353adf7e7f The MI code was modified to filter the devices based on its header
type.  We know about header types 0, 1 and 2.  Ignore the rest in the
MD i386 code when we're looking for bridges.  You cannot look at the
vendor tag.  And if you don't you certainly can't look at function > 0
if the device isn't there.

The new soekris boards' GEODE cpu has issues with the old way.  This
is reported to have fixed it.

515d4440fe Add facilities for tuning the "em" driver's interrupt delays without
recompiling the driver.  See the comments near the top of "if_em.h"
for descriptions of these delays.  Four new loader tunables control
the system-wide default values:

    hw.em.tx_int_delay
    hw.em.rx_int_delay
    hw.em.tx_abs_int_delay
    hw.em.rx_abs_int_delay

The tunables are specified in microseconds.  The valid range is
0-67108 usec., and 0 means that the timer is disabled.

There are also four new sysctls (actually, a set of four for each
"em" device in the system) to query and change the interrupt delays
after the system is up:

    hw.em0.tx_int_delay
    hw.em0.rx_int_delay
    hw.em0.tx_abs_int_delay (not present for 82542/3/4 adapters)
    hw.em0.rx_abs_int_delay (not present for 82542/3/4 adapters)

It seems to be OK to change these values even while the adapter is
passing traffic.

This is controlled by a per-adapter sysctl hw.atm.hfaX.shape. When
set to 0, no shaping occures. When set to 1 at most 1 channel is

50b751a7d4 Make the driver to work with firmware version 4.1.12 (other 4.X.Y should
also do it). Three problems have been encountered:

1. The initialisation command does not work in interrupt mode. Whether
   this is a firmware bug or a feature is not clear. The original Fore
   drivers execute the initialize command always in polling mode, so
   it appears that this behaviour is expected. When we detect a 4.X.Y
   firmware do busy wait on the command status.

2. The command code of the GET_PROM command has changed. This is an
   unofficial command anyway. What was GET_PROM in 3.X.Y is CLEAR_STATS
   in 4.X.Y (although unimplemented in the firmware). We need to
   use the correct code depending on the firmware.

3. The 4.X.Y firmware can set the error flag in the command status
   without also setting the completion flag (as the documenation says).
   Check both variants.

An additional field in the per-card structure fu_ft4 is TRUE when we have
detected a 4.X.Y firmware. Otherwise it is false. The behaviour of the
driver when using a 3.X.Y firmware should be identical to the previous
behaviour.

This change will enable traffic shaping of (at least one) CBR channels.

e8d4f10982 Allocate the S/G list in the tag, not on the stack. The enforces the rule
that while many maps can exist and be loaded per tag, bus_dmamap_load() and
friends can only be called on one map at a time from the tag.  This is
enforced via the mutex arguments in the tag.

Fixing this bug means that s/g lists can be arbitrarily long in length, and
also removes an ugly GNU-ism from the code.  No API or ABI change is
incurred.  Similar changes for other platforms is forthcoming.

b053bc8407 Make sure that when the PV ENTRY zone is created in pmap, that it's
created not only with UMA_ZONE_VM but also with UMA_ZONE_NOFREE.  In
the i386 case in particular, the pmap code would hook a special
page allocation routine that allocated from kernel_map and not kmem_map,
and so when/if the pageout daemon drained the zones, it could actually
push out slabs from the PV ENTRY zone but call UMA's default page_free,
which resulted in pages allocated from kernel_map being freed to
kmem_map; bad.  kmem_free() ignores the return value of the
vm_map_delete and just returns.  I'm not sure what the exact
repercussions could be, but it doesn't look good.

In the PAE case on i386, we also set-up a zone in pmap, so be
conservative for now and make that zone also ZONE_NOFREE and
ZONE_VM.  Do this for the pmap zones for the other archs too,
although in some cases it may not be entirely necessarily.  We'd
rather be safe than sorry at this point.

Perhaps all UMA_ZONE_VM zones should by default be also
UMA_ZONE_NOFREE?

May fix some of silby's crashes on the PV ENTRY zone.

  int i386_set_ldt(int start_sel, union descriptor *descs, int num_sels);

Added Features:
o If start_sel is 0, num_sels is 1 and the descriptor pointed to by descs
  is legal, then i386_set_ldt() will allocate a descriptor and return its
  selector numbe

o If num_descs is 1, start_sels is valid, and descs is NULL, then
  i386_set_ldt() will free that descriptor (making it available to be real-
  located again later).

o If num_descs is 0, start_sels is 0 and descs is NULL then, as a special
  case, i386_set_ldt() will free all descriptors.

d56368d779 Plug a race and a leak in UMA.
1) The race has to do with zone destruction.  From the zone destructor we
   would lock the zone, set the working set size to 0, then unlock the zone,
   drain it, and then free the structure.  Within the window following the
   working-set-size set to 0 and unlocking of the zone and the point where
   in zone_drain we re-acquire the zone lock, the uma timer routine could
   have fired off and changed the working set size to something non-zero,
   thereby potentially preventing us from completely freeing slabs before
   destroying the zone (and thus leaking them).

