postponing it to zfs_vget(). zfs_root() returned vnode with the
default value of v_hash, which caused inconsistent v_hash value when
root vnode was obtained from zfs_vget().
Nullfs allocated two upper vnodes for the root zfs vnode due to
different hashes, causing consistency problems.

place for the NFS-based PXE loader. Information like rootpath
or rootip aren't that useful for TFTP and the gateway IP is
typically already printed by the firmware.
2. Only set boot.nfsroot.* environment variables for NFS. This
makes it possible for the OS to work either way by checking
for the presence or absence of environment variables.
3. Set boot.netif.server when using TFTP so that the OS can fetch
files as well. A typical use case for this is network-based
installations with the installation process implemented on
top of FreeBSD.
4. The pxelinux loader has a set of alternative names it tries
for configuration files. Make it easier to do something
similar in Forth by providing the IP address as a 32-bit hex
number in the pxeboot.ip variable and the MAC address with
dashes in the pxeboot.hwaddr environment variable.

particular, allow loaders to define the name of the RC script the
interpreter needs to use. Use this new-found control to have the
PXE loader (when compiled with TFTP support and not NFS support)
read from ${bootfile}.4th, where ${bootfile} is the name of the
file fetched by the PXE firmware.
The normal startup process involves reading the following files:
1. /boot/boot.4th
2. /boot/loader.rc or alternatively /boot/boot.conf
When these come from a FreeBSD-defined file system, this is all
good. But when we boot over the network, subdirectories and fixed
file names are often painful to administrators and there's really
no way for them to change the behaviour of the loader.

so it really should not be under "optional inet". The fact that uipc_accf.c
lives under kern/ lends some weight to making it a "standard" file.
Moving kern/uipc_accf.c from "optional inet" to "standard" eliminates the
need for #ifdef INET in kern/uipc_socket.c.
Also, this meant the net.inet.accf.unloadable sysctl needed to move, as
net.inet does not exist without networking compiled in (as it lives in
netinet/in_proto.c.) The new sysctl has been named net.accf.unloadable.
In order to support existing accept filter sysctls, the net.inet.accf node
has been added netinet/in_proto.c.

underlying physical pages are mapped by the pmap. If, for example, the
application has performed an mprotect(..., PROT_NONE) on any part of the
wired region, then those pages will no longer be mapped by the pmap.
So, using the pmap to lookup the wired pages in order to unwire them
doesn't always work, and when it doesn't work wired pages are leaked.
To avoid the leak, introduce and use a new function vm_object_unwire()
that locates the wired pages by traversing the object and its backing
objects.
At the same time, switch from using pmap_change_wiring() to the recently
introduced function pmap_unwire() for unwiring the region's mappings.
pmap_unwire() is faster, because it operates a range of virtual addresses
rather than a single virtual page at a time. Moreover, by operating on
a range, it is superpage friendly. It doesn't waste time performing
unnecessary demotions.

were renamed to ARCHIVE_CRYPTO_xxx.
Rename these macros in lib/libarchive/config_freebsd.h, to re-enable the
hashes for libarchive again. This affects the mtree format writer, and
the xar format reader and writer modules.
This also requires changes in the library order for statically linking
rescue, otherwise ld would complain about redefined symbols. Thanks to
jkim for pointing out the solution.
