This reworks the code for TX filtered frames, splitting it out to
a new function to handle those cases, making the clear instruction
a flag and renaming a few things to be easier to understand and
less Atheros hardware specific. Finally, it also makes the comments
explain more.Signed-off-by: Johannes Berg

enable IBSS cell merging. if an IBSS beacon with the same channel, same ESSID
and a TSF higher than the local TSF (mactime) is received, we have to join its
BSSID. while this might not be immediately apparent from reading the 802.11
standard it is compliant and necessary to make IBSS mode functional in many
cases. most drivers have a similar behaviour.* move the relevant code section (previously only containing debug code) down
to the end of the function, so we can reuse the bss structure.* we have to compare the mactime (TSF at the time of packet receive) rather
than the current TSF. since mactime is defined as the time the first data
symbol arrived we add the time until byte 24 where the timestamp resides, since
this is how the beacon timestamp is defined. as some some drivers are not able
to give a reliable mactime we fall back to use the current TSF, which will be
enough to catch most (but not all) cases where an IBSS merge is necessary.* in IBSS mode we want to allow beacons to override probe response info so we
can correctly do merges.* we don't only configure beacons based on scan results, so change that
message.* to enable this we have to let all beacons thru in IBSS mode, even if they
have a different BSSID.Signed-off-by: Bruno Randolf

define mactime as the time when the first data symbol arrived at the HW. the
old definition was questionable because 802.11 defines timestamp only for
beacon and probe response frames, and there it means the timestamp field.a stricter definition of mactime is necessary for correct merging of IBSS.
note that it is up to the driver to convert whatever its hardware returns to
this definition. unfortunately we don't know for example when atheros hardware
takes its rx timestamp exactly :(Signed-off-by: Bruno Randolf

This changes mac80211 to pass the burst time to conf_tx in txop
units rather than 0.1msec units. 0.1msec units are only required
by atheros hardware (according to current driver support), all
other drivers do other calculations or require the txop value.
Therefore, it results in fewer calculations and more precision
if we just pass the txop value through to the driver.Signed-off-by: Johannes Berg

This makes nl80211 export the hardware bitrate/channel capabilities
as registered in a wiphy.Signed-off-by: Johannes Berg
Signed-off-by: John W. Linville -
This patch creates new cfg80211 wiphy API for channel and bitrate
registration and converts mac80211 and drivers to the new API. The
old mac80211 API is completely ripped out. All drivers (except ath5k)
are updated to the new API, in many cases I expect that optimisations
can be done.Along with the regulatory code I've also ripped out the
IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be
unnecessary if the hardware simply gives us whatever channels it wants
to support and we then enable/disable them as required, which is pretty
much required for travelling.Additionally, the patch adds proper "basic" rate handling for STA
mode interface, AP mode interface will have to have new API added
to allow userspace to set the basic rate set, currently it'll be
empty... However, the basic rate handling will need to be moved to
the BSS conf stuff.I do expect there to be bugs in this, especially wrt. transmit
power handling where I'm basically clueless about how it should work.Signed-off-by: Johannes Berg

This patch allows qdisc support in A-MPDU Tx. a method to
handle QoS TID switches is present in this patch.Signed-off-by: Ron Rindjunsky
Signed-off-by: John W. Linville -
This patch adds the API for 3 stages in A-MPDU Tx session flow:
- request mac80211 to start/stop A-MPDU Tx session for specific TID. such a
request should be issued by a load aware element, either mac80211 itself
or external element.
- requests by mac80211 to low-level driver to start/stop Tx aggregation.
notice that low level driver responds now with Starting Sequence Number.
- async feedback by low-level to mac80211 to inform that HW is ready for
next A-MPDU Tx state.
Changes in API to Rx A-MPDU were also made, reflected in iwlwifi changes as
well.Signed-off-by: Ron Rindjunsky

orchid -> non-orchid addresses.Overlay Routable Cryptographic Hash IDentifiers (RFC 4843,
2001:10::/28) are currenty not globally reachable. Without this

* 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev:
libata-core: fix kernel-doc warning
sata_fsl: fix build with ATA_VERBOSE_DEBUG
[libata] ahci: AMD SB700/SB800 SATA support 64bit DMA
libata-pmp: clear hob for pmp register accesses
libata: automatically use DMADIR if drive/bridge requires it
power_state: get rid of write-only variable in SATA
pata_atiixp: Use 255 sector limit -
Back in 2.6.17-rc2, a libata module parameter was added for atapi_dmadir.
That's nice, but most SATA devices which need it will tell us about it
in their IDENTIFY PACKET response, as bit-15 of word-62 of the
returned data (as per ATA7, ATA8 specifications).So for those which specify it, we should automatically use the DMADIR bit.
Otherwise, disc writing will fail by default on many SATA-ATAPI drives.This patch adds ATA_DFLAG_DMADIR and make ata_dev_configure() set it
if atapi_dmadir is set or identify data indicates DMADIR is necessary.
atapi_xlat() is converted to check ATA_DFLAG_DMADIR before setting
DMADIR.Original patch is from Mark Lord.

Use the added dev_alloc_name() call to create tunnel device name,
rather than iterate in a hand-made loop with an artificial limit.Thanks Patrick for noticing this.

the generic code noticed the '%' in the name and invokes

Not all architectures implement futex_atomic_cmpxchg_inatomic(). The default
implementation returns -ENOSYS, which is currently not handled inside of the
futex guts.Futex PI calls and robust list exits with a held futex result in an endless
loop in the futex code on architectures which have no support.Fixing up every place where futex_atomic_cmpxchg_inatomic() is called would
add a fair amount of extra if/else constructs to the already complex code. It
is also not possible to disable the robust feature before user space tries to
register robust lists.Compile time disabling is not a good idea either, as there are already
architectures with runtime detection of futex_atomic_cmpxchg_inatomic support.Detect the functionality at runtime instead by calling
cmpxchg_futex_value_locked() with a NULL pointer from the futex initialization
code. This is guaranteed to fail, but the call of
futex_atomic_cmpxchg_inatomic() happens with pagefaults disabled.On architectures, which use the asm-generic implementation or have a runtime
CPU feature detection, a -ENOSYS return value disables the PI/robust features.On architectures with a working implementation the call returns -EFAULT and
the PI/robust features are enabled.The relevant syscalls return -ENOSYS and the robust list exit code is blocked,
when the detection fails.Fixes http://lkml.org/lkml/2008/2/11/149

Fixes a sequencing bug in spi driver pxa2xx_spi.c in which the chip select
for a transfer may be asserted before the clock polarity is set on the
interface. As a result of this bug, the clock signal may have the wrong
polarity at transfer start, so it may need to make an extra half transition
before the intended clock/data signals begin. (This probably means all
transfers are one bit out of sequence.)This only occurs on the first transfer following a change in clock polarity
in systems using more than one more than one such polarity. The fix
assures that the clock mode is properly set before asserting chip select.This bug was introduced in a patch merged on 2006/12/10, kernel 2.6.20.
The patch defines an additional bit in: include/asm-arm/arch-pxa/regs-ssp.h
for 2.6.25 and newer kernels but this addition must be made in:
include/asm-arm/arch-pxa/pxa-regs.h for kernels between 2.6.20 and 2.6.24,

inline function that had since then become a define. So while I agree with
your comments in general, in _this_ case it's pretty safe.The commit that had done it is 3062fc67dad01b1d2a15d58c709eff946389eca4
("memcontrol: move mm_cgroup to header file") and the switch to #define
is in commit 60c12b1202a60eabb1c61317e5d2678fcea9893f ("memcontrol: add
