object->paging_offset has been removed - it was used to optimize a
single OBJT_SWAP collapse case yet introduced massive confusion throughout
vm_object.c. The optimization was inconsequential except for the
claim that it didn't have to allocate any memory. The optimization
has been removed.
madvise() has been fixed. The old madvise() could be made to operate
on shared objects which is a big no-no. The new one is much more careful
in what it modifies. MADV_FREE was totally broken and has now been fixed.
vm_page_rename() now automatically dirties a page, so explicit dirtying
of the page prior to calling vm_page_rename() has been removed.
about conversions of objects to OBJT_SWAP, it is done automatically

Replaced manually inserted code with inline calls for busy waiting on
pages, which also incidently fixes a potential PG_BUSY race due to
the code not running at splvm().
vm_objects no longer have a paging_offset field ( see vm/vm_object.c )

Added comments, added support for M_ASLEEP. Generally treat M_ flags
as flags instead of constants to compare against.
and the swap_pager has been completely replaced.
The new swap pager uses the new blist radix-tree based bitmap allocator
for low level swap allocation and deallocation. The new allocator
is effectively O(5) while the old one was O(N), and the new allocator
allocates all required memory at init time rather then at allocate
memory on the fly at run time.
Swap metadata is allocated in clusters and stored in a hash table,
eliminating linearly allocated structures.
Many, many features have been rewritten or added. Swap space is now
reallocated on the fly providing a poor-mans auto defragmentation of
swap space. Swap space that is no longer needed is freed on a timely
basis so no garbage collection is necessary.
Swap I/O is marked B_ASYNC and NFS has been fixed to do the right
thing with it, so NFS-based paging now has around 10x the performance
as it did before ( previously NFS enforced synchronous I/O for paging ).

Iprobe is an alpha-only system profiling suite which I'm porting from
Linux/alpha to FreeBSD.
Iprobe works by using the hardware profiling support built into
alpha cpus. In a nutshell, what Iprobe does is to setup the alpha
performance counters to sample the pc at a fairly high rate & dumps
those pc samples out to user space. Then some code runs to map the
sampled PCs to functions. You get a bit more than that (like the PSL

Instead of initializing UDMA mode, we turned it off and made sure that
it stays off by turning on the "UDMA enable by SET FEATURES" disable.
The damage was limited by bugs in cookie lookup, and suitable
initialization by some BIOSes. The cookie list has slaves before
masters, and the unit number is ignored when cookies are looked up,
so cookie lookup always finds cookies for slaves and the bug only
clobbers slaves, so the bug was harmless for common configurations
with no slaves or only non-UDMA slaves. UDMA initialization for
masters actually worked if the BIOS turns on the UDMA mode bit and
turns off the "UDMA enable by SET FEATURES" disable.

- In wb_rxeof(), if the received packet is less than MINCLSIZE bytes,
copy it to an mbuf chain so as to be more frugal in our use of mbuf
clusters.
- The Winbond chip, like the ASIX, wants the 'TX interrupt request'
bit set in the _first_ fragment of a transmitted frame, not the
last. (At least the Winbond manual states this unambiguously; too
bad I wasn't paying attention when I read it the first time.)
- Turn off the transmit threshold mechanism (initialize the threshold
to 0). This effectively puts the chip in 'store and forward' mode
which seems to cut down on transmit errors a little. It may also
reduce transmit performace a bit, but I'm willing to do that if it
means better reliability.
- Normally, the driver allocates an mbuf cluster for each receive
descriptor. This is because we have to be prepared to accomodate up to
1500 bytes (a cluster buffer can hold up to 2K). However, using up a
whole cluster buffer for a tiny packet is a bit of a waste. Also,
it seems to me that sometimes mbufs will linger in the kernel for
a while after being passed out of the driver, which means we might
drain the mbuf cluster pool. The cluster pool is smaller than the
mbuf pool in general, so we do the following: if the packet is less
that MINCLSIZE bytes, then we copy it into a small mbuf chain and
leave the mbuf cluster in place for another go-round. This saves
mbuf clusters in some cases while still allowing them to be used
for heavy traffic exchanges with lots of full-sized frames.
- The transmit descriptor has a bit in the control word which allows
the driver to request that a 'TX OK' interrupt be generated when
a frame has been completed. Sometimes, a frame can be fragmented
across several descriptors. The manual for the real DEC 21140A says
that if this happens, the 'TX interrupt request' bit is only valid
in the descriptor of the last fragment. With the ASIX chip, it seems
the 'TX interrupt request' bit is only valid in the descriptor of
the _first_ fragment. Actually, the manual contains conflicting
information, but I think it's supposed to be the first fragment.
To play it safe, set the bit in both the first and last fragment to
be sure that we get a TX OK interrupt. Without this fix, the driver
can sometimes be late in releasing mbufs from the transmit queue
after transmission.

3Com, Intel or whoever to cough up some documentation for gigabit
ethernet hardware.
Also updated RELNOTEX.TXT to mention that the SVEC PN102TX is supported
by the Macronix driver (assuming you actually have an SVEC PN102TX with
a Macronix chip on it; I tried to order a PN102TX once and got a box
labeled 'Hawking Technology PN102TX' that had a VIA Rhine board inside
it).
devices dynamically. That means,
+ only one /dev/iic or /dev/smb device for each smb/iic bus to access
+ I2C/SMB device address must be given to any ioctl
+ new devices may be plugged and accessed after boot, which was
impossible previously (device addresses were hardcoded into
the kernel)

versions of gcc and broken for current versions of egcs. The asm
here (for translate_bytes()) is now an interesting example of one
that needs to be volatile to work.
Fixed missing "memory" in the clobber list for translate_bytes().

Cleaned up the asm statement for do_cpuid() a little.

RB_CONFIG.
Now, the code should do the right thing in the following cases, when
kernel is compiled with INTRO_USERCONFIG:
* when booted without userconfig_script and without RB_CONFIG, present
intro screen, and wait for user input.
* when booted with userconfig_script and without RB_CONFIG, DON'T present
intro screen unless explicitly asked in userconfig_script, basing on
assumption that if a user loads userconfig_script, (s)he already
decided what parameters to configure. Proceed with booting.
* when booted without userconfig_script, and with RB_CONFIG, enter
configuration utility and wait for user input.
* when booted with userconfig_script, and with RB_CONFIG, execute all
commands from userconfig_script, and DON'T leave the config utility,
but wait for user input.
And finally, regardless of the combination of the above parameters,
when intro screen is invoked either first or next times, and user
chooses to go back to CLI interface, unblock the quit command.
