Correct the logic error making it fail

| changes that I had in ide-scsi.c in the stock kernel's before
| Martin Dalecki's IDE tree was reverted and a few other changes.
| 
|         The principal change is that each ATAPI device is a Scsi_host
| (which reflects reality), instead of having one fake Scsi_Host with
| that appears to have all of the ATAPI devices on one bus regardless of
| actual hardware topology.  This way it is much easier for software to
| tell that, for example, a scsi copy command will not work between two
| ATAPI devices.  More importantly, hot plugging should theoretically
| work now, since Scsi_hosts are allocated and deallocated as ATAPI
| devices are added or removed. 
| 
|         This change eliminates the idescsi_drives[] array and the
| ide_driver_t.id field that was used to index it.
| 
|         The idescsi_scsi_t data structure is now allocated at
| the end of the struct Scsi_Host rather than being a separate
| memory allocation.  The calculation of various private pointers
| are changed slightly as a result.
| 
|         Other minor nits include making all global routines
| static and adding some missing error branches in
| init_idescsi_module.
| 
|         I've verified that I can at least read raw data
| from a DVD-ROM with with this change.
| 
|         When I unload this ide-scsi module, the stock ide-scsi module
| or the stock ide-cd modules in 2.5.56, I get what appears to be the
| same kernel bad memory reference, apparently due to some generic
| device device added to drivers/ide/ide.c.  It does not appear to
| be due to this patch.
| 
|         The patch is a net deletion of one line.

The perverse CHECK_CONDITION in include/scsi/scsi.h seems
to have struck again (see "Can't burn DVD under 2.5.59 with
ide-cd" thread on the linux kernel list). Most users of
CHECK_CONDITION found out to their surprise that it is
shifted 1 bit (right) from those values found in the
standards.

passed functional test.

	o Add some more DV diagnostic code
	o Fix bug that cause sequencer debug code to be
	  downloaded always.

Aic79xx Driver Update 1.3.0.RC2
	o Correct a bug that effectively limited DV to just ID 0.
	o Add some more DV diagnostic code
	o Misc code cleanups.

	Force an SDTR after a rejected WDTR if the syncrate is unkonwn.

  o Determine more conclusively that a BIOS has initialized the
    adapter before using "left over BIOS settings".
  o Adapt to upcoming removal of cmd->target/channel/lun/host in 2.5.X
  o Fix a memory leak on driver unload.
  o Enable the pci_parity command line option and default to pci parity
    error detection *disabled*.  There are just too many broken VIA
    chipsets out there.
  o Move more functionality into aiclib to share with the aic79xx driver.
  o Correct a few negotiation regressions.
  o Don't bother doing full DV on devices that only support async transfers.
    This should fix a few more of the reported problems with DV.

Aic79xx Driver Update
  o Add abort and bus device reset handlers.
  o Fix a memory leak on driver unload.
  o Adapt to upcoming removal of cmd->target/channel/lun/host in 2.5.X.
  o Correct a few negotiation regressions.

	Enable abort and bus device reset handlers for both legacy
	and packetized connections.

	Don't bother with DV if the device can only do async

__virt_to_bus/__bus_to_virt depended on INTEGRATOR_HDR0_SDRAM_BASE
Unfortunately, this is defined in arch-integrator/platform.h, and
we really don't want to include it in memory.h.

We instead use BUS_OFFSET, which will eventually depend on the CPU
number in the system.

Only default BLK_DEV_IDEDMA on BLK_DEV_IDEDMA_ICS if ARCH_ACORN is
set, not if ARM is set.  There are PCI ARM systems out there!

Ensure that we clean up properly after initialisation error,
releasing all claimed resources in an orderly manner and
returning the correct error code.

Add cfbfillrect / cfbcopyarea / cfbimgblt objects for SA1100fb.
Remove redundant "pm" member.

