rather than unconditionally making partially dirty pages fully dirty, only
make partially dirty pages fully dirty if the pmap says that the page has
been modified.
(This change is also a small optimization. It eliminate an unnecessary call
to pmap_is_modified() on pages that are mapped read only.)

The hypervisor doesn't provide a single "TOD" - it instead provides a
"start time" and a "running time". These are added together to form
the current TOD. The TOD is in UTC.
This RTC is only (initially) designed to be read at startup. There's
some further poking that needs to happen to pick up hypervisor time
changes (ie, by the Dom0 time being adjusted by something). This
time adjustment currently can cause "weird stuff" in the DomU clock;
I'll begin investigating and repairing that in subsequent commits.

I'm not sure what series of events is leading up to this watch event
being received with no callback info and it should be investigated.
I'm triggering it somehow by registering an RTC device (which will
show up in a subsequent commit.)
regular one. It now takes a "-4" command line argument to force it
to use the experimental server. Otherwise it will use the regular
server unless the experimental server is the only one linked into
the kernel. A third kind of line has been added to /etc/exports,
which is specific to NFSv4 and defines where the NFSv4 tree root is
and can be used to limit access to NFSv4 state handling operations
that do not use any file handle.

Calculate the exact number of vectors we'll use before calling
pci_alloc_msix. Don't grab nine all the time.
Call cxgb_setup_interrupts once per T3, not once per port. Ditto

Don't leak resources when interrupt setup fails in the middle.

experimental client is used when the fstype is "newnfs" or the "nfsv4"
option is specified. It includes the addition of the option:
gssname - to specify a client side initiator host based principal name
which is specific to NFSv4.
It also includes a change to mount.c, so that it knows about
mount_newnfs, but not mount_nfs4.

Last year I added SLIST_REMOVE_NEXT and STAILQ_REMOVE_NEXT, to remove
entries behind an element in the list, using O(1) time. I recently
discovered NetBSD also has a similar macro, called SLIST_REMOVE_AFTER.
In my opinion this approach is a lot better:
- It doesn't have the unused first argument of the list pointer. I added
this, mainly because OpenBSD also had it.
- The _AFTER suffix makes a lot more sense, because it is related to
SLIST_INSERT_AFTER. _NEXT is only used to iterate through the list.
The reason why I want to rename this now, is to make sure we don't
release a major version with the badly named macros.
- add key mappings for fn keys
- byte swapping for certain models
- Fix leds for keyboards which require an ID byte for the HID output structures

ip6_input.c, in6.h:
* Add netinet6-specific mbuf flag M_RTALERT_MLD, shadowing M_PROTO6.
* Always set this flag if HBH Router Alert option is present for MLD,
even when not forwarding.
icmp6.c:
* In icmp6_input(), spell m->m_pkthdr.rcvif as ifp to be consistent.
* Use scope ID for verifying input. Do not apply SSM filters here, no inpcb.
* Check for M_RTALERT_MLD when validating MLD traffic, as we can't see
IPv6 hop options outside of ip6_input().
in6_mcast.c:
* Use KAME scope/zone ID in in6_multi.
* Update net.inet6.ip6.mcast.filters implementation to use scope IDs
for comparisons.
* Fix scope ID treatment in multicast socket option processing.
Scope IDs passed in from userland will be ignored as other less
ambiguous APIs exist for specifying the link.
* Tighten userland input checks in IPv6 SSM delta and full-state ops.
* Source filter embedded scope IDs need to be revisited, for now
just clear them and ignore them on input.
* Adapt KAME behaviour of looking up the scope ID in the default zone
for multicast leaves, when the interface is ambiguous.
mld6.c:
* Tighten origin checks on MLD traffic as per RFC3810 Section 6.2:
* ip6_src MAY be the unspecified address for MLDv1 reports.
* ip6_src MAY have link-local address scope for MLDv1 reports,
MLDv1 queries, and MLDv2 queries.
* Perform address field validation *before* accepting queries.
* Use KAME scope/zone ID in query/report processing.
* Break const correctness for mld_v1_input_report(), mld_v1_input_query()
as we temporarily modify the input mbuf chain.
* Clear the scope ID before handoff to userland MLD daemon.
* Fix MLDv1 old querier present timer processing.
With the protocol defaults, hosts should revert to MLDv2 after 260s.
* Add net.inet6.mld.v1enable sysctl, default to on.
ifmcstat.c:
* Use sysctl by default; -K requests kvm(3) if so compiled.
mld.4:
* Connect man page to build.
Tested using PCS.
Once AP's are launched, their MCA state information is stored and later obtainable using a sysctl. Since the size of the MCA state information is unknown, it will be malloc'ed as needed. However, when 'ia64_ap_startup' runs, it's not yet safe to call malloc and this may cause 'panic: blockable sleep lock (sleep mutex) 8192 @ /usr/src/sys/vm/uma_core.c'. This commit avoids this issue by scheduling a separate kthread to obtain this information, which immediately terminates afterwards.
This version is now licensed under a 2-clause BSD license, instead of
the Artistic license. I've reverted a lot of local modifications we made
to ee, because they have been integrated upstream as well.
Only local modifications include:
- $FreeBSD$ ID.
- Pathname to init.ee.
- catopen() call, to honor LC_MESSAGES instead of LANG.
To keep SVN happy, I'm putting an application/octet-stream mime type on
the KOI8 translations.

and jail_get(2). Jail(8) can now create jails using a "name=value"
format instead of just specifying a limited set of fixed parameters; it
can also modify parameters of existing jails. Jls(8) can display all
parameters of jails, or a specified set of parameters. The available
parameters are gathered from the kernel, and not hard-coded into these
programs.
Small patches on killall(1) and jexec(8) to support jail names with

by creating a child jail, which is visible to that jail and to any
parent jails. Child jails may be restricted more than their parents,
but never less. Jail names reflect this hierarchy, being MIB-style
dot-separated strings.
Every thread now points to a jail, the default being prison0, which
contains information about the physical system. Prison0's root
directory is the same as rootvnode; its hostname is the same as the
global hostname, and its securelevel replaces the global securelevel.
Note that the variable "securelevel" has actually gone away, which
should not cause any problems for code that properly uses
securelevel_gt() and securelevel_ge().
Some jail-related permissions that were kept in global variables and
set via sysctls are now per-jail settings. The sysctls still exist for
backward compatibility, used only by the now-deprecated jail(2) system
call.

of ip_forward(), if the IPSEC is compiled in. It is possible that there
is an SPD that this packets will go through, even if there is no matching
route. If not, ICMP will be sent anyway, after ip_output().
This is somewhat similar in purpose to r191621, except that one was
for the packets sent from the host, while this one is for packets
being forwarded by the host.
