This makes it possible to change the sysctl tree at runtime.
* Change KLD to find and register any sysctl nodes contained in the loaded
file and to unregister them when the file is unloaded.

Seems to solve a problem with a mouse not responding to movements in the
X direction. Problem description is still rather vague and solution is
not exactly clear. Problem might be a compiler optimisation.

it more readable, reduce the size of the code, and optimize the branch
path caching capabilities that most modern processors have.
free swap space out from under a busy page. This is not legal because
the swap may be reallocated and I/O issued while I/O is still in
progress on the same swap page from the madvise()'d object. This bug
could only occur under extreme paging conditions but might not cause
an error until much later. As a side-benefit, madvise() is now even
smaller.
This will trigger inserted()) to be called twice which confuses pccardd.
Add code to not process pcicitr())'s when in the middle of a resume

programs, including msdos, set PSL_NT in probes for old cpu types,
although PSL_NT doesn't do anything useful in vm86 or real mode.
PSL_NT is even less useful in the signal handlers. It just causes
T_TSSFLT faults on return from syscalls made by the handlers.
These faults are fixed up lazily so that Xsyscall() doesn't have
to be slowed down to prevent them. The fault handler recently
started complaining about these faults occurring "with interrupts
disabled". It should not have, but the complaints pointed to this
bug.

the API for freeing up cnp's. This cleanup should not effect nominal
operation one way or the other since NFS VOPs just happen to be called
with flags that match what it actually does to the NAMEI components it
gets. Still, if an NFS error occured, there was probably some memory
leakage of NAMEI components with certain NFS VOP ops.

As of now, I declare madvise() on OBJT_DEFAULT/OBJT_SWAP objects to be

Now should be able to report speed for cards using NatSemi PHY.

In vm_object_madvise(), remove calll to vm_page_cache() in MADV_FREE

mark the page as clean and destroy any swap backing store.

3c905B, the RX and TX reset commands also reset the cyclone chip's internal
PHY, which causes it to restart its autonegotiation session. This takes a
second or two to complete, which makes the interface seem to stop responding
for a few seconds every time you do something that reinitializes it.
Issuing the RX and TX resets on the older 3c905 boomerang adapters doesn't
cause any delay because the boomerang chip requires an external PHY.
This should fix the problem where people doing network installs via 3c905B
cards experience a delay after the interface is first initialized, among
other things.
