Convert PCI hotplug skeleton driver to use goto for error handling in
init_slots to avoid code duplication.

Add __init and __exit to some functions only called from __init/__exit context.

Coding style fixes for pcihp_skeleton.c: remove spaces before opening braces
and change a comment in function hardware_test to make clearer that the
functions purpose is not to tell the user there are no tests.

This one removes all the useless NULL checks including slot_paranoia_check,
get_slot and the magic number from the PCI hotplug skeleton driver. Also some
lines containing only a single tab are fixed.

Convert the PCI hotplug skeleton driver to use new style of module parameter
handling.

If there is a condition with the comment "should never happen" it is a good
place for a BUG() if it is ever reached.

Some minor coding style fixes:
-space before opening brace of function
-wrap some long lines
-change some identations from spaces to tabs

This one fixes another space before an opening brace I missed before and
optimizes the error paths in init_slots a bit more.

The magic slot number was only another type of checking the validity of a
pointer. These checks are all gone so magic can follow them.

This one converts acpiphp_core.c to use the new interface for module
parameters.

Convert the driver to use new interface for module parameters, Also fix the
driver name used in debug messages.

slot->magic is not used anymore since slot_paranoia_check is dead, so just kill
it.

A special function for handling the parameters in non-module case is not
needed, the MODULE_* makros handle this also for compiled in situations.

If we remove this 3 get_* functions the pci hotplug core will do the same
thing for us.

Fix 2 very ugly return constructs.

This one converts the error handling in init_slots to use gotos to avoid code
duplication.

The function hardware_test only tells that there are no tests. If we just
kill it the file "test" in the slot's directory will not show up which
means pretty much the same.

This patch kills the space before the opening brace in function
declarations. It also beautifies some ugly return statements.

Fixed.

If the "struct hotplug_struct *" parameter to any function in
hotplug_slots_ops is ever NULL something bogus is going on. In this case we
should just oops and not hide the bug. This also fixes the driver name used in
debug messages.

Attached patch fix the problem I have found during DLPAR I/O slots
testing on our new hardware.  rpaphp needs to set eeh-option(eanbled)
for newly added IOA prior to performing PCI config(pci_setup_device),
otherwise the pci_dev of the IOA will have invalid base address
information.

Linas Vepstas impleted eeh changes.

The messages read:

PCI: Address space collision on region 8 of bridge 0000:00:1f.0 [1180:11bf]
PCI: Ignoring BAR0-3 of IDE controller 0000:00:1f.1
Transparent bridge - 0000:00:1e.0
PCI: Using IRQ router PIIX/ICH [8086/24cc] at 0000:00:1f.0
PCI: Found IRQ 11 for device 0000:00:1f.1

The following patch adds "PCI: " in front of the message and KERN_INFO as well.
Compile&boot tested.

Can you please feed the following patch to Andrew?

into ppc970.osdl.org:/home/torvalds/v2.6/linux

a ppc64 tree.

into kernel.bkbits.net:/home/davem/net-2.6

More functions and data that should be static.

Thanks to Dru <andru@treshna.com>, who provided an easy way to reproduce
the problem.

What we have in lib/rwsem.c:__rwsem_do_wake():
	int woken, loop;
	^^^
and several lines below:
	loop = woken;
	woken *= RWSEM_ACTIVE_BIAS-RWSEM_WAITING_BIAS;
	woken -= RWSEM_ACTIVE_BIAS;

However, rw_semaphore->count is 64-bit on Alpha, so
RWSEM_WAITING_BIAS has been defined as -0x0000000100000000L.
Obviously, this blows up in the write contention case.

Fix new ISDN CAPI's internal ncci list semaphore if
CONFIG_ISDN_CAPI_MIDDLEWARE is disabled.

Thanks to Florian Schirmer.
