d6532232cd sky2: fix VLAN receive processing (resend)
The length check for truncated frames was not correctly handling
the case where VLAN acceleration had already read the tag.
Also, the Yukon EX has some features that use high bit of status
as security tag.

be7963b7e7 ieee1394: ohci1394: fix initialization if built non-modular
Initialization of ohci1394 was broken according to one reporter if the
driver was statically linked, i.e. not built as loadable module.  Dmesg:

  PCI: Device 0000:02:07.0 not available because of resource collisions
  ohci1394: Failed to enable OHCI hardware.

This was reported for a Toshiba Satellite 5100-503.  The cause is commit
8df4083c52 in Linux 2.6.19-rc1 which only
served purposes of early remote debugging via FireWire.  This
functionality is better provided by the currently out-of-tree driver
ohci1394_earlyinit.  Reversal of the commit was OK'd by Andi Kleen.

f3d5e3a415 [PPP] L2TP: Fix skb handling in pppol2tp_xmit
This patch makes pppol2tp_xmit call skb_cow_head so that we don't modify
cloned skb data.  It also gets rid of skb2 we only need to preserve the
original skb for congestion notification, which is only applicable for
ppp_async and ppp_sync.

The other semantic change made here is the removal of socket accounting
for data tranmitted out of pppol2tp_xmit.  The original code leaked any
existing socket skb accounting.  We could fix this by dropping the
original skb owner.  However, this is undesirable as the packet has not
physically left the host yet.

In fact, all other tunnels in the kernel do not account skb's passing
through to their own socket.  In partciular, ESP over UDP does not do
so and it is the closest tunnel type to PPPoL2TP.  So this patch simply
removes the socket accounting in pppol2tp_xmit.  The accounting still
applies to control packets of course.

I've also added a reminder that the outgoing checksum here doesn't work.
I suppose existing deployments don't actually enable checksums.

d78ae2dcc2 r8169: workaround against ignored TxPoll writes (8168)
The 8168 ignores the requests to fetch the Tx descriptors when
the relevant TxPoll bit is already set. It easily kills the
performances of the 8168. David Gundersen has noticed that it
is enough to wait for the completion of the DMA transfer (NPQ
bit is cleared) before writing the TxPoll register again.

The extra IO traffic added by the proposed workaround could be
minimalized but it is not a high-priority task.

4191ba26da mspec: handle shrinking virtual memory areas
The shrinking of a virtual memory area that is mmap(2)'d to a memory
special file (device drivers/char/mspec.c) can cause a panic.

If the mapped size of the vma (vm_area_struct) is very large, mspec allocates
a large vma_data structure with vmalloc(). But such a vma can be shrunk by
an munmap(2).  The current driver uses the current size of each vma to
deduce whether its vma_data structure was allocated by kmalloc() or vmalloc().
So if the vma was shrunk it appears to have been allocated by kmalloc(),
and mspec attempts to free it with kfree().  This results in a panic.

This patch avoids the panic (by preserving the type of the allocation) and
also makes mspec work correctly as the vma is split into pieces by the
munmap(2)'s.

All vma's derived from such a split vma share the same vma_data structure that
represents all the pages mapped into this set of vma's.  The mpec driver
must be made capable of using the right portion of the structure for each
member vma.  In other words, it must index into the array of page addresses
using the portion of the array that represents the current vma. This is
enabled by storing the vma group's vm_start in the vma_data structure.

The shared vma_data's are not protected by mm->mmap_sem in the fork() case
so the reference count is left as atomic_t.

2e3e31c057 rtc-ds1742.c should use resource_size_t for base address
Currently the rtc driver, rtc-ds1742.c uses an unsigned long to store the
base mmio address of the NVRAM/RTC.  This breaks on systems like PowerPC
440, which is a 32-bit core with 36-bit physical addresses: IO on the
system, including the RTC, is typically above the 4GB point, and cannot fit
into an unsigned long.

This patch fixes the problem by replacing the unsigned long with a
resource_size_t.  Tested on Ebony (PPC440) (with additional patches to
instantiate the ds1742 platform device appropriately).

a21101c46c ACPI: video: _DOS=0 by default to prevent hotkey hang
In the past, the Linux/ACPI video driver invoked _DOS
(Display Output Switch) with the parameter 1
to tell the BIOS to switch the video output display for us.

But this conflicts with Linux native graphics drivers,
and can cause all sorts of issues, including hanging the system.

http://bugzilla.kernel.org/show_bug.cgi?id=6001

Here we change the Linux default to evaluate _DOS=0,
which tells the BIOS to simply send us a hotkey event
and not touch the graphics hardware.

The acpi video driver sends the display switch hotkey
event up through the intput layer, and X can interpret
that and use its native graphics driver to switch the display.

For the case where Linux has no native graphics driver running,
or the graphics driver doesn't know how to switch video and
the BIOS (safely) does, the previous behaviour can be restored with:

# echo 1 > /proc/acpi/video/*/DOS

ff80f1370f ACPI: thinkpad-acpi: revert new 2.6.23 CONFIG_THINKPAD_ACPI_INPUT_ENABLED option
Revert new 2.6.23 CONFIG_THINKPAD_ACPI_INPUT_ENABLED Kconfig option because
it would create a legacy we don't want to support.

