GCC warns because some tests against 32-bit values never evaluate to true due to how TASK_SIZE is defined. I always wanted to mimick powerpc's definition of TASK_SIZE, which is simply TASK_SIZE_OF(current) and that also fixes the warning. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-10-22sparc: correct section of current_pc()Frederic Weisbecker
Latest mainline gives this section mismatch on sparc: The function current_pc() references the variable __init no_sun4u_here. This is often because current_pc lacks a __init annotation or the annotation of no_sun4u_here is wrong. Since current_pc() is used only in early time, it is correct to put it in .init section.

If apc_no_idle is only used by apc_probe then annotate apc_no_idle with a matching annotation. Since the commit 7e7e2f035663c5ceb029bfb9d91e75099b0a5625, apc_probe() is on __devinit so we have to correct apc_no_idle which is referenced by this function.

2008-10-20container freezer: implement freezer cgroup subsystemMatt Helsley
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.

2008-10-20container freezer: add TIF_FREEZE flag to all architecturesMatt Helsley
This patch series introduces a cgroup subsystem that utilizes the swsusp freezer to freeze a group of tasks. It's immediately useful for batch job management scripts. It should also be useful in the future for implementing container checkpoint/restart. The freezer subsystem in the container filesystem defines a cgroup file named freezer.state. Reading freezer.state will return the current state of the cgroup. Writing "FROZEN" to the state file will freeze all tasks in the cgroup. Subsequently writing "RUNNING" will unfreeze the tasks in the cgroup. * 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 patch: The first step in making the refrigerator() available to all architectures, even for those without power management. The purpose of such a change is to be able to use the refrigerator() in a new control group subsystem which will implement a control group freezer.

2008-10-13serial: allow 8250 to be used on sparcDavid Miller
This requires three changes: 1) Remove !SPARC restriction in Kconfig. 2) Move Sparc specific serial drivers before 8250, so that serial console devices don't change names on us, even if 8250 finds devices. 3) Since the Sparc specific serial drivers try to use the same major/minor device namespace as 8250, some coordination is necessary. Use the sunserial_*() layer routines to allocate minor number space within TTY_MAJOR when CONFIG_SPARC. This has no effect on other platforms.
