eb36b1d0bc Clean up MD pollution of bus_dma.h:
--Remove special-case handling of sparc64 bus_dmamap* functions.
  Replace with a more generic mechanism that allows MD busdma
  implementations to generate inline mapping functions by
  defining WANT_INLINE_DMAMAP in <machine/bus_dma.h>.  This
  is currently useful for sparc64, x86, and arm64, which all
  implement non-load dmamap operations as simple wrappers
  around map objects which may be bus- or device-specific.

--Remove NULL-checked bus_dmamap macros.  Implement the
  equivalent NULL checks in the inlined x86 implementation.
  For non-x86 platforms, these checks are a minor pessimization
  as those platforms do not currently allow NULL maps.  NULL
  maps were originally allowed on arm64, which appears to have
  been the motivation behind adding arm[64]-specific barriers
  to bus_dma.h, but that support was removed in r299463.

--Simplify the internal interface used by the bus_dmamap_load*
  variants and move it to bus_dma_internal.h

--Fix some drivers that directly include sys/bus_dma.h
  despite the recommendations of bus_dma(9)

ad2b1a296f MFV r319744,r319745: 8269 dtrace stddev aggregation is normalized incorrectly
illumos/illumos-gate@79809f9cf4
79809f9cf4

https://www.illumos.org/issues/8269
  It seems that currently normalization of stddev aggregation is done
  incorrectly.
  We divide both the sum of values and the sum of their squares by the
  normalization factor. But we should divide the sum of squares by the
  normalization factor squared to scale the original values properly.

FreeBSD note: the actual change was committed in r316853, this commit
adds the test files and record merge information.

48ff53e324 aacraid: rework r315083 for a clean build with and without AACRAID_DEBUG
r315083 essentially reverted r263954 which was made for a good reason,
but didn't take into account AACRAID_DEBUG.
Now both types of build should be clean.

4195c7de24 Always null-terminate ccb_pathinq.(sim_vid|hba_vid|dev_name)
The sim_vid, hba_vid, and dev_name fields of struct ccb_pathinq are
fixed-length strings. AFAICT the only place they're read is in
sbin/camcontrol/camcontrol.c, which assumes they'll be null-terminated.
However, the kernel doesn't null-terminate them. A bunch of copy-pasted code
uses strncpy to write them, and doesn't guarantee null-termination. For at
least 4 drivers (mpr, mps, ciss, and hyperv), the hba_vid field actually
overflows. You can see the result by doing "camcontrol negotiate da0 -v".

This change null-terminates those fields everywhere they're set in the
kernel. It also shortens a few strings to ensure they'll fit within the
16-character field.

aee4341421 Remove a PCI ID for a raid controller from Adaptec that was planned,
but never released. Since no real hardware was released with this ID,
just drop it from the aacraid driver. This paves the path for future
drivers for hardware that actually has this ID.

c68534f1d5 Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI
command register.  The lazy BAR allocation code in FreeBSD sometimes
disables this bit when it detects a range conflict, and will re-enable
it on demand when a driver allocates the BAR.  Thus, the bit is no longer
a reliable indication of capability, and should not be checked.  This
results in the elimination of a lot of code from drivers, and also gives
the opportunity to simplify a lot of drivers to use a helper API to set
the busmaster enable bit.

This changes fixes some recent reports of disk controllers and their
associated drives/enclosures disappearing during boot.
