Suravee Suthikulpanit 9e7f7231e4 x86/PCI: Clean up and mark early_root_info_init() as deprecated
early_root_info_init() is now deprecated in favor of info in ACPI.  Add a
note to that effect.  Also, clean up the code a bit.

There is no functional change.

Suravee Suthikulpanit 94d4bb5b13 x86/PCI: Work around AMD Fam15h BIOSes that fail to provide _PXM
The BIOS is supposed to provide ACPI _PXM methods for PCI host bridges if
it cares about platform topology.  But some BIOSes do not, so add Fam15h
to the list of CPUs for which we fall back to reading node numbers from the
hardware.

Note that pci_acpi_scan_root() warns about the BIOS bug if we use this
information because (1) the hardware node numbers are not necessarily
compatible with other logical node numbers from ACPI, and (2) the lack of
_PXM forces OS updates that would not otherwise be required.

Linus Torvalds 467a9e1633 CPU hotplug notifiers registration fixes for 3.15-rc1
The purpose of this single series of commits from Srivatsa S Bhat (with
 a small piece from Gautham R Shenoy) touching multiple subsystems that use
 CPU hotplug notifiers is to provide a way to register them that will not
 lead to deadlocks with CPU online/offline operations as described in the
 changelog of commit 93ae4f978c (CPU hotplug: Provide lockless versions
 of callback registration functions).
 
 The first three commits in the series introduce the API and document it
 and the rest simply goes through the users of CPU hotplug notifiers and
 converts them to using the new method.

Srivatsa S. Bhat 9f668f6661 x86, pci, amd-bus: Fix CPU hotplug callback registration
Subsystems that want to register CPU hotplug callbacks, as well as perform
initialization for the CPUs that are already online, often do it as shown
below:

	get_online_cpus();

	for_each_online_cpu(cpu)
		init_cpu(cpu);

	register_cpu_notifier(&foobar_cpu_notifier);

	put_online_cpus();

This is wrong, since it is prone to ABBA deadlocks involving the
cpu_add_remove_lock and the cpu_hotplug.lock (when running concurrently
with CPU hotplug operations).

Instead, the correct and race-free way of performing the callback
registration is:

	cpu_notifier_register_begin();

	for_each_online_cpu(cpu)
		init_cpu(cpu);

	/* Note the use of the double underscored version of the API */
	__register_cpu_notifier(&foobar_cpu_notifier);

	cpu_notifier_register_done();

Fix the amd-bus code in x86 by using this latter form of callback
registration.

Paul Gortmaker 148f9bb877 x86: delete __cpuinit usage from all x86 files
The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications.  For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.

After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out.  Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.

Note that some harmless section mismatch warnings may result, since
notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
are flagged as __cpuinit  -- so if we remove the __cpuinit from
arch specific callers, we will also get section mismatch warnings.
As an intermediate step, we intend to turn the linux/init.h cpuinit
content into no-ops as early as possible, since that will get rid
of these warnings.  In any case, they are temporary and harmless.

This removes all the arch/x86 uses of the __cpuinit macros from
all C files.  x86 only had the one __CPUINIT used in assembly files,
and it wasn't paired off with a .previous or a __FINIT, so we can
delete it directly w/o any corresponding additional change there.

Andreas Herrmann ca3671a833 x86/PCI: amd: Kill misleading message about enablement of IO access to PCI ECS]
Commit 24d9b70b8c (x86: Use PCI method
for enabling AMD extended config space before MSR method) added a
message when IO access to PCI ECS was enabled via access to the NB_CFG
PCI register.  This can lead to a bogus message like

[    0.365177] Extended Config Space enabled on 0 nodes

which is misleading because IO ECS access is subsequently enabled for
AMD CPUs (that support this) by modifying the corresponding NB_CFG
MSR.

Furthermore it's not "Extended Config Space" that is enabled by this
register setting. It's the IO access that is enabled for extended
configruation space.

IMHO the ambiguous message needs to be cancelled.

Jan Beulich 24d9b70b8c x86: Use PCI method for enabling AMD extended config space before MSR method
While both methods should work equivalently well for the native
case, the Xen Dom0 case can't reliably work with the MSR one,
since there's no guarantee that the virtual CPUs it has
available fully cover all necessary physical ones.

As per the suggestion of Robert Richter the patch only adds the
PCI method, but leaves the MSR one as a fallback to cover new
systems the PCI IDs of which may not have got added to the code
base yet.

The only change in v2 is the breaking out of the new CPI
initialization method into a separate function, as requested by
Ingo.

Jesse Barnes 2547089ca2 x86/PCI: initialize PCI bus node numbers early
The current mp_bus_to_node array is initialized only by AMD specific
code, since AMD platforms have registers that can be used for
determining mode numbers.  On new Intel platforms it's necessary to
initialize this array as well though, otherwise all PCI node numbers
will be 0, when in fact they should be -1 (indicating that I/O isn't
tied to any particular node).

So move the mp_bus_to_node code into the common PCI code, and
initialize it early with a default value of -1.  This may be overridden
later by arch code (e.g. the AMD code).

With this change, PCI consistent memory and other node specific
allocations (e.g. skbuff allocs) should occur on the "current" node.
If, for performance reasons, applications want to be bound to specific
nodes, they should open their devices only after being pinned to the
CPU where they'll run, for maximum locality.
