Define HAVE_KERNEL_OPTION_HEADERS when building kernel and when building
modules along with kernel.
After this change it is possible to embrace opt_*.h includes with ifdef
HAVE_KERNEL_OPTION_HEADERS. And thus, avoid editing a lot of Makefiles
in modules directory each time we introduce a new opt_xxx.h.

When bridging is enabled and an ARP request is recieved on a member interface,
the arp code will search all local interfaces for a match. This triggers a
kernel log if the bridge has been assigned an address.

| Two minor optimizations of fdalloc():
|
| - if minfd < fd_freefile (as is most often the case, since minfd is
| usually 0), set it to fd_freefile.
|
| - remove a call to fd_first_free() which duplicates work already done
| by fdused().
|
| This change results in a small but measurable speedup for processes
| with large numbers (several thousands) of open files.

| The resource_xxx routines in subr_hints.c are called before and after the
| kenv environment in kern_environment.c switches to dynamic kenv. The prior
| call sets the static variable hintp to the static hints in subr_hints.c
| (hintmode==0).
|
| However, changes to the environment are not detected by the resource_xxx
| lookups after the change to dynamic kernel environment, so the lookup
| routines only report the old stuff of hintmode==0, even after the change to
| the dynamic kenv. This causes kenv users to see a different environment than
| the kernel routines.
|
| This is a problem in the mixer.c code that looks up initial mixer volume
| settings from the hints: If the hints are dynamic and not from the
| device.hints file, mixer.c doesn't see them, but kenv does.
|
| The patch from the PR (modified to comply to the style of the function)
| solves this.

Add a __packed keyword to g_eli_metadata struct definition, so
sizeof(struct g_eli_metadata) will return the exact number of bytes needed
for storing it on the disk.
Without this change GELI was unusable on amd64 (and probably other 64-bit
archs), because sizeof(struct g_eli_metadata) was greater than 512 bytes
and geli(8) was failing on assertion.

- In gem_ioctl() move the call to ether_ioctl() to the default case of
the switch statement in order to make this driver more like other
Ethernet NIC drivers.
- In gem_attach() call gem_stop() in addition to gem_reset() to make
sure the chip actually is stopped and not just reset.
- In gem_stop() also stop the gem_rint_timeout() callout in case the
driver is compiled with GEM_RINT_TIMEOUT defined.
- Remove NOP spl*() calls and add locking (making gem(4) MPSAFE).
This MFC actually brings the RELENG_6 gem(4) in line with HEAD which
means that it additionally includes a comment update regarding the
IFF_OACTIVE -> IFF_DRV_OACTIVE rename which was part of if_gem.c 1.33
but missed in the respective MFC in 1.29.2.2.

Remove mac_create_root_mount() and mpo_create_root_mount(), which
provided access to the root file system before the start of the
init process. This was used briefly by SEBSD before it knew about
preloading data in the loader, and using that method to gain
access to data earlier results in fewer inconsistencies in the
approach. Policy modules still have access to the root file system
creation event through the mac_create_mount() entry point.
Removed now, and will be removed from RELENG_6, in order to gain
third party policy dependencies on the entry point for the lifetime
of the 6.x branch.

Change all callers of fill_kinfo_thread() to call both
fill_kinfo_proc_only() and fill_kinfo() thread. When gathering

Original commit message:
FreeBSD src repository
Modified files:
sys/ufs/ffs ffs_alloc.c
Log:
Initialize the inode i_flag field in ffs_valloc() to clean up any
stale flag bits left over from before the inode was recycled.
Without this change, a leftover IN_SPACECOUNTED flag could prevent
softdep_freefile() and softdep_releasefile() from incrementing
fs_pendinginodes. Because handle_workitem_freefile() unconditionally
decrements fs_pendinginodes, a negative value could be reported at
file system unmount time with a message like:
unmount pending error: blocks 0 files -3
The pending block count in fs_pendingblocks could also be negative
for similar reasons. These errors can cause the data returned by
statfs() to be slightly incorrect. Some other cleanup code in
softdep_releasefile() could also be incorrectly bypassed.

| Fix system shutdown timeout handling by again supporting longer running
| shutdown procedures (which have a duration of more than 120 seconds).
|
| We have two user-space affecting shutdown timeouts: a "soft" one in
| /etc/rc.shutdown and a "hard" one in init(8). The first one can be
| configured via /etc/rc.conf variable "rcshutdown_timeout" and defaults
| to 30 seconds. The second one was originally (in 1998) intended to be
| configured via sysctl(8) variable "kern.shutdown_timeout" and defaults
| to 120 seconds.
|
| Unfortunately, the "kern.shutdown_timeout" was declared "unused" in 1999
| (as it obviously is actually not used within the kernel itself) and
| hence was intentionally but misleadingly removed in revision 1.107 from
| init_main.c. Kernel sysctl(8) variables are certainly a wrong way to
| control user-space processes in general, but in this particular case the
| sysctl(8) variable should have remained as it supports init(8), which
| isn't passed command line flags (which in turn could have been set via
| /etc/rc.conf), etc.
|
| As there is already a similar "kern.init_path" sysctl(8) variable which
| directly affects init(8), resurrect the init(8) shutdown timeout under
| sysctl(8) variable "kern.init_shutdown_timeout". But this time document
| it as being intentionally unused within the kernel and used by init(8).
| Also document it in the manpages init(8) and rc.conf(5).
