probably the right thing to do a while ago but xorg has progressed
to the point that for novice users (who are the ones expected to think
installing X11 during an install...) it's best to just install the
whole x11/xorg metaport for them. This removes the X11 sub-menus
and sets it up so you just select whether or not you want X11. While
here garbage collect an X11 configuration menu I missed removing when
I removed support for attempting xorg configuration from inside sysinstall

is probably more than the gain by not doing the two compares (the
value is almost certainly in register or at worst, cache).
Note that the uses of m_freem() are in error cases and m_freem()
handles NULL anyhow. So fast-path really isn't changed much at all.
feature is represented by a node in the new 'kern.features' sysctl node.
A feature is present if the corresponding node is present and evaluates to
true.
A FEATURE() wrapper macro is added which takes the sysctl node name and
a description of the feature as the sole arguments and creates a read-only
sysctl node with a value of 1.

Clean up DSS-related locking and protect all pertinent variables with
dss_mtx (remove dss_chunks_mtx). This fixes race conditions that could
cause chunk leaks.
Reported by: [1] kris
This is a long-standing bug, but until recent changes it was difficult
to trigger, and even then its impact was non-catastrophic, with the
exception of revision 1.157.
Optimize chunk_alloc_mmap() to avoid the need for unmapping pages in the
common case. Thanks go to Kris Kennaway for a patch that inspired this
change.
Do not maintain a record of previously mmap'ed chunk address ranges.
The original intent was to avoid the extra system call overhead in
chunk_alloc_mmap(), which is no longer a concern. This also allows some
simplifications for the tree of unused DSS chunks.
Introduce huge_mtx and dss_chunks_mtx to replace chunks_mtx. There was
no compelling reason to use the same mutex for these disjoint purposes.
Avoid memset() for huge allocations when possible.
Maintain two trees instead of one for tracking unused DSS address
ranges. This allows scalable allocation of multi-chunk huge objects in
the DSS. Previously, multi-chunk huge allocation requests failed if the
DSS could not be extended.
that I've been working on but put off committing until after the
RELENG_7 branch, including:
* New manpages: cpio.5 mtree.5
* New archive_entry_strmode()
* New archive_entry_link_resolver()
* New read support: mtree format
* Internal API change: read format auction only runs once
* Running the auction only once allowed simplifying a lot of bid logic.
* Cpio robustness: search for next header after a sync error
* Support device nodes on ISO9660 images
* Eliminate a lot of unnecessary copies for uncompressed archives
* Corrected handling of new GNU --sparse --posix formats
* Correctly handle a zero-byte write to a compressed archive
* Fixed memory leaks
Many of these improvements were motivated by the upcoming bsdcpio
front-end.
There have also been extensive improvements to the libarchive_test
test harness, which I'll commit separately.

- Mark kvm_getfiles() as broken since the live version exports struct xfile
with no filelist at the head and does so incorrectly and the deadfiles
version exports struct file with a filelist at the head. It is not known
if either version works or complies to the manpage.
- Introduce a finit() which is used to initailize the fields of struct file
in such a way that the ops vector is only valid after the data, type,
and flags are valid.
- Protect f_flag and f_count with atomic operations.
- Remove the global list of all files and associated accounting.
- Rewrite the unp garbage collection such that it no longer requires
the global list of all files and instead uses a list of all unp sockets.
- Mark sockets in the accept queue so we don't incorrectly gc them.

possible to end up in the interrupt handler again while processing the
previous RX interrupt in ifp->if_input() because the MD interrupt code
disables the delivery of the respective interrupt until all associated
handlers were called (in the INTR_FILTER case the MI code supposedly
does the same). Toggling the NIC interrupt enable bit in these handlers
still is necessary though as some chips (f.e. the VMware emulated one)
require this to be done in order to keep issuing interrupts.

insufficient free space or quota limits). But, the code does leaves the
buffers corresponding to the inoirect blocks on the vnode bufobj list.
This causes several assertion failures (for instance, "ffs_truncate3"
in ffs_truncate()) to fail, and could result in the indirect block
aliasing problem, like writing the context of such blocks to random
disk location.
Remove the buffers from the bufobj properly.
