that they add X11BASE=${LOCALBASE} to /etc/make.conf since X11BASE was
hard-wired to the now-wrong location in old releases.
However, both X11BASE and LOCALBASE have moved out of scope of src/
into ports/ now, which causes problems for upgraded users who have old
make.conf files still containing the above setting. X11BASE becomes
null and we instruct ssh and sshd to look for xauth in /bin/xauth
where it is unlikely to be found.
Instead, provide a copy of the default LOCALBASE?=/usr/local setting
here.
We also have to deal with the case where the user only overrides
LOCALBASE and doesn't set an explicit X11BASE (in ports it will be set
implicitly but not here), which will also move the location of xauth.

from the .MAKEFLAGS global variable even if it's empty or
unset. This means setting MAKEFLAGS to just an empty string
in the latter case.
If not doing so, make(1) behaved inconsistently WRT MAKEFLAGS.
In particular, it would let a `-f foo' option down to sub-makes
if .MAKEFLAGS was unset. E.g.,
env MAKEFLAGS="-f mymakefile" make
would pass `-f mymakefile' down to sub-makes via their environment
(unless mymakefile added something to .MAKEFLAGS).
But any additional options appearing would change this behaviour to
not passing `-f mymakefile' to sub-makes, as in:
env MAKEFLAGS="-f mymakefile" make -D DUMMY
or
env MAKEFLAGS="-f mymakefile -D DUMMY" make
(unless mymakefile cleared .MAKEFLAGS).
Also make(1) would leave MAKEFLAGS at its initial value if the
makefile set .MAKEFLAGS to an empty value. I.e., it was impossible
to override MAKEFLAGS with an empty value. (Note well that makefiles
are not to touch MAKEFLAGS directly, they alter .MAKEFLAGS instead.
So make(1) can filter out things such as -f when copying MAKEFLAGS
to .MAKEFLAGS at startup. Direct modifications to MAKEFLAGS just go
nowhere.)
While the original intentions of the BSD make authors are somewhat
unclear here, the bug proves that NOT passing -f options down is
the settled behaviour because the opposite behaviour is totally
unreliable in the presence of any other options. In addition, not
passing down -f's found in the environment is consistent with doing
so WRT the command line.
Update the manpage accordingly and make the whole description of
MAKEFLAGS and .MAKEFLAGS more consistent as this change indeed
brings more consistency into the reliable behaviour of make(1).

- Even for the PCI Express host controller we need to use bus 0
for configuration space accesses to devices directly on the
host controller's bus.
- Pass the maximum number of slots to pci_ocp_init() because the
caller knows how many slots the bus has. Previously a PCI or
PCI-X bus underneath a PCI Express host controller would not
be enumerated properly.
o Pull the interrupt routing logic out of pci_ocp_init() and into
its own function. The logic is not quite right and is expected
to be a bit more complex.
o Fix/add support for PCI domains. The PCI domain is the unit
number as per other PCI host controller drivers. As such, we
can use logical bus numbers again and don't have to guarantee
globally unique bus numbers. Remove pci_ocp_busnr. Return the
highest bus number ito the caller of pci_ocp_init() now that
we don't have a global variable anymore.
o BAR programming fixes:
- Non-type0 headers have at most 1 BAR, not 0.
- First write ~0 to the BAR in question and then read back its
size.

It is normally initialized by ffs_statfs() after ffs_mount finished.
The extattr autostart code calls the ufs_lookup(), that uses value above
to iterate over the directory blocks, see bmask initialization in the
ufs_lookup() and ufsdirhash. Having the filesystem with root directory
spanning more then one block would result in reading a random kernel
memory.

expressions on i386 are evaluated in the range of the long double type,
so this is wrong in a different but hopefully less worse way than
before. Since expressions are evaluated in long double registers,
there is no runtime cost to using long double instead of double to
declare intermediate values (except in cases where this avoids compiler
bugs), and by careful use of float_t or double_t it is possible to
avoid some of the compiler bugs in this area, provided these types are
declared as long double.
I was going to change float.h to be less broken and more usable in
combination with the change here (in particular, it is more necessary
to know the effective number of bits in a double_t when double_t !=
double, since DBL_MANT_DIG no longer logically gives this, and
LDBL_MANT_DIG doesn't give it either with FreeBSD-i386's default
rounding precision. However, this was too hard for now. In particular,
LDBL_MANT_DIG is used a lot in libm, so it cannot be changed. One
thing that is completely broken now is LDBL_MAX. This may have sort
of worked when it was changed from DBL_MAX in 2002 (adding 0 to it at
runtime gave +Inf, but you could at least compare with it), but starting
with gcc-3.3.1 in 2003, it is always +Inf due to evaluating it at
compile time in the default rounding precision.

mount options that mount_nfs could pass down, if it passed
down string mount options. Right now, mount_nfs jut passes
down a single mount option named "nfs_args" with a fully
initialized 'struct nfs_args'.
In future commits, we will add code to the kernel for parsing stringified
NFS mount options, so that we can convert mount_nfs to pass string options
from userspace to kernel, instead of an initialized struct nfs_args.

the same way that it is default initialized in revision 1.77 of mount_nfs.c.
Right now, this is a no-op, because currently we initialize
struct nfs_args in mount_nfs in userspace, and pass it
down into the kernel via nmount(), so we overwrite whatever we initialize
here with the value passed in from userspace.
However, this lays the groundwork for moving away from passing
struct nfs_args from userspace to kernel via nmount(), so that we
can instead pass string mount options via nmount() which can be parsed in
the kernel. This will make it easier to add new NFS mount options.

doing the MNT_RELOAD, pass in "ro" and "update"
string mount options to nmount() instead of MNT_RDONLY and MNT_UPDATE flags.
Due to the complexity of the mount parsing code especially
with respect to the root file system, passing in MNT_RDONLY and MNT_UPDATE
flags would do weird things and would cause fsck to convert the root
file system from a read-only mount to read-write.
To test:
- boot into single user mode
- show mounted file systems with: mount
- root file system should be mounted read-only
- fsck /
- show mounted file systems with: mount
- root file system should still be mounted read-only
