The ns_cgroup is an annoying cgroup at the namespace / cgroup frontier and
leads to some problems:* cgroup creation is out-of-control
* cgroup name can conflict when pids are looping
* it is not possible to have a single process handling a lot of
namespaces without falling in a exponential creation time
* we may want to create a namespace without creating a cgroupThe ns_cgroup was replaced by a compatibility flag 'clone_children',
where a newly created cgroup will copy the parent cgroup values.
The userspace has to manually create a cgroup and add a task to
the 'tasks' file.This patch removes the ns_cgroup as suggested in the following thread:
https://lists.linux-foundation.org/pipermail/containers/2009-June/018616.html
The 'cgroup_clone' function is removed because it is no longer used.
This is a userspace-visible change. Commit 45531757b45c ("cgroup: notify
ns_cgroup deprecated") (merged into 2.6.27) caused the kernel to emit a
printk warning users that the feature is planned for removal. Since that
time we have heard from XXX users who were affected by this.Signed-off-by: Daniel Lezcano

Instead of looping over each irq and checking against the irq array
bounds, adjust the bounds before looping.The old code will not free any irq if the irq + count is above
irq_virq_count because the test in the loop is testing irq + count
instead of irq + i.This code checks the limits to avoid unsigned integer overflows.

The radix-tree code uses call_rcu when freeing internal elements.
We must protect against the elements being freed while we traverse
the tree, even if the returned pointer will still be valid.While preparing a patch to expand the context in which
irq_radix_revmap_lookup will be called, I realized that the
radix tree was not locked.When asked
For a normal call_rcu usage, is it allowed to read the structure in
irq_enter / irq_exit, without additional rcu_read_lock? Could an
element freed with call_rcu advance with the cpu still between
irq_enter/irq_exit (and irq_disabled())?Paul McKenney replied:
Absolutely illegal to do so. OK for call_rcu_sched(), but a
flaming bug for call_rcu().And thank you very much for finding this!!!
Further analysis:
In the current CONFIG_TREE_RCU implementation. CONFIG_TREE_PREEMPT_RCU
(and CONFIG_TINY_PREEMPT_RCU) uses explicit counters.These counters are reflected from per-CPU to global in the
scheduling-clock-interrupt handler, so disabling irq does prevent the
grace period from completing. But there are real-time implementations
(such as the one use by the Concurrent guys) where disabling irq
does -not- prevent the grace period from completing.While an alternative fix would be to switch radix-tree to rcu_sched, I
don't want to audit the other users of radix trees (nor put alternative
freeing in the library). The normal overhead for rcu_read_lock and
unlock are a local counter increment and decrement.This does not show up in the rcu lockdep because in 2.6.34 commit
2676a58c98 (radix-tree: Disable RCU lockdep checking in radix tree)
deemed it too hard to pass the condition of the protecting lock
to the library.Signed-off-by: Milton Miller

Look up the descriptor and check that it is found in handle_one_irq
before checking if we are on the irq stack, and call the handler
directly using the descriptor if we are on the stack.We need check irq_to_desc finds the descriptor to avoid a NULL
pointer dereference. It could have failed because the number from
ppc_md.get_irq was above NR_IRQS, or various exceptional conditions
with sparse irqs (eg race conditions while freeing an irq if its was
not shutdown in the controller).fe12bc2c99 (genirq: Uninline and sanity check generic_handle_irq())
moved generic_handle_irq out of line to allow its use by interrupt
controllers in modules. However, handle_one_irq is core arch code.
It already knows the details of struct irq_desc and handling irqs in
the nested irq case. This will avoid the extra stack frame to return
the value we don't check.Signed-off-by: Milton Miller

Since kmem caches are allocated before init_IRQ as noted in 3af259d155
(powerpc: Radix trees are available before init_IRQ), we now call
kmalloc in all cases and can can always call kfree if we are asked

The comment claims we will call host->ops->map() to update the flags if

Rename functions and arguments to reflect current usage. iic_cause_ipi
becomes iic_message_pass and iic_ipi_to_irq becomes iic_msg_to_irq,
and iic_request_ipi now takes a message (msg) instead of an ipi number.
Also mesg is renamed to msg.Commit f1072939b6 (powerpc: Remove checks for MSG_ALL and
MSG_ALL_BUT_SELF) connected the smp_message_pass hook for cell to the
underlying iic_cause_IPI, a platform unique name. Later 23d72bfd8f
(powerpc: Consolidate ipi message mux and demux) added a cause_ipi
hook to the smp_ops, also used in message passing, but for controllers
that can not send 4 unique messages and require multiplexing. It is
even more confusing that the both take two arguments, but one is the
small message ordinal and the other is an opaque long data associated
with the cpu.Since cell iic maps messages one to one to ipi irqs, rename the
function and argument to translate from ipi to message. Also make it
clear that iic_request_ipi takes a message number as the argument
for which ipi to create and request.No functionional change, just renames to avoid future confusion.

The cell iic interrupt controller has enough software caused interrupts
to use a unique interrupt for each of the 4 messages powerpc uses.
This means each interrupt gets its own irq action/data combination.Use the seperate, optimized, arch common ipi action functions
registered via the helper smp_request_message_ipi instead passing the
message as action data to a single action that then demultipexes to
the required acton via a switch statement.smp_request_message_ipi will register the action as IRQF_PER_CPU
and IRQF_DISABLED, and WARN if the allocation fails for some reason,
so no need to print on that failure. It will return positive if
the message will not be used by the kernel, in which case we can
free the virq.In addition to elimiating inefficient code, this also corrects the
error that a kernel built with kexec but without a debugger would
not register the ipi for kdump to notify the other cpus of a crash.This also restores the debugger action to be static to kernel/smp.c.

Commit 0837e3242c73566fc1c0196b4ec61779c25ffc93 fixes a situation on POWER7
where events can roll back if a specualtive event doesn't actually complete.
This can raise a performance monitor exception. We need to catch this to ensure
that we reset the PMC. In all cases the PMC will be less than 256 cycles from
overflow.This patch lifts Anton's fix for the problem in perf and applies it to oprofile
as well.Signed-off-by: Eric B Munson

This patch implements the raw syscall tracepoints on PowerPC and exports
them for ftrace syscalls to use.To minimise reworking existing code, I slightly re-ordered the thread
info flags such that the new TIF_SYSCALL_TRACEPOINT bit would still fit
within the 16 bits of the andi. instruction's UI field. The instructions
in question are in /arch/powerpc/kernel/entry_{32,64}.S to and the
_TIF_SYSCALL_T_OR_A with the thread flags to see if system call tracing
is enabled.In the case of 64bit PowerPC, arch_syscall_addr and
arch_syscall_match_sym_name are overridden to allow ftrace syscalls to
work given the unusual system call table structure and symbol names that
start with a period.Signed-off-by: Ian Munsie

Most arches define CONFIG_DEBUG_STACK_USAGE exactly the same way. Move it
to lib/Kconfig.debug so each arch doesn't have to define it. This
obviously makes the option generic, but that's fine because the config is
already used in generic code.It's not obvious to me that sysrq-P actually does anything caution by
