relocation is not sufficient for ELF relocatable object format
modules, since accessing the module metadata involves following
pointers between different ELF sections.
This allows kldxref to correctly build linker.hints on the amd64

to get used to the fact that Perl is no longer part of the base system.
It is practically impossible to install any useful package and not get
Perl automatically pulled in as a dependency. So the typical user will
get their Perl.
This change greatly reduces the amount of manual labor in building the
miniinst.iso in release building.
Centralize the fdctl_wr() function by adding the offset in
the resource to the softc structure.
Bugfix: Read the drive-change signal from the correct place:
same place as the ctl register.
Remove the cdevsw{} related code and implement a GEOM class.
Ditch the state-engine and park a thread on each controller
to service the queue.
Make the interrupt FAST & MPSAFE since it is just a simple
wakeup(9) call.
Rely on a per controller mutex to protect the bioqueues.
Grab GEOMs topology lock when we have to and Giant when
ISADMA needs it. Since all access to the hardware is
isolated in the per controller thread, the rest of the
driver is lock & Giant free.
Create a per-drive queue where requests are parked while
the motor spins up. When the motor is running the requests
are purged to the per controller queue. This allows
requests to other drives to be serviced during spin-up.
Only setup the motor-off timeout when we finish the last
request on the queue and cancel it when a new request
arrives. This fixes the bug in the old code where the motor
turned off while we were still retrying a request.
Make the "drive-change" work reliably. Probe the drive on
first opens. Probe with a recal and a seek to cyl=1 to
reset the drive change line and check again to see if we
have a media.
When we see the media disappear we destroy the geom provider,
create a new one, and flag that autodetection should happen
next time we see a media (unless a specific format is configured).
Add sysctl tunables for a lot of drive related parameters.
If you spend a lot of time waiting for floppies you can
grab the i82078 pdf from Intels web-page and try tuning
these.
Add sysctl debug.fdc.debugflags which will enable various
kinds of debugging printfs.
Add central definitions of our well known floppy formats.
Simplify datastructures for autoselection of format and
call the code at the right times.
Bugfix: Remove at least one piece of code which would have
made 2.88M floppies not work.
Use implied seeks on enhanced controllers.
Use multisector transfers on all controllers. Increase
ISADMA bounce buffers accordingly.
Fall back to single sector when retrying. Reset retry count
on every successful transaction.
Sort functions in a more sensible order and generally tidy
up a fair bit here and there.
Assorted related fixes and adjustments in userland utilities.
WORKAROUNDS:
Do allow r/w opens of r/o media but refuse actual write
operations. This is necessary until the p4::phk_bufwork
branch gets integrated (This problem relates to remounting
not reopening devices, see sys/*/*/${fs}_vfsops.c for details).
Keep PC98's private copy of the old floppy driver compiling
and presumably working (see below).
TODO (planned)
Move probing of drives until after interrupts/timeouts work
(like for ATA/SCSI drives).
TODO (unplanned)
This driver should be made to work on PC98 as well.
Test on YE-DATA PCMCIA floppy drive.
Fix 2.88M media.
This is a MT5 candidate (depends on the bioq_takefirst() addition).
This gets us the info we need on systems which have proprietary tables that
don't match the standard. For instance, an AMI system has a table of type
"OEMB" with an invalid checksum.

ACPI and then disable it on many systems and trying to do so can cause
crashes, interrupt storms, etc. Binary compatibility with userland is

now include the contents if any SSDT table as well. This makes use
of the property that one can concatenate the body of SSDT tables to
the DSDT, updating the DSDT header (length and checksum) and end up
with a larger and valid DSDT table. Hence, this also works with -f.

another process already has /dev/snp0 open, the snp(4) will return
EBUSY, in which case watch will try to open /dev/snp1..9. Currently
watch does not check errno to see if the failure was a result of EBUSY.
This results in watch making futile attempts to open snp0..snp9 even
though devices may not exist or the caller does not have permissions
to access the device.
In addition to this, it attempts to setup the screen for snooping even
though it may not ever get an snp device.
So this patch does two things
1) Checks errno for EBUSY, if open(2) fails for another reason
print that reason and exit.
2) setup the terminal for snooping after the snp descriptor has
been obtained.

install of Postfix fails since Postfix 1 is picked from INDEX instead
of Postfix 2.
The problem is that the package_add function matches multiple Postfix
packages and then installs a "random" version (the last one found in
INDEX). This does not occur with a CD-ROM install since there is only
one Postfix package on the CD-ROM.
The correct solution to this would be to check the origin field from
INDEX instead of the package name, but due to the way sysinstall is
made that is not trivial, so instead work around the problem by
hard-coding the Postfix major and minor revision (for the current
stable version) to install directly into the package_add call.

or 'env MAKEOBJDIRPREFIX=... make' depending on the setting of
MAKEOBJDIRPREFIX in the environment. In any case this line kills the
original value of ${MAKE}. When during buildworld a new make is built (as
is the case during the upgrade) this causes a wrong make to be picked up
(the first one in the path). Use the same technique as Makefile.inc1:
create a MAKEENV variable and a CRUNCHMAKE that calls ${MAKE} with that
MAKEENV prefixed. Use CRUNCHMAKE instead of MAKE throughout the generated
makefile. This leaves the original ${MAKE} undisturbed.
