1ad5f80fac Revise r197763 which fixes filesystem corruption when extending
into un-zeroed storage.

The original patch was questioned by Kirk as it forces the filesystem
to do excessive work initialising inodes on first use, and was never
MFC'd.  This change mimics the newfs(8) approach of zeroing two
blocks of inodes for each new cylinder group.

a212c01aac Fix nfsrv_freeallnfslocks() in the experimental NFSv4 server so that
it frees local locks correctly upon close. In order for
nfsrv_localunlock() to work correctly, the lock can no longer be in
the lockowner's stateid list. As such, nfsrv_freenfslock() has to
be called before nfsrv_localunlock(), to get rid of the lock structure
on the lockowner's stateid list. This only affected operation when
local locks (vfs.newnfs.enable_locallocks=1) are enabled, which is
not the default at this time.

0b367bd8c0 Adopt the deferring of object deallocation for the deleted map entries
on map unlock to the lock downgrade and later read unlock operation.

System map entries cannot be backed by OBJT_VNODE objects, no need to
defer deallocation for them. Map entries from user maps do not require
the owner map for deallocation, and can be accumulated in the
thread-local list for freeing when a user map is unlocked.

Move the collection of entries for deferred reclamation into
vm_map_delete(). Create helper vm_map_process_deferred(), that is
called from locations where processing is feasible. Do not process
deferred entries in vm_map_unlock_and_wait() since map_sleep_mtx is
held.

19b8a6dbc1 kern.sched.topology_spec sysctl: use step of 1 for group levels numeration
This is just a cosmetic change for prettier output.
'indent' variable/parameter serves two purposes: it specifies whitespace
indentation level and also implies cpu group level/depth.
It would have been better to split those two uses,
but for now just a simple change.

8e860de4bf When global timer used at SMP system, update nextevent field on BSP before
sending IPI to other CPUs. Otherwise, other CPUs will try to honor stale
value, programming timer for zero interval. If timer is fast enough,
it caused extra interrupt before timer correctly reprogrammed by BSP.

a90b8833d2 Rework r210248. Although it fixed most of problems, it did not fix one
particular edge case where X-axis resolution is not multiple of font width.
Now we just advance enough scan lines, then deduct a partial scan line.
It is more intuitive than the previous code.  Apply the same wisdom to EGA
and VGA planar renderers for consistency.

1d09a9b999 Before VirtualBox is fixed, mark with #ifdef what has to be done to make
it possible to boot from ZFS RAIDZ for example from within VirtualBox.
The problem with VirtualBox is that its BIOS reports only one disk present.
If we choose to ignore this report, we can find all the disks available.
We can't have this work-around to be turned on by default, because some broken
BIOSes report true when it comes to number of disks, but present the same disk
multiple times.

ed42031102 Rearrange the TSO code to make it more readable and to clearly
separate the decision logic, of whether we can do TSO, and the
calculation of the burst length into two distinct parts.

Change the way the TSO burst length calculation is done. While
TSO could do bursts of 65535 bytes that can't be represented in
ip_len together with the IP and TCP header. Account for that and
use IP_MAXPACKET instead of TCP_MAXWIN as base constant (both
have the same value of 64K). When more data is available prevent
less than MSS sized segments from being sent during the current
TSO burst.

Add two more KASSERTs to ensure the integrity of the packets.

0b883cf6b4 Fix a couple of mps problems.
When the driver is completely saturated with commands (1024 in the
case of the SAS2008 in my test system), I/O stops.  If we tell CAM
that we have one less command slot than we have actually allocated,
everything works fine.  We also need a few extra command slots to
allow for aborts and other task management commands to be sent down.

This needs more investigation to determine the root cause, but for
now this fixes things in my testing.

mps.c:		Change a printf() to mps_printf().

mps_sas.c:	Subtract 5 command slots when we tell CAM how many
		commands we can handle.

		Add some commented-out logic to print the contents
		the CDBs for timed-out commands.  This can help
		in debugging devices that are timing out.  This
		will be uncommented once I bring some CAM changes in.
