Reimplement controller-wide PM. ata_host_set_suspend/resume() are
defined to suspend and resume a host_set. While suspended, EHs for
all ports in the host_set are pegged using ATA_FLAG_SUSPENDED and
frozen.
Because SCSI device hotplug is done asynchronously against the rest of
libata EH and the same mutex is used when adding new device, suspend
cannot wait for hotplug to complete. So, if SCSI device hotplug is in
progress, suspend fails with -EBUSY.
In most cases, host_set resume is followed by device resume. As each
resume operation requires a reset, a single host_set-wide resume
operation may result in multiple resets. To avoid this, resume waits
upto 1 second giving PM to request resume for devices.
Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
Reimplement per-dev PM. The original implementation directly put the
device into suspended mode and didn't synchronize w/ EH operations
including hotplug. This patch reimplements ata_scsi_device_suspend()
and ata_scsi_device_resume() such that they request EH to perform the
respective operations. Both functions synchronize with hotplug such
that it doesn't operate on detached devices.
Suspend waits for completion but resume just issues request and
returns. This allows parallel wake up of devices and thus speeds up
system resume.
Due to sdev detach synchronization, it's not feasible to separate out
EH requesting from sdev handling; thus, ata_device_suspend/resume()
are removed and everything is implemented in the respective
libata-scsi functions.

Implement two PM per-dev EH actions - ATA_EH_SUSPEND and
ATA_EH_RESUME. Each action puts the target device into suspended mode
and resumes from it respectively.
Once a device is put to suspended mode, no EH operations other than
RESUME is allowed on the device. The device will stay suspended till
it gets resumed and thus reset and revalidated. To implement this, a
new device state helper - ata_dev_ready() - is implemented and used in
EH action implementations to make them operate only on attached &
running devices.
If all possible devices on a port are suspended, reset is skipped too.
This prevents spurious events including hotplug events from disrupting
suspended devices.

this is caused because the ns83820 driver re-enables irq flags
in hardirq context.
While legal in theory, in practice it should only be done if the
hardware is really old and has some very high overhead in its ISR.
(such as PIO IDE)
For modern hardware, running ISRs with irqs enabled is discouraged,
because 1) new hardware is fast enough to not cause latency problems
2) allowing the nesting of hardware interrupts only 'spreads out'
the handling of the current ISR, causing extra cachemisses that would
otherwise not happen. Furthermore, on architectures where ISRs share
the kernel stacks, enabling interrupts in ISRs introduces a much
higher kernel-stack-nesting and thus kernel-stack-overflow risk.
3) not managing irq-flags via the _irqsave / _irqrestore variants
is dangerous: it's easy to forget whether one function nests inside
another, and irq flags might be mismanaged.
In the few cases where re-enabling interrupts in an ISR is considered
useful (and unavoidable), it has to be taught to the lock validator
explicitly (because the lock validator needs the "no ISR ever enables
hardirqs" artificial simplification to keep the IRQ/softirq locking
dependencies manageable).
This teaching is done via the explicit use local_irq_enable_in_hardirq().
On a stock kernel this maps to local_irq_enable(). If the lock validator
is enabled then this does not enable interrupts.
Now, the analysis of drivers/net/ns83820.c's irq flags use: the
irq-enabling in irq context seems intentional, but i dont think it's
justified. Furthermore, the driver suffers from problem #3 above too,
in ns83820_tx_timeout() it disables irqs via local_irq_save(), but
then it calls do_tx_done() which does a spin_unlock_irq(),
re-enabling for a function that does not expect it! While currently
this bug seems harmless (only some debug printout seems to be
affected by it), it's nevertheless something to be fixed.
So this patch makes the ns83820 ISR irq-flags-safe, and cleans up
do_tx_done() use and locking to avoid the ns83820_tx_timeout() bug.
From: Arjan van de Ven <arjan@linux.intel.com>
ns83820_mib_isr takes the misc_lock in IRQ context. All other places that
do this in the ISR already use _irqsave versions, make this consistent at
least. At some point in the future someone should audit the driver to see
if all _irqsave's in the ISR can go away, this is generally an iffy/fragile
proposition though; for now get it safe, simple and consistent.
From: Arjan van de Ven <arjan@linux.intel.com>
ok this is a real driver deadlock:
The ns83820 driver enabled interrupts (by unlocking the misc_lock with
_irq) while still holding the rx_info.lock, which is required to be irq
safe since it's used in the ISR like this:
writel(1, dev->base + IER);
spin_unlock_irq(&dev->misc_lock);
kick_rx(ndev);
spin_unlock_irq(&dev->rx_info.lock);
This is can cause a deadlock if an irq was pending at the first
spin_unlock_irq already, or if one would hit during kick_rx().
Simply remove the first _irq solves this

