The maple bus driver that went into the kernel mainline in September 2007
contained some bugs which were revealed by the update of the kobj code
for the current release series. Unfortunately those bugs also helped
ensure maple devices were properly detected. This patch (against the
current git) now ensures that devices are properly detected again.(A previous attempt to fix this by delaying initialisation only partially
fixed this - as became apparent when the bus was fully loaded)Signed-off-by: Adrian McMenamin

Improve device detection for maple through longer delay
Experience suggests that a much longer delay in setting up the Maple bus
on the Dreamcast leads to better hardware detection.Signed-off-by: Adrian McMenamin

Replacement second-in-series patch:
This patch fixes up memory leaks and, by delaying initialisation, makes
device detection more robust.It also makes clearer the difference between struct maple_device and
struct device, as well as cleaning up the interrupt request code
(without changing its function in any way).Also now removes redundant registration checking.

This patch is fundamentally about fixing up the whitespace problems
introduced by my previous patch (that brought the code into mainline). A
second patch will follow that will fix memory leaks. The two need to be
applied sequentially.Signed-off-by: Adrian McMenamin

The Maple bus is SEGA's proprietary serial bus for peripherals
(keyboard, mouse, controller etc). The bus is capable of some
(limited) hotplugging and operates at up to 2 M/bits.Drivers of one sort or another existed/exist for 2.4 and a rudimentary
port, which didn't support the 2.6 device driver model was also in
existence.This driver - for the bus logic itself and for the keyboard (other
drivers will follow) are based on the code and concepts of those old
drivers but have lots of completely rewritten parts.I have the maple bus code as a built in now as that seems the sane and
rational way to handle something like that - you either want the bus
or you don't.Signed-off-by: Adrian McMenamin

Transform some calls to kmalloc/memset to a single kzalloc (or kcalloc).
Here is a short excerpt of the semantic patch performing
this transformation:@@

This extends the API somewhat to allow for platform-specific VCR reading and
writing. Some platforms (like SH4-202) implement the VCR in a split VCRL and
VCRH, but end up being in reverse order or have other quirks that need to be
dealt with, so we add a set of superhyway_ops per-bus to accomodate this.We also have to extend the per-device resources somewhat, as some devices now
conveniently split control and data blocks. So we allow a platform to
register its set of SuperHyway devices via superhyway_add_devices() with the
control block always ordered as the first resource (as this is the one that
userspace cares about).Signed-off-by: Paul Mundt

I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch. This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other. So if any
hunk rejects or gets in the way of other patches, just drop it. My scripts
will pick it up again in the next round.Signed-off-by: Tim Schmielau

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
