isa: Make the remove callback for isa drivers return void

Annotate hardware config module parameters in drivers/i2c/
When the kernel is running in secure boot mode, we lock down the kernel to prevent userspace from modifying the running kernel image. Whilst this includes prohibiting access to things like /dev/mem, it must also prevent access by means of configuring driver modules in such a way as to cause a device to access or modify the kernel image.
To this end, annotate module_param* statements that refer to hardware configuration and indicate for future reference what type of parameter they specify. The parameter parser in the core sees this information and can skip such parameters with an error message if the kernel is locked down. The module initialisation then runs as normal, but just sees whatever the default values for those parameters is.
Note that we do still need to do the module initialisation because some drivers have viable defaults set in case parameters aren't specified and some drivers support automatic configuration (e.g. PNP or PCI) in addition to manually coded parameters.
This patch annotates drivers in drivers/i2c/.

ret is still -1, if during the polling read_byte() returns at once with I2C_PCA_CON_SI set. So ret > 0 would lead *_waitforcompletion() to return 0, in spite of the proper behavior.
The routine was rewritten, so that ret has always a proper value, before returning.

i2c-pca-isa: Don't grab arbitrary resources
Grabbing ISA bus resources without anything or anyone telling us we should can break boot on randconfig/allyesconfig builds by keeping resources that are in fact owned by different hardware busy and does as reported by Ingo Molnar.
Generally it's also dangerous to just poke at random I/O ports and especially those in the range where other old easily confused ISA hardware might live.
For this specialized I2C bus driver, insist that the user specifies the resources before grabbing them.
The^WA user of this driver is a one time
echo "options i2c-pca-isa base=0x330 irq=10" >> /etc/modprobe.conf

i2c-algo-pca: Extend for future drivers
The separation between algorithm and adapter was unsharp at places. This was partly hidden by the fact, that the ISA-driver allowed just one instance and had all private data in static variables. This patch makes neccessary preparations to add a platform driver on top of the algorithm, while still supporting ISA. Note: Due to lack of hardware, the ISA-driver could not be tested except that it builds.
Concerning the core struct i2c_algo_pca_data:
- A private data field was added, all hardware dependant data may go here. Similar to other algorithms, now a pointer to this data is passed to the adapter's functions. In order to make as less changes as possible to the ISA-driver, it leaves the private data empty and still only uses its static variables.
- A "reset_chip" function pointer was added; such a functionality must come from the adapter, not the algorithm.
- use a variable "i2c_clock" instead of a function pointer "get_clock", allowing for write access to a default in case a wrong value was supplied.
In the algorithm-file:
- move "i2c-pca-algo.h" into "linux/i2c-algo-pca.h" - now using per_instance timeout values (i2c_adap->timeout) - error messages specify the device, not only the driver name - restructure initialization to easily support "i2c_add_numbered_adapter" - drop "retries" and "own" (i2c address) as they were unused
(The state-machine for I2C-communication was not touched.)
In the ISA-driver:
- adapt to new algorithm

PCI: Cleanup the includes of <linux/pci.h>
I noticed that many source files include <linux/pci.h> while they do not appear to need it. Here is an attempt to clean it all up.
In order to find all possibly affected files, I searched for all files including <linux/pci.h> but without any other occurence of "pci" or "PCI". I removed the include statement from all of these, then I compiled an allmodconfig kernel on both i386 and x86_64 and fixed the false positives manually.
My tests covered 66% of the affected files, so there could be false positives remaining. Untested files are:

I would welcome test reports for these files. I am fine with removing the untested files from the patch if the general opinion is that these changes aren't safe. The tested part would still be nice to have.

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel.
The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()).
Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling.
Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing.
I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations.
This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
struct pt_regs *old_regs = set_irq_regs(regs);
And put the old one back at the end:
set_irq_regs(old_regs);
Don't pass regs through to generic_handle_irq() or __do_IRQ().
In timer_interrupt(), this sort of change will be necessary:
- update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING);
I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode().
Some notes on the interrupt handling in the drivers:
(*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct.
(*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not.
(*) Various IRQ handler function pointers have been moved to type irq_handler_t.