CONFIG_THINKPAD_ACPI_INPUT_ENABLED was added to try to fix an issue that is
now moot with the addition of the netlink ACPI event report interface to
the ACPI core.

Now that ACPI core can send events over netlink, we can use a different
strategy to keep backwards compatibility with older userspace, without the
need for the CONFIG_THINKPAD_ACPI_INPUT_ENABLED games.  And it arrived
before CONFIG_THINKPAD_ACPI_INPUT_ENABLED made it to a stable mainline
kernel, even, which is Good.

This patch is in sync with some changes to thinkpad-acpi backports, that
will keep things sane for userspace across different combinations of kernel
versions, thinkpad-acpi backports (or the lack thereof), and userspace
capabilities:

Unless a module parameter is used, thinkpad-acpi will now behave in such a
way that it will work well (by default) with userspace that still uses only
the old ACPI procfs event interface and doesn't care for thinkpad-acpi
input devices.

It will also always work well with userspace that has been updated to use
both the thinkpad-acpi input devices, and ACPI core netlink event
interface, regardless of any module parameter.

The module parameter was added to allow thinkpad-acpi to work with
userspace that has been partially updated to use thinkpad-acpi input
devices, but not the new ACPI core netlink event interface.  To use this
mode of hot key reporting, one has to specify the hotkey_report_mode=2
module parameter.

The thinkpad-acpi driver exports the value of hotkey_report_mode through
sysfs, as well.  thinkpad-acpi backports to older kernels, that do not
support the new ACPI core netlink interface, have code to allow userspace
to switch hotkey_report_mode at runtime through sysfs.  This capability
will not be provided in mainline thinkpad-acpi as it is not needed there.

In fact, it currently allocates a new skb so that it can return 0 in
case of error without freeing the original skb.  This is totally wrong
because returning zero is meant to indicate congestion whereupon pppoe
is supposed to wake up the upper layer once the congestion subsides.

This makes sense for ppp_async and ppp_sync but is out-of-place for
pppoe.  This patch makes it always return 1 and free the skb.

3f7086978f [PATCH] bcm43xx: Fix cancellation of work queue crashes
A crash upon booting that is caused by bcm43xx has been reported [1] and
found to be due to a work queue being reinitialized while work on that
queue is still pending. This fix modifies the shutdown of work queues and
prevents periodic work from being requeued during shutdown. With this patch,
no more crashes on reboot were observed by the original reporter. I do not
get that particular failure on my system; however, when running a large
number of ifdown/ifup sequences, my system would kernel panic with the
'caps lock' light blinking at roughly a 1 Hz rate. In addition, there were
infrequent failures in the firmware that resulted in 'IRQ READY TIMEOUT'
errors. With this patch, no more of the first type of failure occur, and
incidence of the second type is greatly reduced.

Right now the composite sound input doesn't work on AverTV 307 because of

This bug also hid a second bug: when a capture is stopped a last entry is

returned to the caller as a P frame.

a041fe2e8d spidernet: fix interrupt reason recognition
This patch solves a problem that the spidernet driver sometimes fails
to handle IRQ.

The problem happens because,
- In Cell architecture, interrupts may arrive at an interrupt
  controller, even if they are masked by the setting on registers of
  devices. It happens when interrupt packets are sent just before
  the interrupts are masked.
- spidernet interrupt handler compares interrupt reasons with
  interrupt masks, so when such interrupts occurs, spidernet interrupt
  handler returns IRQ_NONE.
- When all of interrupt handler return IRQ_NONE, linux kernel disables
  the IRQ and it no longer delivers interrupts to the interrupt handlers.

spidernet doesn't work after above sequence, because it can't receive
interrupts.

This patch changes spidernet interrupt handler that it compares
interrupt reason with SPIDER_NET_INTX_MASK_VALUE.

memcpy -> _mmx_memcpy -> kernel_fpu_begin -> clts -> paravirt_ops.clts

But we haven't set paravirt_ops.clts yet, so we do the native version
and crash.  The simplest solution is to use __memcpy.

f629307c85 tty: termios locking functions break with new termios type
I ran into a few problems.

n_tty_ioctl() for instance:

drivers/char/tty_ioctl.c:799: error: $,1rxstruct termios$,1ry has no
member named $,1rxc_ispeed$,1ry

This is calling the copy interface that is supposed to be using
a termios2 when the new interfaces are defined, however:

	case TIOCGLCKTRMIOS:
		if (kernel_termios_to_user_termios((struct termios __user *)arg, real_tty->termios_locked))
			return -EFAULT;
		return 0;

This is going to write over the end of the userspace
structure by a few bytes, and wasn't caught by you yet
because the i386 implementation is simply copy_to_user()
which does zero type checking.

a2e0855182 md: fix some bugs with growing raid5/raid6 arrays.
The recent changed to raid5 to allow offload of parity calculation etc
introduced some bugs in the code for growing (i.e.  adding a disk to) raid5
and raid6.  This fixes them

65e213cdb2 spi_mpc83xx: hang fix
When the spi_mpc83xx driver receives a tx_buf pointer which is NULL, it
only writes one zero filled word to the transmit register.  If the driver
expects to receive more than one word it will wait forever for a second
receive interrupt.  With this patch the controller will shift out zeroes
until all words have been received.

