EISA slots to probe. This is mainly intended to allow installing the
system on an HP Netserver with an on-board AIC7xxx EISA SCSI
controller, that is sitting on EISA slot # 11.
Documentation updates explaining this hack will follow shortly.
Note that this can go away again as soon as the EISA device probing
is more intelligent about the address space clash with the PCI address
space.
2.2 candidate.

that we do allow mlock to span unallocated regions (of course, not
mlocking them.) We also allow mlocking of RO regions (which the old
code couldn't.) The restriction there is that once a RO region is
wired (mlocked), it cannot be debugged (or EVER written to.)
Under normal usage, the new mlock code will be a significant improvement
over our old stuff.
Tekram DC390W/U/F, whose config EEPROM can now be dumped, if the kernel
is built with option NCR_TEKRAM_EEPROM.
Other changes:
- add brackets to expansion of OUTB/W/L macro arguments.
- remove unused NCB structure element ns_async
- support sync. SCSI offset of 16 (instead of only 8) on 825A and 875
- correctly identify 53c810A and 53c825A chips
- preserve SCSI BIOS settings of PCI performance options
- remove (already disabled) support for NCR reset because of command timeout
- reverse order of reading of SCSI and DMA specific interrupt cause registers
- add definition of Tekram config EEPROM contents (not currently used)
to TAILQs. Fix places which referenced these for no good reason
that I can see (the references remain, but were fixed to compile
again; they are still questionable).
the profiling level in config and decide what to do in makefiles.
Makefile.i386:
Align functions to 16-byte boundaries if profiling is enabled. This
will allow a fourfold reduction in the size of the profiling buffers.
I've added an installation from optical disk drive facility.
This enables FreeBSD to be installed from an optical disk, which
may be formatted in "super floppy" style or sliced into MSDOS-FS
and UFS partitions.
Note: ncr.c should be reviewed by Stefan Esser <se@freebsd.org>
and cd.c by Joerg Wunsch <joerg@freebsd.org> before bringing this
into 2.2.

makes MADV_SEQUENTIAL much more effective. I suggest that
we start using MADV_SEQUENTIAL on system utilities that mmap
their input files, and the I/O is predominantely sequential.
Below is a test with 'cmp' on two relatively large binary files,
where the files are so large that the caching is ineffective:
+ ls -l t1.xxx t2.xxx
-rw-r--r-- 1 root wheel 65598384 Dec 10 12:13 t1.xxx
-rw-r--r-- 1 root wheel 65598384 Dec 10 12:14 t2.xxx
+ time cmp t1.xxx t2.xxx

This change is as a result of an observation made by BDE.
partition is 0, which is outside the slice unless the disk is
dangerously dedicated. There is little error checking later, and
following garbage metadata outside the slice usually caused crashes,
Empty 'a' partitions are fairly easy to create by cloning the label
for the whole disk.
Fixed a missing newline in a related error message.
type to be int so that errors can be returned.
2) Use the new SIOCSIFMTU ether_ioctl support in the few drivers that are
using ether_ioctl().
3) In if_fxp.c: treat if_bpf as a token, not as a pointer. Don't bother
testing for FXP_NTXSEG being reached in fxp_start()...just check for
non-NULL 'm'. Change fxp_ioctl() to use ether_ioctl().
ACTUALLY_LKM_NOT_KERNEL until the real fix comes through. Whatever
flag that is used to indicate building LKMs will have be be substituted
in the future. This allows proper selection of the usage of the
efficient, single instruction in the kernel, but alas, doesn't allow
for use in userland or LKMs :-(. Them's the breaks!!!
with one of the following (I486_CPU,I586_CPU,I686_CPU) so it can take
advantage of the very quick bswap insn. This keeps LKMs from being
built to take advantage of the insn, but also makes sure that the LKMs
can be run on all CPUs. (The LKMs don't pick up the CPU options :-( ).
that map entries are coalesced when appropriate. Also, conditionalize
some code that is currently not used in vm_map_insert. This mod
has been added to eliminate unnecessary map entries in buffer map.
Additionally, there were some cases where map coalescing could be done
when it shouldn't. That problem has been resolved.
