b3d1d61e31 Add exported vfs_hash_index() function, which calculates the canonical
pre-masked hash for the given vnode.  The function assumes that
vp->v_hash is initialized by the filesystem vnode instantiation
function.  At the moment, it is only done if filesystem uses
vfs_hash_insert().

960e9d02c6 Implement migration from single disk to RAID1/IRRT for Intel metadata.
Windows driver uses such migration when it creates new arrays.  While GEOM
RAID has no mechanism to implement migration in general case, this specifc
case still can be handled easily via degraded RAID1 creation followed by
regular rebuild.

1628a85079 Define VM_KMEM_SIZE_MAX as a fraction of the kernel address space size
rather than a constant so that VM_KMEM_SIZE_MAX will scale automatically
with the kernel address space size.  This is particularly important for

45e085afd6 Merge Perforce changeset 219933 and portions of 219962 (omits changes to
unmerged BERI DTS files) to head:

  Use the OFW compatible string "mips,mips4k" rather than
  "mips4k,cp0" for interrupt control using MIPS4k CP0.

  Suggested by:   thompsa

  Implement a MIPS FDT PIC decode routine to use when no PIC has been
  configured, which assumes a cascade back to the nexus bus (e.g.,
  the on-board CP0 interrupt management parts on the MIPS).  If the
  soc bus in a MIPS DTS file is declared as "mips4k,cp0"-compatible,
  then this will be enabled.  This is sufficient to allow IRQs to be
  configured on BERI.

18c527acfc Merge Perforce changeset 219925 to head:
Provided a bus_space implementation for FDT, modelled on
  bus_space_generic, but with a local version of the map address
  routine that does a P->V translation, as is the case with NLM's
  similar routine for XLP.  It's not clear to me that this is the
  right solution -- possibly this belongs in simplebus -- however,
  it is sufficient to get the DE4 LED driver working.

e17be4ba97 Merge Perforce chance 219924 to head:
In a sign of weakness, replicate the MIPS bus_space_generic.c to
  produce a new FDT version, which will perform necessary address
  space translation for bus_space -- the solution used in NLM's MIPS
  FDT support, but possibly not quite the right thing.  This is
  inconsistent with regular I/O via the nexus and the generic
  bus_space, which instead perform translation via pmap_mapdev()
  when a resource is activated.  However, it will work while I
  attempt to identify what the right way to reconcile possible
  approaches.

  (Another approach might be to make simplebus use Nexus's activate
  routine instead of a generic one?)

It is alike to RAID1, but with dedicating master and recovery disks and

This implementation is not functionaly complete comparing to Windows,
