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.

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.

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.

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

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.

The function __pppoe_xmit modifies the skb data and therefore it needs
to copy and skb data if it's cloned.
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.

Right now the composite sound input doesn't work on AverTV 307 because of
the wrong mux setup. The composite sound is routed via an external
4channel multiplexer controlled by GPIO, while the code assumes an internal
multiplexer instead.
Presumably this was a copy/paste error, and noone have ever tested the
functionality.
With the attached patch it works properly, which gives me an ability to
finally watch the cable TV under linux.

Due to a documentation bug (the type mask is 3 bits long, not 2) the wrong
frame types were filled in: the B and P frame types were swapped.
This bug also hid a second bug: when a capture is stopped a last entry is
written into the pgm index buffer with internal type 0, denoting the end
of the program. This entry wasn't ignored, instead it was accidentally
returned to the caller as a P frame.

This fixes a problem introduced with commit
b5f2f4d1a6
The commit added a wrong chip definition to radeonfb which causes
a blank console on my Laptop if radeonfb is loaded.
The patch
- renames PCI_CHIP_RS485_5975 to PCI_CHIP_RS482_5975
- corrects the chip family (RS480 instead of R300) for 0x5975
- ensures that PCI IDs are in ascending order in ati_ids.h

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.

Introduces a module parameter to decide whether the physical
port link state is propagated to the network stack or not.
It makes sense not to take the physical port state into account
on machines with more logical partitions that communicate
with each other. This is always possible no matter what the physical
port state is. Thus eHEA can be considered as a switch there.

One of the very first things lguest_init() does is a memcpy. On
Athlon/Duron/K7 or CyrixIII/VIA-C3 or Geode GX/LX, this tries to use
MMX.
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.

Intel framebuffer mis-calculated pixel clocks.
The pixel clock (and thus both H and V sync) will be slower than requested, so
if you set the minimum allowed the display may not sync. In case of really
old CRT display it could theoretically damage it.
I'm using it with PAL TV (using RGB input - SCART connector) and the bug
prevented it from working at all (TV requirements are more strict and made the
bug visible).

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.
