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.

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.

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
