We can bomb out early, so don't poke any registers just in case.

	Sigh...  Build/fix bugs/rediff/send the old diff story...
Sorry - just have noticed that ;-/

With CONFIG_REGPARM=y, syscalls must be declared asmlinkage or else
calling them will fail.

This fix adds a few missing declarations for sys_fadvise64_64() and
sys_remap_file_pages().

This fixes the SCSI layer to handle non-sector-aligned requests from
SG_IO (and potentially anything else producing these requests) that
could stall the machine and cause all sorts of funnies depending on the
low level driver used.

This makes the default alignment requirements be 512 bytes for SCSI,
the way it used to be.

Jens will fix the SCSI layer problems, but low-level drivers might have
other restrictions on alignment.

CONFIG_IRQBALANCE only affects arch/i386/kernel/io_apic.c, so you should
only see it as an option if you actually have one of those.  This patch
makes IRQBALANCE depend on X86_IO_APIC.

	... yes, Virginia, some perverts *do* tweak widely shared
method tables and do that in very sensitive spots, at that...

This fixes the ppc64 /proc/cpuinfo oops introduced with the lmb
cleanups.

We are trying to slowly phase out the LMB stuff (it mostly duplicates
functionality of bootmem...), this part got overlooked.

There were a number of bugs in our cmd_line handling:

- We were looking at cmd_line after it had been tokenised. Use saved_command
  line instead
- Use strlcpy instead of memcpy/explicit NULL set.
- Remove magic numbers in iseries cmd_line parsing

UP compile fixes.

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.

From: Anton Blanchard <anton@samba.org>

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

From: Anton Blanchard <anton@samba.org>

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.
