[PATCH] PCI Hotplug: add common acpi functions to core

shpchprm_acpi.c and pciehprm_acpi.c are nearly identical.  In addition,
there are functions in both these files that are also in acpiphp_glue.c.
This patch will remove duplicate functions from shpchp, pciehp, and
acpiphp and move this functionality to pci_hotplug, as it is not
hardware specific.  Get rid of shpchprm* and pciehprm* files since they
are no longer needed.  shpchprm_nonacpi.c and pciehprm_nonacpi.c are
identical, as well as shpchprm_legacy.c and can be replaced with a
macro.

This patch also changes acpiphp to use the common hpp code.

[PATCH] acpiphp: Scan slots under the nested P2P bridge

Because some dock stations do not have pci bridges or pci devices that

[PATCH] PCI: PCI/Cardbus cards hidden, needs pci=assign-busses to fix

"In some cases, especially on modern laptops with a lot of PCI and cardbus
bridges, we're unable to assign correct secondary/subordinate bus numbers
to all cardbus bridges due to BIOS limitations unless we are using
"pci=assign-busses" boot option." -- Ivan Kokshaysky (from a patch comment)

Without it, Cardbus cards inserted are never seen by PCI because the parent
PCI-PCI Bridge of the Cardbus bridge will not pass and translate Type 1 PCI
configuration cycles correctly and the system will fail to find and
initialise the PCI devices in the system.

Reference: PCI-PCI Bridges: PCI Configuration Cycles and PCI Bus Numbering:
http://www.science.unitn.it/~fiorella/guidelinux/tlk/node72.html

The reason for this is that:
 ``All PCI busses located behind a PCI-PCI bridge must reside between the
secondary bus number and the subordinate bus number (inclusive).''

"pci=assign-busses" makes pcibios_assign_all_busses return 1 and this
turns on PCI renumbering during PCI probing.

Alan suggested to use DMI automatically set assign-busses on problem systems.

The only question for me was where to put it.  I put it directly before
scanning PCI bus into pcibios_scan_root() because it's called from legacy,
acpi and numa and so it can be one place for all systems and configurations
which may need it.

AMD64 Laptops are also affected and fixed by assign-busses, and the code is
also incuded from arch/x86_64/pci/ that place will also work for x86_64
kernels, I only ifdef'-ed the x86-only Laptop in this example.

Affected and known or assumed to be fixed with it are (found by googling):

* ASUS Z71V and L3s
* Samsung X20
* Compaq R3140us and all Compaq R3000 series laptops with TI1620 Controller,
  also Compaq R4000 series (from a kernel.org bugreport)
* HP zv5000z (AMD64 3700+, known that fixup_parent_subordinate_busnr fixes it)
* HP zv5200z
* IBM ThinkPad 240
* An IBM ThinkPad (1.8 GHz Pentium M) debugged by Pavel Machek

* MSI S260 / Medion SIM 2100 MD 95600

Yes. However, it's pretty clear that the e820 entries are there for a
reason. Probably they are a hack by the BIOS maintainers to keep Windows
from stomping/moving that region, exactly because they want to keep the
bridge where it is (or, it's actually for the BIOS itself - the BIOS
tables are a horrid mess, and BIOS engineers are pretty hacky people:
they'll add random entries to make their own broken algorithms do the
"right thing").

I think we could (and probably should) solve this another way: consider
the ACPI "reserved regions" from the e820 map exactly the same way that we
do other ACPI hints - they should restrict _new_ allocations, but not
impact stuff we figure out on our own.

Basically, right now we assign _unassigned_ resources at "fs_initcall"
time. If we were to add in the e820 "reserved region" stuff before that
(but after we've done PCI discovery), we'd probably do the right thing.

Right now we do the e820 reserved regions very early indeed: we call
"register_memory()" from setup_arch(). We could move at least part of it
(the part that registers the resources) down a bit.

Here's a test-patch. I'm not saying we should absolutely do this, but it
might be interesting to try...

Agreed, looks like an accident.  The patch [1] originally came from Kip

probing behind pci_scan_bridge.  It is undeseriable to disable
PCI_BRIDGE_CTL_MASTER_ABORT in pci_{read,write)_config_* and the
behaviour wasn't considered a bug in need of a workaround, so this was
put in probe.c.

[PATCH] PCI: Give PCI config access initialization a defined ordering

This avoids problems with the linker reordering them and the
less useful PCI config space access methods taking priority
over the better ones.

[PATCH] shpchp - Fix incorrect return value of interrupt handler

Current SHPCHP driver has a bug in its interrupt handler which cause
"IRQ #: nobody cared" oops. This problem can be reproduced easily by
the following operation.

    # cd /sys/bus/pci/slots/<slot#>
    # while true; do echo 1 > attention ; done &

The reason is that when command complete interrupt is raised, current
SHPCHP driver's interrupt handler returns IRQ_NONE regardless of if
the interrupt is handled or not.

This patch fixes this issue.

[PATCH] __GENERIC_PER_CPU changes

Now CONFIG_DEBUG_INITDATA is in, initial percpu data
[__per_cpu_start,__per_cpu_end] can be declared as a redzone, and invalid
accesses after boot can be detected, at least for i386.

We can let non possible cpus percpu data point to this 'redzone' instead of
NULL .

NULL was not a good choice because part of [0..32768] memory may be
readable and invalid accesses may happen unnoticed.

If CONFIG_DEBUG_INITDATA is not defined, each non possible cpu points to
the initial percpu data (__per_cpu_offset[cpu] == 0), thus invalid accesses
wont be detected/crash.
