With both _numa_init() methods converted and the rest of init code
adjusted, numa_32.c now can switch from the 32bit only init code to
the common one in numa.c.

* Shim get_memcfg_*()'s are dropped and initmem_init() calls
  x86_numa_init(), which is updated to handle NUMAQ.

* All boilerplate operations including node range limiting, pgdat
  alloc/init are handled by numa_init().  32bit only implementation is
  removed.

* 32bit numa_add_memblk(), numa_set_distance() and
  memory_add_physaddr_to_nid() removed and common versions in
  numa_32.c enabled for 32bit.

This change causes the following behavior changes.

* NODE_DATA()->node_start_pfn/node_spanned_pages properly initialized
  for 32bit too.

* Much more sanity checks and configuration cleanups.

* Proper handling of node distances.

* The same NUMA init messages as 64bit.

setup_node_bootmem() is taken from 64bit and doesn't use remap
allocator.  It's about to be shared with 32bit so add support for it.
If NODE_DATA is remapped, it's noted in the debug message and node
locality check is skipped as the __pa() of the remapped address
doesn't reflect the actual physical address.

On 64bit, remap allocator becomes noop and doesn't affect the
behavior.

Generic NUMA init code was moved to numa.c from numa_64.c but is still
guaraded by CONFIG_X86_64.  This patch removes the compile guard and
enables compiling on 32bit.

* numa_add_memblk() and numa_set_distance() clash with the shim
  implementation in numa_32.c and are left out.

* memory_add_physaddr_to_nid() clashes with 32bit implementation and
  is left out.

* MAX_DMA_PFN definition in dma.h moved out of !CONFIG_X86_32.

* node_data definition in numa_32.c removed in favor of the one in
  numa.c.

Update numaq such that it calls numa_add_memblk() and sets
numa_nodes_parsed instead of directly diddling with NUMA states.  The
original get_memcfg_numaq() is renamed to numaq_numa_init() and new
get_memcfg_numaq() is created in numa_32.c.

The shim numa_add_memblk() implementation handles node_start/end_pfn[]
and node_set_online() for nodes with memory.  The new
get_memcfg_numaq() exactly the same with get_memcfg_from_srat() other
than calling the numaq init function.  Things get_memcfgs_numaq() do
are not strictly necessary for numaq but added for consistency and to
help unifying NUMA init handling.

SRAT support implementation in srat_32.c and srat.c are generally
similar; however, there are some differences.

First of all, 64bit implementation supports more types of SRAT
entries.  64bit supports x2apic, affinity, memory and SLIT.  32bit
only supports processor and memory.

Most other differences stem from different initialization protocols
employed by 64bit and 32bit NUMA init paths.

On 64bit,

* Mappings among PXM, node and apicid are directly done in each SRAT
  entry callback.

* Memory affinity information is passed to numa_add_memblk() which
  takes care of all interfacing with NUMA init.

* Doesn't directly initialize NUMA configurations.  All the
  information is recorded in numa_nodes_parsed and memblks.

On 32bit,

* Checks numa_off.

* Things go through one more level of indirection via private tables
  but eventually end up initializing the same mappings.

* node_start/end_pfn[] are initialized and
  memblock_x86_register_active_regions() is called for each memory
  chunk.

* node_set_online() is called for each online node.

* sort_node_map() is called.

There are also other minor differences in sanity checking and messages
but taking 64bit version should be good enough.

This patch drops the 32bit specific implementation and makes the 64bit
implementation common for both 32 and 64bit.

The init protocol differences are dealt with in two places - the
numa_add_memblk() shim added in the previous patch and new temporary
numa_32.c:get_memcfg_from_srat() which wraps invocation of
x86_acpi_numa_init().

The shim numa_add_memblk() handles the folowings.

* node_start/end_pfn[] initialization.

* node_set_online() for memory nodes.

* Invocation of memblock_x86_register_active_regions().

The shim get_memcfg_from_srat() handles the followings.

* numa_off check.

* node_set_online() for CPU nodes.

* sort_node_map() invocation.

* Clearing of numa_nodes_parsed and active_ranges on failure.

The shims are temporary and will be removed as the generic NUMA init
path in 32bit is replaced with 64bit one.

