2b83592fdc Remove Giant from CAM. Drivers (SIMs) now register a mutex that CAM will
use to synchornize and protect all data objects that are used for that
SIM.  Drivers that are not yet MPSAFE register Giant and operate as
usual.  RIght now, no drivers are MPSAFE, though a few will be changed
in the coming week as this work settles down.

The driver API has changed, so all CAM drivers will need to be recompiled.
The userland API has not changed, so tools like camcontrol do not need to
be recompiled.

c2175ff5ca Change the remainder of the drivers for DMA'ing devices enabled in the
sparc64 GENERIC and the sound device drivers known working on sparc64
to use bus_get_dma_tag() to obtain the parent DMA tag so we can get rid
of the sparc64_root_dma_tag kludge eventually. Except for ath(4), sk(4),
stge(4) and ti(4) these changes are runtime tested (unless I booted up
the wrong kernels again...).

b67e92b038 Attempt to fix Symbios driver on amd64. The private memory allocation
function provided by the driver limits allocations to the page size,
i.e. 4KB on i385 and 8KB on typical 64 bit processors. Since amd64
has 64 bit pointers, but only 4KB pages, an array of pointers that
just fits into one page on all the other processors, does require
2 pages on amd64.

In order to make this driver useful on amd64, the allocation unit
has been increased to 2 pages on amd64 and contigmalloc() is used
instead of malloc(). All other processor types are unaffected by
this change. This modification has only been compile-tested on
amd64, yet, but should just work (FLW).

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.

b1bec479be Fix:
- Missing cpu_to_scr() added (endian-ness).

Improvement (fix|workaroung??):
- Blindly firing a PPR can lead to some messy situations due to
  various causes or misfeatures, for example:
  * The 53C1010-[33|66] supports offset 62 in DT mode, but only
    offset 31 in ST mode. As a result, a PPR(DT, offset 62)
    responded with PPR(ST, any offset > 31) must be rejected.
  * A device that doesn't know about PPR should reject it, but
    may also be confused by this message.
  When a PPR encounters problems, the driver now patches the goal
  transfer settings for legacy negotiations to be performed later
  with the offending target. This give a chance for bad situations
  to be fixed automagically.

3c9013e257 A couple of chip errata work-arounds refined:
- When used on a 33MHz PCI BUS, the 53C1010-66 revision 0
  requires extra clocks to be inserted in data out phase.
  Revision 1 is fixed.
- The 53C1010-33 revision 1 requires internal cycles to be
  disabled due to possible contentions on IO registers.
  Revision 2 is fixed.
Fix:
- The probing of HVD from GPIO3 bit by the driver was reversed.
  The driver could misprobe the bus mode of a 825 or 875 chip
  that was not previously initialized (no BIOS for example).

- Properly deal with chips that have a 32 bit PCI

PR misc/17584 (at least partially addressed):
- Try detecting hardware combinations that trigger
  spurious PCI master parity error detections by the
  PCI chip. This work-around is implemented in the
  `snooptest' routine and consists in retrying with
  PCI master parity checking disabled if such an
  error is reported by the PCI chip during this test.

- Fix a tiny bug in WIDE negotiation that was very
  unlikely to be triggerred. The BUS width was wrongly
