ath5k: disable ASPM L0s for all cards
Atheros PCIe wireless cards handled by ath5k do require L0s disabled.
For distributions shipping with CONFIG_PCIEASPM (this will be enabled
by default in the future in 2.6.36) this will also mean both L1 and L0s
will be disabled when a pre 1.1 PCIe device is detected. We do know L1
works correctly even for all ath5k pre 1.1 PCIe devices though but cannot
currently undue the effect of a blacklist, for details you can read
pcie_aspm_sanity_check() and see how it adjusts the device link
capability.
It may be possible in the future to implement some PCI API to allow
drivers to override blacklists for pre 1.1 PCIe but for now it is
best to accept that both L0s and L1 will be disabled completely for
distributions shipping with CONFIG_PCIEASPM rather than having this
issue present. Motivation for adding this new API will be to help
with power consumption for some of these devices.
Example of issues you'd see:
- On the Acer Aspire One (AOA150, Atheros Communications Inc. AR5001
Wireless Network Adapter [168c:001c] (rev 01)) doesn't work well
with ASPM enabled, the card will eventually stall on heavy traffic
with often 'unsupported jumbo' warnings appearing. Disabling
ASPM L0s in ath5k fixes these problems.
- On the same card you would see a storm of RXORN interrupts
even though medium is idle.

Bluetooth: Use 3-DH5 payload size for default ERTM max PDU size
The previous value of 672 for L2CAP_DEFAULT_MAX_PDU_SIZE is based on
the default L2CAP MTU. That default MTU is calculated from the size
of two DH5 packets, minus ACL and L2CAP b-frame header overhead.
ERTM is used with newer basebands that typically support larger 3-DH5
packets, and i-frames and s-frames have more header overhead. With
clean RF conditions, basebands will typically attempt to use 1021-byte
3-DH5 packets for maximum throughput. Adjusting for 2 bytes of ACL
headers plus 10 bytes of worst-case L2CAP headers yields 1009 bytes
of payload.
This PDU size imposes less overhead for header bytes and gives the
baseband the option to choose 3-DH5 packets, but is small enough for
ERTM traffic to interleave well with other L2CAP or SCO data.
672-byte payloads do not allow the most efficient over-the-air
packet choice, and cannot achieve maximum throughput over BR/EDR.

remote_tx_win is intended to be set on receipt of an L2CAP

An incorrect remote_tx_win value will cause the stack to not fully

tx window (causing dropped frames or a disconnect).

iwlagn: fix rts cts protection
Currently the driver will try to protect all frames,
which leads to a lot of odd things like sending an
RTS with a zeroed RA before multicast frames, which
is clearly bogus.
In order to fix all of this, we need to take a step
back and see what we need to achieve:
* we need RTS/CTS protection if requested by
the AP for the BSS, mac80211 tells us this
* in that case, CTS-to-self should only be
enabled when mac80211 tells us
* additionally, as a hardware workaround, on
some devices we have to protect aggregated
frames with RTS
To achieve the first two items, set up the RXON
accordingly and set the protection required flag
in the transmit command when mac80211 requests
protection for the frame.
To achieve the last item, set the rate-control
RTS-requested flag for all stations that we have
aggregation sessions with, and set the protection
required flag when sending aggregated frames (on
those devices where this is required).
Since otherwise bugs can occur, do not allow the
user to override the RTS-for-aggregation setting
from sysfs any more.
Finally, also clean up the way all these flags get
set in the driver and move everything into the
device-specific functions.

and data are in different descriptors. If the reads go out of order
we may have data that doesn't match the TCP/IP header. Since we use
hardware checksumming this bad data is never verified and it makes it
all the way to the application.
This bug was found during stress testing and adding this barrier has
been shown to fix it. The bug can manifest as a data integrity issue
(bad payload data) or as a BUG in skb_pull().
This was a nasty bug to hunt down, if people agree with the fix I think
it's a candidate for stable.

ixgbe: fix build error with FCOE_CONFIG without DCB_CONFIG
Building ixgbe without DCB_CONFIG and FCOE_CONFIG will cause
a build error. This resolves the build error by wrapping
the fcoe.up in CONFIG_IXGBE_DCB ifdefs.
Also frames were being priority VLAN tagged even without DCB
enabled. This fixes this so that 8021Q priority tags are
only added with DCB actually enabled.

