Dave Miller noted various cases where line disciplines for things like
ppp go poking around in termios themselves in ways that broke with the
new termios code. Rather than have them all learning about termios
internals provide proper methods for this
- tty_mode_ioctl()
This handles all the terminal mode handling for speed/carrier
etc and none of the methods are ldisc dependant so they can be called
by any user
- tty_perform_flush()
This extracts the flush functionality and enables pppd the ppp
layer to share it cleanly.
The existing n_tty_ioctl code is refactored in this patch to provide
the new functions and to call them itself appropriately. This patch

For receive, we now do our own calculation of how much to pull from
the skb (variable length L2TP header) rather than using
skb_transport_offset(). Also, if the skb isn't a data packet, it must
be passed back to UDP with skb->data pointing to the UDP header.

Since patch "fw-sbp2: use an own workqueue (fix system responsiveness)"
increased parallelism between fw-sbp2 and fw-core, it was possible that
fw-sbp2 didn't release the SCSI device when the FireWire device was
disconnected.
This happened if sbp2_update() ran during sbp2_login(), because a bus
reset occurred during sbp2_login(). The sbp2_login() work would [try
to] reschedule itself because it failed due to the bus reset, and it
would _not_ drop its reference on the target. However, sbp2_update()
would schedule sbp2_login() too before sbp2_login() rescheduled itself
and hence sbp2_update() would take an additional reference. And then
we would have one reference too many.
The fix is to _always_ drop the reference when leaving the sbp2_login()
work. If the sbp2_login() work reschedules itself, it takes a
reference, but only if it wasn't already rescheduled by sbp2_update().
Ditto in the sbp2_reconnect() work.
The resulting code is actually simpler than before: We _always_ take
a reference when successfully scheduling work. And we _always_ drop
a reference when leaving a workqueue job. No exceptions.

PCI: Revert "PCI: disable MSI by default on systems with Serverworks HT1000 chips"
Three bugfixes to the leds-gpio driver, plus minor whitespace tweaks:
- Do the INIT_WORK() before registering each LED, so if its trigger
becomes immediately active it can schedule work without oopsing..
- Use normal registration, not platform_driver_probe(), so that
devices appearing "late" (hotplug type) can still be bound.
- Mark the driver remove code as "__devexit", preventing oopses
when the underlying device is removed.
These issues came up when using this driver with some GPIO expanders
living on serial busses, which act unlike "normal" platform devices:
they can appear and vanish along with the serial bus driver.

A reasonably common problem with some devices is that they will
disable MSI generation when the INTX_DISABLE bit is set in the
PCI_COMMAND register.
Quirk this explicitly, guarding the pci_intx() calls in msi.c with
this quirk indication.
The first entries for this quirk are for 5714 and 5780 Tigon3 chips,

https://bugzilla.redhat.com/show_bug.cgi?id=227657
The bnx2 device 5706 complains about MSI not working behind a
ServerWorks HT1000 PCIX bridge. An earlier commit to fix the problem:
e3008dedff4bdc96a5f67224cd3d8d12237082a0:
"PCI: disable MSI by default on systems with Serverworks HT1000 chips"
was not entirely correct, and has been reverted.
MSI does not work on the PCIX bus because the BIOS did not set the
HT_MSI_FLAGS_ENABLE bit in the HyperTransport MSI capability on the
bridge. We use the existing quirk_msi_ht_cap() to detect the problem
and disable MSI in all buses behind it.

The pvrusb2 driver's sysfs implementation had long since implemented a
dummy hotplug function because at the time the kernel would oops
without at least the empty function being present. Today - after
numerous class interface changes in the kernel - this pvrusb2 change
had been dutifully carried forward but an inspection of the kernel
sources shows that it is no longer needed. So remove the dummy
function and its reference. This also solves a recurring backwards
compatibility issue in the pvrusb2 driver as the class interface has
been getting thrashed in the kernel.

The V4L1 spec says that the image size should be with with VIDIOCSWIN before
requesting buffers with VIDIOCGMBUF and capturing into them with
VIDIOCMCAPTURE.
But it seems that many apps don't do this. They set the size using the fields
in the VIDIOCMCAPTURE ioctl. The driver doesn't know what size to capture
until it actually starts to capture. In particular, it doesn't know what size
to capture until it has already mmap the captured buffers. Which is quite
stupid. Why V4L1 has size and format fields for VIDIOCMCAPTURE I have no idea.
Many drivers don't support this, including those using v4l1-compat.
The bttv does, which is probably the only reason such broken software is so
prevalent.
But, the driver doesn't adjust its idea of what size is being captured when it
is set this way. If you try to query the driver's current setting with
v4l2-ctl, it won't be correct.

