if you are lucky (unlucky?) enough to have shared interrupts, the
interrupt handler can be called before the tasklet and lock are ready
for use.

The usb max packet size won't change during the
device's presence. We should store it in a
variable inside rt2x00dev and use that.
This should also fix a division error when the
device is being hot-unplugged while a frame is
being send out.

Plip passes a string "name" that is allocated on stack to
parport_register_device. parport_register_device holds the pointer to
"name" and when the registering function exits, it points nowhere.
On some machine, this bug causes bad names to appear in /proc, such as
/proc/sys/dev/parport/parport0/devices/T^/�X^/�, on others, the plip
proc node is completely missing.
The patch also fixes documentation to note this requirement.

netif_rx is meant to be called from interrupts because it doesn't wake
up ksoftirqd. For calling from outside interrupts, netif_rx_ni exists.
This fixes plip to use netif_rx_ni. It fixes the infamous error "NOHZ:
local_softirq_panding 08" that happens on some machines with NOHZ and
plip --- it is caused by the fact that softirq is pending and ksoftirqd
is sleeping.

None of the drives I have follows what the standard says about
transfer chunk size. Of the four SATA and six PATA ATAPI devices
tested, four ignore transfer chunk size completely and the ones which
honor it don't behave according to the spec when it's odd.
According to the spec, transfer chunk size can be odd if the amount of
data to transfer equals or is smaller than the chunk size and the
device can indicate the same odd number and transfer the whole thing
at one go with a pad byte appended. However, in reality, none of the
drives I have does that. They all indicate and transfer even number
of bytes one byte shorter than the chunk size first; then indicate and
transfer two bytes, which is clearly out of spec.
In addition to unnecessary second PIO data phase, this also creates a
weird problem when combined with SATA controllers which perform PIO
via DMA. Some of these controllers use actualy number of bytes
received to update DMA pointer so chunks which are sized 4n + 2 makes
DMA pointer off by two bytes. This causes data corruption and buffer
overruns.
This patch rounds nbytes up to the nearest even number such that ATAPI
devices don't split data transfer for the last odd byte. This
shouldn't confuse controllers which depend on transfer chunk size as
devices will report the rounded-up number, actually transfer that much
and padding buffer is there to receive them.

sil24 unnecessarily used LIBATA_MAX_PRD and ATAPI sg table was short
by one entry which might cause very obscure problems. This patch
updates sg table sizing such that
* One full page is used for PRB + sg table. On 4k page,
this results in 253 sg's.
* Make ATAPI sg block properly sized.
* Make build fail if command block size doesn't equal PAGE_SIZE.

There are two bugs in disabled port handling.
* test in PORT_PATA0 is reversed
* ->prereset should return -ENOENT for disabled ports not 0
The first bug makes the PATA channel considered disabled but the
second bug saves the day by returning 0. The net result is that cable
is always left at ATA_CBL_UNKNOWN. This results in false 80c
configuration and thus transfer errors.
This patch fixes both bugs.

ICH8 and 9 use two SFF controllers to show 6 SATA ports. The first
controllre hosts the first 4 ports while the second one hosts the last
2. The PCS register of the first controller encompasses the first
four ports or all six ports depending on configuration while PCS of
the second controller controls the last two ports. Using 0xf for the
first controller and 0x3 for the second controller always result in
the correct configuration.

Sebastian Kemper reported that issuing CD/DVD commands under libata is
not fully compatible with ide-scsi. In particular, the
GPCMD_SET_STREAMING was being rejected at the host level in some
instances.
The reason is that libata-scsi insists upon the cmd_len field exactly
matching the SCSI opcode being issued, whereas ide-scsi tolerates
12-byte commands contained within a 16-byte (cmd_len) CDB.
There doesn't seem to be a good reason for us to not be compatible
there, so here is a patch to fix libata-scsi to permit SCSI opcodes so
long as they fit within whatever size CDB is provided.

After an error condition, some ATAPI tape drives set DRQ=1 together
with ERR=1 when asking the host to transfer the CDB of the next packet
command (i.e. request sense). This patch, a revised version of
Alan/Mark's previous patch, adds ATA_HORKAGE_STUCK_ERR to workaround
the problem by ignoring the ERR bit and proceed sending the CDB.

Some controllers fail to send confirmation GPE after address or data write.
Detect this and don't expect such confirmation in future.
This is a generalization of previous workaround
(66c5f4e7367b0085652931b2f3366de29e7ff5ec), which did only read address.

Uncomment '#define DEBUG' at the beginning of file to make EC
really verbose.

In order to be able to write the value "100"
to /proc/acpi/video/.../brightness, we have to allocate 5 bytes:
4 characters will be written (1, 0, 0 plus null byte),
and 1 byte should be buffer for a terminating NULL character.
