95c2febd5a Rather than not redirting the bp when we get ENXIO, only redirty it
when the error is EIO.  This catches a much larger class of errors
that are unlikely to succeed if retried.

2b8395148f Update libarchive to 2.4.10. This includes a number of improvements
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.

731df5b590 - Update kvm_deadfiles to be compatible with the new system which has no
global list of all files.
 - 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.

ce18638805 Remove explicit locking of struct file.
- 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.

6c55425cdb Correct the comments in am7990_intr() and am79900_intr(); it's not
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.

implemented with macros. This patch improves code readability. Reasoning
behind vidd_* is a sort of "video discipline".

4565fa1697 Add the superpage reservation system. This is "part 2 of 2" of the
machine-independent support for superpages.  (The earlier part was
the rewrite of the physical memory allocator.)  The remainder of the
code required for superpages support is machine-dependent and will
be added to the various pmap implementations at a later date.

Initially, I am only supporting one large page size per architecture.
Moreover, I am only enabling the reservation system on amd64.  (In
an emergency, it can be disabled by setting VM_NRESERVLEVELS to 0
in amd64/include/vmparam.h or your kernel configuration file.)

c9fb56ffc8 The ffs_balloc() routines, whan allocating the indirect blocks for
the inode, do the rollback in case the allocation failed (due to
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.

c9054ae803 The limit on datasize in the install environment is 128M. That's a bit
too small for today's standards.  While loading packages sysinstall
blows past this by a LOT but I think (hope...) that's caused by other
bugs.  I'll look more into why sysinstall's memory use has gotten so
out of control as it loads packages but independent of that there really
is no reason to leave the limits on datasize and stacksize in place.  And
they can cause problems for some of the things "modern packages" might
be doing via pkg_add which gets run by sysinstall and would inherit the
limits.

Another insta-MFC probably coming, this is holding up 6.3-RC2.  Sysinstall's
memory use is so out of control it blows past the current limit before it
finishes loading either of the meta-packages kde or gnome...

c720b77ca9 Trimm out now unused option LK_EXCLUPGRADE from the lockmgr namespace.
This option just adds complexity and the new implementation no longer
will support it, so axing it now that it is unused is probabilly the
better idea.

FreeBSD version is bumped in order to reflect the KPI breakage introduced
by this patch.

In the ports tree, kris found that only old OSKit code uses it, but as
it is thought to work only on 2.x kernels serie, version bumping will
solve any problem.

15ff969441 Add the 'D' and 'M' run time options, and use them to control whether
memory is acquired from the system via sbrk(2) and/or mmap(2).  By default,
use sbrk(2) only, in order to support traditional use of resource limits.
Additionally, when both options are enabled, prefer the data segment to
anonymous mappings, in order to coexist better with large file mappings
in applications on 32-bit platforms.  This change has the potential to
increase memory fragmentation due to the linear nature of the data
segment, but from a performance perspective this is mitigated by the use
of madvise(2). [1]

Add the ability to interpret integer prefixes in MALLOC_OPTIONS
processing.  For example, MALLOC_OPTIONS=lllllllll can now be specified as
MALLOC_OPTIONS=9l.

010adfaab6 Return ESRCH when a kernel stack is queried on a process in execve() --
p_candebug() will return EAGAIN which, if the other process never
leaves execve(), will result in the sysctl spinning and never returning
to userspace.  Processes should always eventually leave execve(), but
spinning in kernel while we wait is bad for countless reasons, and
particularly harmful if execve() itself is deadlocked.

Possibly we should return another error, or return a marker indicating
the thread is in execve() so it can be reported that way in userspace.

430e46303c A partial solution to some of the 'pull the umass device with a
mounted FS' problems.  These are more along the lines of 'avoiding an
avoidable panic' than a complete solution to removable devices.  We
now close the barn door after the horse has gotten lose and has been
hit by a truck, as it were.  The barn no longer catches fire in this
case, but the horse is still dead :-).

The vfs_bio.c fix causes us not to put a failed write back into the
dirty pool if the error returned was ENXIO.  In that case, the buffer
is treated like any other clean buffer that's being retured.  ENXIO
means the device isn't there anymore and will never be there again in
the future, so retrying is futile.

The vfs_mount.c fix treats 'ENXIO' as success for unmounting a file
system.  If the device is gone, retrying later won't help and we'll
never be able to unmount the device.

These two are part of a larger patch set submitted by the author.  The
other patches will be forth coming.  I added comments to these two
patches.
