ok, i've created a new tip/irq/sparseirq topic branch for this.

Could you please send future updates against:

git-checkout tip/master
git-merge tip/irq/sparseirq

Not yet integrated into tip/master, i've still got some other backlog.

A couple of observations about the general structure of the sparse irqs
code:

- the new APIs should probably live in mm/bootmem.c not in init/main.c,
and in bootmem.h. Also, it should be outlined clearly why this new API
is needed as a wrapper ontop of existing bootmem mechanisms.

- the #ifdef complications, while fine for migration, should be
eliminated. Could we introduce some compatible form for the
definition/allocation APIs that work even if an architecture still
uses a flat irq array? That would remove most of the uglinesses.

- some of the irq < 16 checks in x86 look a bit ugly, can we do anything
about them?

- i think as a final-ish commit we should just remove the dyn-array
define and make all architectures use this facility. You converted
most of them - how many are still missing? Sparse-irq is more
intrusive so that should probably stay a Kconfig knob.

- there was one aspect of NR_IRQS that was nice and useful: it acted as
a sanity check against BIOS bugs and driver bugs that pass in some
irrealistically high irq number. Now we'll just try to allocate some
really high IRQ and accept it. I _think_ there should be a single,
simple 'absolute maximum IRQ number' define which should set the
maximum possible IRQ number. Lets call it NR_IRQS_MAX or so, and set
it to NR_CPUS*NR_IO_APICS*224 or so?

- i'm a bit worried about linecount increase in general:

247 files changed, 3671 insertions(+), 2052 deletions(-)

could we work on reducing that somewhat? The new infrastructure bits
in mm/* and kernel/irq/* will be unavoidable, what we should
concentrate on is to make usage of the new facility just as
straightforward, easy and compact as the old irq_desc[] usages.
A worst-case example is drivers/char/random.c: the
CONFIG_HAVE_SPARSE_IRQ and CONFIG_HAVE_DYN_ARRAY #ifdef jungle is not
acceptable. I think the best way out is to convert the whole kernel to
the new facilities (as safely as possible, without breaking other
architectures), and making sure that the end result is easy to
understand and intuitive.

so i dont mind the current code as long as the extra complications are
temporary during a safe conversion - but we should work on eliminating
all those complications before thinking about upstream merging.

the irq/sparseirq git tree can be picked up from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git irq/sparseirq

[ note, the diffstat has x86/core and some other topics that your
patches had dependencies on. Patch not included as vger would choke on
its 700K size. ]
