We now keep a single list of IDs that includes both the _HID and any
_CIDs. We no longer need to keep track of whether the device has a _CID.

There's no need to treat _HID and _CID differently. Keeping them in
a single list makes code that uses the IDs a little simpler because it
can just traverse the list rather than checking "do we have a HID?",
"do we have any CIDs?"

This makes sure every acpi_device has at least one ID. If we build an
acpi_device for a namespace node with no _HID or _CID, we sometimes
synthesize an ID like "LNXCPU" or "LNXVIDEO". If we don't even have
that, give it a default "device" ID.
Note that this means things like:
/sys/devices/LNXSYSTM:00/LNXSYBUS:00/HWP0001:00/HWP0002:04/device:00
(a PCI slot SxFy device) will have "hid" and "modprobe" entries, where
they didn't before. These aren't very useful (a HID of "device" doesn't
tell you what *kind* of device it is, so it doesn't help find a driver),
but I don't think they're harmful.

This makes \_SB_ show up as /sys/devices/LNXSYSTM:00/LNXSYBUS:00
rather than "device:00". This has been broken for a loooong time
(at least since 2.6.13) because device->parent is an acpi_device
pointer, not a handle.

acpi_bus_scan() traverses the namespace to enumerate devices and uses
acpi_add_single_object() to create acpi_devices. When the platform
notifies us of a hot-plug event, we need to traverse part of the namespace
again to figure out what appeared or disappeared. (We don't yet call
acpi_bus_scan() during hot-plug, but I plan to do that in the future.)
This patch makes acpi_add_single_object() notice when we already have
an acpi_device, so we don't need to make a new one.

This patch adds acpi_bus_type_and_status(), which determines the type
of the object and whether we want to build an acpi_device for it. If
it is acpi_device-worthy, it returns the type and the device's current
status.

Add acpi_bus_get_status_handle() so we can get the status of a namespace
object before building a struct acpi_device.
This removes a use of "device->flags.dynamic_status", a cached indicator of
whether _STA exists. It seems simpler and more reliable to just evaluate
_STA and catch AE_NOT_FOUND errors.

acpi_bus_scan() currently walks the namespace manually. This patch changes
it to use acpi_walk_namespace() instead.
Besides removing some complicated code, this means we take advantage of the
namespace locking done by acpi_walk_namespace(). The locking isn't so
important at boot-time, but I hope to eventually use this same path to
handle hot-addition of devices, when it will be important.
Note that acpi_walk_namespace() does not actually visit the starting node
first, so we need to do that by hand first.

We can identify the root of the ACPI device tree by the fact that it
has no parent. This is simpler than passing around ACPI_BUS_TYPE_SYSTEM
and will help remove special treatment of the device tree root.
Currently, we add the root by hand with ACPI_BUS_TYPE_SYSTEM. If we
traverse the tree treating the root as just another device and use
acpi_get_type(), the root shows up as ACPI_TYPE_DEVICE.

This patch changes the order so we enumerate in the "root, namespace,
functional fixed" order instead of the "root, functional fixed, namespace"
order. When I change acpi_bus_scan() to use acpi_walk_namespace(), it
will use the former order, so this patch isolates the order change for
bisectability.

This patch changes acpi_bus_scan() to take an acpi_handle rather than an
acpi_device pointer. I plan to use acpi_bus_scan() in the hotplug path,
and I'd rather not assume that notifications only go to nodes that already
have acpi_devices.
This will also help remove the special case for adding the root node. We
currently add the root by hand before acpi_bus_scan(), but using a handle
here means we can start the acpi_bus_scan() directly with the root even
though it doesn't have an acpi_device yet.
Note that acpi_bus_scan() currently adds and/or starts the *children* of
its device argument. It doesn't do anything with the device itself.

This patch adds acpi_bus_get_parent(), which ascends the namespace until
it finds a parent with an acpi_device.
Then we use acpi_bus_get_parent() in acpi_add_single_object(), so callers
don't have to figure out or keep track of the parent acpi_device.

We only pass the "type" to acpi_device_set_context() so we know whether
the device has a handle to which we can attach the acpi_device pointer.
But it's safer to just check for the handle directly, since it's in the
acpi_device already.

Most uses of the ACPI bus device_type (ACPI_BUS_TYPE_DEVICE,
ACPI_BUS_TYPE_POWER, etc) are during device initialization, but
we do need it later for notify handler installation, since that
is different for fixed hardware devices vs. namespace devices.
This patch saves the device_type in the acpi_device structure,
so we can check that rather than comparing against the _HID string.

In several cases, functions take handle and parent device pointers in
addition to acpi_device pointers. But the acpi_device structure contains
both the handle and the parent pointer, so it's pointless and error-prone
to pass them all. This patch removes the unnecessary "handle" and "parent"
arguments.

Commit 15b8dd53f5ffa changed info->hardware_id from a static array to
a pointer. If hardware_id is non-NULL, it points to a NULL-terminated
string, so we don't need to terminate it explicitly. However, it may
be NULL; in that case, we *can't* add a NULL terminator.
This causes a NULL pointer dereference oops for devices without _HID.

This is because the driver manages interrupts without checking for
netif_running().
Though, there are few other issues with suspend/resume in this driver.
The intention of calling free_irq() in suspend() was to avoid any
possible spurious interrupts (see commit 5b039e681b8c5f30aac9cc04385
"3c59x PM fixes"). But,
- On resume, the driver was requesting IRQ just after pci_set_master(),
but before vortex_up() (which actually resets 3c59x chips).
- Issuing free_irq() on a shared IRQ doesn't guarantee that a buggy
HW won't trigger spurious interrupts in another driver that
requested the same interrupt. So, if we want to protect from
unexpected interrupts, then on suspend we should issue disable_irq(),
not free_irq().

Multicast joins can succeed even if the IB port is down. This happens
when the SM runs on the same port with the requesting port. However,
IPoIB calls netif_carrier_on() when the join of the broadcast group
succeeds, without caring about the state of the IB port. The result
is an IPoIB interface in RUNNING state but without an active IB port
to support it.
If a bonding interface uses this IPoIB interface as a slave it might
not detect that this slave is almost useless and failover
functionality will be damaged. The fix checks the state of the IB
port in the carrier_task before calling netif_carrier_on().

In this case, the calls to request_mem_region, ioremap, and
release_mem_region all have a consistent length argument, len, but since
in other files (res->end - res->start) + 1, equivalent to
resource_size(res), is used for a resource-typed structure res, one could
consider whether the same should be done here.
The problem was found using the following semantic patch:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@@
struct resource *res;
@@
- (res->end - res->start) + 1
+ resource_size(res)
@@
struct resource *res;
@@
- res->end - res->start
+ BAD(resource_size(res))

id_reg.if_mode might be unitialized when (*mrq)->error is nonzero. move
dev_dbg() inside the if so that we are sure we can use id_reg values.
