Can you guess what my laptop has in it?

There's tons of mis-use of PCI memory-mapped IO that is used
as if it was regular memory. That fails disastrously on a number
of architectures, and it doesn't help that it just happens to
work on regular x86 boxes.

This makes makes us do much stricter type-checking. Some of it
visible to the regular compiler, but the bulk of it is for sparse.

Make the actual use of hwif->data_phase.

Use it for taskfile requests (only PIO/DMA for now) for storing
ide_task_t->data_phase of the active command.

Also add some missing task->data_phase assignments.

Affected chipsets support LBA48 but not LBA48 DMA.
Just use DMA for area < 137GB and revert to PIO for > 137GB one.
Also disallow transfers > 256 sectors for better performance.

tmp_hwif should not be kmalloc()ed in ide_unregister().
If the kmalloc fails, there is no possible error recovery.
This patch makes tmp_hwif static, protected by ide_cfg_sem.

The time interpolator scalability enhancement patch broke the time
interpolator integration for hpet on IA64.  Here is the fix.

The recent sungem NAPI change introduced a bug: dev_kfree_skb() is
called within a softirq context, thus triggers all sort of WARN_ON's
later on down the stack.

This patch changes it to dev_kfree_skb_any().

The recent fbdev changes broke something quite fundamental on ppc, which
is the way offb works. It's a "fallback" driver that is to be used when
no other driver picked up the video, or when "forced" via the video=ofonly
command line option.

The recent changes completely broke that (which is a pretty important
behaviour on ppc since we still have some models regulary with video
cards that don't work properly with the kernel drivers, like some nVidias
or some older stuffs).

This patch moves offb to the end of the Makefile, so at least the behaviour
of taking over as a "fallback" is restored (the current kernel will have
offb take control of the framebuffer before any fbdev has a chance to do
it, which breaks everything).

Apparently, the entire support for "video=ofonly" was removed though,
that NEEDS to be restored in some way, though i'm not yet sure what is
the best path to that yet, I have to look more deeply at the new code.

 - create in_lock_functions() to match in_sched_functions(). Export it
   for use in oprofile.
 - use char __lock_text_start[] instead of long __lock_text_start when
   declaring linker symbols. Rusty fixed a number of these a while ago
   based on advice from rth.
 - Move __preempt_*_lock into kernel/spinlock.c and make it inline. This
   means locks are only one deep.
 - Make in_sched_functions() check in_lock_functions()

Andries made a declaration static, and this clashed with Al who
changed it for byteorder annotation. Fix it all up.

That one was slightly messier than ext2 - several data structures had
been used both in little-endian (on-disk) and host-endian (in-core)
situations.  They had to be split, the rest was trivial annotations. 

Gets UDF sparse-clean with -Wbitwise.  Note that here we just annotate -
bug fixes from the original version of that patch had already been
merged.

AFFS partially annotated - some fields of on-disk structures are never
used and while I'm reasonably sure that they ought to be big-endian, I'd
rather leave them alone for now; annotating them won't change the amount
of noise since nothing in the kernel ever accesses them.