2808b0a96a hpt366: UltraDMA filter for SATA cards (take 2)
The Marvell bridge chips used on HighPoint SATA cards do not seem to support
the UltraDMA modes 1, 2, and 3 as well as any MWDMA modes, so the driver needs
to account for this in the udma_filter() method.  In order to achieve that, do
the following changes:

- install the method for all chips, not only HPT36x/370 and improve the code
  formatting by killing the extra tabs while at it;

- add to the end of the 'switch' statement in the method cases for HPT372[AN]
  and HPT374 chips upon which the known SATA cards are based;

- use hwif->ultra_mask as a default mask for the ide_dma_filter() method to
  behave correctly;

- move the HPT370[A] cases below the HPT36x case for consistency.

While at it, replace the explicit UltraDMA mode masks with ATA_UDMA* constants
all over the driver...

The IDE core never marked the PCI IDE devices as being in use after succesfull

so was susceptible to issues caused by unsolicited PCI hotplug device removal.
So, add pci_dev_get() call to ide_scan_pcidev() and convert this function to

c4766560e4 USB Mass Storage: limit "Rockchip ROCK MP3" device (071b:3203) max I/O to 64 sectors per command
The MP3/MP4/AVI player "Rockchip ROCK MP3" is seen as a USB disk, but fails
if more than 128 sectors (64kB) are sent or requested in a single read or write
command, and disconnects from the USB bus.

Typical kernel log showing the problem is:

usb 3-1: reset high speed USB device using ehci_hcd and address 6
usb 3-1: reset high speed USB device using ehci_hcd and address 6
sd 14:0:0:0: [sdb] Result: hostbyte=0x07 driverbyte=0x00
end_request: I/O error, dev sdb, sector 32
sd 14:0:0:0: [sdb] Result: hostbyte=0x07 driverbyte=0x00
end_request: I/O error, dev sdb, sector 32
usb 3-1: USB disconnect, address 6

This patch works around the device limitation by adding "Rockchip ROCK MP3"
to unusual USB devices list and limiting data transfers to 64 sectors (32kB)
per command.
Tested on 2.6.23-rc5 (amd64).

On MIPS I have the call chains pci_scan_child_bus -> pcibios_fixup_bus ->
pci_read_bridge_bases.  pci_scan_child_bus can't be __devinit because it
it is an exported symbol, thus pcibios_fixup_bus and pci_read_bridge_bases
can't be either.

2fbe43f6f6 [TG3]: Workaround MSI bug on 5714/5780.
A hardware bug was revealed after a recent PCI MSI patch was made to
always disable legacy INTX when enabling MSI.  The 5714/5780 chips
will not generate MSI when INTX is disabled, causing MSI failure
messages to be reported, and another patch was made to workaround the
problem by disabling MSI on ServerWorks HT1000 bridge chips commonly
found with the 5714.

We workaround this chip bug by enabling INTX after we enable MSI and
after we resume from suspend.

Update version to 3.81.

This problem was discovered by David Miller.

bce7d5e0e1 pata_it821x: fix lost interrupt with atapi devices
Fix "lost" interrupt problem when using dma with CD/DVD drives in some
configurations.  This problem can make installing linux from media
impossible for distro's that have switched to libata-only configurations.

The simple fix is to eliminate the use of dma for reading drive status, etc,
by checking the number of bytes to transferred.

This change will only affect the behavior of atapi devices, not disks.
There is more info at http://bugzilla.redhat.com/show_bug.cgi?id=242229

939bc4943d i2c-algo-bit: Read block data bugfix
This fixes a bug in the way i2c-algo-bit handles I2C_M_RECV_LEN,
used to implement i2c_smbus_read_block_data().  Previously, in the
absence of PEC (rarely used!) it would NAK the "length" byte:

	S addr Rd [A] [length] NA

That prevents the subsequent data bytes from being read:

	S addr Rd [A] [length] { A [data] }* NA

The primary fix just reorders two code blocks, so the length used
in the "should I NAK now?" check incorporates the data which it
just read from the slave device.

However, that move also highlighted other fault handling glitches.
This fixes those by abstracting the RX path ack/nak logic, so it
can be used in more than one location.  Also, a few CodingStyle
issues were also resolved.

3b2b64fd31 Do not use the ia64 clocksource on non-ia64 architectures
The HPET clocksource in drivers/char/hpet.c was written as generic code
for ia64, but it is not yet ready to replace the native HPET clocksource
implementations that the i386/x86-64 architectures use.

On x86[-64], trying to register this clocksource results in potentially
multiple hpet-based clocksources being registered, and if the ia64 one
is chosen on x86_64 some users have experienced hangs.

Eventually all three architectures may end up using the same code, but
that is not the case right now.
