9a94897a13 - Change vm_object_page_collect_flush() to assert rather than 
acquire the page queues lock.
 - Acquire the page queues lock in vm_object_page_clean().

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.

e50c4bb112 Teach /dev/kmem about direct mapped addresses. 
Note that a better solution for how to make kernacc work for direct mapped
addresses is needed for all platforms that use them.

20d1a52458 Re-add MNT_ACLS to the list of "updateable" mount flags, per our 
documentation.  Generally, you really shouldn't twiddle the flag,
but there are sensible scenarios where one might.

4cb5c6109a Use UID_ and GID_ constants instead of hard-coded numeric values

other storage devices.  Use a mode of 0640 to be consistent

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.

72aba11981 Use three UMA zones for FFS/UFS inodes instead of malloc space. 
Since inodes are currently 144 bytes, this will save 112 bytes per
