RIP.  It's not used anymore, so we kill assignments to it and the
field itself.  That was the last serious use of kdev_t in block drivers.

	* in floppy drivers and ps2esdi - replaced with use of ->rq_disk;
floppy drivers already have information about "type" part of device number
- they had stored that information in floppy_open(), so all we need is a
"which drive" part.  And that is available from ->rq_disk.
	* DAC960: changed ->private_data initialization - instead of pointing
it to controller (which we already have as disk->queue.queuedata) we simply
store a disk number in there.  That had simplified ->revalidate_disk() and
allowed to kill the use of ->rq_dev in request handler.

	* killed the uses of ->rq_dev in printks - several drivers.

	* uses in ll_rw_blk.c and elevator.c eliminated - ->rq_disk has
everything we need.

	* eliminated, since we actually wanted the name, not device number
(BTW, that had also killed calculation of name that used to duplicate sd.c
one)

	_Now_ we can clean the scsi_get_request_dev() up.  Indeed, for
any SCSI request we either have ->rq_dev == NODEV and ->rq_disk == NULL
or ->rq_disk->private_data points to address of template in question.
IOW, scsi_get_request_dev() becomes simply
{
	struct gendisk *p = req->rq_disk;
	return p ? *(struct Scsi_Device_Template **)p->private_data : NULL;
}
and that allows to kill ->max_major, ->min_major and ->major in
Scsi_Device_Template, along with the last non-trivial use of ->rq_dev.

	Ditto for sg.c

	Ditto for sd.c

	Ditto for sr.c

	Ditto for st.c

	Next 5 chunks prepare cleanup of scsi_get_request_dev().  Namely,
scsi_disk/scsi_cd/... get a new field - pointer to Scsi_Device_Template.
It is initialized with address of that driver's template.  sr.c and sd.c
have disk->private_data pointing to that field (instead of pointing to
entire structure).  osst.c, st.c and sg.c get gendisk - allocated, but
not registered (obviously) with ->private_name set in the same way.  When
they set ->rq_dev, they also set ->rq_disk.
	This chunk does it for osst.c

	->open() of st and osst sets file->private_data to Scsi_Tape in
question, other methods use it (same as in sg.c)

	* new inlined helper: tape_name(tape)
	* most of TAPE_NR() uses replaced with that animal
("st%d ...", TAPE_NR(STp), ... -> "%s ...", tape_name(STp), ... )

	* new inlined helper: tape_name(tape)
	* most of TAPE_NR() uses replaced with that animal
("osst%d ...", TAPE_NR(STp), ... -> "%s ...", tape_name(STp), ... )

- isapnp: asm/io.h is needed for inb() etc.;
- sync up with 2.5.44 vmlinux.lds changes.

OK, that's my f*ckup in rd.c (not on initrd path, actually) + couple of
f*ckups from Pat (mine: forgot to bump ->bd_count in rd_open(), Pat's:
dropped reference to gendisk on del_gendisk(), resulting in use of
kfree'd object + tried to remove a symlink that didn't exit).

This fixes these.  It also changes order of blkdev_put()/del_gendisk()
in initrd_release() - better safe than sorry.

It got initrd working on my boxen...

Dear David,

please find attached two patches for the latest 2.5.44-ia64. They fix
some problems and simplify things a bit.

remove_nodeid-2.5.44.patch:
This comes from Kimi. In 2.5.44 we suddenly had two definitions for
numa_node_id(), one was IA64 specific (local_cpu_data->nodeid) while
the other one is now platform independent:
__cpu_to_node(smp_processor_id()). After some discussions we decided
to remove the nodeid from the local_cpu_data and keep the definition of
all other platforms. With using the cpu_to_node_map[] we are also
faster when doing multiple lookups, as all node ids come in a single
cache line (which is not bounced around, as it's content is only
read).


ia64_topology_fixup-2.5.44.patch:
I'm following here the latest fixup for i386 from Matthew Dobson. The
__node_to_cpu_mask() macro now accesses an array which is initialized
after the ACPI CPU discovery. It also simplifies
__node_to_first_cpu(). A compiler warning has been fixed, too.


Please apply these to your kernel tree.

The hyper-threading in /proc/cpuinfo patch introduced a compile warning
under UP.

Fixed thus.

This trivial patch causes the TLS to be cleared on execve (code is in
flush_thread).  This is necessary to avoid ESRCH errors when
set_thread_area is asked to choose a free TLS entry after several nested
execve's.

The LDT also has a similar problem, but it is less serious because the
LDT code doesn't scan for free entries.  I'll probably send a patch to
fix this too, unless there is something important relying on this
behavior.

As per comment:

  restoring APIC_LVTPC can trigger an apic error because the delivery
  mode and vector nr combination can be illegal. That's by design: on
  power on apic lvt contain a zero vector nr which are legal only for
  NMI delivery mode. So inhibit apic err before restoring lvtpc

We need to use u64 because the future 64-bit ports can theoretically
return the same value for two different dentries, as pointed out by
Ulrich Weigand.

The patch also changes return value of the syscall to give length of
data copied, needed for valgrind support (this bit is by Philippe Elie).

Note this is not a complete fix for mixed 32/64: userspace needs to
figure out the kernel pointer size when reading from the buffer. But
that's another fix...

NOTE! any oprofile users will need to upgrade after this goes in, and
the user-space equivalent is checked into CVS.  Sorry for the inconvenience

Companion to the previous patch: all the support needed for non-ia32
architectures.

Patch from Ravikiran G Thirumalai <kiran@in.ibm.com>

1. Break out disk stats from kernel_stat and move disk stat to blkdev.h

2. Group cpu stat in kernel_stat and make them "per_cpu" instead of
   the NR_CPUS array

3. Remove EXPORT_SYMBOL(kstat) from ksyms.c (as I noticed that no module is
   using kstat)
