2008-10-23ftrace: disable dynamic ftrace for all archs that use daemonSteven Rostedt
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.

2008-10-20ftrace: rename FTRACE to FUNCTION_TRACERSteven Rostedt
Due to confusion between the ftrace infrastructure and the gcc profiling tracer "ftrace", this patch renames the config options from FTRACE to FUNCTION_TRACER. The other two names that are offspring from FTRACE DYNAMIC_FTRACE and FTRACE_MCOUNT_RECORD will stay the same. This patch was generated mostly by script, and partially by hand.

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.

2008-07-17sparc64: Remove 4MB and 512K base page size options.David S. Miller
Adrian Bunk reported that enabling 4MB page size breaks the build. The problem is that MAX_ORDER combined with the page shift exceeds the SECTION_SIZE_BITS we use in asm-sparc64/sparsemem.h There are several ways I suppose we could work around this. For one we could define a CONFIG_FORCE_MAX_ZONEORDER to decrease MAX_ORDER in these higher page size cases. But I also know that these page size cases are broken wrt. TLB miss handling especially on pre-hypervisor systems, and there isn't an easy way to fix that. These options were meant to be fun experimental hacks anyways, and only 8K and 64K make any sense to support. So remove 512K and 4M base page size support. Of course, we still support these page sizes for huge pages. Signed-off-by: David S. Miller <davem@davemloft.net>

Linus: On the per-architecture side, I do think it would be better to *not* have internal architecture knowledge in a generic file, and as such a line like depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32 really shouldn't exist in a file like kernel/Kconfig.instrumentation. It would be much better to do depends on ARCH_SUPPORTS_KPROBES in that generic file, and then architectures that do support it would just have a bool ARCH_SUPPORTS_KPROBES default y in *their* architecture files. That would seem to be much more logical, and is readable both for arch maintainers *and* for people who have no clue - and don't care - about which architecture is supposed to support which interface... Changelog: Actually, I know I gave this as the magic incantation, but now that I see it, I realize that I should have told you to just use config KPROBES_SUPPORT def_bool y instead, which is a bit denser.

2008-01-30spinlock: lockbreak cleanupNick Piggin
The break_lock data structure and code for spinlocks is quite nasty. Not only does it double the size of a spinlock but it changes locking to a potentially less optimal trylock. Put all of that under CONFIG_GENERIC_LOCKBREAK, and introduce a __raw_spin_is_contended that uses the lock data itself to determine whether there are waiters on the lock, to be used if CONFIG_GENERIC_LOCKBREAK is not set. Rename need_lockbreak to spin_needbreak, make it use spin_is_contended to decouple it from the spinlock implementation, and make it typesafe (rwlocks do not have any need_lockbreak sites -- why do they even get bloated up with that break_lock then?).
