Some months ago, you killed the address ranges mechanism from all
sensors i2c chip drivers (both the module parameters and the in-code
address lists). I think it was a very good move, as the ranges can
easily be replaced by individual addresses, and this allowed for
significant cleanups in the i2c core (let alone the impressive size
shrink for all these drivers).
Unfortunately you did not do the same for non-sensors i2c chip drivers.
These need the address ranges even less, so we could get rid of the
ranges here as well for another significant i2c core cleanup. Here comes
a patch which does just that. Since the process is exactly the same as
what you did for the other drivers set already, I did not split this one
in parts.
A documentation update is included.
The change saves 308 bytes in the i2c core, and an average 1382 bytes
for chip drivers which use I2C_CLIENT_INSMOD, 126 bytes for those which
do not.
This change is required if we want to merge the sensors and non-sensors
i2c code (and we want to do this).

The current isofs treatment of hidden files is flawed in two ways. First,
it does not provide sufficient granularity; it hides both 'hidden' files
and 'associated' files (resource fork for Mac files). Second, the default
behavior to completely strip hidden files, while an admirable
implementation of the spec, is a poor choice given the real world use of
hidden files as a poor mans copy protection scheme for MSDOS and Windows
based systems. A longer description of this is available here:
http://www.uwsg.iu.edu/hypermail/linux/kernel/0205.3/0267.html
This patch was originally built after a few private conversations with Alan
Cox; I shamefully failed to persist in seeing it go forward, I hope to make
amends now.
This patch introduces granularity by allowing explicit control for both
hidden and associated files. It also reverses the default so that by
default, hidden files are treated as regular files on the iso9660 file
system.
This allow Wine to process Windows CDs, including those that are hybrid
Mac/Windows CDs properly and completely, without our having to go muck up
peoples fstabs as we do now. (I have tested this with such a hybrid +
hidden CD and have verified that this patch works as claimed).

This series of patches reworks the configuration and internal structure
of the SGI IOC4 I/O controller device drivers.
These changes are motivated by several factors:
- The IOC4 chip PCI resources are of mixed use between functions (i.e.
multiple functions are handled in the same address range, sometimes
within the same register), muddling resource ownership and initialization
issues. Centralizing this ownership in a core driver is desirable.
- The IOC4 chip implements multiple functions (serial, IDE, others not
yet implemented in the mainline kernel) but is not a multifunction
PCI device. In order to properly handle device addition and removal
as well as module insertion and deletion, an intermediary IOC4-specific
driver layer is needed to handle these operations cleanly.
- All IOC4 drivers are currently enabled by a single CONFIG value. As
not all systems need all IOC4 functions, it is desireable to enable
these drivers independently.
- The current IOC4 core driver will trigger loading of all function-level
drivers, as it makes direct calls to them. This situation should be
reversed (i.e. function-level drivers cause loading of core driver)
in order to maintain a clear and least-surprise driver loading model.
- IOC4 hardware design necessitates some driver-level dependency on
the PCI bus clock speed. Current code assumes a 66MHz bus, but the
speed should be autodetected and appropriate compensation taken.
This patch series effects the above changes by a newly and better designed
IOC4 core driver with which the function-level drivers can register and
deregister themselves upon module insertion/removal. By tracking these
modules, device addition/removal is also handled properly. PCI resource
management and ownership issues are centralized in this core driver, and
IOC4-wide configuration actions such as bus speed detection are also
handled in this core driver.
This patch:
The SGI IOC4 I/O controller chip implements multiple functions, though it is
not a multi-function PCI device. Additionally, various PCI resources of the
IOC4 are shared by multiple hardware functions, and thus resource ownership by
driver is not clearly delineated. Due to the current driver design, all core
and subordinate drivers must be loaded, or none, which is undesirable if not
all IOC4 hardware features are being used.
This patch reorganizes the IOC4 drivers so that the core driver provides a
subdriver registration service. Through appropriate callbacks the subdrivers
can now handle device addition and removal, as well as module insertion and
deletion (though the IOC4 IDE driver requires further work before module
deletion will work). The core driver now takes care of allocating PCI
resources and data which must be shared between subdrivers, to clearly
delineate module ownership of these items.

To improve shmem scalability, we allowed tmpfs instances which don't need
their blocks or inodes limited not to count them, and not to allocate any
sbinfo. Which was okay when the only use for the sbinfo was accounting
blocks and inodes; but since then a couple of unrelated projects extending
tmpfs want to store other data in the sbinfo. Whether either extension
reaches mainline is beside the point: I'm guilty of a bad design decision,
and should restore sbinfo to make any such future extensions easier.
So, once again allocate a shmem_sb_info for every shmem/tmpfs instance, and
now let max_blocks 0 indicate unlimited blocks, and max_inodes 0 unlimited
inodes. Brent Casavant verified (many months ago) that this does not
perceptibly impact the scalability (since the unlimited sbinfo cacheline is
repeatedly accessed but only once dirtied).
And merge shmem_set_size into its sole caller shmem_remount_fs.

This patch removes the entwining of cpusets and hotplug code in the "No
more Mr. Nice Guy" case of sched.c move_task_off_dead_cpu().
Since the hotplug code is holding a spinlock at this point, we cannot take
the cpuset semaphore, cpuset_sem, as would seem to be required either to
update the tasks cpuset, or to scan up the nested cpuset chain, looking for
the nearest cpuset ancestor that still has some CPUs that are online. So
we just punt and blast the tasks cpus_allowed with all bits allowed.
This reverts these lines of code to what they were before the cpuset patch.
And it updates the cpuset Doc file, to match.
The one known alternative to this that seems to work came from Dinakar
Guniguntala, and required the hotplug code to take the cpuset_sem semaphore
much earlier in its processing. So far as we know, the increased locking
entanglement between cpusets and hot plug of this alternative approach is
not worth doing in this case.

The driver model has a "detach_state" mechanism that:
- Has never been used by any in-kernel drive;
- Is superfluous, since driver remove() methods can do the same thing;
- Became buggy when the suspend() parameter changed semantics and type;
- Could self-deadlock when called from certain suspend contexts;
- Is effectively wasted documentation, object code, and headspace.
This removes that "detach_state" mechanism; net code shrink, as well
as a per-device saving in the driver model and sysfs.

I have recompiled Linux kernel 2.6.11.5 documentation for me and our
university students again. The documentation could be extended for more
sources which are equipped by structured comments for recent 2.6 kernels. I
have tried to proceed with that task. I have done that more times from 2.6.0
time and it gets boring to do same changes again and again. Linux kernel
compiles after changes for i386 and ARM targets. I have added references to
some more files into kernel-api book, I have added some section names as well.
So please, check that changes do not break something and that categories are
not too much skewed.
I have changed kernel-doc to accept "fastcall" and "asmlinkage" words reserved
by kernel convention. Most of the other changes are modifications in the
comments to make kernel-doc happy, accept some parameters description and do
not bail out on errors. Changed <pid> to @pid in the description, moved some
#ifdef before comments to correct function to comments bindings, etc.
You can see result of the modified documentation build at
http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz

The patch changes the location of EDDBUF in zero-page (as it comes after E820).