[PATCH] ZyDAS ZD1211 USB-WLAN driver
There are 60+ USB wifi adapters available on the market based on the ZyDAS
ZD1211 chip.
Unlike the predecessor (ZD1201), ZD1211 does not have a hardware MAC, so most
data operations are coordinated by the device driver. The ZD1211 chip sits
alongside an RF transceiver which is also controlled by the driver. Our driver
currently supports 2 RF types, we know of one other available in a few marketed
products which we will be supporting soon.
Our driver also supports the newer revision of ZD1211, called ZD1211B. The
initialization and RF operations are slightly different for the new revision,
but the main difference is 802.11e support. Our driver does not support the
QoS features yet, but we think we know how to use them.
This driver is based on ZyDAS's own GPL driver available from www.zydas.com.tw.
ZyDAS engineers have been responsive and supportive of our efforts, so thumbs
up to them. Additionally, the firmware is redistributable and they have
provided device specs.
This driver has been written primarily by Ulrich Kunitz and myself. Graham
Gower, Greg KH, Remco and Bryan Rittmeyer have also contributed. The
developers of ieee80211 and softmac have made our lives so much easier- thanks!
We maintain a small info-page: http://zd1211.ath.cx/wiki/DriverRewrite
If there is enough time for review, we would like to aim for inclusion in
2.6.18. The driver works nicely as a STA, and can connect to both open and
encrypted networks (we are using software-based encryption for now). We will
work towards supporting more advanced features in the future (ad-hoc, master
mode, 802.11a, ...).

[PATCH] 2.6.17 missing a call to ieee80211softmac_capabilities from ieee80211softmac_assoc_req
In commit ba9b28d19a3251bb1dfe6a6f8cc89b96fb85f683, routine
ieee80211softmac_capabilities was added to ieee80211softmac_io.c. As
denoted by its name, it completes the capabilities IE that is
needed in the associate and reassociate requests sent to the
AP. For at least one AP, the Linksys WRT54G V5, the capabilities
field must set the 'short preamble' bit or the AP refuses to
associate. In the commit noted above, there is a call to the
new routine from ieee80211softmac_reassoc_req, but not from
ieee80211softmac_assoc_req. This patch fixes that oversight.
As noted in the subject, v2.6.17 is affected. My bcm43xx card had been
unable to associate since I was forced to buy a new AP. I finally was
able to get a packet dump and traced the problem to the capabilities
info. Although I had heard that a patch was "floating around", I had
not seen it before 2.6.17 was released. As this bug does not affect
security and I seem to have the only AP affected by it, there should
be no problem in leaving it for 2.6.18.

[PATCH] Convert bcm43xx-softmac to use the ieee80211_is_valid_channel routine
The current version of bcm43xx-softmac uses local routines to check
if a channel is valid. As noted in the comments, these routines do
not take any regulatory information into account. This patch converts
the code to use the equivalent routine in ieee80211, which is being
converted to know about regulatory information.

[PATCH] ieee80211: fix not allocating IV+ICV space when usingencryption in ieee80211_tx_frame
We should preallocate IV+ICV space when encrypting the frame.
Currently no problem shows up just because dev_alloc_skb aligns the
data len to SMP_CACHE_BYTES which can be used for ICV.

[PATCH] bcm43xx: workaround init_board vs. IRQ race
Place the Init-vs-IRQ workaround before any card register
access, because we might not have the wireless core mapped
at all times in init. So this will result in a Machine Check
caused by a bus error.
