217578215b Avoid GCC optimizations from injecting a call to memset(?) in order
to initialize the buffer array in ata_raid_attach() by removing the
initializer. There's no memset(?) in the kernel. Instead, assign
'\0' to the first element. The buffer array holds strings only, so
this is functionally equivalent.

9aa0eba464 - Add KTR_VFS tracing to track the life of vnodes. Eventually KTR_VFS
events could be added to cover other interesting details.
 - Add some VNASSERTs to discover places where we access vnodes after
   they have been uma_zfree'd before we try to free them again.
 - Add a few more VNASSERTs to vdestroy() to be certain that the vnode is
   really unused.

5201165c85 - Replace the unused KTR_NFS with KTR_VFS. KTR_VFS differs from KTR_VOP
in that KTR_VFS will be hand placed, while KTR_VOP traces the individual
   vnode operations and is generated by vnode_if.awk.
 - Add a comment describing KTR_VOP.

f32e678d0c Add an evil hack to work around a cast from the softc to the ifnet that
I missed.  Since I did no rearrange any softcs, casting the result of
device_get_softc() to (struct ifnet **) and derefrencing it yeilds a
pointer to the ifp.  This makes at least vr(4) nics work.

a534973af4 The new contigmalloc(9) has a bad degenerate case where there were
many regions checked again and again despite knowing the pages
contained were not usable and only satisfied the alignment constraints
This case was compounded, especially for large allocations, by the
practice of looping from the top of memory so as to keep out of the
important low-memory regions.  While the old contigmalloc(9) has the
same problem, it is not as noticeable due to looping from the low
memory to high.

This degenerate case is fixed, as well as reversing the sense of the
rest of the loops within it, to provide a tremendous speed increase.
This makes the best case O(n * VM overhead) much more likely than the
worst case O(4 * VM overhead).  For comparison, the worst case for old
contigmalloc would be O(5 * VM overhead) in addition to its strategy
of turning used memory into free being highly pessimal.

Also, fix a bug that in practice most likely couldn't have been triggered,
int the new contigmalloc(9): it walked backwards from the end of memory
without accounting for how many pages it needed.  Potentially, nonexistant
pages could have been mapped.  This hasn't occurred because the kernel
generally requests as its first contigmalloc(9) a single page.

cc3149b1ea Fix a serious deadlock with the NFS client. Given a large enough
atomic write request, it can fill the buffer cache with the entirety
of that write in order to handle retries.  However, it never drops
the vnode lock, or else it wouldn't be atomic, so it ends up waiting
indefinitely for more buf memory that cannot be gotten as it has it
all, and it waits in an uncancellable state.

To fix this, hibufspace is exported and scaled to a reasonable
fraction.  This is used as the limit of how much of an atomic write
request by the NFS client will be handled asynchronously.  If the
request is larger than this, it will be turned into a synchronous
request which won't deadlock the system.  It's possible this value is
far off from what is required by some, so it shall be tunable as soon
as mount_nfs(8) learns of the new field.

The slowdown between an asynchronous and a synchronous write on NFS
appears to be on the order of 2x-4x.

a3d97e12a0 Turn on atkbdc(4), atkbd(4), creator(4), machfb(4), syscons(4), ohci(4),
psm(4), ukbd(4), ums(4) and usb(4) on by default. Modulo some nits with
the most annoying one probably being USB keyboards no longer working at
the OFW boot prompt after halting FreeBSD these drivers work fine on
sparc64 including X and there's nothing left that I'd consider a show-
stopper. I.e. graphical consoles on sun4u machines should either work
out of the box or by plugging in a card that is supported by either
creator(4) or machfb(4). The exception obviously are SBus-only machines
without UPA slots like some Ultra 1 (but which also still lack support
in other areas) and certain Exx0 (but which probably are mainly used
with serial consoles anyway). I'll try to add a cgsix(4) for these later
as Sun CG6 cards are probably the most common SBus framebuffer cards in
sun4u machines. I however don't see much sense in adding drivers for the
dozen of SBus framebuffers that were destined for sparc v8 machines.
The rest of the USB drivers aren't enabled as I'm only aware of ukbd(4)
and ums(4) as well as ohci(4) working with the on-board ALI M5237 and
Sun PCIO-2 controllers. Aue(4) definitely doesn't work on sparc64, yet.