Found a buglet in the marvel code -- doesn't change the number of IRQS
just the logic to get there.. This applies on top of the other marvel
code.

Patch from Erich Focht

This adds a hook to rebalance globally across nodes every NODE_BALANCE_RATE
iterations of the rebalancer. This allows us to easily tune on an architecture
specific basis how often we wish to rebalance - machines with higher NUMA
ratios (more expensive off-node access) will want to do this less often.
It's currently set to 100 for NUMA-Q and 10 for other machines. If the
imbalance between nodes is > 125%, we'll rebalance them. The hook for this
is added to the NUMA definition of cpus_to_balance, so again, no impact
on non-NUMA machines.

Patch from Michael Hohnbaum

This adds a hook, sched_balance_exec(), to the exec code, to make it
place the exec'ed task on the least loaded queue. We have less state
to move at exec time than fork time, so this is the cheapest point
to cross-node migrate. Experience in Dynix/PTX and testing on Linux
has confirmed that this is the cheapest time to move tasks between nodes.

It also macro-wraps changes to nr_running, to allow us to keep track of
per-node nr_running as well. Again, no impact on non-NUMA machines.

Patch from Martin J. Bligh

This adds a small hook to the find_busiest_queue routine to allow us to
specify a mask of which CPUs to search over. In the NUMA case, it will
only balance inside the node (much cheaper to search, and stops tasks
from bouncing across nodes, which is very costly). The cpus_to_balance
routine is conditionally defined to ensure no impact to non-NUMA machines.

This is a tiny NUMA scheduler, but it needs the assistance of the second
and third patches in order to spread tasks across nodes.

Another left-over from ancient module code, it was supposed to return
non-zero if the module has a use count, but currently it always
evaluates to 0.

There are a few users of different types:
(1)  ioctl that perform a while(MOD_IN_USE) MOD_DEC_USE_COUNT loop.
     Just rip them out, we now have forced module unloading.
(2)  printk's that moan if the use-count in not zero in the exitfunc.
     Just rip them out, this can't happen.
(3)  if(MOD_IN_USE) MOD_DEC_USE_COUNT constructs in ->close of a few
     serial drivers.  Just remove the conditional, we did a
     MOD_INC_USE_COUNT in ->open.
(4)  This one is interesting:  drivers/sbus/char/display7seg.c uses
     the module use count to track openers.  Replace this with an
     atomic_t.

In addition remove tons of stale comments in network driver that aren't
understandable for anyone who doesn't know ancient Linux module semantics.

x86-64 updates for 2.5.58. Changes only x86-64 specific files.

 - Rewrote module allocation. Lots of bugs fixed. Module loading
   should work now again.
 - Kconfig help fixes from Randy Dunlap
 - Makefile cleanups from Pavel Machek and Sam Ravnborg
 - Assembly cleanups from Pavel
 - defconfig update
 - Better strlen_user/strnlen_user
 - Merge with i386: new ptrace commands, 32bit vsyscall signal trampolines
		new deactivate_mm, add asm/bug.h
 - Make sure initramfs is freed after booting (thanks to Kai for the hint)
 - User per cpu data for profile counters (Ravikiran Thirumalai)
 - 32bit compat_* updates from Stephen Rothwell
 - Fix race in context switch. The exception handler for bogus segment
   loads in __switch_to needs to keep interrupts disabled, otherwise an
   interrupt can deadlock on scheduler locks.  Also make sure they don't
   printk or set oops_in_progress during printk because printk does a
   wake_up too.
 - Disable 64bit GS base changes for processes.  I cannot get it to work
   reliably.
 - Clear IOPL on kernel entry

From Jeff.Wiedemeier@hp.com:

Add platform-specific callin for SMP.

From Jeff.Wiedemeier@hp.com:

- Only create smp_affinity /proc nodes if a set_affinity handler
  is provided.
- Limit the number of irq nodes that will be created in /proc
  to avoid overfilling the /proc inode space.
