Current acpi memory hotplug just looks into the first entry of resources in
_CRS. But, _CRS can contain plural resources. So, if _CRS contains plural
resoureces, acpi memory hot add cannot add all memory.
With this patch, acpi memory hotplug can deal with Memory Device, whose
_CRS contains plural resources.
Tested on ia64 memory hotplug test envrionment (not emulation, uses alpha
version firmware which supports dynamic reconfiguration of NUMA.)
Note: Microsoft's Windows Server 2003 requires big (>4G)resoureces to be
divided into small (<4G) resources. looks crazy, but not invalid.
(See http://www.microsoft.com/whdc/system/pnppwr/hotadd/hotaddmem.mspx)
For this reason, a firmware vendor who supports Windows writes plural
resources in a _CRS even if they are contiguous.

Builds on ARM report link problems with common configurations like
statically linked NFS (for nfsroot). The symptom is that __init
section code references __exit section code; that won't work since
the exit sections are discarded (since they can never be called).
The best fix for these particular cases would be an "__init_or_exit"
section annotation.

It should be done before calling class_device_unregister() because
it will destroy the device and free memory if there are no other
references to the device.

This reverts commit e5c44fd88c.
Thanks to Daniel Ritz and Michal Piotrowski for noticing the problem.
Daniel says:
"[The] reason is a recent change that made modules always shows as
module.mod. it breaks modprobe and probably many scripts..besides
lsmod looking horrible
stuff like this in modprobe.conf:
install pcmcia_core /sbin/modprobe --ignore-install pcmcia_core; /sbin/modprobe pcmcia
makes modprobe fork/exec endlessly calling itself...until oom
interrupts it"

This patch #if 0's the no longer used dlm_dump_lock_resources().
Since this makes dlmdebug.h empty, this patch also removes this header.
Additionally, the needlessly global dlm_is_node_recovered() is made
static.

Before checking for a nonexistent lock, make sure the lockres is not marked
RECOVERING. The caller will just retry and the state should be fixed up when
recovery completes.
