The Marvell bridge chips used on HighPoint SATA cards do not seem to support
the MWDMA modes (at least that could be seen in their so-called drivers :-),
so the driver needs to account for this -- to achieve this:
- add mdma_filter() method from the original patch by Bartlomiej Zolnierkiewicz
with his consent;
- install the method for all chips to only return empty mask if a SATA drive
is detected on HPT372{AN]/374 chips...

SB700 supports one physical IDE channel, but SB700 SATA controller
supports combined mode. When the SATA combined mode is enabled,
two SATA ports (port4 and port5) share one IDE channel from IDE
controller, and PATA will share the other IDE channel.
Our previous patch adding SB700 IDE device ID only supports one
IDE channel, which contains bug. The attached patch fixes the bug.

This patch adds support for powering on and off the Samsung LTV350QV LCD
panel via SPI. The driver responds to framebuffer power management, it
powers off the panel on reboot/halt/poweroff. It can also be controlled
through sysfs. The panel is powered up when the module is loaded, and off
when the module is unloaded. Verified on AVR32 STK1000.

After fixing the too small memory allocation in cr_backlight_probe()
from drivers/video/backlight/cr_bllcd.c
(commit e3bbb3f053) I noticed that the
Coverity checker also thought there were a few memory leaks in there.
I took a closer look and confirmed that there were indeed several
leaks.
At the start of the function we allocate storage for a
'struct cr_panel' and store the pointer in a variable named 'crp'.
Then we call pci_get_device() and pci_read_config_byte() and if
either of them fail we return without freeing the memory allocated
for the 'struct cr_panel'. These two leaks are easy to fix since we
don't even use 'crp' for anything up to this point, so I simply
moved the allocation further down in the function so it only happens
just before we actually need it.
A bit further down we call backlight_device_register() and store the
result in 'crp->cr_backlight_device'. In case of error we return
'crp->cr_backlight_device' from the function, thus leaking 'crp'
itself. The same thing happens with the call to lcd_device_register().
To fix these two leaks I declare two new pointers to hold the return
values, so that in case of error we can return the pointer (as before)
but without leaking 'crp'.
This version of the patch also adds missing
backlight_device_unregister() / lcd_device_unregister() / pci_dev_put()
calls to error paths.

This patch make processing netlink user -> kernel messages synchronious.
This change was inspired by the talk with Alexey Kuznetsov about current
netlink messages processing. He says that he was badly wrong when introduced
asynchronious user -> kernel communication.
The call netlink_unicast is the only path to send message to the kernel
netlink socket. But, unfortunately, it is also used to send data to the
user.
Before this change the user message has been attached to the socket queue
and sk->sk_data_ready was called. The process has been blocked until all
pending messages were processed. The bad thing is that this processing
may occur in the arbitrary process context.
This patch changes nlk->data_ready callback to get 1 skb and force packet
processing right in the netlink_unicast.
Kernel -> user path in netlink_unicast remains untouched.
EINTR processing for in netlink_run_queue was changed. It forces rtnl_lock
drop, but the process remains in the cycle until the message will be fully
processed. So, there is no need to use this kludges now.

As reported by Modestas Vainius, enabling rkfill in 1 driver and
disabling it in a second could cause a NULL pointer exception when
the rfkill-disabled driver still sets the CONFIG_SUPPORT_HW_BUTTON flag.
Furthermore, rfkill expects the timeout as a value in milliseconds
instead of jiffies. Also increase the timeout to a second,
since this 250ms would be overkill.
Also the flag DEVICE_ENABLED_RADIO_HW is causing problems
for devices which do not support the hardware button
while rfkill is enabled in the driver.
To remidy this we should inverse the flag and its meaning,
rename the flag to DEVICE_DISABLED_RADIO_HW this means that
by default the radio is enabled by the hardware button (if present)
and can only be disabled explicitely.

This needlessly wakes up processes listening for wireless events many

With the net namespaces many code leaved the __init section,
thus making the kernel occupy more memory than it did before.
Since we have a config option that prohibits the namespace
creation, the functions that initialize/finalize some netns
stuff are simply not needed and can be freed after the boot.
Currently, this is almost not noticeable, since few calls
are no longer in __init, but when the namespaces will be
merged it will be possible to free more code. I propose to
use the __net_init, __net_exit and __net_initdata "attributes"
for functions/variables that are not used if the CONFIG_NET_NS
is not set to save more space in memory.
The exiting functions cannot just reside in the __exit section,
as noticed by David, since the init section will have
references on it and the compilation will fail due to modpost
checks. These references can exist, since the init namespace
never dies and the exit callbacks are never called. So I
introduce the __exit_refok attribute just like it is already
done with the __init_refok.