To help transition to common NUMA init, implement temporary 32bit
shims for numa_add_memblk() and numa_set_distance().
numa_add_memblk() registers the memblk and adjusts
node_start/end_pfn[].  numa_set_distance() is noop.

These shims will allow using 64bit NUMA init functions on 32bit and
gradual transition to common NUMA init path.

Instead of calling memory_present() for each region from NUMA init,
call sparse_memory_present_with_active_regions() from paging_init()
similarly to x86-64.

For flat and numaq, this results in exactly the same memory_present()
calls.  For srat, if there are multiple memory chunks for a node,
after this change, memory_present() will be called separately for each
chunk instead of being called once to encompass the whole range, which
doesn't cause any harm and actually is the better behavior.

Currently, the only meaningful user of apic->x86_32_numa_cpu_node() is
NUMAQ which returns valid mapping only after CPU is initialized during
SMP bringup; thus, the previous patch to set apicid -> node in
setup_local_APIC() makes __apicid_to_node[] always contain the correct
mapping whether custom apic->x86_32_numa_cpu_node() is used or not.

So, there is no reason to keep separate 32bit implementation.  We can
always consult __apicid_to_node[].  Move 64bit implementation from
numa_64.c to numa.c and remove 32bit implementation from numa_32.c.

Some x86-32 NUMA implementations (NUMAQ) don't initialize apicid ->
node mapping using set_apicid_to_node() during NUMA init but implement
custom apic->x86_32_numa_cpu_node() instead.

This patch automatically initializes the default apic -> node mapping
table from apic->x86_32_numa_cpu_node() from setup_local_APIC() such
that the mapping table is in sync with the actual mapping.

As the table isn't used by custom implementations, this doesn't make
any difference at this point.  This is in preparation of unifying
numa_cpu_node() between x86-32 and 64.

The only special handling NUMA needs to do for hotadd memory is
determining the node for the hotadd memory given the address of it and
there's nothing specific to specific config method used.

srat_64.c does somewhat elaborate error checking on
ACPI_SRAT_MEM_HOT_PLUGGABLE regions, remembers them and implements
memory_add_physaddr_to_nid() which determines the node for given
hotadd address.

This is almost completely redundant.  All the information is already
available to the generic NUMA code which already performs all the
sanity checking and merging.  All that's necessary is not using
__initdata from numa_meminfo and providing a function which uses it to
map address to node.

Drop the specific implementation from srat_64.c and add generic
memory_add_physaddr_to_nid() in numa_64.c, which is enabled if
CONFIG_MEMORY_HOTPLUG is set.  Other than dropping the code, srat_64.c
doesn't need any change as it already calls numa_add_memblk() for hot
pluggable regions which is enough.

While at it, change CONFIG_MEMORY_HOTPLUG_SPARSE in srat_64.c to
CONFIG_MEMORY_HOTPLUG, for NUMA on x86-64, the two are always the
same.

numa_cleanup_meminfo() trims each memblk between low (0) and
high (max_pfn) limits and discards empty ones.  However, the
emptiness detection incorrectly used equality test.  If the
start of a memblk is higher than max_pfn, it is empty but fails
the equality test and doesn't get discarded.

The condition triggers when max_pfn is lower than start of a
NUMA node and results in memory misconfiguration - leading to
WARN_ON()s and other funnies.  The bug was discovered in devel
branch where 32bit too uses this code path for NUMA init.  If a
node is above the addressing limit, max_pfn ends up lower than
the node triggering this problem.

The failure hasn't been observed on x86-64 but is still possible
with broken hardware e820/NUMA info.  As the fix is very low
risk, it would be better to apply it even for 64bit.

Fix it by using >= instead of ==.

Older AMD K8 processors (Revisions A-E) are affected by erratum
400 (APIC timer interrupts don't occur in C states greater than
C1). This, for example, means that X86_FEATURE_ARAT flag should
not be set for these parts.

This addresses regression introduced by commit
b87cf80a ("x86, AMD: Set ARAT
feature on AMD processors") where the system may become
unresponsive until external interrupt (such as keyboard input)
occurs. This results, for example, in time not being reported
