RTC clock will remain at 32KHz and powered on, there is no need for it
at this moment.

The current implementation of the v7_coherent_*_range function assumes
that the D and I cache lines have the same size, which is incorrect
architecturally. This patch adds the icache_line_size macro which reads
the CTR register. The main loop in v7_coherent_*_range is split in two
independent loops or the D and I caches. This also has the performance
advantage that the DSB is moved outside the main loop.

The current implementation of the dcache_line_size macro reads the L1
cache size from the CCSIDR register. This, however, is not guaranteed to
be the smallest cache line in the cache hierarchy. The patch changes to
the macro to use the more architecturally correct CTR register.

sparc64 systems have a restriction in that passing in buffer
addressses above 4GB to prom calls is not reliable.
We end up violating this when we do prom console writes, because we
use an on-stack buffer to translate '\n' into '\r\n'.
So instead, do this translation into an intermediate buffer, which is
in the kernel image and thus below 4GB, then pass that to the PROM
console write calls.
On the 32-bit side we don't have to deal with any of these issues, so
the new prom_console_write_buf() uses the existing prom_nbputchar()
implementation. However we can now mark those routines static.
Since the 64-bit side completely uses new code we can delete the
putchar bits as they are now completely unused.

This gets us closer to being able to eliminate the use
of dynamic and stack based buffers, so that we can adhere
to the "no buffer addresses above 4GB" rule for PROM calls.

__pppoe_xmit function return value was invalid resulting in
additional call to kfree_skb on already freed skb. This resulted in
memory corruption and consequent kernel panic after PPPoE peer
terminated the link.
This fixes commit 55c95e738da85373965cb03b4f975d0fd559865b.

Make the LSO code work on BE platforms: parsing_data field of
a parsing BD (PBD) for 57712 was improperly composed which made FW read wrong
values for TCP header's length and offset and, as a result, the corresponding
PCI device was performing bad DMA reads triggering EEH.

Removing usage of rtnl_lock() to protect firmware interface registers.

The ATM subsystem was incorrectly creating the 'device' link for ATM
nodes in sysfs. This led to incorrect device/parent relationships
exposed by sysfs and udev. Instead of rolling the 'device' link by hand
in the generic ATM code, pass each ATM driver's bus device down to the
sysfs code and let sysfs do this stuff correctly.

Enable the port when disabling countermeasures, and disable it on
enabling countermeasures.
This bug causes the response of the system to certain attacks to be
ineffective.
It also prevents wpa_supplicant from getting scan results, as
wpa_supplicant disables countermeasures on startup - preventing the
hardware from scanning.
wpa_supplicant works with ap_mode=2 despite this bug because the commit
handler re-enables the port.
The log tends to look like:
State: DISCONNECTED -> SCANNING
Starting AP scan for wildcard SSID
Scan requested (ret=0) - scan timeout 5 seconds
EAPOL: disable timer tick
EAPOL: Supplicant port status: Unauthorized
Scan timeout - try to get results
Failed to get scan results
Failed to get scan results - try scanning again
Setting scan request: 1 sec 0 usec
Starting AP scan for wildcard SSID
Scan requested (ret=-1) - scan timeout 5 seconds
Failed to initiate AP scan.

... and interface up.
In these situations, you are usually trying to connect to a new AP, so
keeping TKIP countermeasures active is confusing. This is already how
the driver behaves (inadvertently). However, querying SIOCGIWAUTH may
tell userspace that countermeasures are active when they aren't.
Clear the setting so that the reporting matches what the driver has
done..

Fix this by making a local copy of shared skbs prior to mangeling them.
To avoid copying the skb unnecessarily move the skb_copy call below the
checks that don't need write access to the skb.
Also, move the assignment of nh_pos and h_pos below the skb_copy to point
to the correct skb.
It would be possible to avoid another resize of the copied skb by using
skb_copy_expand instead of skb_copy but that would make the patch more
complex. Also, shared skbs are a corner case right now, so the resize
shouldn't matter much.

The HW has to be set to FULLSLEEP mode during suspend,
when no interface has been brought up. Not doing this would
break resume, as the chip won't be powered up at all.

The interrupt handler takes a lock - but since commit bcad6e80f3f this
lock goes through an indirection specified in the hermes_t structure.
We must therefore initialise the structure before setting up the
interrupt handler.

The beacon tasklet is accesssing the bslot info for beacon generation.
Meanwhile the same slot can be freed on interface deletion.
Current the remove_interface disables the beacon alert after freeing the slot.
This may leads to null pointer access.
This patch disables SWBA and kills the beacon tasklet to prevent access
to the slot to be freed. After releasing the slot, swba will be enabled again
upon the availablity of beaconing interfaces.

AR_RxKeyIdxValid will not be set for bcast/mcast frames and so relying
this status for MIC failed frames is buggy.
Due to this, MIC failure events for broadcast frames are not sent to
supplicant resulted in AP disconnecting the STA.

When ath_drain_all_txq fails to stop DMA, it issues a hw reset. This reset
happens at a very problematic point in time, when the hardware rx path has
not been stopped yet. This could lead to memory corruption, hardware hangs
or other issues.
To fix these issues, simply remove the reset entirely and check the tx DMA
stop status to prevent problems with fast channel changes.

The ath9k driver subtracts 3 dBm to the txpower as with two radios the
signal power is doubled.
The resulting value is assigned in an u16 which overflows and makes
the card work at full power.

I noticed that one of the post-2.6.36 patches broke runtime PM of the
r8169 on my MSI Wind test machine in such a way that the link was not
brought up after reconnecting the network cable.
In the process of debugging the issue I realized that we only should
invoke the runtime PM functions in rtl8169_check_link_status() when
link change is reported and if we do so, the problem goes away.
Moreover, this allows rtl8169_runtime_idle() to be simplified quite
a bit.

There is definitly a problem, that some option cards send up broken
IP pakets leading to corrupted IP packets. These corruptions aren't
detected, because the driver claims that the packets are already
checksummed. This change removes the CHECKSUM_UNNECESSARY option
and let IP detect broken data.
