As promised in feature-removal-schedule.txt it is time to
remove the nfsctl system call.
Userspace has perferred to not use this call throughout 2.6 and it has been
excluded in the default configuration since 2.6.36 (9 months ago).
So this patch removes all the code that was being compiled out.
There are still references to sys_nfsctl in various arch systemcall tables
and related code. These should be cleaned out too, probably in the next
merge window.

DESTROY_CLIENTID MAY be preceded with a SEQUENCE operation as long as
the client ID derived from the session ID of SEQUENCE is not the same
as the client ID to be destroyed. If the client IDs are the same,
then the server MUST return NFS4ERR_CLIENTID_BUSY.
(that's not implemented yet)
If DESTROY_CLIENTID is not prefixed by SEQUENCE, it MUST be the only
operation in the COMPOUND request (otherwise, the server MUST return
NFS4ERR_NOT_ONLY_OP).
This fixes the error return; before, we returned
NFS4ERR_OP_NOT_IN_SESSION; after this patch, we return NFS4ERR_NOTSUPP.

A system or a device may need to control suspend/wakeup events. It may
want to wakeup the system after a predefined amount of time or at a
predefined event decided while entering suspend for polling or delayed
work. Then, it may want to enter suspend again if its predefined wakeup
condition is the only wakeup reason and there is no outstanding events;
thus, it does not wakeup the userspace unnecessary or unnecessary
devices and keeps suspended as long as possible (saving the power).
Enabling a system to wakeup after a specified time can be easily
achieved by using RTC. However, to enter suspend again immediately
without invoking userland and unrelated devices, we need additional
features in the suspend framework.
Such need comes from:
1. Monitoring a critical device status without interrupts that can
wakeup the system. (in-suspend polling)
An example is ambient temperature monitoring that needs to shut down
the system or a specific device function if it is too hot or cold. The
temperature of a specific device may be needed to be monitored as well;
e.g., a charger monitors battery temperature in order to stop charging
if overheated.
2. Execute critical "delayed work" at suspend.
A driver or a system/board may have a delayed work (or any similar
things) that it wants to execute at the requested time.
For example, some chargers want to check the battery voltage some
time (e.g., 30 seconds) after the battery is fully charged and the
charger has stopped. Then, the charger restarts charging if the voltage
has dropped more than a threshold, which is smaller than "restart-charger"
voltage, which is a threshold to restart charging regardless of the
time passed.
This patch allows to add "suspend_again" callback at struct
platform_suspend_ops and let the "suspend_again" callback return true if
the system is required to enter suspend again after the current instance
of wakeup. Device-wise suspend_again implemented at dev_pm_ops or
syscore is not done because: a) suspend_again feature is usually under
platform-wise decision and controls the behavior of the whole platform
and b) There are very limited devices related to the usage cases of
suspend_again; chargers and temperature sensors are mentioned so far.
With suspend_again callback registered at struct platform_suspend_ops
suspend_ops in kernel/power/suspend.c with suspend_set_ops by the
platform, the suspend framework tries to enter suspend again by
looping suspend_enter() if suspend_again has returned true and there has
been no errors in the suspending sequence or pending wakeups (by
pm_wakeup_pending).
Tested at Exynos4-NURI.

Instead of having firmware command functions return an error and also
a status, leading to code like:
err = mthca_FW_COMMAND(..., &status);
if (err)
goto out;
if (status) {
err = -E...;
goto out;
}
all over the place, just handle the FW status inside the FW command
handling code (the way mlx4 does it), so we can simply write:
err = mthca_FW_COMMAND(...);
if (err)
goto out;
In addition to simplifying the source code, this also saves a healthy
chunk of text:

Support adding probes on offline kernel modules. This enables
perf-probe to trace kernel-module init functions via perf-probe.
If user gives the path of module with -m option, perf-probe
expects the module is offline.
This feature works with --add, --funcs, and --vars.
E.g)
# perf probe -m /lib/modules/`uname -r`/kernel/fs/btrfs/btrfs.ko \
-a "extent_io_init:5 extent_state_cache"
Add new events:
probe:extent_io_init (on extent_io_init:5 with extent_state_cache)
probe:extent_io_init_1 (on extent_io_init:5 with extent_state_cache)
You can now use it on all perf tools, such as:
perf record -e probe:extent_io_init_1 -aR sleep 1

Add i2c bindings for the mcp230xx devices. This is quite a lot simpler
than the spi one as there's no funky sub addressing done (one struct
i2c_client per struct gpio_chip).
The mcp23s08_platform_data structure is reused for i2c, even though
only a single mcp23s08_chip_info structure is needed.
To use, simply fill out a platform_data structure and pass it in
i2c_board_info, E.G.:
static const struct mcp23s08_platform_data mcp23017_data = {
.chip[0] = {
.pullups = 0x00ff,
},
.base = 240,
};
static struct i2c_board_info __initdata i2c_devs[] = {
{ I2C_BOARD_INFO("mcp23017", 0x20),
.platform_data = &smartview_mcp23017_data, },

To support probing module init functions, kprobe-tracer allows
user to define a probe on non-existed function when it is given
with a module name. This also enables user to set a probe on
a function on a specific module, even if a same name (but different)
function is locally defined in another module.
The module name must be in the front of function name and separated
by a ':'. e.g. btrfs:btrfs_init_sysfs

When suspending with all netdevs down, the device
is stopped but we still call a number of driver
callbacks that the driver might not expect. The
same happens during resume, we might call a few
callbacks without starting the driver. Fix this
by checking open_count around more things and
exiting quickly if it is 0.
Also, while at this I noticed that the coverage

ieee80211_iter_keys() currently returns keys in
the backward order they were installed in, which
is a bit confusing. Add them to the tail of the
key list to make sure iterations go in the same
order that keys were originally installed in.

When the driver wants to pre-program the TKIP
RX phase 1 key, it needs to be able to obtain
it for the peer's TA. Add API to allow it to
generate it.
The generation uses a dummy on-stack context
since it doesn't know the RX queue.

For unicast the hardware sometimes reports MIC errors even though the
frame that it received actually contains a valid MIC - on some chips this
can happen frequently enough to trigger TKIP countermeasures.
Fix this issue by not reporting MIC errors for unicast frames with a
valid key, letting mac80211 validate the MIC instead.
Additionally, strip the MIC for all frames that the hardware considers
valid to avoid wasting CPU cycles re-validating it.

As ieee80211_tx_info->control.sta may be NULL during ->tx call, avoiding sta
dereference in such scenario with the following patch.

Some chips may support different lengths of user-supplied IEs with a
single scheduled scan command than with a single normal scan command.
To support this, this patch creates a separate hardware description
element that describes the maximum size of user-supplied information
element data supported in scheduled scans.

Some chips can scan more SSIDs with a single scheduled scan command

Since we now have the necessary API in place to support
GTK rekeying, applications will need to know whether it
is supported by a device. Add a pseudo-trigger that is
used only to advertise that capability. Also, add some
new triggers that match what iwlagn devices can do.

Instead of creating our own kthread (dlm_astd) to deliver
callbacks for all lockspaces, use a per-lockspace workqueue
to deliver the callbacks. This eliminates complications and
slowdowns from many lockspaces sharing the same thread.

There are a least three different species we need to deal with and right
now it seems the only way to sort them out is via DMI. Encapsulate the
entire pile somewhere private and out of the way.
Hopefully a saner method will emerge later.
