cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

d54b1fdb1d [PATCH] mark struct file_operations const 5
Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

3e643e77a9 Altix: Add ACPI SSDT PCI device support (hotplug)
Support for dynamic loading and unloading of ACPI SSDT tables upon slot
hotplugs and unplugs.

On SN platforms, we now represent every populated root bus slot with a single
ACPI SSDT table containing info for every device and PPB attached to the slot.
 These SSDTs are generated by the prom at initial boot and hotplug time.  The
info in these SSDT tables is used by the SN kernel IO "fixup" code (which is
called at boot and hotplug time).

On hotplugs (i.e.  enable_slot()), if running with an ACPI capable prom,
attempt to obtain a new ACPI SSDT table for the slot being hotplugged.  If
successful, add the table to the ACPI namespace (acpi_load_table()) and then
walk the new devices and add them to the ACPI infrastructure (acpi_bus_add()).

On hot unplugs (i.e.  disable_slot()), if running with an ACPI capable prom,
attempt to remove the SSDT table associated with the slot from the ACPI
namespace (acpi_unload_table_id()) and infastructure (acpi_bus_trim()).

From: John Keller <jpk@sgi.com>

 A bug was fixed where the sgi hotplug driver was removing
 the slot's SSDT table from the ACPI namespace a bit too early in
 disable_slot(). Also, we now call acpi_bus_start() subsequent
 to acpi_bus_add().

mode.

ac9e989187 PCI: Change memory allocation for acpiphp slots
Change memory allocation for acpiphp slots

Change the "struct slot" that acpiphp uses for managing it's slots to
directly contain the memory for the needed struct hotplug_slot_info and
the slot's name. This way we need only two memory allocations per slot
instead of four.

While we are at it: make_slot_name() is just a wrapper around snprintf()
knowing the right arguments to call it. Since the function makes just one
function call and is only called from one place I inlined it by hand.

Finally this fixes a possible bug waiting for someone to hit it. There were
two unused local variables in acpiphp_register_hotplug_slot(). gcc did not
find them because they were used in memory allocations with sizeof(*var).
They had the same types as the target of the allocation, but nevertheless
this was just weird.

467c442f09 acpiphp: fix use of list_for_each macro
This patch fixes invalid usage of list_for_each()

list_for_each (node, &bridge_list) {
	bridge = (struct acpiphp_bridge *)node;
	...
}

This code works while the member of list node is located at the
head of struct acpiphp_bridge.

9f581f162e Altix: SN ACPI hotplug support.
A few minor changes to the way slot/device fixup is done.

No need to be calling sn_pci_controller_fixup(), as
a root bus cannot be hotplugged.

35ae61a0f4 acpiphp: fix latch status
pci_hotplug.h says:

 * @latch_status: if the latch (if any) is open or closed (1/0)

However, acpiphp returns opposite value.
This patch fixes this issue.

I tested this patch on my ia64 machine that has some apciphp based
hotplug slots.

7a54f25cef PCI Hotplug: move pci_hotplug.h to include/linux/
This makes it possible to build pci hotplug drivers outside of the main
kernel tree, and Sam keeps telling me to move local header files to

49c61cca2b cpcihp_generic: prevent loading without "bridge" parameter
cpcihp_generic module requires configured "bridge" module parameter.
But it can be loaded successfully without that parameter.
Because module init call ends up returning positive value.

This patch prevents from loading without setting "bridge" module parameter.

662a98fb8d PCI hotplug: ioremap balanced with iounmap
1. ioremap must be balanced by an iounmap and failing to do so can
   result in a memory leak.
2. Handle return value correctly

Tested (compilation only) with:
- allmodconfig
