81229669a4 Add support for PWM controlled fans. I found these fans on my PowerMac9,1.
These fans are not located under the same node as the the RPM controlled ones,
So I had to adapt the current source to parse and fill the properties correctly.
To control the fans we can set the PWM ratio via sysctl between 20 and 100%.

77002eeb6c Fix tls base computation with COMPAT_FREEBSD32 on n64 kernels. The previous
version was missing an else and would always use the n64 TP_OFFSET.  Eliminate
some duplication of logic here.

It may be worth getting rid of some of the ifdefs and introducing gratuitous
SV_ILP32 runtime checks on n64 kernels without COMPAT_FREEBSD32 and on o32
kernels, similarly to how PowerPC works.

ae227ddf7f Revert r232473. I have been convinced by Doug Barton and Bjoern Zeeb
that it is better to error out when people attempt to build using the
wrong bsd.*.mk files, than to silently ignore the problem.

This means, that after this commit, if you want to build kernel modules
by hand (or via a port) from a head source tree, you *must* make sure
the files in /usr/share/mk are in sync with that tree.  If that isn't
possible, for example when you are running on an older FreeBSD branch,
you can:

- Run "make buildenv" from your head source tree, to have the correct
  environment setup.  (It's advisable to have run "make buildworld", or
  at a minimum "make toolchain" first.)
- Alternatively, set MAKESYSPATH to the share/mk directory under your
  head source tree.  If your build tools are too old, other problems may
  still occur.
- Alternatively, use "make -m" and specify the share/mk directory under
  your head source tree.  Again, build tools that are too old may still
  result in trouble.

35f5c46c91 After r232322, it turned out many people (and some ports) are building
kernel modules using their old installed /usr/share/mk/bsd.*.mk files,
instead of the updated ones in their source tree.  This leads to errors
like:

  "sys/conf/kmod.mk", line 111: Malformed conditional (${MK_CLANG_IS_CC} == "no" && ${CC:T:Mclang} != "clang")

Obviously, these errors will go away after a "make installworld", or
alternatively, by using "make buildenv" before attempting to manually
build modules.

However, since it is apparently an expected use case to build using old
.mk files, change the way we test for clang, so it also works when the
MK_CLANG_IS_CC macro doesn't exist.

Note the conditional expressions are becoming rather unreadable now, but
I will attempt to fix that on a followup commit.

432277f0fa The name caching changes of r230394 exposed an intermittent bug
in the new NFS server for NFSv4, where it would report ENOENT
when the file actually existed on the server. This turned out
to be caused by not initializing ni_topdir before calling lookup()
and there was a rare case where the value on the stack location
assigned to ni_topdir happened to be a pointer to a ".." entry,
such that "dp == ndp->ni_topdir" succeeded in lookup().
This patch initializes ni_topdir to fix the problem.

50c253779f o) Add COMPAT_FREEBSD32 support for MIPS kernels using the n64 ABI with userlands
using the o32 ABI.  This mostly follows nwhitehorn's lead in implementing
   COMPAT_FREEBSD32 on powerpc64.
o) Add a new type to the freebsd32 compat layer, time32_t, which is time_t in the
   32-bit ABI being used.  Since the MIPS port is relatively-new, even the 32-bit
   ABIs use a 64-bit time_t.
o) Because time{spec,val}32 has the same size and layout as time{spec,val} on MIPS
   with 32-bit compatibility, then, disable some code which assumes otherwise
   wrongly when built for MIPS.  A more general macro to check in this case would
   seem like a good idea eventually.  If someone adds support for using n32
   userland with n64 kernels on MIPS, then they will have to add a variety of
   flags related to each piece of the ABI that can vary.  That's probably the
   right time to generalize further.
o) Add MIPS to the list of architectures which use PAD64_REQUIRED in the
   freebsd32 compat code.  Probably this should be generalized at some point.

f633984c25 Post r230394, the Lookup RPC counts for both NFS clients increased
significantly. Upon investigation this was caused by name cache
misses for lookups of "..". For name cache entries for non-".."
directories, the cache entry serves double duty. It maps both the
named directory plus ".." for the parent of the directory. As such,
two ctime values (one for each of the directory and its parent) need
to be saved in the name cache entry.
This patch adds an entry for ctime of the parent directory to the
name cache. It also adds an additional uma zone for large entries
with this time value, in order to minimize memory wastage.
As well, it fixes a couple of cases where the mtime of the parent
directory was being saved instead of ctime for positive name cache
entries. With this patch, Lookup RPC counts return to values similar
to pre-r230394 kernels.

