This patch implements the following calls to set and retrieve a task's
CPU affinity:

    int sched_setaffinity(pid_t pid, unsigned int len,
    				      unsigned long *new_mask_ptr)
    int ched_getaffinity(pid_t pid, unsigned int len,
    				      unsigned long *user_mask_ptr)

	a) part of open_namei() done after we'd found vfsmount/dentry of
the object we want to open had been split into a helper - may_open().

	b) do_open() in fs/nfsctl.c didn't do any permission checks on
the nfsd file it was opening - sudden idiocy attack on my part (I missed
the fact that dentry_open() doesn't do permission checks - open_namei()
does).  Fixed by adding obvious may_open() calls.

As per David Mosberger's request, splits into per-arch files (solves the
#include mess), and fixes my "was not an lvalue" bug.

Cosmetic change: x86_capability.  Makes it an unsigned long, and
removes the gratuitous & operators (it is already an array).  These
produce warnings when set_bit() etc. takes an unsigned long * instead
of a void *.

Originally from Rusty Russell

i810_rng: add support for other i8xx chipsets to the Random Number Generator module.
This is being done by adding the detection of the 82801BA(M) and 82801CA(M) I/O Controller Hub's.

- Eliminate the mate member of the ata_channel structure. The information
   provided by it is already present. This patch may have undesirable
   effects on the ns87415.c and trm290.c host chip drivers, but it's worth
   for structural reasons to have it.

- Kill unused code, which was "fixing" interrupt routing from ide-pci.c Don't
   pass any "mate" between the functions there.

- Don't define SUPPORT_VLB_SYNC unconditionally in ide-taskfile.c

- Apply Vojtech Pavliks fix for piix host-chip driver crashes.

- Add linux/types.h to ide-pnp.c.

- Apply latest sis5513 host chip driver patch from by Lionel Bouton by hand.

- Apply patch by Paul Macerras for power-mac.

- Try to make the ns87415 driver a bit more reentrant.

cleaned up the comments to put them in proper docbook format.

sanity checking and cleanup on device disconnect.
  
    - Splits apart usb_dec_dev_use(), for driver use, and
      usb_free_dev(), for hub/hcd use.  Both now have
      kerneldoc, and will BUG() if the refcount and the
      device tree get out of sync.  (Except for cleanup of
      root hub init errors, refcount must go to zero only
      at the instant disconnect processing completes.)
  
    - More usbcore-internal function declarations are
      now moved out of <linux/usb.h> into hcd.h
  
    - Driver-accessible refcounting is now inlined; minor
      code shrinkage, it's using atomic inc/dec instructions
      not function calls.

<note from greg k-h, there is still some work to be done with USB device
 reference counting, but this patch is a step in the right direction.>

This fixes some kerneldoc bugs for USB.  It catches up with
the recent rename, and includes a couple minor tweaks/fixes
I happened to notice.

- Documentation updates
- BKL removal (devfs doesn't need the BKL)
- Changed <devfs_rmdir> to allow later additions if not yet empty
- Added calls to <devfs_register_partitions> in drivers/block/blkpc.c
  <add_partition> and <del_partition>
- Bug fixes in unique number and devnum allocators.

This patch moves the generation of the asm interrupt entry stubs from
i8259.c to entry.S.  This allows it to be done with less code and
without needing duplicate definitions of SAVE_ALL, GET_CURRENT, etc.

It is a step on the road to removal of the arrays.
It also solves other things, like the fact that Linux
is unable to read the last sector of a disk or partition
with an odd number of sectors.

Unfortunately the proc filesystem has a limit on the number of dynamic
proc entries it can create. On large systems we can exhaust the default
(4096) very quickly. The following patch increases the default to
something more reasonable.

We forgot to include linux/init.h in fs/nfsd/nfsctl.c.

Since we do not set the task state to TASK_INTERRUPTIBLE, we busy loop.

On larger SMP this can actually result in a lockup due to the way
migration thread initalisation is done (nr_cpus threads are created
and they all busy loop until the scheduler evenly distributes them,
one on each cpu. With this rogue thread busy looping things can become
unbalanced and the migration threads never distribute themselves onto
all cpus).

include/linux/seq_file.h uses memcpy and struct semaphore and so should
include the relevant files.

renamed the bluetooth.c file to bluettty.c to help prevent user confusion
between this driver and the bluez bluetooth stack in the kernel.

This was originally created by David many months ago and posted to the
list, but not put into the kernel.

I modified the original patch to:
-patch against the 2.5.7 kernel
-use the 'real' interface number, not position (to do this I added 2
 methods in usb.c)

Here is an updated patch using kmalloc that removes the page limit
on bulk transfers in usbfs.  I've tested it and it seems to work OK.

(eg ppc64) where foo points to a function descriptor and .foo is
the address of the actual function.

optimisations on some architectures.

ppc64: remove local_flush_* functions, just define them directly
