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.

- 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.

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

ppc64: remove local_flush_* functions, just define them directly

ide-dma incorrectly only clears high memory support if the verbose dma
disabling is called, it should clear it for the non-verbose too.

Hi Linus,

Oops, SMP non-ACPI doesn't compile with the previous ACPI update. This
fixes that.
