This brain fart is left over from some cleanup of these functions a _long_ 
time ago. We need to dput() the dentry, since we have an implicit count of
one left over from the create function.

Instead, we were dput() on the directory that it was in, which we didn't 
have a matching dget() for.

MODULE and CONFIG_HOTPLUG cpp symbols.  Merge 2.4's definition to
make it so.

- rename at_addr to atalk_addr, netrange to atalk_netrange
- use kerneldoc style comments for some structs and functions
- move the IP over DDP handling code out of atalk_rcv into handle_ip_over_ddp,
  that is optimized out when this feature was not selected by the user
- move the routing handling code out of atalk_rcv into atalk_route_packets
- create ddp_hdr and aarp_hdr inline functions to access those protocol headers
  on the skb
- lots of CodingStyle cleanups

This patch removes an artifact of code left over from the 2.0 days when
the kernel didn't use flat segments.

The preceding memcpy() already takes care of the NULL ptr mapping.

Unfortunately, someone changed the inb and friends definitions and
broke ARM.  This patch allows ARM to build NE2000 based drivers
again.

The following patch adds support for CONFIG_GENERIC_ISA_DMA, which went
into the 2.4-ac kernel series prior to 2.5 happening.

The following patch allows architectures to decide whether they want
the generic ISA DMA functionality provided by kernel/dma.c and other
supporting files.

In addition, we move the procfs "/proc/dma" support code out of fs/proc
into kernel/dma.c, and adapt it to use the new seq_file code.

The following patch is required so that munmap(0x8000, *) does not cause
ARM kernels to crash.  The problem is that the machine vectors are at
virtual address 0.  Unfortunately, when free_pgtables() is called, it
clears first level page tables starting at 0 in this case, and takes
out the machine vectors.  This then results in an unrecoverable hang.

We already have FIRST_USER_PGD_NR to define the first entry in the pgd
which may be cleared, so we use this to clamp "start_index"
appropriately.  The following patch does this.  Tested on ARM.

Bitops are used with on the timer_alive variable.  Therefore, timer_alive
needs to be "unsigned long" not "int".

Trivial patch; removes cruft that got left over from the TLB shootdown
changes.  "dir" is never used in zap_page_range
