9da1c36d0a Migrate many bus_alloc_resource() calls to bus_alloc_resource_anywhere().
Most calls to bus_alloc_resource() use "anywhere" as the range, with a given
count.  Migrate these to use the new bus_alloc_resource_anywhere() API.

77eac42e70 Create a generic PCCARD_PNP_INFO from the MODULE_PNP_INFO building
block. Use it in all the PNP drivers to export either the current PNP
table. For uart, create a custom table and export it using
MODULE_PNP_INFO since it's the only one that matches on function
number.

dd63bf99a2 Prevent overflow issues in timeout processing
Previously, any timeout value for which (timeout * hz) will overflow the
signed integer, will give weird results, since callout(9) routines will
convert negative values of ticks to '1'. For unsigned integer overflow we
will get sufficiently smaller timeout values than expected.

Switch from callout_reset, which requires conversion to int based ticks
to callout_reset_sbt to avoid this.

Also correct isci to correctly resolve ccb timeout.

This was based on the original work done by Eygene Ryabinkin
<rea@freebsd.org> back in 5 Aug 2011 which used a macro to help avoid
the overlow.

bd7f0fa0bb Reform the busdma API so that new types may be added without modifying
every architecture's busdma_machdep.c.  It is done by unifying the
bus_dmamap_load_buffer() routines so that they may be called from MI
code.  The MD busdma is then given a chance to do any final processing
in the complete() callback.

The cam changes unify the bus_dmamap_load* handling in cam drivers.

The arm and mips implementations are updated to track virtual
addresses for sync().  Previously this was done in a type specific
way.  Now it is done in a generic way by recording the list of
virtuals in the map.

fcf1c6db52 Add locking to the aic(4) driver and mark it MPSAFE.
- Move 'free_scbs' into the softc rather than having it be a global list
  and convert it to an SLIST instead of a hand-rolled linked-list.
- Use device_printf() and device_get_unit() instead of storing the unit
  number in the softc.
- Remove use of explicit bus space handles and tags.
- Don't call device_set_desc() in the pccard attach routine, instead
  set a default description during the pccard probe if the matching
  product doesn't have a name.

ff584e70fa Prepare for future integration between CAM and newbus. xpt_bus_register
now takes a device_t to be the parent of the bus that is being created.
Most SIMs have been updated with a reasonable argument, but a few exceptions
just pass NULL for now.  This argument isn't used yet and the newbus
integration likely won't be ready until after 7.0-RELEASE.

7605c12c0f 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.

7e1db24f98 The first of 3 major steps to move the CAM layer forward to using
the CAM_NEW_TRAN_CODE that has been in the tree for some years now.

This first step consists solely of adding to or correcting
CAM_NEW_TRAN_CODE pieces in the kernel source tree such
that a both a GENERIC (at least on i386) and a LINT build
with CAM_NEW_TRAN_CODE as an option will compile correctly
and run (at least with some the h/w I have).

After a short settle time, the other pieces (making
CAM_NEW_TRAN_CODE the default and updating libcam
and camcontrol) will be brought in.

This will be an incompatible change in that the size of structures
related to XPT_PATH_INQ and XPT_{GET,SET}_TRAN_SETTINGS change
in both size and content. However, basic system operation and
basic system utilities work well enough with this change.

4791f4faa9 Back out the hack from rev 1.13 that was done to initiate a bus rescan
at insert time.  When asking gibbs for approval for an MFC, this was
his reply:

1) It leaks memory if it can't allocate a path.

2) It defers allocation of aic->path until the call to scan the
   bus.  This means the path may be NULL when an interrupt occurs
   prior to the call to scan the bus (stray bus reset for instance),
   which will lead to a panic.

3) The driver in current doesn't recover from the failure to allocate
   aic->path.  The driver doesn't check during normal operation if
   the path is NULL, so again a panic will result.

4) aic_cam_rescan calls malloc with M_WAITOK.  aic_cam_rescan is called
   from attach where it isn't necessarily safe to sleep.

5) And most importantly, it co-opts the xpt_periph from the driver level.
   This was never part of the design (xpt_periph used to be static).  Making
   a call of this type may completely confuse the XPT if other XPT operations
   are ongoing.

In the long term, Justin and Warner agreed to implement solution where
CAM itself will initiate the bus rescan if a new bus is added.  For
the time being (and in particular in light of the upcoming 4.5
release), we now have camcontrol available on the boot floppy, and can
have pccardd initiate the rescan through it.