This patch uses an RCU-inspired approach to fix it. In the RX tasklet's
find_vcc() function we first refuse to use a VCC which already has the
ATM_VF_READY bit cleared. And in the VCC close function, we synchronise
with the tasklet to ensure that it can't still be using the VCC before
we continue and allow the VCC to be destroyed.

RxRPC: Fix a potential deadlock between the call resend_timer and state_lock
RxRPC can potentially deadlock as rxrpc_resend_time_expired() wants to get
call->state_lock so that it can alter the state of an RxRPC call. However, its
caller (call_timer_fn()) has an apparent lock on the timer struct.
The problem is that rxrpc_resend_time_expired() isn't permitted to lock
call->state_lock as this could cause a deadlock against rxrpc_send_abort() as
that takes state_lock and then attempts to delete the resend timer by calling
del_timer_sync().
The deadlock can occur because del_timer_sync() will sit there forever waiting
for rxrpc_resend_time_expired() to return, but the latter may then wait for
call->state_lock, which rxrpc_send_abort() holds around del_timer_sync()...
This leads to a warning appearing in the kernel log that looks something like
the attached.
It should be sufficient to simply dispense with the locks. It doesn't matter
if we set the resend timer expired event bit and queue the event processor
whilst we're changing state to one where the resend timer is irrelevant as the
event can just be ignored by the processor thereafter.

ath9k_hw: Fix regulatory CTL index usage for AR9003
AR9003 was not relying on the CTL indexes from the EEPROM for capping the
max output power. The CTL indexes from the EEPROM provide calibrated
limits for output power for each tested and supported frequency. Without
this the device operates at a power level which only conforms to the
transmit spectrum mask as specified by IEEE Annex I.2.3.
The regulatory limit by CRDA is always used but does not provide
calibrated values for optimal performance, specially on band edges.
Using the calibrated data from the EEPROM ensures the device
operates at optimal output power while still ensuring proper
regulatory compliance. The device uses the minimum of these tree
values, the value from CRDA, the calibrated value from CTL indexex,
and the value to conform to the IEEE transmit spectrum mask.

The noise floor history buffer is currently not kept per channel, which
can lead to problems when changing channels from a clean channel to a
noisy one. Also when switching from HT20 to HT40, the noise floor
history buffer is full of measurements, but none of them contain data
for the extension channel, which it needs quite a bit of time to recover
from.
This patch puts all the per-channel calibration data into a single data
structure, and gives the the driver control over whether that is used
per-channel or even not used for some channels.
For ath9k_htc, I decided to keep this per-channel in order to avoid
creating regressions.
For ath9k, the data is kept only for the operating channel, which saves
some space. ath9k_hw takes care of wiping old data when the operating

Previously the software scan callback was used to indicate to the hardware,

Also, software scans are not the only thing that triggers off-channel

this and not use the software scan callback for anything calibration related.

multiple parallel open attempts to continue doesn't gain anything as
those are serialized down in the call chain anyway. Fix it by always
allowing only single open attempt in a claiming block.
This problem can easily be reproduced by adding a delay after
bd_prepare_to_claim() and attempting to mount two partitions of a
disk.

parisc: pass through '\t' to early (iodc) console
The firmware handles '\t' internally, so stop trying to emulate it
(which, incidentally, had a bug in it.)
Fixes a really weird hang at bootup in rcu_bootup_announce, which,
as far as I can tell, is the first printk in the core kernel to use
a tab as the first character.
