There is still much work needed, but I wanted to give Wei the credit
he deserves. I've merged some of my own fixes already, to make
gcc and checkpatch happy. Individual fixes and improvements from me
will follow.
[JD: Fix build errors]
[JD: Coding style cleanups]
[JD: Get rid of forward declarations]
[JD: Drop VID support]
[JD: Drop fault output control feature]
[JD: Use lowercase for inline function names]
[JD: Use strict variants of the strtol/ul functions]
[JD: Shorten the read and write function names]

This way we don't need to modify Kconfig every time a new SoC comes along to
make this driver support it. Also fix some typos while I'm at it.

consider using strict_strtol in preference to simple_strtol.
Also we should not allow any partially numeric values.

Along the same lines as "cxgb4: fix crash due to manipulating queues
before registration" (8f6d9f40476895571df039b6f1f5230ec7faebad), before
commit "net: allocate tx queues in register_netdevice"
netif_tx_stop_all_queues and related functions could be used between
device allocation and registration but now only after registration.
cxgb4 has such a call before registration and crashes now. Move it
after register_netdev.

The __NS8390_init tries to start the device queue before the

This happens because the netif_start_queue sets respective bit on the dev->_tx
array which is not yet allocated.
As far as I understand the code removing the netif_start_queue from __NS8390_init
is OK, since queue will be started later on device open. Plz, correct me if I'm wrong.

The DCB credits refill quantum _must_ be greater than half the max
packet size. This is needed to guarantee that TX DMA operations
are not attempted during a pause state. Additionally, the min IFG
must be set correctly for DCB mode. If a DMA operation is
requested unexpectedly during the pause state the HW data
store may be corrupted leading to a DMA hang. The DMA hang
requires a reset to correct. This fixes the HW configuration
to avoid this condition.

Some errors can be induced in the PHY via environmental testing

Now that the roundup macro is sane, it can't be used in structure

This patch removes the controller overlap between cciss and hpsa. It was
decided that no overlap should exist. All new controllers will use the hpsa
SCSI based driver.

Structure IOCTL_Command_struct is copied to userland with
some padding fields at the end of the struct unitialized.
It leads to leaking of contents of kernel stack memory.

As described in https://bugzilla.kernel.org/show_bug.cgi?id=19922
: I had an AoE device go down overnight, and while a server was trying to
: write to it, it was also writing this message to its logs:
:
: 209 printk(KERN_INFO "aoe: device %ld.%d is not up\n",
: 210 d->aoemajor, d->aoeminor);
:
: The message appeared many times per second, and over several hours
: produced about 7.5 gigabytes of log files, filling up all free space on
: the root filesystem.

If CONFIG_LBDAF=y, `sector_t' becomes `u64' instead of `unsigned long':
drivers/block/z2ram.c: In function ¡do_z2_request¢:
drivers/block/z2ram.c:83: warning: format %lu expects type `long unsigned int', but argument 2 has type `sector_t'
Hence always cast it to `unsigned long long' for printing. Also do the
pr_err() dance, while we're at it.

flush_scheduled_work() is deprecated and scheduled to be removed.
Directly cancel aoedev->work on free instead of depending on
flush_scheduled_works().

Very recently, the RS485 interface has been fixed by adding two further
fields (see commit 1b6331848b69d1ed165a6bdc75c4046d68767563).
Check the value of the flag SER_RS485_RTS_BEFORE_SEND before delaying.

(Updated to address Ben's comments. With regard to the message segment
restriction it's not something we hit on the actual platform so while
I will investigate that further I don't think its a blocker to submission.
At worst its a spot over-restrictive)
From: Wen Wang <wen.w.wang@intel.com>
Initial release of the driver. Updated and verified on hardware.
Cleaned up as follows
Alan Cox:
Squash down the switches into tables, and use the PCI ident field. We
could perhaps take this further and put the platform and port number into
this.
uint32t -> u32
bracketing of case statements
spacing and '!' usage
Check the speed (which is now 0/1/2) is valid and ignore otherwise.
Fix remaining problems/suggestions from Jean's review
Fix items from Ben's review

Hong Liu <hong.liu@intel.com>
The runtime PM code is working on the wrong device (i2c_adapter->dev).
The correct one should be pci_dev->dev. This breaks attached i2c
slave devices with runtime PM enabled. Slave device needs to runtime
resume parent device before runtime resuming itself, but we always get
error since we don't have pm_runtime callback for i2c_adapter->dev.

The driver is not buildable without MFD changes. For now, let's
disable the driver as it breaks build for major platforms (i.e. x86).

We can re-enable it if MFD tree will finally merge into 2.6.37.

bio_clone and bio_alloc allocate from a common bio pool.
If an md device is stacked with other devices that use this pool, or under
something like swap which uses the pool, then the multiple calls on
the pool can cause deadlocks.
So allocate a local bio pool for each md array and use that rather
than the common pool.
This pool is used both for regular IO and metadata updates.
