Commit 63d95a91 ('workqueue: use @pool instead of @gcwq or @cpu where
applicable') changes an approach to access nr_running.
Thus, wq_worker_waking_up() doesn't use @cpu anymore.
Remove it and remove comment related to it.

After try_to_grab_pending(), __queue_delayed_work() is invoked
in mod_delayed_work_on(). When @delay == 0, we can call __queue_work()
directly in order to avoid setting useless timer.

This patchset do minor cleanup for workqueue code.
First patch makes minor behavior change, however, it is trivial.
Others doesn't makes any functional difference.
These are based on v3.7-rc1

This optimization doesn't matter much. But this prepares the
arch headers that we need to add a new API in order to detect
when the arch can trigger self IPIs to implement the irq work.
This is necessary later to make printk working in nohz CPUs.

While queuing an irq work, let the caller choose between
triggering a self-IPI right away, provided the arch is able
to do so, or waiting for the next timer interrupt to run the work.
Some non-urgent enqueuers like printk may prefer not to raise
an IPI storm in case of frequent calls on short
Hi,
So the design is not quite the same here. Instead of using the ad hoc
printk_tick() in periodic mode and irq_work on nohz mode, printk
is now always using irq_work.
In turn, irq_work subsystem is able to let enqueuers choose between IPI
or lazy tick hook to execute works, and that in order
If we enqueue a work while in dyntick idle mode and the arch doesn't
have self-IPI support, we may not find an opportunity to run the work
before a while.
In this case, exit the idle loop to re-evaluate irq_work_needs_cpu()
and restart the tick.

klogd is woken up asynchronously from the tick in order
to do it safely.
However if printk is called when the tick is stopped, the reader
won't be woken up until the next interrupt, which might not fire
before a while. As a result, the user may miss some message.
To fix this, lets implement the
irq work is supposed to work everywhere because of the irq work
hook in the generic timer tick function.
I might be missing something though...

We need some quick way to check if the CPU has stopped
its tick. This will be useful to implement the printk tick
using the irq work subsystem.

Peter,
Thomas suggested that I email you to decide if a bug I stumbled on with
binutils should be cause to blacklist version 2.21. Note, testing
against 2.22 does not show this issue.
A couple of days ago I went to test 3.6.1-rt2 and while building the
i386 kernel, the build failed. I first

kmalloc() and kmalloc_node() of the SLUB isn't inlined when @flags = __GFP_DMA.
This patch optimize this case,
so when @flags = __GFP_DMA, it will be inlined into generic code.

kmalloc() and kmalloc_node() is always inlined into generic code.
However, there is a mistake in implemention of the SLUB.
In kmalloc() and kmalloc_node() of the SLUB,
we try to compare kmalloc_caches[index] with NULL.
As it cannot be known at compile time,
this comparison is inserted into