[TG3]: Allow partial speed advertisement.
Honor the advertisement bitmask from ethtool. We used to always
advertise the full capability when autoneg was set to on.
changed things around so that ethtool speed settings were strictly
followed. Unfortunately ethtool doesn't seem to set ADVERTISED_Autoneg
in the advertising field (and maybe it shouldn't have to). I'd vote
that it should be fixed there, but it should also be added here just in
case someone using ethtool ioctls in their own application gets what
they want.
Adding that flag in tg3_set_settings seemed like the most logical place
since the driver works fine on boot. This is just an issue when
re-enabling autonegotiation, so we should probably nip it there.

Newer products change the way the ASIC revision is obtained. This patch
implements how the driver will extract the revision number.
This patch also adds preliminary CPMU support. CPMU stands for Central
Power Management Unit. The CPMU's role is to put the chip into lower
power states when the operating conditions allow it.

Newer tg3 devices shuffle around the registers in PCI configuration
space. This patch changes the way the driver accesses the PCI
capabilities registers. Hardcoded register locations are replaced with
offsets from pci_find_capability() return values.

When the lcs irq routine detects channel failures it drives device recovery.
After this event the device is no longer usable for shutdown requests,
because the lcs_irq routine may get wrong channel status information.
In such a case the lcs_irq routine marks the channel in 'error' state.
The channel state comes back to 'running' after restarting the channels.

if qeth_set_multicast_list() is performed on 2 CPUs in parallel,
card->ip_list may end corrupted.
Solution: In function __qeth_delete_all_mc()
remove card->ip_list entry before invoking
qeth_deregister_addr_entry(). Thus a 2nd invocation of
qeth_set_multicast_list() cannot try to remove the
same entry twice.

HiperSockets infrastructure (layer-3 mode) supports only IPv4 or
IPv6 packets. Sending other packet types disturbs TCP/IP on z/VM,
which issues messages about invalid packets.
Qeth send routine will detect packet type on sending over a
HiperSockets interface (in layer-3 mode) and drop non IP packets.
The error and drop count of the interface is incremented.

I've tried to compile 2.6.23-rc8-mm2, but it fails on ipg.c with the
error : ERROR: "__udivdi3" [drivers/net/ipg.ko] undefined!
I've instigated a bit, and I've found this code in ipg.c :
static void ipg_nic_txfree(struct net_device *dev)
{
struct ipg_nic_private *sp = netdev_priv(dev);
void __iomem *ioaddr = sp->ioaddr;
const unsigned int curr = ipg_r32(TFD_LIST_PTR_0) -
(sp->txd_map / sizeof(struct ipg_tx)) - 1;
unsigned int released, pending;
sp->txd_map is an u64
because :
dma_addr_t txd_map;
And in asm-i386/types.h, I see :
#ifdef CONFIG_HIGHMEM64G
typedef u64 dma_addr_t;
#else
typedef u32 dma_addr_t;
#endif
I my config, I use CONFIG_HIGHMEM64G
sizeof(struct ipg_tx) is an u32
So the div failed on i386 because of u64 / u32.

pasemi_mac: use buffer index pointer in clean_rx()
Use the new features in B0 for buffer ring index on the receive side. This
means we no longer have to search in the ring for where the buffer
came from.
Also cleanup the RX cleaning side a little, while I was at it.
Note: Pre-B0 hardware is no longer supported, and needs a pile of other
workarounds that are not being submitted for mainline inclusion. So the
fact that this breaks old hardware is not a problem at this time.

pasemi_mac: further performance tweaks
Misc driver tweaks for pasemi_mac:
* Increase ring size (really needed mostly on 10G)
* Take out an unneeded barrier
* Move around a few prefetches and reorder a few calls
* Don't try to clean on full tx buffer, just let things
take their course and stop the queue directly
* Avoid filling on the same line as the interface is
working on to reduce cache line bouncing
* Avoid unneeded clearing of software state (and make the
interface shutdown code handle it)
* Fix up some of the tx ring wrap logic.

pasemi_mac: add local skb alignment
Add local SKB alignment to pasemi_mac, since ppc64 in general has it at 0
because of design flaws in some of the IBM server bridge chips. However,
for PWRficient doing the unaligned copies is more expensive than doing
unaligned DMA so make sure the data is aligned instead.