Thanks to:
- Jake for the initial work on syscons(4) on sparc64 and creator(4).
- Marcel for uart(4) and especially for its support for the SCCs which
  are only used on sparc64 so far. In various regards it wouldn't have
  been possible to enable syscons(4) by default on sparc64, yet, without
  uart(4).
- All that tested patches.

9a472268c8 - In preparation to turning syscons(4) etc. on by default in the sparc64
GENERIC comment in ttyN.
- Add the name of the device driver creating the device nodes above the
  respectives blocks so it's easier for user to find the right entry to
  shut up warnings from getty(8). Replace 'Requires device 'uart' be
  enabled.' with just 'uart(4)' as the former referred to a sparc64
  GENERIC back when uart(4) wasn't enabled by default, yet.
- Turn off the getty(8) on screen as screen is created by ofw_console(4)
  which is no longer enabled in the sparc64 GENERIC (and also only is a
  last resort) to shut up warnings from getty(8) with the current GENERIC.

520b635320 - Hook up the new locations of the atkbdc(4), atkbd(4) and psm(4) source
files after they were repo-copied to sys/dev/atkbdc. The sources of
  atkbdc(4) and its children were moved to the new location in preparation
  for adding an EBus front-end to atkbdc(4) for use on sparc64; i.e. in
  order to not further scatter them over the whole tree which would have
  been the result of adding atkbdc_ebus.c in e.g. sys/sparc64/ebus. Another
  reason for the repo-copies was that some of the sources were misfiled,
  e.g. sys/isa/atkbd_isa.c wasn't ISA-specific at all but for hanging
  atkbd(4) off of atkbdc(4) and was renamed to atkbd_atkbdc.c accordingly.
  Most of sys/isa/psm.c, i.e. expect for its PSMC PNP part, also isn't
  ISA-specific.
- Separate the parts of atkbdc_isa.c which aren't actually ISA-specific
  but are shareable between different atkbdc(4) bus front-ends into
  atkbdc_subr.c (repo-copied from atkbdc_isa.c). While here use
  bus_generic_rl_alloc_resource() and bus_generic_rl_release_resource()
  respectively in atkbdc_isa.c instead of rolling own versions.
- Add sparc64 MD bits to atkbdc(4) and atkbd(4) and an EBus front-end for
  atkbdc(4). PS/2 controllers and input devices are used on a couple of
  Sun OEM boards and occur on either the EBus or the ISA bus. Depending on
  the board it's either the only on-board mean to connect a keyboard and
  mouse or an alternative to either RS232 or USB devices.
- Wrap the PSMC PNP part of psm.c in #ifdef DEV_ISA so it can be compiled
  without isa(4) (e.g. for EBus-only machines). This ISA-specific part
  isn't separated into its own source file, yet, as it requires more work
  than was feasible for 6.0 in order to do it in a clean way. Actually
  philip@ is working on a rewrite of psm(4) so a more comprehensive
  clean-up and separation of hardware dependent and independent parts is
  expected to happen after 6.0.

fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

b34d56f1ef Modify send_pkt() to return the generated packet and have the caller
do the subsequent ip_output() in IPFW.  In ipfw_tick(), the keep-alive
packets must be generated from the data that resides under the
stateful lock, but they must not be sent at that time, as this would
cause a lock order reversal with the normal ordering (interface's
lock, then locks belonging to the pfil hooks).

In practice, this caused deadlocks when using IPFW and if_bridge(4)
together to do stateful transparent filtering.
