- support new 2.5 irqreturn_t
- s/usec_delay/udelay/
- remove two stored-but-never-used members of struct ixgb_hw
- read PCI vendor/device ids from struct pci_dev, not h/w
- remove some unused wrappers from ixgb_osdep.h

* Wrap TSO support with NETIF_F_TSO to keep same driver
  source between 2.4 and 2.5.

100% irqreturn_t cleanups

	hd98 had missed a lot of required block device patches (e.g.
it used BLK_DEFAULT_QUEUE and that had been gone for ~ half a year).
Reproduced the changes done to hd.c.

	Somewhat cleaned up, sanitized the module init/exit code (BTW,
built-in case was b0rken for quite a while - somebody forgot to add
initcall there; converted the bugger to module_init/module_exit)

	New helper - bdget_disk(gendisk, partition)
	invalidate_device() replaced with invalidate_partition(disk, part)

	Obvious cleanup of the code in init_blkmtd().  Killed code duplication,
replaced opening underlying block device manually with use of appropriate
helpers.

	New helper - open_by_devnum().  Opens block_device by device number;
for use in situations when we really have nothing better than dev_t (i.e.
had received it from stupid userland API).

	A couple of helpers - simple_pin_fs() and simple_release_fs().
My fault - that code should've been put into libfs.c from the very
beginning.  As it is, it got copied all over the place (binfmt_misc,
capifs, usbfs, usbdevfs, rpc_pipefs).
	Taken to libfs.c and cleaned up.

	New libfs.c helper - simple_fill_super().  Abstracted from
nfsd/nfsctl.c, couple of filesystems converted to it (nfsctl, binfmt_misc).

	Function takes an array of triples (name, file_operations, mode),
superblock and value for its ->s_magic.  It acts as fill_super() - populates
superblock or fails.  We get a ramfs-style flat tree - root directory and
a bunch of files in it.

	That animal allows to put together a simple filesystem without
touching any directory-related stuff - now it's as easy as implementing
file_operations for files you want to have and telling what to call them.

set_pgd implies that we're setting a pgd entry.  We aren't; we're
switching the MMU page table pointer.  Call it switch_mm instead.

check_bugs() has never been used to detect buggy ARM CPUs.  Therefore
is no point in passing it to the per-cpu support code.

This is the new API; we now have methods for handling DMA which are
separate from those handling the TLB consistency issues, which are
in turn separate from the methods handling the cache coherency
issues.

Implementations are, however, free to alias these methods internally.

This starts to move the ARM cache handling interface towards a
purpose-defined rather than functionality-defined interface.
This is necessary so we are able to support a wide range of ARM
CPUs.

The common case is building a kernel for one CPU type, and we are
able to allow GCC to optimise any the PMD entry cache handling
assembly which will never be used.

fault-common.c included unnecessary headers.
mach-integrator.c needed list.h included.

Prevent all gcc's from assuming that assembly within asm() may be
conditional.

We need to parse the command line arguments not only for the memory
parameters, but also CPU cache policies.  Rather than extending the
early parsing in arch/arm/kernel/setup.c, we make this a generic
feature.  The parameters and their parsing function can now be
placed along side the code which makes use of the parsed information.

Saner selection of architecture build flags (for Xscale)
Make asm-offsets.s depend on the selected platform

Patch from Alexander Schulz

I cannot compile the file cyber2000fb.c because of an undifined 
reference to machine_is_netwinder(). This patch makes it compile again.

[trivia] Remove duplicated defines of PRD_BYTES and PRD_ENTRIES.

Fix compilation of CONFIG_IDE_TASKFILE_IO, but don't expose this config
option yet.

Fix handling of read/write DMA in do_rw_taskfile(),
it was broken because default return value is ide_stopped.
