562894f0dc Centralize compatability translation macros.
Copy the CP, PTRIN, etc macros from freebsd32.h into a sys/abi_compat.h
and replace existing definitation with includes where required. This
eliminates duplicate code and allows Linux and FreeBSD compatability
headers to be included in the same files.

6469bdcdb6 Move most of the contents of opt_compat.h to opt_global.h.
opt_compat.h is mentioned in nearly 180 files. In-progress network
driver compabibility improvements may add over 100 more so this is
closer to "just about everywhere" than "only some files" per the
guidance in sys/conf/options.

Keep COMPAT_LINUX32 in opt_compat.h as it is confined to a subset of
sys/compat/linux/*.c.  A fake _COMPAT_LINUX option ensure opt_compat.h
is created on all architectures.

Move COMPAT_LINUXKPI to opt_dontuse.h as it is only used to control the
set of compiled files.

5f5baf0e96 Update mpr(4) driver from v15 to v18 from Broadcom site.
Version 16 is just a number bump, since we already had those changes.

Version 17 introduces new AdapterType value, that allows new user-space
tools from Broadcom to differentiate adapter generations 3 and 3.5.

Version 18 updates headers and adds SAS_DEVICE_DISCOVERY_ERROR reporting.

e2997a03b7 Diagnostic buffer fixes for the mps(4) and mpr(4) drivers.
In mp{r,s}_diag_register(), which is used to register diagnostic
buffers with the mp{r,s}(4) firmware, we allocate DMAable memory.

There were several issues here:
 o No checking of the bus_dmamap_load() return value.  If the load
   failed or got deferred, mp{r,s}_diag_register() continued on as if
   nothing had happened.  We now check the return value and bail
   out if it fails.

 o No waiting for a deferred load callback.  bus_dmamap_load()
   calls a supplied callback when the mapping is done.  This is
   generally done immediately, but it can be deferred.
   mp{r,s}_diag_register() did not check to see whether the callback
   was already done before proceeding on.  We now sleep until the
   callback is done if it is deferred.

 o No call to bus_dmamap_sync(... BUS_DMASYNC_PREREAD) after the
   memory is allocated and loaded.  This is necessary on some
   platforms to synchronize host memory that is going to be updated
   by a device.

Both drivers would also panic if the firmware was reinitialized while
a diagnostic buffer operation was in progress.  This fixes that problem
as well.  (The driver will reinitialize the firmware in various
circumstances, but the problem I ran into was that the firmware would
generate an IOC Fault due to a PCIe error.)

mp{r,s}var.h:
	Add a new structure, struct mpr_busdma_context, that is
	used for deferred busdma load callbacks.

	Add a prototype for mp{r,s}_memaddr_wait_cb().
mp{r,s}.c:
	Add a new busdma callback function, mp{r,s}_memaddr_wait_cb().
	This provides synchronization for callers that want to
	wait on a deferred bus_dmamap_load() callback.

mp{r,s}_user.c:
	In bus_dmamap_register(), add a call to bus_dmamap_sync()
	with the BUS_DMASYNC_PREREAD flag set after an allocation
	is loaded.

	Also, check the return value of bus_dmamap_load().  If it
	fails, bail out.  If it is EINPROGRESS, wait for the
	callback to happen.  We use an interruptible sleep (msleep
	with PCATCH) and let the callback clean things up if we get
	interrupted.

	In mpr_diag_read_buffer() and mps_diag_read_buffer(), call
	bus_dmamap_sync(..., BUS_DMASYNC_POSTREAD) before copying
	the data out to make sure the data is in stable storage.

	In mp{r,s}_post_fw_diag_buffer() and
	mp{r,s}_release_fw_diag_buffer(), check the reply to see
	whether it is NULL.  It can be NULL (and the command non-NULL)
	if the controller gets reinitialized while we're waiting for
	the command to complete but the driver structures aren't
	reallocated.  The driver structures generally won't be
	reallocated unless there is a firmware upgrade that changes
	one of the IOCFacts.

