTASSERT.
