f0283a735c - Remove the following sysctl:
kern.sched.ipiwakeup.onecpu
  kern.sched.ipiwakeup.htt2

  Because they are absolutely obsolete. Probabilly the whole wakeup
  forward mechanism should be revisited for a better fitting in modern
  hw.
- As map2 variable is no longer used rename map3 to map2
- Fix a string by making more informative the msg and removing the
  arguments passing

f1edea81ac Add the function md_assert_nopreempt(), which is a very consistent
function on the possibility of a thread to not preempt.

As this function is very tied to x86 (interrupts disabled checkings)
it is not intended to be used in MI code.

7df304f3e0 Stop linking against a direct-mapped virtual address and instead
use the PBVM. This eliminates the implied hardcoding of the
physical address at which the kernel needs to be loaded. Using the
PBVM makes it possible to load the kernel irrespective of the
physical memory organization and allows us to replicate kernel text
on NUMA machines.

While here, reduce the direct-mapped page size to the kernel's
page size so that we can support memory attributes better.

8d3dfc2691 Add an -E option to mirror newfs's. The idea is that if you have a system
that was built before ffs grew support for TRIM, your filesystem will have
plenty of free blocks that the flash chip doesn't know are free, so it
can't take advantage of them for wear leveling.  Once you've upgraded your
kernel, you enable TRIM on the filesystem (tunefs -t enable), then run
fsck_ffs -E on it before mounting it.

I tested this patch by half-filling an mdconfig'ed filesystem image,
running fsck_ffs -E on it, then verifying that the contents were not
damaged by comparing them to a pristine copy using rsync's checksum
functionality.  There is no reliable way to test it on real hardware.

Many thanks to mckusick@, who provided the tricky parts of this patch and

0abd21bdb8 Implement BIO_DELETE for vnode devices by simply overwriting the deleted
sectors with all-zeroes.

The zeroes come from a static buffer; null(4) uses a dynamic buffer for
the same purpose (for /dev/zero).  It might be a good idea to have a
static, shared, read-only all-zeroes page somewhere in the kernel that
md(4), null(4) and any other code that needs zeroes could use.

1d29baf81e Rather than trusting that nothing is going to sneak in before the
early_late_divider in the second run (and thus be skipped altogether),
keep a list of the scripts run early, and use that list to skip things
in the second run.

This has the primary benefit of not skipping a local script that gets
ordered too early in the second run. It also gives an opportunity to
clean up/simplify the code a bit.

Use a space-separated list rather than the more traditional colon for
maximum insurance against creativity in local naming conventions.

bb82622c3e Extend the rman(9) API to support altering an existing resource.
Specifically, these changes allow a resource to back a relocatable and
resizable resource such as the I/O window decoders in PCI-PCI bridges.
- rman_adjust_resource() can adjust the start and end address of an
  existing resource.  It only succeeds if the newly requested address
  space is already free.  It also supports shrinking a resource in
  which case the freed space will be marked unallocated in the rman.
- rman_first_free_region() and rman_last_free_region() return the
  start and end addresses for the first or last unallocated region in
  an rman, respectively.  This can be used to determine by how much
  the resource backing an rman must be adjusted to accomodate an
  allocation request that does not fit into the existing rman.

While here, document the rm_start and rm_end fields in struct rman,
rman_is_region_manager(), the bound argument to
rman_reserve_resource_bound(), and rman_init_from_resource().

constraints on the rman and reject attempts to manage a region that is out
of range.
- Fix various places that set rm_end incorrectly (to ~0 or ~0u instead of
  ~0ul).
- To preserve existing behavior, change rman_init() to set rm_start and
  rm_end to allow managing the full range (0 to ~0ul) if they are not set by
  the caller when rman_init() is called.

VMware products virtualize TSC and it run at fixed frequency in so-called

calibration always gives slightly off frequency because of the complicated

672dc4aea2 TCP reuses t_rxtshift to determine the backoff timer used for both the
persist state and the retransmit timer.  However, the code that implements
"bad retransmit recovery" only checks t_rxtshift to see if an ACK has been
received in during the first retransmit timeout window.  As a result, if
ticks has wrapped over to a negative value and a socket is in the persist
state, it can incorrectly treat an ACK from the remote peer as a
"bad retransmit recovery" and restore saved values such as snd_ssthresh and
snd_cwnd.  However, if the socket has never had a retransmit timeout, then
these saved values will be zero, so snd_ssthresh and snd_cwnd will be set
to 0.

If the socket is in fast recovery (this can be caused by excessive
duplicate ACKs such as those fixed by 220794), then each ACK that arrives
triggers either NewReno or SACK partial ACK handling which clamps snd_cwnd
to be no larger than snd_ssthresh.  In effect, the socket's send window
is permamently stuck at 0 even though the remote peer is advertising a
much larger window and pending data is only sent via TCP window probes
(so one byte every few seconds).

Fix this by adding a new TCP pcb flag (TF_PREVVALID) that indicates that
the various snd_*_prev fields in the pcb are valid and only perform
"bad retransmit recovery" if this flag is set in the pcb.  The flag is set
on the first retransmit timeout that occurs and is cleared on subsequent
retransmit timeouts or when entering the persist state.
