This change was wrong. pfn_to_nid is a macro.

NODE_THRESHOLD got accidentally dropped in the interactive scheduler
changes merge. This puts it back.

Apple PowerBooks want <asm/prom.h> in ohci-pci.c for the prototype of
pci_device_to_OF_node().  This patch adds it to the already present
list of PowerBook specific #includes:

This squashes (gcc-3.2) "label and end of compound statement
deprecated" warnings in usb-serial.c.

Make CONFIG_SYSCTL control sys32_sysctl as well.  Based on a patch from Peter Chubb.

From Rusty Lynch:

* makes sysfs cleanup the buffer->data allocated by the attribute write
functions
* fixes a bug that causes the kernel to oops when somebody attempts to
write to the file.

This patch was previously integrated, but dropped erroneously by a bk 
merge. 

This fixes file cleanup during a sysfs directory removal by deleting files
from ->d_subdirs as they're iterated over, then checking if we can get a
reference on them.

Andy Grover told me this should be posted here.  It allows ACPI to
compile even with PCI turned off.  Patch against 2.5.60.

ia 64 part of the patch.  This gives you a 32 bit version of sys_futex (hopefully).

concurrent renames in another directory.

I doubt this can be triggered in practice, and the fix is
a bit heavy-handed, but let's see if numbers can show that
the simple fix doesn't show any real lock contention.

list.h must now include stddef since it uses NULL.

This is the "boot sector removal" patch for i386 updated for Linux
2.5.63-bk7.  The only change against the 2.5.59 version is that the
FDOPTS Makefile variable, which lets one create a floppy image with
arbitrary kernel options, has been merged from the x86-64 version, and
the comments have been updated.

The patch removes the in-kernel boot sector, which these days rarely
work correctly (it only supports up to 1 MB kernels, and only work on
legacy floppies -- not on IDE or USB devices, nor on any kind of
emulated devices like El Torito), replaces it with a placeholder stub,
and sets up the Makefile targets to create floppies or floppy images
using SYSLINUX.  The FDOPTS Makefile variable can be used to set
kernel command line options (thanks to a suggestion by Andi Kleen.)

Note that the same change has already been applied to the x86-64
architecture.  The last hunk of the patch corrects a comment in that
architecture.

  Now we tackle pci_add_new_bus and pci_scan_bridge.  The hotplug code
  currently uses this, but I'd like it to die off; pci_scan_bridge()
  should be used to scan behind bridges.  This may mean hotplug needs
  some changes to pci_scan_bridge - if so, we need to find out what
  changes are required and fix it.

  pci_alloc_child_bus() does what pci_add_new_bus() did, except it
  doesn't attach the new bus to the parents list of child buses.  The
  only way this bus can be reached from the parent bus is by scanning
  the parents devices list, and locating a device with a non-NULL
  subordinate bus.  The only code which should be doing this is the
  PCI code.

  Since the new bus will have an empty list head for bus->node, we can
  detect unattached buses prety easily.  (see pci-3.diff.)

  pci_scan_bridge() changes slightly - we use our new pci_scan_child_bus()
  function from pci-3.diff, which doesn't attach devices to the global
  tree.  This means callers of pci_scan_child_bus() and pci_scan_bridge()
  (ie, hotplug) will need to call pci_bus_add_devices().

- Convert setup-bus.c resource allocation to scan bus->devices rather
  than bus->children.  As noted previously, newly discovered child
  buses will not be on the parents list of children buses, so when
  we're trying to assign resources, we need to scan the bus for
  devices with subordinate buses rather than using the list of children
  buses.

  The pci_find* functions search using the following lists:
        bus->children   (for subordinate buses)
        pci_root_buses  (for all root buses)
        pci_devices     (for devices)

  This leaves one list which we can add devices to without any drivers
  finding the new devices before we've finished with them.

- initialise bus->node list head.

- pci_scan_slot will scan the specified slot, and add the discovered
  devices to the bus->devices list only.  These devices will not
  appear on the global device list, and do not show in sysfs, procfs.
  pci_scan_slot returns the number of functions found.  If you want
  to find the devices, you have to scan bus->devices and look for
  devices where list_empty(&dev->global_list) is true.

- new function "pci_bus_add_devices" adds newly discovered devices
  to the global device lists, and handles the sysfs and procfs
  stuff, making the devices available to drivers.  All our buses
  which have an empty list head are treated as "new" (since they
  are not attached to the parent buses list of children) and are
  also added.  Currently, no buses will be in this state when this
  function is called.

- new function "pci_scan_child_bus" scans a complete bus, building
  a list of devices on bus->devices only, performing bus fixups
  via pcibios_fixup_bus() and scanning behind bridges.  It does
  make devices externally visible.

- pci_do_scan_bus retains its original behaviour - ie, it scans
  and makes devices available immediately.

- Eliminate the stack allocation of a struct pci_dev, and make
  pci_scan_slot() take a bus and a devfn argument.
- Add "dev->multifunction" to indicate whether this is a multifunction
  device.
- Run header fixups before inserting the new pci device into any
  device lists or announcing it to the drivers.
- Convert some more stuff to use the list_for_each* macro(s).

- Separate out bus resource allocator (pci_bus_alloc_resource)
- Provide pci_enable_bridges to setup command register for all
  pci bridges.

The outbsync one has further changes to come in the next batch to sort
out some platforms like PPC

Also fix the irq masking bug

This switches ide-dma to ide_execute_command and makes IDE DMA also happy
when running shared IRQ

This doesn't have the new -ac testing stuff from 2.4.21pre5-ac but it
has the stuff I now trust in it. This fixes the cache flush stuff and
also means ide-disk now should be safe shared IRQ

Dave Woodhouse did this a while ago and its been kicking around in my
tree just fine. This gets rid of a lot of the init lists of functions
still left in the kernel by having an __init type array built up for the
consoles as well

We must not look for a PCI IRQ for a non native mode IDE device
We must write PCI_INTERRUPT_LINE for VIA

ALi Magik requires workarounds for TV chips
IDE controllers require proper handling in legacy mode
PXB must be disabled on C0 450NX or the IDE will corrupt memory
VIA northbridge devices require the interrupt line is written
NEC_CBUS_2/3 require ISA DMA workarounds
