f446f9def7 Make isa_dma functions MPSAFE by introducing its own private lock. These
functions are selfcontained (ie. they touch only isa_dma.c static variables
and hardware) so a private lock is sufficient to prevent races. This changes
only i386/amd64 while there are also isa_dma functions for ia64/sparc64.
Sparc64 are ones empty stubs and ia64 ones are unused as ia64 does not
have isa (says marcel).

This patch removes explicit locking of Giant from a few drivers (there
are some that requires this but lack ones - this patch fixes this) and
also removes the need for implicit locking of Giant from attach routines
where it's provided by newbus.

8c4a62bd5b With the fdc control device disappearing some 5 years ago, it is no
longer useful for the FD_STYPE and FD_SOPTS ioctls to insist on being
issued on a writable file descriptor.  Otherwise, there's no longer a
chance to set the drive type or options when a read-only medium is
present in the drive, as there is no way to obtain a writable fd then.

5807aa9312 - Revive fdc(4) per-device flag 0x10, which was removed in r1.284[1].
- If the flag is set and auto-select fails, assume disk is not present.
- Set disk empty flag only when the floppy controller reset is needed.
It fixes regression introduced in r1.311, which prevented it from ignoring
errors.  Now fdformat(1) and dd(1) with conv=noerror option can continue
when read/write errors occur as they should.
- Do not retry disk probing as it is extremely slow and pointless.
- Move the disk probing code into a separate function.
- Do not reset disk empty flag if write-protect check fails somehow.

508466854a The wakeup() line from the rev. 1.319 is wrong and reintroduces
a panic race on module unload. The wakeup() is internal to
kproc_exit/kthread_exit. The correct fix is to fix the msleep() in

51d643caa6 Rename the kthread_xxx (e.g. kthread_create()) calls
to kproc_xxx as they actually make whole processes.
Thos makes way for us to add REAL kthread_create() and friends
that actually make theads. it turns out that most of these
calls actually end up being moved back to the thread version
when it's added. but we need to make this cosmetic change first.

I'd LOVE to do this rename in 7.0  so that we can eventually MFC the
new kthread_xxx() calls.

21e00b8d70 Assume floppy disk is not inserted when we have exhausted retries. This
significantly reduces booting time when there is broken floppy disk drive,
controller, cable, BIOS, etc.
When the floppy controller interface is correctly implemented, disk change
signal (DSKCHG) is reflected in the Digital Input Register (DIR) at 0x3f7.
However, there are many cases that the signal is unusable.  Moreover, some
BIOS does not reserve the port at all.  In those cases, the register may not
function.

c025122efb Enhanced floppy controllers have Data Rate Select Register (DSR) at 0x3f4.
Use it to reset controller and to select data rate.  According to Intel
80277AA datasheet, software reset behaves the same as DOR reset except
that it is self clearing.  National Semiconductor PC8477B datasheet says
the same.  As a side effect, we no longer use Configuration Control
Register (CCR) at 0x3f7 for these controllers, which is often missing
in modern hardware.

110e3dcc24 - Use callout_init_mtx() to initialize toffhandle callout using the fdc's
mutex.
- Don't use callout_drain() to stop the toffhandle callout while holding the
  fdc mutex (this could deadlock) in functions called from softclock
  (callouts aren't allowed to do voluntary sleeps).  Instead, use
  callout_stop().  Note that since we hold the associated mutex and are now
  using callout_init_mtx(), callout_stop() is just as effective as
  callout_drain().  (Though callout_drain() is still needed in detach to
  make sure softclock isn't contesting on our mutex before we destroy the
  mutex.)
- Remove unused callout 'tohandle' from softc.

a7b3bd4564 If we fail a sanity check for the resources just allocated, make sure
that we free that resource.  All the other resources are freed in
their own routine, but since we haven't saved a pointer to this one,
it is leaked.  This is the failure case that lead to the sio ports
that weren't working, I think.

d0ffad32b5 Fix a couple of problems with the probe code when used with pnpbios
resources.  When allocating 6 ports for a 4 port range isa code
returns an error.  I'm not sure yet why this is the case, but suspect
it is just a non-regularity in how the resource allocation code works
which should be corrected.  Use 1 as the ports size in this case.
However, in the hints case, we have to specify the length, so use 6 in
that case.  I believe that this is also acpi friendly.

Also, complain when we can't allocate FDOUT register space.  Right now we
silently fail when we can't.  This failure is referred to above.

When there's no resource for FDCTL, go ahead and allocate one by hand.
Many PNPBIOS tables don't list this resource, and our hints mechanism also
doesn't cover that range.  If we can't allocate it, whine, but fake up
something.  Before, we were always bogusly faking it and no one noticed
the sham (save the original author who has now fixed his private shame).

65cbf19ef7 MFp4: overhaul of resource allocation
Rather than have a twisty maze of special case allocations, move
instead to a data driven allocation.  This should be the most robust
way to cope with the resource problems that the multiplicity of ways
of encoding 5 registers that have the misfortune of not being a power
of 2 nor contiguous.

Also, make it less impossible that pccard will work.  I've not been able
to get my libretto floppy working, but it now fails later than before.

phk and I had similar ideas on this during the 5.3 release cycle, but
it wasn't until recently that I could test more than one allocation
scenario.

ea0652cf81 Yet another case of resources:
+        * 9:   0x3f0-0x3f3,0x3f4-0x3f5,0x3f7

This requires only one change to support.  Rather than keying on the
size of the resource being 2, instead key off the end & 7 being 3.
This covers the same cases that the size of 2 would catch, but also
covers the new above case.

In addition, I think it is clearer to use the end in preference to the
size and start for case #8 as well.  Turns two tests into one, and
catches no other cases.

Make minor commentary changes to deal with new case #9.

# This change is specifically minimal to allow easy MFC.  A more
# extensive change will go into current once I've had a chance to test
# it on a lot of hardware...
