ATAPI multi-lun support has been broken for a long time.

It used to be that "(drive->id->last_id & 0x7) + 1" was used as
shost->max_lun and the "hdXlun=" kernel parameter could be used to
override this value.

However it was far from optimal:
- people played with "hdXlun=" and then complained about multiple instances
  of the same device (most ATAPI drives respond to each LUN)
- probably some devices return 7 not 0 in id->last_id (=> 7 x same device)

This patch from Willem Riede <wrlk@riede.org> fixes it w/o need
for "hdXlun=" option.  It was tested by Willem on ATAPI PD/CD drive.

wait_task_inactive is now only used in two non-time-critical places: the
ptrace code to guarantee a schedule and kthread_bind so we can change
the thread CPU.  Unfortunately with preempt, the code as stands has a
race: we might return because the thread is preempted, not because it
actually reached schedule().  The ptrace code (probably) doesn't care,
but the kthread code does.

This patch simplifies the (now over-optimized) code, and does a yield()
for the preemption case.

Simple obvious patch so that all calls to blkpg from the non-native
environment don't get -EINVAL

RX skbs are always considered maximally sized, until actual reception
of the RX frame occurs.  So, update this driver to always map and
unmap a maximally sized skb.  This fixes this driver on several
non-x86 platforms.

Verified to not break anything on x86 either.

This saves some memory and is easier to understand what is happening.

We also need the following patch to build the generic_defconfig

This patch is from Iomega, and it allows random write opens of CDROM's
that support the feature.

From: Anton Blanchard <anton@samba.org>

We have some versions of firmware out there that have huge OF properties.
So huge that we end up overwriting our initrd.

Place a 1MB limit and warn bitterly if its over this.  Also fix a use of
package-to-path where the variable was 64bytes but we would pass in a
length of 255.

ppc64 defconfig update

This patch fixes the sleep in spinlock hvc bug in hvc_write().

The code is a little longer, but protects against large amounts of memory
being kmalloc()ed by userspace, and minimises calls to copy_from_user().

Clean up xmon backtrace code, it was doing all manner of scary things.

From: Anton Blanchard <anton@samba.org>

Cleanup ppc64 procfs code:

- Use initcalls everywhere. This allowed us to remove the iseries proc
  callback interface.
- Kill proc_pmc.c. Most of it wasnt used (and we are planning to export the
  PMCs via sysfs). The few things left were iseries specific so they
  got moved into iSeries_proc.c.
- Kill pmc.c. We dont use those statistics and the ones that are left
  can be gained via PMCs.
- Create /proc/iSeries and /proc/ppc64 very early. This means we no
  longer have to call proc_ppc64_init in all the drivers, we can
  assume its there.
- Fix some error return cases in rtas-proc.c and rtas-flash
- Dont even try some pseries specific drivers on pmac.

Dont enable interrupts during interrupt processing on iseries

From: Jake Moilanen <moilanen@austin.ibm.com>

In xics_get_irq(), for a real-to-virt irq lookup, go down the
slowpath by looking through the entire virt_irq_to_real_map array
if take a miss on the radix tree.  This is possible, when an
interrupt is taken before the driver has called request_irq() (eg IDE).

Add some functions to make vio.h consistant with pci_dma.h and dma_mapping.h

From: Anton Blanchard <anton@samba.org>

- Merge some whitespace differences with the ameslab tree
- We check for CPU_MASK_ALL in xics to send irqs to all cpus.
  In some cases CPU_MASK_ALL is smaller than the cpumask (eg
  NR_CPUS == 32 and cpumask is a long), so we mask it here to
  be consistent.

From: Linas Vepstas <linas@austin.ibm.com>

This patch fixes multiple EEH-related bugs:

 - Fixes the eeh_check_failure() usage in an interrupt context.
   This routine is now safe to use in an interrupt. The fix was to
   build a cache of IO addresses and check that, instead of using
   the pci routines.
 - Merges in Olof Johansson's sizeof patch when checking for failure
 - Adds EEH tests to array/string reads
 - Fixes bugs with address resolution (some i/o addresses were handled
   incorrectly, resulting in EEH errors slipping by undetected.)
 - Adds EEH support to the PCI Hotplug system (so that devices that
   get added/removed get properly registered with the EEH subsystem.)
 - Fixes improper use of /proc filesystem.
 - Adds some misc statistics.

While merging Linas' patch I also converted the proc usage to
seq_single, used per cpu variables for the stats and removed the
eeh-force-off option.

From: Linda Xie <lxiep@us.ibm.com>

The changes in this patch are for multifunction cards insertions/removals
and  bug fixes:

1. fix up new nodes' linux_phandle field.
2. new nodes' phb, devfn(and so on) need to be fixed even the nodes don't
	have "interrupts".
3. change of_remove_node to non-recurisve func. The recursions will be done
	by the caller.
4. add a new function -- of_finish_dynamic_node_interrupts()
