e28f5d5222 More constant renaming in preparation for newer features.
We also try to make better use of the fs flags instead of
trying adapt the code according to the fs structures. In
the case of subsecond timestamps and birthtime we now
check that the feature is explicitly enabled: previously
we only checked that the reserved space was available and
silently wrote them.

This approach is much safer, especially if the filesystem
happens to use embedded inodes or support EAs.

f8405bc4bf Busdma enhancements, especially for managing small uncacheable buffers.
- Use the new architecture-agnostic buffer pool manager that uses uma(9)
  to manage a set of power-of-2 sized buffers for bus_dmamem_alloc().

- Create pools of buffers backed by both regular and uncacheable memory,
  and use them to handle regular versus BUS_DMA_COHERENT allocations.

- Use uma(9) to manage a pool of bus_dmamap structs instead of local code
  to manage a static list of 500 items (it took 3300 maps to get to
  multi-user mode, so the static pool wasn't much of an optimization).

- Small BUS_DMA_COHERENT allocations no longer waste an entire page per
  allocation, or set pages to uncached when they contain data other than
  DMA buffers.  There's no longer a need for drivers to work around the
  inefficiency by allocing large buffers then sub-dividing them.

- Because we know the alignment and padding of buffers allocated by
  bus_dmamem_alloc() (whether coherent or regular memory, and whether
  obtained from the pool allocator or directly from the kernel) we
  can avoid doing partial cacheline flushes on them.

- Add a fast-out to _bus_dma_could_bounce() (and some comments about
  what the routine really does because the old misplaced comment was wrong).

- Everywhere the dma tag alignment is used, the interpretation is that
  an alignment of 1 means no special alignment.  If the tag is created
  with an alignment argument of zero, store it in the tag as one, and
  remove all the code scattered around that changed 0->1 at point of use.

- Remove stack-allocated arrays of segments, use a local array of two
  segments within the tag struct, or dynamically allocate an array at first
  use if nsegments > 2.  On an arm system I tested, only 5 of 97 tags used
  more than two segments.  On my x86 desktop it was only 7 of 111 tags.

05d9035003 Create an architecture-agnostic buffer pool manager that uses uma(9) to
manage a set of power-of-2 sized buffers for bus_dmamem_alloc().

This allows the caller to provide the back-end allocator uma allocator,
allowing full control of the memory pages backing the pool.  For
convenience, it provides an optional builtin allocator that provides pages
allocated with the VM_MEMATTR_UNCACHEABLE attribute, for managing pools of
DMA buffers for BUS_DMA_COHERENT or BUS_DMA_NOCACHE.

This also allows the caller to specify a minimum alignment, and it ensures
that all buffers start on a boundary and have a length that's a multiple of
that value, to avoid using buffers that trigger partial cache line flushes.

caused by use of an invalid kgss_gssd_handle during an upcall to
the gssd daemon when it has exited. This patch seems to avoid the
crashes by holding a reference count on the kgss_gssd_handle until
the upcall is done. It also adds a new mutex kgss_gssd_lock used to
make manipulation of kgss_gssd_handle SMP safe.

Also fix case where CAM_REQ_CMP was getting OR'd with CAM_DEV_NOT_THERE
in the nonexistent LUN case, resulting in different CAM status (CAM_UA_TERMIO)
getting reported to CAM.  This issue existing previously, but was more subtle
because it changed CAM_SEL_TIMEOUT to CAM_CMD_TIMEOUT.
