The Compaq PCI Hotplug driver was creating 2 sysfs files that contained
nothing but debug information, and had way more than "one value" in
them. This patch converts the code to use debugfs for these files
instead.
Compile tested only.

Here's a small patch to reduce the nr. of pointer dereferences in
drivers/pci/hotplug/pciehp_core.c
Benefits:
- micro speed optimization due to fewer pointer derefs
- generated code is slightly smaller
- small line length cleanup
- better readability

Here's a small patch to reduce the nr. of pointer dereferences in

Benefits:
- micro speed optimization due to fewer pointer derefs
- generated code should be slightly smaller
- better readability
note: due to lack of both hardware and cross-compile tools this patch is,
unfortunately, completely untested.

The powerpc PCI code sets up the PCI tree without doing config space
accesses in most cases, from the firmware tree. However, it still wants
to call pci_cfg_space_size() under some conditions, thus it needs to
be made non-static (though I don't see a point to export it to modules).

Add a warning if a child bus may be inaccessible because the
parent bridge has wrong secondary or subordinate bus numbers.
Note that this may or may not happen on "transparent" bridges,
as can be seen in bug #5557.
Also, if we do not fix up the assignment of bus numbers, try to
make use of the bus number space available.

This patch disables power fault, MRL sensor and presence detection
interrupts when a PCIe slot is powered-off and enables those
interrupts when it is powered-on again. This is necessary to prevent
the associated events from causing an endless cycle of interrupts
due to the power-fault bit, which stays set till power is restored
to the slot.

I've implemented a quirk to take advantage of the 1KB I/O space
granularity option on the Intel P64H2 PCI Bridge. I had to change
probe.c because it sets the resource start and end to be aligned on 4k
boundaries (after the quirk sets them to 1k boundaries). I've tested
this patch on a Unisys ES7000-600 both with and without the 1KB option
enabled. I also tested this on a 2 processor Dell box that doesn't have
a P64H2 to make sure there were no negative affects there.

The RPAPHP code contains two routines that appear to be gratuitous copies
of very similar pci code. In particular,
rpaphp_claim_resource ~~ pci_claim_resource
(there is a minor, non-functional difference)
rpadlpar_claim_one_bus == pcibios_claim_one_bus
(the code is identical)
This patch removes the rpaphp versions of the code.

Current SHPCHP driver uses msleep_interruptible() function to wait for
a command completion event. But I think this would cause an unnecessary
long wait until timeout, if command completion interrupt came before
task state was changed to TASK_INTERRUPTIBLE. This patch fixes this
issue. With this patch, command completion becomes faster as follows:
o Without this patch
# time echo 1 > power
real 0m4.708s
user 0m0.000s
sys 0m0.524s
o With this patch
# time echo 1 > power
real 0m2.221s
user 0m0.000s
sys 0m0.532s

Current SHPCHP driver writes a '0' to the Command Completion Detect
bit to clear the Command Complete Interrupt Pending. But according to
the SHPC spec (See 4.7.3.1 System Interrupts), SHPCHP driver must
write '1'. This patch fixes this bug.

This is a major update to the cyblafb framebuffer driver. Most
of the stuff has been tested in the mm tree.
Main advantages:
============
- vxres > xres support
- ywrap and xpan support
- much faster for almost all modes (e.g. 1280x1024-16bpp
draws more than 41 full screens of text instead of about 25
full screens of text per second on authors Epia 5000)
- module init/exit code fixed
- bugs triggered by console rotation fixed
- lots of minor improvements
- startup modes suitable for high performance scrolling
in all directions
This diff also contains a lot of white space fixes.
No side effects are possible, only one single graphics core is affected.

01 enabled. These boards can be identified by having PCI id 1471:8801
or 1471:8811.
- Increased DMA buffer from 512 to 4096 seems to fix audio distortion.

cx88-alsa module is compiled.
