This patch makes the following needlessly global code static:

- arch_reinit_sched_domains()
- struct attr_sched_mc_power_savings
- struct attr_sched_smt_power_savings

The Averatec 2370 and some other Turion laptop BIOS seems to program the
ENABLE_C1E MSR inconsistently between cores. This confuses the lapic
use heuristics because when C1E is enabled anywhere it seems to affect
the complete chip.

Use a global flag instead of a per cpu flag to handle this.
If any CPU has C1E enabled disabled lapic use.

Thanks to Cal Peake for debugging.

Commit 19d36ccdc34f5ed444f8a6af0cbfdb6790eb1177 "x86: Fix alternatives
and kprobes to remap write-protected kernel text" uses code which is
being patched for patching.

In particular, paravirt_ops does patching in two stages: first it
calls paravirt_ops.patch, then it fills any remaining instructions
with nop_out().  nop_out calls text_poke() which calls
lookup_address() which calls pgd_val() (aka paravirt_ops.pgd_val):
that call site is one of the places we patch.

If we always do patching as one single call to text_poke(), we only
need make sure we're not patching the memcpy in text_poke itself.
This means the prototype to paravirt_ops.patch needs to change, to
marshal the new code into a buffer rather than patching in place as it
does now.  It also means all patching goes through text_poke(), which
is known to be safe (apply_alternatives is also changed to make a
single patch).

gcc currently doesn't support attributes on types, so we can't use it
function pointers.  This avoids some warnings on a gcc 4.3 build.

There are some parts of include/asm-generic/pgtable.h that are relevant to
the non-mmu architectures.  To make it easier to include this from them I
would like to ifdef the relevant parts.

Without this there is a handful of functions that are referenced in here
that are not defined on many non-mmu architectures.  They could be defined
out of course, as an alternative approach.

This patch finishes the i386 and x86-64 ->sysdata conversion and hopefully
also fixes Riku's and Andy's observed bugs.  It is based on Yinghai Lu's
and Andy Whitcroft's patches (thanks!) with some changes:

- introduce pci_scan_bus_with_sysdata() and use it instead of
  pci_scan_bus() where appropriate. pci_scan_bus_with_sysdata() will
  allocate the sysdata structure and then call pci_scan_bus().
- always allocate pci_sysdata dynamically. The whole point of this
  sysdata work is to make it easy to do root-bus specific things
  (e.g., support PCI domains and IOMMU's). I dislike using a default
  struct pci_sysdata in some places and a dynamically allocated
  pci_sysdata elsewhere - the potential for someone indavertantly
  changing the default structure is too high.
- this patch only makes the minimal changes necessary, i.e., the NUMA node is
  always initialized to -1. Patches to do the right thing with regards
  to the NUMA node can build on top of this (either add a 'node'
  parameter to pci_scan_bus_with_sysdata() or just update the node
  when it becomes known).

The patch was compile tested with various configurations (e.g., NUMAQ,
VISWS) and run-time tested on i386 and x86-64.  Unfortunately none of my
machines exhibited the bugs so caveat emptor.

Andy, could you please see if this fixes the NUMA issues you've seen?
Riku, does this fix "pci=noacpi" on your laptop?
