405b925e39 Don't disable PCIe just because the host is not a PCI host; the latter flag
only applies to non-PCIe systems.  If PCIe is in target mode, it will simply
and gracefully fail to attach of its own accord.

1f51baaa92 Use Simple Executive LED display routines, which correctly use the LED base
address passed from the bootloader, rather than using a hard-coded value.

Make FreeBSD announce itself on the LED display similar to other kernels.

Remove uses of the previous LED routines, which were under-used and only used
in drivers for what seem like debugging purposes, despite those drivers being
widely-tested.

Remove several inlines for accessing memory that duplicate other functions
which are now used instead, as they are now entirely unused.

a42ac676f5 Disconnect non-MPSAFE NTFS from the build in preparation for dropping
GIANT from VFS. This code is particulary broken and fragile and other
in-kernel implementations around, found in other operating systems,
don't really seem clean and solid enough to be imported at all.
If someone wants to reconsider in-kernel NTFS implementation for
inclusion again, a fair effort for completely fixing and cleaning it
up is expected.

In the while NTFS regular users can use FUSE interface and ntfs-3g
port to work with their NTFS partitions.

This is not targeted for MFC.

312188ac4a Optimize the TLB invalidations performed by pmap_protect(). Use the new
range-based invalidation function instead of performing per-page

948aea4031 Correct two pessimizations in pmap_extract_and_hold(). Test the PTE for
having PTE_RO set instead of PTE_D.  This avoids some unnecessary failures
by pmap_extract_and_hold() that will have to be handled by a call to
vm_fault_hold().  Testing the PTE for both being non-zero and having PTE_V
set is redundant.  The latter suffices.

7336315b0a Simplify pmap_unmapdev(). Since kmem_free() eventually calls pmap_remove(),
pmap_unmapdev()'s own direct efforts to destroy the page table entries are
redundant, so eliminate them.

Don't set PTE_W on the page table entry in pmap_kenter{,_attr}() on MIPS.
Setting PTE_W on MIPS is inconsistent with the implementation of this
function on other architectures.  Moreover, PTE_W should not be set, unless
the pmap's wired mapping count is incremented, which pmap_kenter{,_attr}()
doesn't do.

1c978ec48b pmap_remove:
Avoid re-walking the page table from the root for every PTE examined.

  Tidy up some of pmap_remove()'s helper functions.

pmap_enter:

  Set PV_TABLE_REF whenever the physical page being mapped is managed, not
  just when it is writeable.

  Only call pmap_update_page() when the old mapping was valid.  If there was
  no prior valid mapping, then pmap_update_page() serves no useful purpose.
  However, it will interrupt every processor that has the pmap active.

pmap_enter_quick_locked:

  Always set PTE_RO.

pmap_emulate_modified:

  Don't set PV_TABLE_REF.

  Eliminate a nonsensical comment.

d8f9ed32c5 Rename {_,}pmap_unwire_pte_hold() to {_,}pmap_unwire_ptp() and update the
comment describing them.  Both the function names and the comment had grown
stale.  Quite some time has passed since these pmap implementations last
used the page's hold count to track the number of valid mapping within a
page table page.  Also, returning TRUE from pmap_unwire_ptp() rather than
_pmap_unwire_ptp() eliminates a few instructions from callers like
pmap_enter_quick_locked() where pmap_unwire_ptp()'s return value is used
directly by a conditional statement.
