b75a3f5d87 - Use the PCI ID macros from mpi_cnfg.h rather than duplicating them here.
Note that this driver additionally probes some device IDs for the most
  part not know to other MPT drivers, if at all. So rename the macros not
  present in mpi_cnfg.h to match the naming scheme in the latter and but
  suffix them with a _FB in order to not cause conflicts.
- Like mpt_set_config_regs(), comment out mpt_read_config_regs() as the
  content of the registers read isn't actually used and both functions
  aren't exactly up to date regarding the possible layouts of the BARs
  (these function might be helpful for debugging though, so don't remove
  them completely).
- Use DEVMETHOD_END.
- Use NULL rather than 0 for pointers.
- Remove an unusual check for the softc being NULL.
- Remove redundant zeroing of the softc.
- Remove an overly banal and actually partly incorrect as well as partly
  outdated comment regarding the allocation of the memory resource.

fe30cce04e Use suspend/resume methods provided by net80211. This ensures that the
appropriate state handling takes place, not doing so results in the
device doing nothing until manual intervention.

a7368abeec Work around the following clang warning in mps(4):
sys/dev/mps/mps_sas.c:861:1: error: function 'mpssas_discovery_timeout' is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration]
  mpssas_discovery_timeout(void *data)
  ^

Because the driver is obtained from upstream, we don't want to modify
it; just silence the warning instead, it is harmless.

7232ff0e78 Check that scheme is not already registered. This may happens when a
KLD is preloaded with loader(8) and leads to infinity loops.

Also do not return EEXIST error code from MOD_LOAD handler, because
we have undocumented(?) ability replace kernel's module with preloaded one.
And if we have so, then preloaded module will be initialized first.
Thus error in MOD_LOAD handler will be triggered for the kernel.

e02fd6b842 Handle spurious page faults that may occur in no-fault sections of the
kernel.

When access restrictions are added to a page table entry, we flush the
corresponding virtual address mapping from the TLB.  In contrast, when
access restrictions are removed from a page table entry, we do not
flush the virtual address mapping from the TLB.  This is exactly as
recommended in AMD's documentation.  In effect, when access
restrictions are removed from a page table entry, AMD's MMUs will
transparently refresh a stale TLB entry.  In short, this saves us from
having to perform potentially costly TLB flushes.  In contrast,
Intel's MMUs are allowed to generate a spurious page fault based upon
the stale TLB entry.  Usually, such spurious page faults are handled
by vm_fault() without incident.  However, when we are executing
no-fault sections of the kernel, we are not allowed to execute
vm_fault().  This change introduces special-case handling for spurious
page faults that occur in no-fault sections of the kernel.

7bb0bdde2a Remove remnants of ATA_LOCKING uses in the ATA_CAM case and wrap it
along with functions, SYSCTLs and tunables that are not used with
ATA_CAM in #ifndef ATA_CAM, similar to the existing #ifdef'ed ATA_CAM
code for the other way around. This makes it easier to understand
which parts of ata(4) actually are used in the new world order and
to later on remove the !ATA_CAM bits. It also makes it obvious that
there is something fishy with the C-bus front-end as well as in the
ATP850 support, as these used ATA_LOCKING which is defunct in the
ATA_CAM case. When fixing the former, ATA_LOCKING probably needs to
be brought back in some form or other.

619ab2327e Remove pty(4) from our kernel configurations.
As of FreeBSD 8, this driver should not be used. Applications that use
posix_openpt(2) and openpty(3) use the pts(4) that is built into the
kernel unconditionally. If it turns out high profile depend on the
pty(4) module anyway, I'd rather get those fixed. So please report any
issues to me.

The pty(4) module is still available as a kernel module of course, so a
simple `kldload pty' can be used to run old-style pseudo-terminals.

3c3b82e681 Eliminate vm.pmap.shpgperproc and vm.pmap.pv_entry_max because they no
longer serve any purpose.  Prior to r157446, they served a purpose
because there was a fixed amount of kernel virtual address space
reserved for pv entries at boot time.  However, since that change pv
entries are accessed through the direct map, and so there is no limit
imposed by a fixed amount of kernel virtual address space.

Fix a couple of nearby style issues.