	When freeing diagnostic buffers in mp{r,s}_diag_register()
	and mp{r,s}_diag_unregister(), zero/NULL out the buffer after
	freeing it.  This will prevent a duplicate free in some
	situations.

6d4ffcb4ac Changes to make mps(4) and mpr(4) handle reinit with reallocation.
When the mps(4) and mpr(4) drivers need to reinitialize the
firmware, they sometimes need to reallocate all of the memory
allocated by the driver.  The reallocation happens whenever the IOC
Facts change.  That should only happen after a firmware upgrade.

If the reinitialization happens as a result of a timed out command
sent to the card, the command that timed out and triggered the
reinit may have been freed if iocfacts_allocate() reallocated all
memory.  If the caller attempts to access the command after that,
the kernel will panic because the caller will be dereferencing
freed memory.

The solution is to set a flag in the softc when we reallocate,
and avoid dereferencing the command strucure if we've reallocated.

The changes are largely the same in both drivers, since mpr(4) is a
derivative of mps(4).

 o In iocfacts_allocate(), if the IOC Facts have changed and we
   need to reallocate, set the REALLOCATED flag in the softc.

 o Change wait_command() to take a struct mps_command ** instead of
   a struct mps_command *.  This allows us to NULL out the caller's
   command pointer if we have to reinit the controller and the data
   structures get reallocated.  (The REALLOCATED flag will be set
   in the softc if that has happened.)

 o In every place that calls wait_command(), make sure we handle
   the case where the command is NULL after the call.

 o The mpr(4) driver has mpr_request_polled() which can also
   reinitialize the card.  Also check for reallocation there.

a2c1487946 The wrong commit message was given with r283632. This is the correct message.
- Updated all files with 2015 Avago copyright, and updated LSI's copyright
  dates.

- Changed all of the PCI device strings from LSI to Avago Technologies (LSI).

- Added a sysctl variable to control how StartStopUnit behavior works. User can
  select to spin down disks based on if disk is SSD or HDD.

- Inquiry data is required to tell if a disk will support SSU at shutdown or
  not. Due to the addition of mpssas_async, which gets Advanced Info but not
  Inquiry data, the setting of supports_SSU was moved to the
  mpssas_scsiio_complete function, which snoops for any Inquiry commands. And,
  since disks are shutdown as a target and not a LUN, this process was
  simplified by basing it on targets and not LUNs.

- Added a sysctl variable that sets the amount of time to retry after sending a
  failed SATA ID command. This helps with some bad disks and large disks that
  require a lot of time to spin up. Part of this change was to add a callout to
  handle timeouts with the SATA ID command. The callout function is called
  mpssas_ata_id_timeout(). (Fixes PR 191348)

- Changed the way resets work by allowing I/O to continue to devices that are
  not currently under a reset condition. This uses devq's instead of simq's and
  makes use of the MPSSAS_TARGET_INRESET flag. This change also adds a function
  called mpssas_prepare_tm().

- Some changes were made to reduce code duplication when getting a SAS address
  for a SATA disk.

- Fixed some formatting and whitespace.

- Bump version of mps driver to 9.255.01.00-fbsd

991554f2c4 Bring in the mpr(4) driver for LSI's MPT3 12Gb SAS controllers.
This is derived from the mps(4) driver, but it supports only the 12Gb
IT and IR hardware including the SAS 3004, SAS 3008 and SAS 3108.

Some notes about this driver:
 o The 12Gb hardware can do "FastPath" I/O, and that capability is included in
   this driver.

 o WarpDrive functionality has been removed, since it isn't supported in
   the 12Gb driver interface.

 o The Scatter/Gather list handling code is significantly different between
   the 6Gb and 12Gb hardware.  The 12Gb boards support IEEE Scatter/Gather
   lists.

Thanks to LSI for developing and testing this driver for FreeBSD.
