Restore the old cpu names in /proc/cpuinfo, some applications parse this
field.

Some trivial oops cleanups.

Set node 0 online, otherwise the recent cpu/memory topology stuff will oops
on a non NUMA machine.

set err to -ENODEV when a new node doesn't have "interrupt" property.

From: Anton Blanchard <anton@samba.org>

__get_SP used to be a function call which meant we allocated a stack
frame before calling it. This meant the SP it returned was one frame
below the current function. Lets call that bogusSP (and the real one
SP).

The new dump_stack was being tail call optimised so it remained one
frame above bogusSP. dump_stack would then store below SP (as the ABI
allows us to) and would stomp over the back link that bogusSP pointed
to (__get_SP had set the back link up so it worked sometimes, just not
all the time).

Fix this by just making __get_SP an inline that returns the current SP.

I think Ben introduced this new file and iSeries doesn't need it.

Another decent optimisation found in the ia64 port, dont take the irq
descriptor lock or do the note_interrupt stuff on PER_CPU irqs (ie IPIs).

Clean up per cpu usage in segment table code.

Make a number of segment table functions static.
Clean up one duplicated slbia.

Add cpus and NUMA memory nodes to sysfs. Also add cpu physical id.

From: Anton Blanchard <anton@samba.org>

The might_sleep infrastructure doesnt like our get_users in the backtrace
code, we often end up with might_sleep warnings inside might_sleep warnings.

Instead just be careful about pointers before dereferencing them.

Also remove the hack where we only printed the bottom 32bits of the WCHAN
value.

From: Anton Blanchard <anton@samba.org>

This adds stack overflow debugging much like x86. Its pretty agressive
and checks if > 8kB out of 16kB of stack is used.

This cleans up the rtasd logic, and also makes it hotplug CPU safe.

From: Anton Blanchard <anton@samba.org>

smp_message_pass has a few args that are never used. Remove em.
Also add memory missing memory barrier in smp_call_function_interrupt.

From: Rusty Russell <rusty@rustcorp.com.au>

1) Check for cpuids >= NR_CPUS in prom_hold_cpus: we previously
   overflowed arrays when this happened, and checking it here ensures
   that it doesn't happen elsewhere.  Still move processors to
   secondary_hold (out of OF), but we won't release them.

2) smp_iSeries_message_pass and smp_xics_message_pass don't need to
   iterate if given a specific CPU: cleanup and fix.

3) kick_cpu variants don't need to check cpu range (caller is screwed
   anyway if this happened): replaced with BUG_ON for now.

4) smp_openpic_probe and smp_xics_probe can use cpus_weight(): it's
   faster and simpler.

5) User for_each_cpu/for_each_online_cpu as appropriate.

fix warning and compile error without CONFIG_SMP

From: Dave Boutcher <sleddog@us.ibm.com>

fix naming collision with asm-ppc64/vio.h. The define would be set there and
this file would not get pulled in.

Fix for valid nvram rtas tokens.

Add log_rtas_error(), to be called in the event that a rtas call
returns a hardware error (-1) so we can log additional information
about the hardware error.

Add call to rtas to retrieve slot-error-detail information and

Remove duplicate pcibios_scan_all_fns definition

From: Anton Blanchard <anton@samba.org>

This appeared in the ia64 port and sounds like a good idea. Potentially
avoid an atomic operation in switch_mm.

From: Anton Blanchard <anton@samba.org>

- remove LMB_MEMORY_AREA, LMB_IO_AREA, we only allocate/reserve memory
  areas now
- remove lmb_property->type, lmb_region->iosize, lmb_region->lcd_size,
  no longer used
- bump number of regions to 128, we'll hit this limit sooner or later
  with our big boxes (if we have more than 64 PCI host bridges the
  reserved array will fill up for example)
- make all the lmb stuff __init
- no need to explicitly zero struct lmb lmb now we zero the BSS early
- we had two functions to dump the lmb array, kill one of them
- move the inline functions into lmb.c, they are only ever called from
  there

From: Anton Blanchard <anton@samba.org>

There is a prototype for dump_regs on ppc32 and ppc64 but its never
defined.  Remove it since it conflicts with something in
drivers/atm/horizon.c.

Also clean up ppc64 system.h a bit to match the ppc32 version.

This sounds like a good moment to come with this patch.

This is essentially a five-year-old patch by Bruno Haible.  It
introduces utf8 mode, and the effect it has on erasing input characters.

(Side note - without stty support, this is not very useful, but now
the infrastructure is in place)

	We never use CONFIG_BINFTM_ELF and CONFIG_BINFMT_ELF_MODULE
anywhere in the source (they are used in makefiles, obviously).
32bit-emulation binfmt_elf_... in arch/* still define those guys
even though it hadn't been needed for years.

	Junk removed.

PS: BTW, CONFIG_BINFMT_ELF32 _is_ used in several places in arch/mips and it
looks like they really want
#if defined(CONFIG_BINFMT_ELF32) || defined(CONFIG_BINFMT_ELF32_MODULE)
in these ifdefs, but that's a separate story...

I was modifying mkfs.xfs to use O_EXCL for 2.6, and hit a snag.
It seems that once I've opened a block dev with O_EXCL I can no
longer issue the BLKBSZSET ioctl to it.

Making this change, the ioctl succeeds cos the original filp bdev owner
from open now matches with the owner in the ioctl call.
