* Add an extra argument to ide_max_dma_mode() for passing requested transfer
mode. Use it as an upper limit when finding the best DMA for device/host.
* Rename ide_max_dma_mode() to ide_find_dma_mode() and at the same time add
ide_max_dma_mode() wrapper which passes XFER_UDMA_6 as a requested mode to
ide_find_dma_mode(). Also add inline ide_find_dma_mode() version for
CONFIG_BLK_DEV_IDEDMA=n case.
* Pass requested transfer mode from ide_find_dma_mode() to ide_get_mode_mask()
to avoid false warning from eighty_ninty_three().
* Use ide_find_dma_mode() to limit the user requested transfer mode in
ide_rate_filter(). Also limit the requested mode by host max PIO mode.
Above changes make ide_rate_filter() to:
* Clip desired transfer mode down if it is invalid (values 0x0F, 0x13-0x19
and 0x25-0x39, values > 0x46 were already clipped down, same for values
0x25-0x39 but iff UDMA was not supported by the host).
* Clip desired transfer mode down if it is currently unsupported by IDE core
(PIO6 and MWDMA3-4, the latter were already clipped down but iff UDMA was
not supported by the host).
* Clip desired transfer mode down according to the host capabilities
(UDMA modes were already clipped down but MWDMA/SWDMA/PIO weren't,
also ->atapi_dma flag was not respected).
* Clip desired transfer mode down according to the device capabilities
(except PIO modes for now which require mode work) - shouldn't be a
problem since ide_set_xfer_rate() is called _after_ device has accepted
given transfer mode.

This is now very similar to pata_platform.c, they both use
same platform data structure and same resources.
To achieve that, byte_lanes_swapping platform data variable
and platform specified iops removed from that driver. It's fine,
since those were never used anyway.
pata_platform and ide_platform are carrying same driver names,
to easily switch between these drivers, without need to touch
platform code.

The Marvell bridge chips used on HighPoint SATA cards do not seem to support

- install the method for all chips to only return empty mask if a SATA drive

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.

IDE channel, which contains bug. The attached patch fixes the bug.

From RFC 3493, Section 5.2:
IPV6_MULTICAST_IF
Set the interface to use for outgoing multicast packets. The
argument is the index of the interface to use. If the
interface index is specified as zero, the system selects the
interface (for example, by looking up the address in a routing
table and using the resulting interface).
This patch adds support for (index == 0) to reset the value to it's
original state, allowing the system to choose the best interface. IPv4
already behaves this way.

With your description I could reproduce the bug and actually you were
completely right: the code above is incorrect. Somehow I was able to
misread RFC1122 and mixed the roles :-(:
When a connection is >>closed actively<<, it MUST linger in
TIME-WAIT state for a time 2xMSL (Maximum Segment Lifetime).
However, it MAY >>accept<< a new SYN from the remote TCP to
reopen the connection directly from TIME-WAIT state, if it:
[...]
The fix is as follows: if the receiver initiated an active close, then the
sender may reopen the connection - otherwise try to figure out if we hold
a dead connection.

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.

Both /proc/lockdep and /proc/lock_stat output may loop infinitely.
When a read() requests an amount of data smaller than the amount of data
that the seq_file's foo_show() outputs, the output starts looping and
outputs the "stuck" element's data infinitely. There may be multiple
sequential calls to foo_start(), foo_next()/foo_show(), and foo_stop()
for a single open with sequential read of the file. The _start() does not
have to start with the 0th element and _show() might be called multiple
times in a row for the same element for a given open/read of the seq_file.
Also header output should not be happening in _start(). All output should
be in _show(), which SEQ_START_TOKEN is meant to help. Having output in
_start() may also negatively impact seq_file's seq_read() and traverse()
accounting.
