6e38a2ba79 Staging: Kconfig for ARCH=arm,8300, cris
The new Kconfig option to build "staging" drivers (code in
drivers/staging/) is seen in all except three architectures (arm, h8300,
cris), because in these cases arch/$ARCH/Kconfig does NOT source
drivers/Kconfig.

This patch adds the source "drivers/staging/Kconfig" to
arch/$ARCH/Kconfig for these three exceptional cases.

72880ad866 [ARM] KS8695: Fixup the KS8695 GPIO to be GPIOLIB
This patch is as small a change as possible to the KS8695 GPIO layer
to use GPIOLIB to allow the generic GPIO expanders and the like to
be compiled.

As a side-effect, we also remove __init_or_module from several
functions which could be called by drivers such as i2c-gpio which
could plausibly be compiled into a non-modular kernel.

07c4cc1cda ftrace: disable dynamic ftrace for all archs that use daemon
The ftrace daemon is complex and can cause nasty races if something goes
wrong. Since it affects all of the kernel, this patch disables dynamic
ftrace from any arch that depends on the daemon. Until the archs are
ported over to the new MCOUNT_RECORD method, I am disabling dynamic
ftrace from them.

Note: I am leaving in the arch/<arch>/kernel/ftrace.c code alone since
that can be used when the arch is ported to MCOUNT_RECORD. To port
the arch to MCOUNT_RECORD, the scripts/recordmcount.pl needs to be
updated. I will make that easier to do for 2.6.29. For 28, we will keep
the archs disabled.

The MSM architecture covers a wider family of chips than just the MSM7X00A.
Move to a more generic name, in perparation for supporting the specific
SoC variants as sub-architectures (ARCH_MSM7X01A, ARCH_MSM722X, etc).  This
gives us ARCH_MSM for the (many) common peripherals.

This also removes the unused/obsolete config item MSM7X00A_IDLE.

dc52ddc0e6 container freezer: implement freezer cgroup subsystem
This patch implements a new freezer subsystem in the control groups
framework.  It provides a way to stop and resume execution of all tasks in
a cgroup by writing in the cgroup filesystem.

The freezer subsystem in the container filesystem defines a file named
freezer.state.  Writing "FROZEN" to the state file will freeze all tasks
in the cgroup.  Subsequently writing "RUNNING" will unfreeze the tasks in
the cgroup.  Reading will return the current state.

* Examples of usage :

   # mkdir /containers/freezer
   # mount -t cgroup -ofreezer freezer  /containers
   # mkdir /containers/0
   # echo $some_pid > /containers/0/tasks

to get status of the freezer subsystem :

   # cat /containers/0/freezer.state
   RUNNING

to freeze all tasks in the container :

   # echo FROZEN > /containers/0/freezer.state
   # cat /containers/0/freezer.state
   FREEZING
   # cat /containers/0/freezer.state
   FROZEN

to unfreeze all tasks in the container :

   # echo RUNNING > /containers/0/freezer.state
   # cat /containers/0/freezer.state
   RUNNING

This is the basic mechanism which should do the right thing for user space
task in a simple scenario.

It's important to note that freezing can be incomplete.  In that case we
return EBUSY.  This means that some tasks in the cgroup are busy doing
something that prevents us from completely freezing the cgroup at this
time.  After EBUSY, the cgroup will remain partially frozen -- reflected
by freezer.state reporting "FREEZING" when read.  The state will remain
"FREEZING" until one of these things happens:

	1) Userspace cancels the freezing operation by writing "RUNNING" to
		the freezer.state file
	2) Userspace retries the freezing operation by writing "FROZEN" to
		the freezer.state file (writing "FREEZING" is not legal
		and returns EIO)
	3) The tasks that blocked the cgroup from entering the "FROZEN"
		state disappear from the cgroup's set of tasks.

3bca103a1e [ARM] 5295/1: make ZONE_DMA optional
Most ARM machines don't need a special "DMA" memory zone, and
when configured out, the kernel becomes a bit smaller:

|   text    data     bss     dec     hex filename
|3826182  102384  111700 4040266  3da64a vmlinux
|3823593  101616  111700 4036909  3d992d vmlinux.nodmazone

This is because the system now has only one zone total which effect is
to optimize away many conditionals in page allocation paths.

So let's configure this zone only on machines that need split zones.
