2eea70515c Overhaul error handling in the IPS driver. Don't use a magic value for
driver-induced errors, instead be better about propagating error status
upwards.  Add more error definitions, courtesy of the linux driver.  Fix
a command leak in the ioctl handler.  Re-arrange some of the command handlers
to localize error handling.

03a908f2ce Lock the IPS driver and bring it out from under Giant. Also do some
significant clean up and optimizations:
- don't call bioq_disksort() on every command, the hardware will do that for
  us.
- remove all of the complicated bio deferral code.  bio's that can't be
  serviced immediately can just wait on the bioq.
- Only reserve one command object for doing control commands to the card.
  This simplifies a lot of code and significantly reduces the size of the
  command struct.
- Allocate commands out of a slab instead of embedding them into the softc.
- Call the command action method directly instead of having ips_get_free_cmd()
  call it indirectly.

4717d22a7c Change the return value of sema_timedwait() so it returns 0 on
success and a proper errno value on failure.  This makes it
consistent with cv_timedwait(), and paves the way for the
introduction of functions such as sema_timedwait_sig() which can
fail in multiple ways.

Bump __FreeBSD_version and add a note to UPDATING.

0b7ed341e1 Change the disk(9) API in order to make device removal more robust.
Previously the "struct disk" were owned by the device driver and this
gave us problems when the device disappared and the users of that device
were not immediately disappearing.

Now the struct disk is allocate with a new call, disk_alloc() and owned
by geom_disk and just abandonned by the device driver when disk_create()
is called.

Unfortunately, this results in a ton of "s/\./->/" changes to device
drivers.

Since I'm doing the sweep anyway, a couple of other API improvements
have been carried out at the same time:

The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to
DISKFLAG_NEEDSGIANT

A version number have been added to disk_create() so that we can detect,
report and ignore binary drivers with old ABI in the future.

Manual page update to follow shortly.

7633e7f1a2 ServeRaid (at least 5i) didn't initialize correctly. To get
them working (cache, automatic rebuild and hotswap) the FFDC
info (First Failure Data Capture) on the adapter must be
initialised.

Logical drives in critical/degraded states weren't added to
the drive list. FreeBSD was not able to see a degraded array
after a reboot. Degraded drives are now also added to the drivelist
and the state of the logical drive is given at boottime.

The adapter type is detected from informations in nvram page 5
and displayed at boottime.

Change IPS_OS_FREEBSD definition from 10 to 8 according to IBM
specs.

8a9bc9c03b - Use the new resource_disabled() helper function to see if devices are
disabled.
- Change the apm driver to match the acpi driver's behavior by checking to
  see if the device is disabled in the identify routine instead of in the
  probe routine.  This way if the device is disabled it is never created.

Note that a few places (ips(4), Alpha SMP) used "disable" instead of
"disabled" for their hint names, and these hints must be changed to
"disabled".  If this is a big problem, resource_disabled() can always be
changed to honor both names.

f6b1c44d1f Mega busdma API commit.
Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
Lockfunc allows a driver to provide a function for managing its locking
semantics while using busdma.  At the moment, this is used for the
asynchronous busdma_swi and callback mechanism.  Two lockfunc implementations
are provided: busdma_lock_mutex() performs standard mutex operations on the
mutex that is specified from lockfuncarg.  dftl_lock() is a panic
implementation and is defaulted to when NULL, NULL are passed to
bus_dma_tag_create().  The only time that NULL, NULL should ever be used is
when the driver ensures that bus_dmamap_load() will not be deferred.
Drivers that do not provide their own locking can pass
busdma_lock_mutex,&Giant args in order to preserve the former behaviour.

sparc64 and powerpc do not provide real busdma_swi functions, so this is
largely a noop on those platforms.  The busdma_swi on is64 is not properly
locked yet, so warnings will be emitted on this platform when busdma
callback deferrals happen.

If anyone gets panics or warnings from dflt_lock() being called, please
let me know right away.

f472527c95 Fix pointer/int warnings so this compiles on amd64. The driver wants
to store an int in the bio->bio_driver1 (a void *).  It is big enough,

dea4622d59 - Zero the buffers used to hold configuration data from the card. Not doing
so can leave stale data in the buffer and confuse the driver.
- enable the ability to set the 'disable' hint for the driver to keep it
  from attaching.  i.e. 'hw.ips.0.disable=1' will prevent the driver from
  attaching.
- Only detach if attach suceeded.
