095f2ac443 Since if_txp doesn't contain locking or run with INTR_MPSAFE, mark 
the interface as IFF_NEEDSGIANT so if_start is run holding Giant.

Note: mutexes are initialized in the softc for this driver, but the
locking appears inadequate to allow Giant-free operation.

fc4af83ae9 Since if_nge doesn't contain locking or run with INTR_MPSAFE, mark 
the interface as IFF_NEEDSGIANT so if_start is run holding Giant.

Note: this driver does declare and occasionally reference mutexes,
but I believe not nearly enough to provide safety.

31d80b6045 Fix an off by one in the critical section clearing code. The 
code was adjusting twice for the instruction pointer indicating
the *next* instruction to execute.  The aic79xx driver had a similar
bug, but was fixed some time ago.

d990378077 Commit a work-around for a more general bug involving process state: 
check whether p_ucred is NULL or not in pfs_getattr() before
dereferencing the credential, and return ENOENT if there wasn't one.

This is a symptom of a larger problem, wherein pfind() can return
references to incompletely initialized processes, and we instead ought
to not return them, or check the process state before acting on the
process.

0164e05781 Replace the linear search in vm_map_findspace() with an O(log n) 
algorithm built into the map entry splay tree.  This replaces the
first_free hint in struct vm_map with two fields in vm_map_entry:
adj_free, the amount of free space following a map entry, and
max_free, the maximum amount of free space in the entry's subtree.
These fields make it possible to find a first-fit free region of a
given size in one pass down the tree, so O(log n) amortized using
splay trees.

This significantly reduces the overhead in vm_map_findspace() for
applications that mmap() many hundreds or thousands of regions, and
has a negligible slowdown (0.1%) on buildworld.  See, for example, the
discussion of a micro-benchmark titled "Some mmap observations
compared to Linux 2.6/OpenBSD" on -hackers in late October 2003.

OpenBSD adopted this approach in March 2002, and NetBSD added it in
November 2003, both with Red-Black trees.

* Serialize access to the sysctl routines and the notify handler
* Assert that the sx lock is held in any functions they call.
* Note that recursively calling to re-enable the hotkeys is sub-optimal.
