51200f9b7c Take the same approach for i386 as that for ia64 and amd64. Use
the userland version of [gs]etcontext to switch between a thread
and the UTS scheduler (and back again).  This also fixes a bug
in i386 _thr_setcontext() which wasn't properly restoring the
context.

This removes the need to #include <vm/swap_pager.h> which is due to

130316479a Improve consistency with the Biba policy -- rename
mac_mls_subject_equal_ok() to mac_mls_subject_privileged(),
which more consistently reflects the fact that this is really
about our notion of privilege in the MLS policy.

Since we don't use suser() for privilege in MLS, remove
the suser check from the ifnet relabel ioctl, and replace it
with an MLS privilege check.

1beccae67c Add a new function to look for a spinlock's instance when it is held by
another thread.  We use the td_oncpu member of the other field to locate
it's associated CPU and then search the that CPU's list of spin locks
contained in its per-CPU data.  This is not always safe and may in fact
panic or just not work, but it is useful in at least one case.

1e16f6098b Add a one-shot callout facility to db_printf() that executes the registered
callout when a specified number of lines have been output.  This can be
used to implement pagers for ddb commands that output a lot of text.  A
simple paging function is included that automatically rearms itself when
fired.

bec064b151 Implement a traffic shaping option for the PCA200 for CBR channels.
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
shaped. When set to 2 all CBR channels are shaped. Note, that the
latter may actually not work, because of the adapter supporting
the shaping of only one PDU at the same time.

fac5c31769 Make firmware version 4.1.12 the default for download to PCA-200E adapters.
The old firmware (3.0.1) can still be used by specifying the '-3' option
to fore_dnld.

Document the -r option that resets the adapter prior to the download.

Ther newer firmware version allows traffic shaping.

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.

dae8d52de5 Enhance i386_set_ldt to allow application to dynamic allocate
or free a LDT entry. The function has following prototype:
  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.
