The includes in the pxa2xx_cm_x2xx PCMCIA driver are rather random;

watchdog: iTCO_wdt.c - problems with newer hardware due to SMI clearing
Redhat Bugzilla: Bug 727875 - TCO_EN bit is disabled by TCO driver
Jiri Slaby:
28d41f53f broke temperature sensors on a ICH10 chipset
The iTCO_wdt driver disables the SMI. This breaks good working of newer hardware.
The disabling of the SMI by the TCO logic dates back from the i810-tco driver
from Nils Faerber (around 28 July 2000). The reason for this was that some BIOSes
install handlers reset or disable the watchdog timer instead of resetting the system.
The trick to fix this was to disable the SMI (by clearing the SMI_TCO_EN bit of the
SMI_EN register) to prevent this from happening.
This however has strange effects on newer hardware. So we are in a situation that
a fix for broken old hardware affects newer hardware.
The correct solution is to make this fix an option (with the new module parameter:
turn_SMI_watchdog_clear_off) so that the default behaviour is the unfixed version.
the next patch will be to move this in the start and stop functions of the driver
and to add a new module parameter for the global_smi_en bit and to get rid of the
vendor_support code.
This fix can have an effect on old (typical ICH & ICH2 chipsets) motherboards that
have a broken BIOS implementation concerning TCO logic. In these case the module
parameter turn_SMI_watchdog_clear_off=1 will need to be added.

sky2: fix regression on Yukon Optima
Changes to support other Optima types, introduced an accidental

The Yukon Optima supports a reverse auto-negotiation feature that
was incorrectly setup, and not needed. The feature could be used to
allow wake-on-lan at higher speeds. But doing it correctly would require
other changes to initialization.

macvlan: receive multicast with local address
When implementing VRRP v2 using macvlan several problems were
discovered. VRRP is weird in that all routers participating
in a redundant group use the same virtual MAC address.
Macvlan is a natural driver to use for this but it doesn't
work. The problem is that packets with a macvlan device's
source address are not received.
The problem is actually a regression that date back almost 2 years now.
The original problems started with:

Commit

TASK_KILLABLE tasks too" updated fake_signal_wake_up() used by freezer
to wake up KILLABLE tasks. Sending unsolicited wakeups to tasks in
killable sleep is dangerous as there are code paths which depend on
tasks not waking up spuriously from KILLABLE sleep.
For example. sys_read() or page can sleep in TASK_KILLABLE assuming
that wait/down/whatever _killable can only fail if we can not return
to the usermode. TASK_TRACED is another obvious example.
The previous patch updated wait_event_freezekillable() such that it
doesn't depend on the spurious wakeup. This patch reverts the
offending commit.
Note that the spurious KILLABLE wakeup had other implicit effects in
KILLABLE sleeps in nfs and cifs and those will need further updates to
regain freezekillable behavior.

USB: Update last_busy time after autosuspend fails
Originally, the runtime PM core would send an idle notification
whenever a suspend attempt failed. The idle callback routine could
then schedule a delayed suspend for some time later.
However this behavior was changed by commit
f71648d73c1650b8b4aceb3856bebbde6daa3b86 (PM / Runtime: Remove idle
notification after failing suspend). No notifications were sent, and
there was no clear mechanism to retry failed suspends.
This caused problems for the usbhid driver, because it fails
autosuspend attempts as long as a key is being held down. A companion
patch changes the PM core's behavior, but we also need to change the

retry the autosuspend in the future when the delay time expires

PM / Sleep: Fix race between CPU hotplug and freezer
The CPU hotplug notifications sent out by the _cpu_up() and _cpu_down()
functions depend on the value of the 'tasks_frozen' argument passed to them
(which indicates whether tasks have been frozen or not).
(Examples for such CPU hotplug notifications: CPU_ONLINE, CPU_ONLINE_FROZEN,
CPU_DEAD, CPU_DEAD_FROZEN).
Thus, it is essential that while the callbacks for those notifications are
running, the state of the system with respect to the tasks being frozen or
not remains unchanged, *throughout that duration*. Hence there is a need for
synchronizing the CPU hotplug code with the freezer subsystem.
Since the freezer is involved only in the Suspend/Hibernate call paths, this
patch hooks the CPU hotplug code to the suspend/hibernate notifiers
PM_[SUSPEND|HIBERNATE]_PREPARE and PM_POST_[SUSPEND|HIBERNATE] to prevent
the race between CPU hotplug and freezer, thus ensuring that CPU hotplug
notifications will always be run with the state of the system really being
what the notifications indicate, _throughout_ their execution time.

The RC error state flush logic in qib_make_rc_req() could return all
of the acked wqes and potentially have emptied the queue. It would
then unconditionally try return a flush completion via
qib_send_complete() for an invalid wqe, or worse a valid one that is
not queued. The panic results when the completion code tries to
maintain an MR reference count for a NULL MR.
This fix modifies logic to only send one completion per
qib_make_rc_req() call and changing the completion status from
IB_WC_SUCCESS to IB_WC_WR_FLUSH_ERR as the completions progress.
The outer loop will call as many times as necessary to flush the queue.
