0eb8d2e84a Create a 'legacy' node for AMD64 as well as i386. While we'll never
have to use it since all AMD64 machines are supposed to have acpi etc,
I'm using it during development so I can avoid the acpi code for now.
Yes, this is cheating.

891619a66d Use bioq_flush() to drain a bio queue with a specific error code.
Retain the mistake of not updating the devstat API for now.

Spell bioq_disksort() consistently with the remaining bioq_*().

#include <geom/geom_disk.h> where this is more appropriate.

227f9a1c58 - Add vm_paddr_t, a physical address type. This is required for systems
where physical addresses larger than virtual addresses, such as i386s
  with PAE.
- Use this to represent physical addresses in the MI vm system and in the
  i386 pmap code.  This also changes the paddr parameter to d_mmap_t.
- Fix printf formats to handle physical addresses >4G in the i386 memory
  detection code, and due to kvtop returning vm_paddr_t instead of u_long.

Note that this is a name change only; vm_paddr_t is still the same as
vm_offset_t on all currently supported platforms.

7ac40f5f59 Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

07159f9c56 Cleanup of the d_mmap_t interface.
- Get rid of the useless atop() / pmap_phys_address() detour.  The
  device mmap handlers must now give back the physical address
  without atop()'ing it.
- Don't borrow the physical address of the mapping in the returned
  int.  Now we properly pass a vm_offset_t * and expect it to be
  filled by the mmap handler when the mapping was successful.  The
  mmap handler must now return 0 when successful, any other value
  is considered as an error.  Previously, returning -1 was the only
  way to fail.  This change thus accidentally fixes some devices
  which were bogusly returning errno constants which would have been
  considered as addresses by the device pager.
- Garbage collect the poorly named pmap_phys_address() now that it's
  no longer used.
- Convert all the d_mmap_t consumers to the new API.

I'm still not sure wheter we need a __FreeBSD_version bump for this,
since and we didn't guarantee API/ABI stability until 5.1-RELEASE.

91f1c2b3cc Split the global timezone structure into two integer fields to
prevent the compiler from optimizing assignments into byte-copy
operations which might make access to the individual fields non-atomic.

Use the individual fields throughout, and don't bother locking them with
Giant: it is no longer needed.

238dd3209a Split statclock into statclock and profclock, and made the method for driving
statclock based on profhz when profiling is enabled MD, since most platforms
don't use this anyway.  This removes the need for statclock_process, whose
only purpose was to subdivide profhz, and gets the profiling clock running
outside of sched_lock on platforms that implement suswintr.
Also changed the interface for starting and stopping the profiling clock to
do just that, instead of changing the rate of statclock, since they can now
be separate.

294d88444b Bail out of fd_clone() if the parsed unit number doesn't match our
expectation.

This solves the problem, where in a constellation with two (or more)
drives, an attempt is made to access a device name for that device
using a historic partition letter, like /dev/fd1c.  This is supposed
to create a symlink to the master device, but previously, the link was
always created to /dev/fd0, even if the request was for fd1*.

92a306a2b6 Use the correct value when writing the Day Of Week byte in the CMOS.
The correct range is [1...7] with Sunday=1, but we have been writing
[0...6] with Sunday=0.

The Soekris computers flagged the zero, zapped the date, so if you
rebooted your soekris on a sunday, it would come up with a wrong
date.

Bruce has a more extensive rework of this code, but we will stick with
the minimalist fix for now.

0ebefa8c4e 1. Fix a comment. Locking _is_ needed (but not done).
2. Update a comment.  We now restore much more than RTC updates and
   interrupts.
3. Order change.  Stop interrupts by writing to RTC_STATUSB,
   restore rate bits for the interrupts by writing to RTC_STATUSA,
   then enable interrupts again.
   This seems to be done perfectly backwards in startrtclock().
   Otherwise, the idea for this change was obtained from
   startrtclock().
4. Don't stop the clock (RTCB_HALT).  We only program some control bits
   and don't want to stop the clock.
5. (Not really related.)  Add caveats to the comment about timer_restore().
   The update is non-atomic since locking is not done.

On locking:
6. rtcin() and writertc() are locked() adequately by splhigh() in RELENG_4,
   but this locking is null in -current.
7. Doing things in the correct order in (3) combined with (6) is probably
   enough locking for rtcrestore() in RELENG_4.  In -current, the
   writertc()'s race with rtcintr() unless the BIOS disables RTC interrupts.

homerolling our own version.
- Rename the enum for memsize from ISA_IVAR_MSIZE to ISA_IVAR_MEMSIZE
  since using 'MSIZE' in the macro invocation of ISA_ACCESSOR() conflicts
  with the 'MSIZE' kernel option.  The accessor function is still
  isa_get_msize().

f90c382c0c Make FreeBSD "struct disklabel" agnostic, step 311 of 723:
Rename diskerr() to disk_err() for naming consistency.

Drop the by now entirely useless struct disklabel argument.

Add a flag argument for new-line termination.

Fix a couple of printf-format-casts to %j instead of %l.

Correctly print the name of all bio commands.

Move the function from subr_disklabel.c to subr_disk.c,
and from <sys/disklabel.h> to <sys/disk.h>.

Use the new disk_err() throughout, #include <sys/disk.h> as needed.

Bump __FreeBSD_version for the sake of the aac disk drivers #ifdefs.

Remove unused disklabel members of softc for aac, amr and mlx, which seem
to originally have been intended for diskerr() use, but which only rotted
and got Copy&Pasted at least two times to many.
