The nesting rules of macros are different, which required some changes.
Use __CONCAT(x,y) instead of /**/.
Redo some comments to use /* */ rather than "# comment" because the ansi
cpp cares about those, and also cares about quote matching.

This means that any cpp fatal errors will now be detected, as well as

to be allocated at boot time. This is an expensive option, as they
consume physical ram and are not pageable etc. In certain situations,
this kind of option is quite useful, especially for news servers that
access a large number of directories at random and torture the name cache.
Defining 5000 or 10000 extra vnodes should cut down the amount of vnode
recycling somewhat, which should allow better name and directory caching
etc.
This is a "your mileage may vary" option, with no real indication of
what works best for your machine except trial and error. Too many will
cost you ram that you could otherwise use for disk buffers etc.
This is based on something John Dyson mentioned to me a while ago.

case where blocking can occur, thereby giving other process's a chance
to modify the queue where a page resides. This could cause numerous
process and system failures.
that the datastructures needed to support the swap pager can take
enough space to fully deplete system memory, and cause a deadlock.
This change keeps large objects from being filled with dirty pages
without the appropriate swap pager datastructures. Right now,
default objects greater than 1/4 the size of available system memory
are converted to swap objects, thereby eliminating the risk of deadlock.

Wide/Narrow boot problems that have been reported since this bug

a condition when blocking can occur, and the daemon did not check properly
for a page remaining on the expected queue. Additionally, the inactive
target was being set much too large for small memory machines. It is now
being calculated based upon the amount of user memory available on every
pageout daemon run. Another problem was that if memory was very low, the
pageout daemon could fail repeatedly to traverse the inactive queue.
problem. BY MISTAKE, the vm_page_unqueue (or equiv) was removed from the
vm_fault code. Really bad things appear to happen if a page is on a queue
while it is being faulted.

If you really have a desperate need to link or unlink a directory, you

If COMPAT_IPFW is not defined, or if it is defined to 1, enable;

This means that these changes actually have no effect on anyone at the

In the future, the `not defined' part of the hack should be eliminated,

comparing the PTD pointers, they needed to be masked by PG_FRAME, and
they weren't. Also, the "improved" non-386 code wasn't really an
improvement, so I simplified and fixed the code. This might have
caused some of the panics caused by the VM megacommit.

Remove all Ultra settings except for the top three that are documented
