3c4a24406b Push down the page queues into vm_page_cache(), vm_page_try_to_cache(), and
vm_page_try_to_free().  Consequently, push down the page queues lock into
pmap_enter_quick(), pmap_page_wired_mapped(), pmap_remove_all(), and
pmap_remove_write().

Push down the page queues lock into Xen's pmap_page_is_mapped().  (I
overlooked the Xen pmap in r207702.)

Switch to a per-processor counter for the total number of pages cached.

e50d35e6c6 Add new tunable 'net.link.ifqmaxlen' to set default send interface
queue length. The default value for this parameter is 50, which is
quite low for many of today's uses and the only way to modify this
parameter right now is to edit if_var.h file. Also add read-only
sysctl with the same name, so that it's possible to retrieve the
current value.

dd48af360f Import mvs(4) - Marvell 88SX50XX/88SX60XX/88SX70XX/SoC SATA controllers
driver for CAM ATA subsystem. This driver supports same hardware as
atamarvell, ataadaptec and atamvsata drivers from ata(4), but provides
many additional features, such as NCQ, PMP, etc.

2965a45315 On Alan's advice, rather than do a wholesale conversion on a single
architecture from page queue lock to a hashed array of page locks
(based on a patch by Jeff Roberson), I've implemented page lock
support in the MI code and have only moved vm_page's hold_count
out from under page queue mutex to page lock. This changes
pmap_extract_and_hold on all pmaps.

7b85f59183 Resurrect pmap_is_referenced() and use it in mincore(). Essentially,
pmap_ts_referenced() is not always appropriate for checking whether or
not pages have been referenced because it clears any reference bits
that it encounters.  For example, in mincore(), clearing the reference
bits has two negative consequences.  First, it throws off the activity
count calculations performed by the page daemon.  Specifically, a page
on which mincore() has called pmap_ts_referenced() looks less active
to the page daemon than it should.  Consequently, the page could be
deactivated prematurely by the page daemon.  Arguably, this problem
could be fixed by having mincore() duplicate the activity count
calculation on the page.  However, there is a second problem for which
that is not a solution.  In order to clear a reference on a 4KB page,
it may be necessary to demote a 2/4MB page mapping.  Thus, a mincore()
by one process can have the side effect of demoting a superpage
mapping within another process!

530a5fb294 Improve checking whether an ARM VA has a valid mapping before performing cache
sync.

VIPT/PIPT caches need valid VA-PA mapping in PTE for a cache operation to
succeed (unlike VIVT). Prior to this fix pmap was using l2pte_valid() for that
check, but this is not sufficient as the function merely checks if a PTE
exists (there can be existing but _invalid_ entries in the table).

A new pmap_has_valid_mapping() routine is introduced to do this job right by
checking proper PTE flags.

Among other potential problems this cures coherency issues with L2 caches on
MV-78100.

066f913a94 MFp4:
Introduce ATA_CAM kernel option, turning ata(4) controller drivers into
cam(4) interface modules. When enabled, this options deprecates all ata(4)
peripheral drivers (ad, acd, ...) and interfaces and allows cam(4) drivers
(ada, cd, ...) and interfaces to be natively used instead.

As side effect of this, ata(4) mode setting code was completely rewritten
to make controller API more strict and permit above change. While doing
this, SATA revision was separated from PATA mode. It allows DMA-incapable
SATA devices to operate and makes hw.ata.atapi_dma tunable work again.

Also allow ata(4) controller drivers (except some specific or broken ones)
to handle larger data transfers. Previous constraint of 64K was artificial
and is not really required by PCI ATA BM specification or hardware.
