- Static'ize sdhci_debug local to sdhci.c.
- Const'ify PCI device description strings.
- Nuke redundant resource ID members from sdhci_pci_softc.
- Nuke unused hw.sdhci_pci.debug tunable.
- Add support for using MSI instead of INTx, controllable via the tunable
  hw.sdhci.enable_msi (defaulting to on) and tested with a RICOH R5CE823 SD
  controller.
- Use NULL instead of 0 for pointers.

178b14d674 Remove ability to write to struct if_data residing in struct ifnet
via net.link.generic.IFMIB_IFDATA.*.IFDATA_GENERAL sysctl. Reasons
for removal are:
- No code in tree uses this possibility.
- The documentation ifmib(4) doesn't say that such possibility
  exist. The example provided in manual page only reads data.
- On many interfaces the feature simply doesn't work, since they
  do accounting in hardware, and overwrite if_data on tick.

4c98655ece The "SUB" instruction used in getcc() actually does 'x -= y' so use the
proper constraint for 'x'. The "+r" constraint indicates that 'x' is an
input and output register operand.

While here generate code for different variants of getcc() using a macro
GETCC(sz) where 'sz' indicates the operand size.

Update the status bits in %rflags when emulating AND and OR opcodes.

89871cdeb6 - Add a new structure type for the ACPI 3.0 SMAP entry that includes the
optional attributes field.
- Add a 'machdep.smap' sysctl that exports the SMAP table of the running
  system as an array of the ACPI 3.0 structure.  (On older systems, the
  attributes are given a value of zero.)  Note that the sysctl only
  exports the SMAP table if it is available via the metadata passed from
  the loader to the kernel.  If an SMAP is not available, an empty array
  is returned.
- Add a format handler for the ACPI 3.0 SMAP structure to the sysctl(8)
  binary to format the SMAP structures in a readable format similar to
  the format found in boot messages.

ff21e856ec First try on fixing some more compile errors without actually testing:
- use proper __FreeBSD_version check and more importantly check for __am64__
  to be defined.  Whether the FreeBSD(_version) checks are needed is a
  different question.
- cast uint64_t to uintmax_t and use %jx for printing.

Note: there are more values that could be printed in that status function
	but leave that for the future;  printf doesn't seem to be the right
	way to do it anyway.
Note: there is more breakage related to i40e_allocate_dma*() having
	conflicting declarations, so more fixes to come.

4d19f4ad1f Refactor ZFS ARC reclaim logic to be more VM cooperative
Prior to this change we triggered ARC reclaim when kmem usage passed 3/4
of the total available, as indicated by vmem_size(kmem_arena, VMEM_ALLOC).

This could lead large amounts of unused RAM e.g. on a 192GB machine with
ARC the only major RAM consumer, 40GB of RAM would remain unused.

The old method has also been seen to result in extreme RAM usage under
certain loads, causing poor performance and stalls.

We now trigger ARC reclaim when the number of free pages drops below the
value defined by the new sysctl vfs.zfs.arc_free_target, which defaults
to the value of vm.v_free_target.

Credit to Karl Denninger for the original patch on which this update was
based.
