446727a7a4 Add support for the following syscalls:
- fchmod(2),
- fchown(2),
- fchflags(2),
- fstat(2),
- ftruncate(2),
- fpathconf(2),
- lpathconf(2).
Make write(2) syscall to take descriptor instead of file name.

We implement descriptors by keeping track of open files and allowing to
reference them by the following syscalls. Because pjdfstest already supports
executing multiple syscalls from one command it works pretty well.

For example, the following command:

	pjdfstest open foo "O_CREAT,O_RDWR" 0 : open bar "O_CREAT,O_RDONLY" 640 : fchmod 0 0666 : fchown 0 -1 20 : fchmod 1 0444

is equivalent of (error checking omitted):

	int fd[2];

	fd[0] = open("foo", O_CREAT | O_RDWR, 0);
	fd[1] = open("bar", O_CREAT | O_RDONLY, 0640);
	fchmod(fd[0], 0666);
	fchown(fd[0], -1, 20);
	fchmod(fd[1], 0444);

Pyun YongHyeon
d9efae0351 Rearrange dc_tx_underrun() a bit to correctly set TX FIFO threshold
value. Controllers that always require "store and forward" mode(
Davicom and PNIC 82C168) have no way to recover from TX underrun
except completely reinitializing hardware. Previously only Davicom
was reinitialized and the TX FIFO threshold was changed not to use
"store and forward" mode after reinitialization since the default
FIFO threshold value was 0. This effectively disabled Davicom
controller's "store and forward" mode once it encountered TX
underruns. In theory, this can cause watchodg timeouts.

Intel 21143 controller requires TX MAC should be idle before
changing TX FIFO threshold. So driver tried to disable TX MAC and
checked whether it saw the idle state of TX MAC. Driver should
perform full hardware reinitialization on failing to enter to idle
state and it should not touch TX MAC again once it performed full
reinitialization.

While I'm here remove resetting TX FIFO threshold to 0 when
interface is put into down state. If driver ever encountered TX
underrun, it's likely to trigger TX underrun again whenever
interface is brought to up again. Keeping old/learned TX FIFO
threshold value shall reduce the chance of seeing TX underrns in
next run.

program that uses pwlib.

Strip any leading slashes before feeding the label to the geom_label code.

48c1d36479 Implement open-loop TX power control (OLC) for Merlin (AR9280) and
generally tidy up the TX power programming code.

Enforce that the TX power offset for Merlin is -5 dBm, rather than
any other value programmable in the EEPROM. This requires some
further code to be ported over from ath9k, so until that is done
and tested, fail to attach NICs whose TX power offset isn't -5
dBm.

This improves both legacy and HT transmission on my merlin board.
It allows for stable MCS TX up to MCS15.

Specifics:

* Refactor out a bunch of the TX power calibration code -
  setting/obtaining the power detector / gain boundaries,
  programming the PDADC
* Take the -5 dBm TX power offset into account on Merlin -
  "0" in the per-rate TX power register means -5 dBm, not
  0 dBm
* When doing OLC
* Enforce min (0) and max (AR5416_MAX_RATE_POWER) when fiddling
  with the TX power, to avoid the TX power values from wrapping
  when low.
* Implement the 1 dBm cck power offset when doing OLC
* Implement temperature compensation for 2.4ghz mode when doing OLC
* Implement an AR9280 specific TX power calibration routine which
  includes the OLC twiddles, leaving the earlier chipset path
  (AR5416, AR9160) alone

Whilst here, use these refactored routines for the AR9285 TX power
calibration/programming code and enforce correct overflow/underflow
handling when fiddling with TX power values.

Preserving $? may cause problems particularly if set -e is in effect.

It may be useful to preserve the old value of $? in the dot script but this
must not be implemented in such a way that it would break this test.

8587289fb8 The UFS dirhash code was attempting to update shared state in the dirhash
from multiple threads while holding a shared lock during a lookup operation.
This could result in incorrect ENOENT failures which could then be
permanently stored in the name cache.

Specifically, the dirhash code optimizes the case that a single thread is
walking a directory sequentially opening (or stat'ing) each file.  It uses
state in the dirhash structure to determine if a given lookup is using the
optimization.  If the optimization fails, it disables it and restarts the
lookup.  The problem arises when two threads both attempt the optimization
and fail.  The first thread will restart the loop, but the second thread
will incorrectly think that it did not try the optimization and will only
examine a subset of the directory entires in its hash chain.  As a result,
it may fail to find its directory entry and incorrectly fail with ENOENT.

To make this safe for use with shared locks, simplify the state stored in
the dirhash and move some of the state (the part that determines if the
current thread is trying the optimization) into a local variable.  One
result is that we will now try the optimization more often.  We still
update the value under the shared lock, but it is a single atomic store
similar to i_diroff that is stored in UFS directory i-nodes for the
non-dirhash lookup.
