aa6e8dfdd5 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.

4228a524fd When creating a handle for a subregion, be sure to actually math out the new
handle address, where we're using handles as raw addresses.

This fixes devices with subregions on Octeon PCI specifically, and likely also on
MIPS more generally, where there isn't another bus_space in use that was doing the
math already.

1b1596a3b3 - 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.

e5fb99b712 Removed excessive _seekdir() call in closedir(). This saves one lseek()
syscall.  Before r5958, seekdir() was called for its side effect of
freeing memory allocated by opendir() for rewinddir(), but that revision
added _reclaim_telldir() that frees all memory allocated by telldir()
calls, making this call redundant.

This introduces a slight change.  If an application duplicated the descriptor
obtained through dirfd(), it can no longer rely on file position to be
reset to the start of file after a call to closedir().  It's believed to
be safe because neither POSIX, nor any other OS I've tested (NetBSD, Linux,
OS X) rewind the file offset pointer on closedir().

They were made excessive in r205424 by opening with O_DIRECTORY.
Also eliminated the fcntl() call used to set FD_CLOEXEC by opening

(fdopendir() still checks that the passed descriptor is a directory,
and sets FD_CLOEXEC on it.)

66b74386c7 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.

831ce4cb3d - Change contigmalloc() to use the vm_paddr_t type instead of an unsigned
long for specifying a boundary constraint.
- Change bus_dma tags to use bus_addr_t instead of bus_size_t for boundary
  constraints.

These allow boundary constraints to be fully expressed for cases where
sizeof(bus_addr_t) != sizeof(bus_size_t).  Specifically, it allows a
driver to properly specify a 4GB boundary in a PAE kernel.

Note that this cannot be safely MFC'd without a lot of compat shims due
to KBI changes, so I do not intend to merge it.

35338e6091 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.
