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.

7251782989 8255x configure command requires number of bytes of configuration
table. The default size of the configuration table was 22 bytes. To
use extended feature of 82550/82551 the configuration table size
was expanded to 32 bytes. The added configuration for 82550/82551
specifies VLAN hardware tagging and IPSec configuration as well as
TCO.
To make configuration easier fxp(4) used a configuration template
and the template was copied to configuration table. After that,
some parameters of the configuration table was changed depending on
controller type and operation mode. However the size of template
was 22 bytes so some configuration parameters were not properly
initialized on 82550/82551.
Fix this by increasing the template size. For 82557, 82558 and
82559 the size of the configuration is still 22 bytes.

a026a25b1d It seems controller has two types of promiscuous control, one for
unicast and the other for multicast. To receive multicast frames
that host didn't join in promiscuous mode, driver have to set
promiscuous mode for multicast frames as well.
The Open Source Software Developer Manual for i8255x was not clear
how to handle promiscuous mode.

e27ed89aef Merger of the quota64 project into head.
This joint work of Dag-Erling Smørgrav and myself updates the
FFS quota system to support both traditional 32-bit and new 64-bit
quotas (for those of you who want to put 2+Tb quotas on your users).

By default quotas are not compiled into the kernel. To include them
in your kernel configuration you need to specify:

options         QUOTA                   # Enable FFS quotas

If you are already running with the current 32-bit quotas, they
should continue to work just as they have in the past. If you
wish to convert to using 64-bit quotas, use `quotacheck -c 64';
if you wish to revert from 64-bit quotas back to 32-bit quotas,
use `quotacheck -c 32'.

There is a new library of functions to simplify the use of the
quota system, do `man quotafile' for details. If your application
is currently using the quotactl(2), it is highly recommended that
you convert your application to use the quotafile interface.
Note that existing binaries will continue to work.

Special thanks to John Kozubik of rsync.net for getting me
interested in pursuing 64-bit quota support and for funding
part of my development time on this project.

7024db1d40 Push down the page queues lock inside of vm_page_free_toq() and
pmap_page_is_mapped() in preparation for removing page queues locking
around calls to vm_page_free().  Setting aside the assertion that calls
pmap_page_is_mapped(), vm_page_free_toq() now acquires and holds the page
queues lock just long enough to actually add or remove the page from the
paging queues.

52683078a2 Eliminate a small bit of unneeded code from kern_sendfile(): While
kern_sendfile() is running, the file's vm object can't be destroyed
because kern_sendfile() increments the vm object's reference count.  (Once
kern_sendfile() decrements the reference count and returns, the vm object
can, however, be destroyed.  So, sf_buf_mext() must handle the case where
the vm object is destroyed.)

8c6162468b Add a helper function vm_pageout_page_lock(), similar to tegge'
vm_pageout_fallback_object_lock(), to obtain the page lock
while having page queue lock locked, and still maintain the
page position in a queue.

Use the helper to lock the page in the pageout daemon and contig launder
iterators instead of skipping the page if its lock is contested.
Skipping locked pages easily causes pagedaemon or launder to not make a
progress with page cleaning.

5ac59343be Acquire the page lock around all remaining calls to vm_page_free() on
managed pages that didn't already have that lock held.  (Freeing an
unmanaged page, such as the various pmaps use, doesn't require the page
lock.)

This allows a change in vm_page_remove()'s locking requirements.  It now
expects the page lock to be held instead of the page queues lock.
Consequently, the page queues lock is no longer required at all by callers
to vm_page_rename().
