c9308b06c0 [PATCH] ieee80211: Move IV/ICV stripping into ieee80211_rx
This patch adds a host_strip_iv_icv flag to ieee80211 which indicates that
ieee80211_rx should strip the IV/ICV/other security features from the payload.
This saves on some memmove() calls in the driver and seems like something that
belongs in the stack as it can be used by bcm43xx, ipw2200, and zd1211rw

I will submit the ipw2200 patch separately as it needs testing.

This patch also adds some sensible variable reuse (idx vs keyidx) in
ieee80211_rx

6c3561b0c1 [PATCH] beginning of 8390 fixes - generic and arm/etherh
etherh and a handful of other odd drivers use different macros when building
8390.c.  Since we generate a single 8390.o and then link with it, in any
config with both oddball and normal 8390-based driver we will end up with
breakage in at least one of them.  Solution: take most of 8390.c into
lib8390.c and have 8390.c, etherh.c and the rest of oddballs #include it.
Helper macros are taken from 8390.h to whoever includes lib8390.c.  That
way odd drivers get separate instances of compiled 8390 stuff and stop
stepping on each other's toes.  8390.h gets cleaned up - we don't have
the cascade of ifdefs in there and are left with the stuff that can be
used by any 8390-based driver.  Current problems are exactly because of
that cascade - we attempt to choose the set of helpers by looking at config
and that, of course, doesn't work well when we have several sets needed
by various drivers in our config.

a189317fa0 [PATCH] forcedeth: power management support
Tobias Diedrich <ranma@tdiedrich.de> sayeth:

Vanilla forcedeth doesn't seem to support suspend and an ifdown/up-cycle is
needed to get it working again after suspend.  Francois Romieu's "Awfully
experimental" patch is working just fine for me (with message signalled
interrupts disabled) and has survived quite a few suspend/resume cycles.

So I'd very much like to see (at least partial, with msi disabled)
suspend support for forcedeth in mainline.

3c3070d713 [PATCH] 2.6.18: sb1250-mac: Phylib IRQ handling fixes
This patch fixes a couple of problems discovered with interrupt handling
in the phylib core, namely:

1. The driver uses timer and workqueue calls, but does not include
   <linux/timer.h> nor <linux/workqueue.h>.

2. The driver uses schedule_work() for handling interrupts, but does not
   make sure any pending work scheduled thus has been completed before
   driver's structures get freed from memory.  This is especially
   important as interrupts may keep arriving if the line is shared with
   another PHY.

   The solution is to ignore phy_interrupt() calls if the reported device
   has already been halted and calling flush_scheduled_work() from
   phy_stop_interrupts() (but guarded with current_is_keventd() in case
   the function has been called through keventd from the MAC device's
   close call to avoid a deadlock on the netlink lock).

c67334fbdf Driver core: platform_driver_probe(), can save codespace
This defines a new platform_driver_probe() method allowing the driver's
probe() method, and its support code+data, to safely live in __init
sections for typical system configurations.

Many system-on-chip processors could benefit from this API, to the tune
of recovering hundreds to thousands of bytes per driver.  That's memory
which is currently wasted holding code which can never be called after
system startup, yet can not be removed.   It can't be removed because of
the linkage requirement that pointers to init section code (like, ideally,
probe support) must not live in other sections (like driver method tables)
after those pointers would be invalid.

06a4bcae1f cpu topology: consider sysfs_create_group return value
Take return value of sysfs_create_group() into account.  That function got
called in case of CPU_ONLINE notification.  Since callbacks are not allowed
to fail on CPU_ONLINE notification do the sysfs group creation on
CPU_UP_PREPARE notification.

Also remember if creation succeeded in a bitmask.  So it's possible to know
whether it's legal to call sysfs_remove_group or not.

In addition some other minor stuff:

- since CPU_UP_PREPARE might fail add CPU_UP_CANCELED handling as well.
- use hotcpu_notifier instead of register_hotcpu_notifier.
- #ifdef code that isn't needed in the !CONFIG_HOTPLUG_CPU case.

1901fb2604 Driver core: fix "driver" symlink timing
Create the "driver" link before the child device may be created by
the probing logic. This makes it possible for userspace (udev), to
determine the driver property of the parent device, at the time the
child device is created.

116af37820 Driver core: add notification of bus events
I finally did as you suggested and added the notifier to the struct
bus_type itself. There are still problems to be expected is something
attaches to a bus type where the code can hook in different struct
device sub-classes (which is imho a big bogosity but I won't even try to
argue that case now) but it will solve nicely a number of issues I've
had so far.

That also means that clients interested in registering for such
notifications have to do it before devices are added and after bus types
are registered. Fortunately, most bus types that matter for the various
usage scenarios I have in mind are registerd at postcore_initcall time,
which means I have a really nice spot at arch_initcall time to add my
notifiers.

There are 4 notifications provided. Device being added (before hooked to
the bus) and removed (failure of previous case or after being unhooked
from the bus), along with driver being bound to a device and about to be
unbound.

The usage I have for these are:

 - The 2 first ones are used to maintain a struct device_ext that is
hooked to struct device.firmware_data. This structure contains for now a
pointer to the Open Firmware node related to the device (if any), the
NUMA node ID (for quick access to it) and the DMA operations pointers &
iommu table instance for DMA to/from this device. For bus types I own
(like IBM VIO or EBUS), I just maintain that structure directly from the
bus code when creating the devices. But for bus types managed by generic
code like PCI or platform (actually, of_platform which is a variation of
platform linked to Open Firmware device-tree), I need this notifier.

 - The other two ones have a completely different usage scenario. I have
cases where multiple devices and their drivers depend on each other. For
example, the IBM EMAC network driver needs to attach to a MAL DMA engine
which is a separate device, and a PHY interface which is also a separate
device. They are all of_platform_device's (well, about to be with my
upcoming patches) but there is no say in what precise order the core
will "probe" them and instanciate the various modules. The solution I
found for that is to have the drivers for emac to use multithread_probe,
and wait for a driver to be bound to the target MAL and PHY control
devices (the device-tree contains reference to the MAL and PHY interface
nodes, which I can then match to of_platform_devices). Right now, I've
been polling, but with that notifier, I can more cleanly wait (with a
timeout of course).
