0fe137bfcf vm_pager_put_pages() takes VM_PAGER_* flags, not OBJPC_* flags. It just
so happens that OBJPC_SYNC has the same value as VM_PAGER_PUT_SYNC so no
harm done.  But fix it :-)

1f367998c6 Allow the VM object flushing code to cluster. When the filesystem syncer
comes along and flushes a file which has been mmap()'d SHARED/RW, with
dirty pages, it was flushing the underlying VM object asynchronously,
resulting in thousands of 8K writes.  With this change the VM Object flushing
code will cluster dirty pages in 64K blocks.

Note that until the low memory deadlock issue is reviewed, it is not safe
to allow the pageout daemon to use this feature.  Forced pageouts still
use fs block size'd ops for the moment.

fe7f98e604 Change ACPI make_dev() calls to use UID_ and GID_ constants rather
than hard-coded uids and gids.

Switch the device to a group of wheel instead of operator.

Narrow down the permissions on the device to require root privilege
to manipulate the system power state.  It may be that we can broaden
access to the device after review of the access control in ACPI.

dde96893c9 Add code to ddb to allow backtracing an arbitrary thread.
(show thread {address})

Remove the IDLE kse state and replace it with a change in
the way threads sahre KSEs. Every KSE now has a thread, which is
considered its "owner" however a KSE may also be lent to other
threads in the same group to allow completion of in-kernel work.
n this case the owner remains the same and the KSE will revert to the
owner when the other work has been completed.

All creations of upcalls etc. is now done from
kse_reassign() which in turn is called from mi_switch or
thread_exit(). This means that special code can be removed from
msleep() and cv_wait().

kse_release() does not leave a KSE with no thread any more but
converts the existing thread into teh KSE's owner, and sets it up
for doing an upcall. It is just inhibitted from being scheduled until
there is some reason to do an upcall.

Remove all trace of the kse_idle queue since it is no-longer needed.
"Idle" KSEs are now on the loanable queue.

e5ac7a26a9 Define UMA_MD_SMALL_ALLOC so that uma_small_alloc and uma_small_free will
be used for zones that allocate objects of less 1 page.  The biggest advantage
of this is that all of a sudden the majority of kernel malloc-ed data doesn't
need kva allocated for it.  Besides microbenchmarks I haven't seen a measurable
performance improvement from doing this.

f546200705 Bridged packets are supplied to the firewall with their IP header
in network byte order, but icmp_error() expects the IP header to
be in host order and the code here did not perform the necessary
swapping for the bridged case. This bug causes an "icmp_error: bad
length" panic when certain length IP packets (e.g. ip_len == 0x100)
are rejected by the firewall with an ICMP response.

f6258ba488 Oops, I misread the purpose of the NULL check in EH_RESTORE() in
revision 1.62. It was checking for M_PREPEND() failing, not for the
case of a NULL mbuf pointer being supplied to the macro. Back out
that revision, and fix the NULL dereference by not calling EH_RESTORE()
in the case where the mbuf pointer is NULL because the firewall
rejected the packet.