The bttv driver instists that the depth specified in the call to VIDIOCSPICT
match the pixel format specified in the same call.
vlc doesn't set the depth field, which makes the SPICT ioctl always fail.
The V4L1 standard is not clear on how most operation are supposed to work, and
this is no exception. The depth field would appear to be entirely redundant,
as the pixel format specifies a specific depth. It could be that this field
was only meant for output from the *G*PICT ioctl and should be ignored in
*S*PICT. This is in fact what the v4l1-compat wrapper does.

I have a system here that actively relies upon RTC wake alarms, and it
has been failing (again) for a few days when attempting to use the
/sys/class/rtc/rtc?/wakealarm interface.
The old (fixed by Linus) /proc/ interface still works, but I'd like to
get it using the new one.
This patch fixes rtc-cmos to ignore the two upper bits when reading the
BCD mday (day of month) register from CMOS. Some systems (eg. mine)
seem to have the top bit set to "1" for some reason.
The older /proc/ interface ignores the upper bits, and so we should too.

By setting the request_limit in send_srp_login to 1 we allowed login
requests to be sent to the server adapter. If this was not an initial
login, but was a login after a disconnect with the server, other I/O
requests could attempt to be processed before the login occured. These
I/O requests would fail, sometimes resulting in filesystems getting
marked read-only.
To address this we can set the request_limit to 0 while doing the login
and add an exception where login requests, along with task management
events, are always passed to the server.
There is a case where the request_limit had already reached 0 would result
in all events being sent rather than returning SCSI_MLQUEUE_HOST_BUSY; this
has also been fixed by this patch.

libata EH used to ignore errors not associated with commands when
determining whether speed down is necessary or not. This leads to the
following problems.
* Errors not associated with commands can occur indefinitely without
libata EH taking corrective actions.
* Upstream link errors don't trigger speed down when PMP is attached
to it and commands issued to downstream device trigger errors on the
upstream link.
This patch makes ata_eh_link_autopsy() consider errors not associated
with command for speed down.

Reset failure is a critical error. It results in disabling the link
requiring user intervention to re-enable it. Make reset failure
handling more robust such that libata EH doesn't give up too early.
* Temporary glitches during hardreset may lead to classification
failure when there's no softreset available. Retry instead of
giving up.
* Initial softreset or follow up softreset may fail classification.
Move classification error handling block out of followup softreset
block such that both cases are handled and retry instead of giving
up. Also, on the last try, give ATA class a blind shot.

Commands sent to ATAPI tape drives via the SCSI generic (sg) driver are
limited in the amount of data that they can transfer by the max_sectors
value. The max_sectors value is currently calculated according to the
command set for disk drives, which doesn't apply to tape drives. The
default max_sectors value of 256 limits ATAPI tape drive commands to
128 KB. This patch against 2.6.24-rc1 increases the max_sectors value
for tape drives to 65535, which permits tape drive commands to transfer
just under 32 MB.
Tested with a SuperMicro PDSME motherboard, AHCI, and a Sony SDX-570V
SATA tape drive.
Note that some of the chipset drivers also set their own max_sectors
value, which may override the value set in libata-core. I don't have
any of these chipsets to test, so I didn't go messing with them. Also,
ATAPI devices other than tape drives may benefit from similar changes,
but I have only tape drives and disk drives to test.

The original workaround for the Promise ASIC PRD bug
contained an endianess bug which I failed to detect:
the adjustment of the last PRD entry's length field
applied host arithmetic to little-endian data, which
is incorrect on big-endian machines.
We have the length available in host-endian format, so
do the adjustment on host-endian data and then convert
and store it in the PRD entry's little-endian data field.
Thanks to an anonymous reviewer for detecting this bug.

The Jazz machines have to use the PIT timer for dyntick and highresolution

uses two separate spinlocks in the actual PIT code and the PC speaker
code. So switch to do it the same that x86 currently does PIT locking.