2) The leak has to do with zone destruction as well.  When destroying a
   zone we would take care to free all the buckets cached in the zone, but
   although we would drain the pcpu cache buckets, we would not free them.
   This resulted in leaking a couple of bucket structures (512 bytes each)
   per cpu on SMP during zone destruction.

While I'm here, also silence GCC warnings by turning uma_slab_alloc()
from inline to real function.  It's too big to be an inline.

93b4c5b707 The introduction of vm object locking has caused witness to reveal
a long-standing mistake in the way a portion of a pipe's KVA is
allocated.  Specifically, kmem_alloc_pageable() is inappropriate
for use in the "direct" case because it allows a preceding vm map entry
and vm object to be extended to support the new KVA allocation.
However, the direct case KVA allocation should not have a backing
vm object.  This is corrected by using kmem_alloc_nofault().

so not only wastes memory but it can also cause a leak in zones that

fa6a7ef6e4 Process events from the ATM drivers. Carrier change and PVC change
messages are forwarded as netgraph control messages to the node
that is connected to the manage hook. If that hook is not connected,
the event is lost. Flow control events are converted to netgraph
flow control messages and send along the hook that is connected to
the flow controlled VC. ACR change events are converted to control
messages and sent along the hook for the given VC.

011a891406 Don't hide the name of tmpstk, since there is no need to do so and the
HIDENAME() macro seems to be unimplementable in C.  (HIDENAME() used
to use invalid token pasting using ## for the STDC case until gcc
started rejecting that; now it uses unportable token pasting using
juxtaposition in all cases.)  This reduces use of HIDENAME() in the
kernel to only i386 and amd64 profiling code so that it doesn't bite
most kernels whenever gcc becomes stricter.  Problems with HIDENAME()
in userland are smaller because userland mostly doesn't use strict
flags yet.  There are some advantages to hiding the name of mcount,
but newer arches shouldn't do it; only amd64 does.

On second thoughts hide tmpstk better by staticizing it.

aae962d56e Fix a problem that occurs when truncating files on NFSv3 mounts: we need
to set np->n_size back to the desired size again after calling
nfs_meta_setsize(), since it could end up in nfs_loadattrcache() getting
called, which would change n_size back to the value it had before the
truncate request was issued. The result of this bug is that the size info
cached in the nfsnode becomes incorrect, lseek(fd, ofs, SEEK_END) seeks
past the end of the file, stat() returns the wrong size, etc.

2e4a71cdb1 When exporting file descriptor data for threads invoking the
kern.file sysctl, don't return information about processes that
fail p_cansee(td, p).  This prevents sockstat and related
programs from seeing file descriptors owned by processes not
in the same jail as the thread, as well as having implications
for MAC, etc.

This is a partial solution: it permits an information leak about
the number of descriptors in the sizing calculation (but this is
not new information, you can also get it from kern.openfiles),
and doesn't attempt to mask file descriptors based on the
properties of the descriptor, only the process referencing it.
However, it provides most of what you want under most
circumstances, without complicating the locking.

c39be346e3 Changed the type of the variable `qidx' from u_int8_t to int,
mainly to quiet a warning emitted by GCC 3.3 about comparing
a variable to a value which is larger than the former can hold.

The value was checked to make sure the `np->squeue' array is
not accessed behind its boundary.
This worked due to possibly accidental truncation when
(np->squeueput + 1) was larger than or equal to MAX_START (256)
when it was assigned to `qidx'.

`qidx' is used to hold the next position in the start queue
for an insertion.  The new type was chosen because some other
code in the function ncr_freeze_devq() also uses plain integers
to hold those indices.

Wrapped the line after the closing parenthesis of an `if'
condition.

c1e97bb458 Remove __aligned(16) from the definition of struct _ia64_fpreg. It's
a non-standard construct. Instead, redefine struct _ia64_fpreg as a
union and put a long double in it. On ia64 and for LP64, this is
defined by the ABI to have 16-byte alignment. For ILP32 a long double
has 4-byte alignment, but we don't support ILP32.

Note that the in-memory image of a long double does not match the in-
memory image of spilled FP registers. This means that one cannot use
the fpr_flt field to interpet the bits. For this reason we continue
to use an aggregate type.

works differently. When a zone is limited to only one or two pages
than, on multi-cpu systems, processes can get stuck on the zonelimit,
because all remaining free items are in caches of other CPUs.

Also add rudimentary error handling in some places (panic) when a zone
cannot be created.

out of sync with the current page directory.  As a workaround, restore
%cr3 across the sleep/resume.  A more complete fix would be to undo the
lazy state and clear the pm_active bit from the borrowed pmap, but this
works and people are currently hurting.  I'll clean this up.

ECDT is not available, fall back to original probe behavior.

Other minor changes:
* Add GPE bit and GLK usage to the device announcement
* Always use the global lock in the ECDT case, but potentially downgrade to
  not using it if _GLK is 0 once the namespace is available.  This is
  announced with "Changing GLK from 1 to 0"