951ff6f5dc Fix a problem that was causing the mpt(4) driver to attach to MegaRAID
cards that should be handled by the mfi(4) driver.

The root of the problem is that the mpt(4) driver was masking off the
bottom bit of the PCI device ID when deciding which cards to attach to.

It appears that a number of the mpt(4) Fibre Channel cards had a LAN
variant whose PCI device ID was just one bit off from the FC card's device
ID.  The FC cards were even and the LAN cards were odd.

The problem was that this pattern wasn't carried over on the SAS and
parallel SCSI mpt(4) cards.  Luckily the SAS and parallel SCSI PCI device
IDs were either even numbers, or they would get masked to a supported
adjacent PCI device ID, and everything worked well.

Now LSI is using some of the odd-numbered PCI device IDs between the 3Gb
SAS device IDs for their new MegaRAID cards.  This is causing the mpt(4)
driver to attach to the RAID cards instead of the mfi(4) driver.

The solution is to stop masking off the bottom bit of the device ID, and
explicitly list the PCI device IDs of all supported cards.

This change should be a no-op for mpt(4) hardware.  The only intended
functional change is that for the 929X, the is_fc variable gets set.  It
wasn't being set previously, but needs to be because the 929X is a Fibre
Channel card.

d6e546f14a - Add a bus_dma tag to each PCI bus that is a child of a Host-PCI bridge.
The tag enforces a single restriction that all DMA transactions must not
  cross a 4GB boundary.  Note that while this restriction technically only
  applies to PCI-express, this change applies it to all PCI devices as it
  is simpler to implement that way and errs on the side of caution.
- Add a softc structure for PCI bus devices to hold the bus_dma tag and
  a new pci_attach_common() routine that performs actions common to the
  attach phase of all PCI bus drivers.  Right now this only consists of
  a bootverbose printf and the allocate of a bus_dma tag if necessary.
- Adjust all PCI bus drivers to allocate a PCI bus softc and to call
  pci_attach_common() from their attach routines.

8aaa665509 Attempt to catch scan cancellations at exactly the wrong time from occuring.
The scan code unlocks the comlock and calls into the driver.  It then
assumes the state hasn't changed from underneath it.

Although I haven't seen this particular condition trigger, I'd like to
be informed if I or anyone else sees it.

What I'm thinking may occur:

* A cancellation comes in during the scan_end call;
* the cancel flag is set;
* but it's never checked, so scandone isn't updated;
* .. and the interface stays in the STA power save mode.

It's a subtle race, if it even exists.

b23f922edf This change avoids a kernel deadlock on "snaplk" when using
snapshots on UFS filesystems running with journaled soft updates.
This is the first of several bugs that need to be fixed before
removing the restriction added in -r230250 to prevent the use
of snapshots on filesystems running with journaled soft updates.

The deadlock occurs when holding the snapshot lock (snaplk)
and then trying to flush an inode via ffs_update(). We become
blocked by another process trying to flush a different inode
contained in the same inode block that we need. It holds the
inode block for which we are waiting locked. When it tries to
write the inode block, it gets blocked waiting for the our
snaplk when it calls ffs_copyonwrite() to see if the inode
block needs to be copied in our snapshot.

The most obvious place that this deadlock arises is in the
ffs_copyonwrite() routine when it updates critical metadata
in a snapshot and tries to write it out before proceeding.
The fix here is to write the data and indirect block pointer
for the snapshot, but to skip the call to ffs_update() to
write the snapshot inode. To ensure that we will never have
to update a pointer in the inode itself, the ffs_snapshot()
routine that creates the snapshot has to ensure that all the
direct blocks are allocated as part of the creation of the
snapshot.

A less obvious place that this deadlock occurs is when we hold
the snaplk because we are deleting a snapshot. In the course of
doing the deletion, we need to allocate various soft update
dependency structures and allocate some journal space. If we
hit a resource limit while doing this we decrease the resources
in use by flushing out an existing dirty file to get it to give
up the soft dependency resources that it holds. The flush can
cause an ffs_update() to be done on the inode for the file that
we have selected to flush resulting in the same deadlock as
described above when the inode that we have chosen to flush
resides in the same inode block as the snapshot inode that we hold.
The fix is to defer cleaning up any time that the inode on which
we are operating is a snapshot.

This change fixes the long standing issue with nullfs(5) being in that
unix sockets did not work between lower and upper layers: if we bound
to a socket on the lower layer we could connect only to the lower
path; if we bound to the upper layer we could connect only to the
upper path. The new behavior is one can connect to both the lower and
