63a6c5c12b GEOM has an internal mechanism to deal with ENOMEM errors returned via
g_io_deliver(). In such case it increases 'pace' counter on each ENOMEM and
reschedules the request. The 'pace' counter is decreased for each request going
down, but until 'pace' is greater than zero, GEOM will handle at most 10
requests per second. For GEOM GATE users that are proxy to local GEOM providers
(like ggatel(8) and HAST) we can end up with almost permanent slow down of GEOM
down queue. This is because once we reach GEOM GATE queue limit, we return
ENOMEM to the GEOM. This means that we have, eg. 1024 I/O requests in the GEOM
GATE queue. To make room in the queue and stop returning ENOMEM we need to
proceed the requests of course, but those requests are handled by userland
daemons that handle them by reading/writing also from/to local GEOM providers.
For example with HAST, a new requests comes to /dev/hast/data, which is GEOM
GATE provider. GEOM GATE passes the request to hastd(8) and hastd(8)
reads/writes from/to /dev/da0. Once we reach GEOM GATE queue limit, to free up
a slot in GEOM GATE queue, hastd(8) has to read/write from/to /dev/da0, but
this request will also be very slow, because GEOM now slows down all the
requests. We end up with full queue that we can unload at the speed of 10
requests per second. This simply looks like a deadlock.

Fix it by allowing userland daemons that work with both GEOM GATE and local
GEOM providers to specify unlimited queue size, so GEOM GATE will never return
ENOMEM to the GEOM.

deeff310cc Overhaul locale handling.
Use locale(1) to determine the locale instead of trying to hand roll it.
Correctly construct groff call based on charset and locale independently,
not the mix between the two.

0b11462b7d A handful of the openwrt devices use a MAC address that's at a hard-coded
offset in the flash.

Some devices (eg the TPLink WR-1043ND) don't have a flash environment
partition which can be queried for the current board settings.

This particular workaround allows for image creators to use a hint
to set the base MAC address. For example:

hint.arge.0.eeprommac=0x1f01fc00

bedca8b119 Uuencode the sample "binary" firmware image file (instead of explicitly

86be754604 Fix the delete-old/check-old targets to work with arbitrarily long
OLD_FILES/OLD_DIRS/OLD_LIBS lists.

If you specify enough WITHOUT_FOO flags, the argument list passed to the
shell will be too long. Using .for/.endfor make(1) "loop" will make the
parser of the Makefile explode. Hack around this with good old pipes.

  corresponding sigreturn(2);
- implement old getpagesize(2);
- provide a user-mode trampoline and LDT call gate for lcall $7,$0;
- port a.out image activator and connect it to the build as a module
  on amd64.

The changes are hidden under COMPAT_43.

04af6e9603 GNU awk does not output escaped newlines in multi-line printc statements. This
leads to compile errors when trying to compile firmware(9) stubs created with
gawk, as multiple #include statements end up on the same line.  Replace the
multi-line printc statement that outputs all of the #includes with one printc
per #include.  This allows modules compatible with firmware(9) to be cross-built
from a Linux machine without requiring the one true awk to be installed.

I've intentionally done the minimal set of changes necessary to make gawk
produce valid (but not pretty) C code, to reduce the churn and keep fw_stubs.awk
as readable as possible.

586cb6ec77 Clearing the flag when preempting will let the preempted thread run
too much time. This can finish in a scheduler deadlock with ping-pong
between two threads.

One sample of this is:
- device lapic (to have a preemption point on critical_exit())
- options DEVICE_POLLING with HZ>1499 (to have lapic freq = hardclock freq)
- running a cpu intensive task (that does not enter the kernel)
- only one CPU on SMP or no SMP.

As requested by jhb@ 4BSD have received the same type of fix instead of
propagating the flag to the new thread.

a90dd577e7 Explicitly track the state of all known BARs for each PCI device. The PCI
bus driver will now remember the size of a BAR obtained during the initial
bus scan and use that size when doing lazy resource allocation rather than
resizing the BAR.  The bus driver will now also report unallocated BARs to
userland for display by 'pciconf -lb'.  Psuedo-resources that are not BARs
(such as the implicit I/O port resources for master/slave ATA controllers)
will no longer be listed as BARs in 'pciconf -lb'.  During resume, BARs are
restored from their new saved state instead of having the raw registers
saved and restored across resume.  This also fixes restoring BARs at
unusual loactions if said BAR has been allocated by a driver.

Add a constant for the offset of the ROM BIOS BAR in PCI-PCI bridges and
properly handle ROM BIOS BARs in PCI-PCI bridges.  The PCI bus now also
properly handles the lack of a ROM BIOS BAR in a PCI-Cardbus bridge.
