M68k build fixes, caused by kbuild changes in 2.5.41:
  - 68040 Floating Point and 68060 Integer and Floating Point Support Packages:
    use cpp includes instead of gas includes
  - Add `$(obj)' and `$(src)' where necessary to fix building of generated
    header files

2.5.44 linker file updates for m68k:
  - .*.init got renamed to .init.* to allow -ffunction-sections
  - discard .exit* sections like most other ports do

Convert core Amiga code to new local_irq*() framework

Re-add lost forward declarations of arch-specific *_mksound() routines, we need
them for the m68kspkr driver.

  - Avoid too much inline assembly in __xchg
  - Add irqs_disabled(), which appeared in 2.5.34
  - Add missing implementation for in_atomic() (introduced in 2.5.35)

M68k IDE lock fixes:

Misc compile fixes for m68k:
  - missing and superfluous casts
  - unused code

Fix dyslexia in Amiga keyboard driver

M68k epoll: add POLLREMOVE

M68k: revive csum_partial_copy_nocheck() after csum_partial_copy() was removed
in 2.5.44 (from Roman Zippel)

Since m68kspkr can be a module, we need to initialize mach_beep() for a modular
m68kspkr as well.

C99 designated initializers for include/asm-m68k/thread_info.h (from Art Haas

This means:
  1/ We don't need an order-4 allocation for each nfsd that starts
  2/ We don't need an order-4 allocation in skb_linearize when
     we receive a 32K write request
  3/ It will be easier to incorporate the zero-copy read changes

The pages are handed around using an xdr_buf (instead of svc_buf)
much like the NFS client so future crypto code can use the same
data structure for both client and server.

The code assumes that most requests and replies fit in a single page.
The exceptions are assumed to have some largish 'data' bit, and the
rest must fit in a single page.
The 'data' bits are file data, readdir data, and symlinks.
There must be only one 'data' bit per request.
This is all fine for nfs/nlm.

This isn't complete:
  1/ NFSv4 hasn't been converted yet (it won't compile)
  2/ NFSv3 allows symlinks upto 4096, but the code will only support
     upto about 3800 at the moment
  3/ readdir responses are limited to about 3800.

but I thought that patch was big enough, and the rest can come
later.


This patch introduces vfs_readv and vfs_writev as parallels to
vfs_read and vfs_write.  This means there is a fair bit of
duplication in read_write.c that should probably be tidied up...

nfsd_readdir - the common readdir code for all version of nfsd,
contains a number of version-specific things with appropriate checks,
and also does some xdr-encoding which rightly belongs elsewhere.

This patch simplifies nfsd_readdir to do just the core stuff, and moves
the version specifics into version specific files, and the xdr encoding
into xdr encoding files.

I forgot to add '1' for the record-length header in RPC/TCP.

Currently if the kmalloc in exports_open fails,
the seq_file isn't seq_released.

We now do the kmalloc first, and make sure to kfree
if seq_open fails.

The 'unexport everything' that happens when the
last nfsd thread dies was shuting down too much -
things that should only be shut down on module unload.

There is one remaining instance of CONFIG_MULTIQUAD in the kernel source.

Fix it to use the proper CONFIG_X86_NUMAQ instead.

Define an interface for interpreting and updating superblocks
so we can more easily define new formats.

With this patch, (almost) all superblock layout information is
locating in a small set of routines dedicated to superblock
handling.  This will allow us to provide a similar set for
a different format.

The two exceptions are:
 1/ autostart_array where the devices listed in the superblock
    are searched for.
 2/ raid5 'knows' the maximum number of devices for
     compute_parity.

These will be addressed in a later patch.

A few updates for x86-64 in 2.5.44. Some of the bugs fixed were serious.

- Don't count ACPI mappings in end_pfn. This shrinks mem_map a lot
  on many setups.
- Fix mem= option. Remove custom mapping support.
- Revert per_cpu implementation to the generic version. The optimized one
  that used %gs directly triggered too many toolkit problems and was an
  constant source of bugs.
- Make sure pgd_offset_k works correctly for vmalloc mappings. This makes
  modules work again properly.
- Export pci dma symbols
- Export other symbols to make more modules work
- Don't drop physical address bits >32bit on iommu free.
- Add more prototypes to fix warnings
- Resync pci subsystem with i386
- Fix pci dma kernel option parsing.
- Do PCI peer bus scanning after ACPI in case it missed some busses
  (that's a workaround - 2.5 ACPI seems to have some problems here that
  I need to investigate more closely)
- Remove the .eh_frame on linking. This saves several hundred KB in the
  bzImage
- Fix MTRR initialization. It works properly now on SMP again.
- Fix kernel option parsing, it was broken by section name changes in
  init.h
- A few other cleanups and fixes.
- Fix nonatomic warning in ioport.c
