Removing __init from check_platform_magic since it is called by
xen_unplug_emulated_devices in non-init contexts (It probably gets inlined
because of -finline-functions-called-once, removing __init is more to avoid
mismatch being reported).

In the past we would only use the function's value if the
returned value was not equal to 'acpi_sci_override_gsi'. Meaning
that the INT_SRV_OVR values for global and source irq were different.
But it is OK to use the function's value even when the global
and source irq are the same.

In the past (2.6.38) the 'xen_allocate_pirq_gsi' would allocate
an entry in a Linux IRQ -> {XEN_IRQ, type, event, ..} array. All
of that has been removed in 2.6.39 and the Xen IRQ subsystem uses
an linked list that is populated when the call to
'xen_allocate_irq_gsi' (universally done from any of the xen_bind_*
calls) is done. The 'xen_allocate_pirq_gsi' is a NOP and there is
no need for it anymore so lets remove it.

.. which means we can preset of NR_IRQS_LEGACY interrupts using
the 'acpi_get_override_irq' API before this loop.
This means that we can get the IRQ's polarity (and trigger) from either
the ACPI (or MP); or use the default values. This fixes a bug if we did
not have an IOAPIC we would not been able to preset the IRQ's polarity
if the MP table existed.

In the past we would guard those code segments to be dependent
on CONFIG_XEN_DOM0 (which depends on CONFIG_ACPI) so this patch is
not stricly necessary. But the next patch will merge common
HVM and initial domain code and we want to make sure the CONFIG_ACPI
dependency is preserved - as HVM code does not depend on CONFIG_XEN_DOM0.

- then MSI/MSI-x setup - PV, HVM and then initial domain case.

- lastly, the __init functions in PV, HVM, and initial domain order.

This reverts commit 7a249cf83da1813cfa71cfe1e265b40045eceb47.
That commit created a situation that could lead to a filesystem
hang. As Dave Chinner pointed out, xfs_trans_alloc() could hold a
reference to m_active_trans (i.e., keep it non-zero) and then wait
for SB_FREEZE_TRANS to complete. Meanwhile a filesystem freeze
request could set SB_FREEZE_TRANS and then wait for m_active_trans
to drop to zero. Nobody benefits from this sequence of events...

The code in setup_ioapic_irq() determines the Destination Field,
so why not also include it in the debug printk output that gets
displayed when the boot parameter "apic=debug" is used.
Before the change, "dmesg" will show:
IOAPIC[0]: Set routing entry (8-1 -> 0x31 -> IRQ 1 Mode:0 Active:0)
IOAPIC[0]: Set routing entry (8-2 -> 0x30 -> IRQ 0 Mode:0 Active:0)
IOAPIC[0]: Set routing entry (8-3 -> 0x33 -> IRQ 3 Mode:0 Active:0) ...
After the change, you will see:

IOAPIC[0]: Set routing entry (8-2 -> 0x30 -> IRQ 0 Mode:0 Active:0 Dest:0)

When IOAPIC data is displayed in "dmesg" with the help of the
boot parameter "apic=debug" certain values are not formatted
correctly wrt their size.
In the "dmesg" snippet below, note that the output for "max
redirection entries", and "IO APIC version" which are each
defined to be just 8-bits long are displayed as 2 bytes in
length. Similarly, "Dst" under the "IRQ redirection table"
should only be 8-bits long.
IO APIC #0......
...
...
.... register #01: 00170020
....... : max redirection entries: 0017
....... : PRQ implemented: 0
....... : IO APIC version: 0020
...
...
.... IRQ redirection table:

Do some formatting clean up, so you will see output like below:

Commit 2706a0bf7b ("x86, NUMA: Enable CONFIG_AMD_NUMA on 32bit
too") enabled AMD NUMA for 32bit too. Unfortunately, SPARSEMEM
on 32bit had rather coarse (512MiB) addr->node mapping
granularity due to lack of space in page->flags. This led to
boot failure on certain AMD NUMA machines which had 128MiB
alignment on nodes.
Patches to properly detect this condition and reject NUMA
configuration are posted[1] but deemed too pervasive for merge
at this point (-rc6). Disable AMD NUMA for 32bit for now and
re-enable once the detection logic is merged.

In fs/dlm/lock.c in the dlm_scan_waiters() function there are 3 small
issues:
1) There's no need to test the return value of the allocation and do a
memset if is succeedes. Just use kzalloc() to obtain zeroed memory.
2) Since kfree() handles NULL pointers gracefully, the test of
'warned' against NULL before the kfree() after the loop is completely
pointless. Remove it.
3) The arguments to kmalloc() (now kzalloc()) were swapped. Thanks to
Dr. David Alan Gilbert for pointing this out.

The raw hid output function that is supported by bluetooth low-level
hid driver does not provide an output queue and also may sleep. The
wiimote driver, though, may need to send data in atomic context so
this patch adds a buffered output queue for the wiimote driver.
We use the shared workqueue to send our buffer to the hid device.
There is always only one active worker which flushes the whole output
queue to the device. If our queue is full, every further
output is discarded.
Special care is needed in the deinitialization routine. When
wiimote_hid_remove is called, HID input is already disabled, but HID
output may still be used from our worker and is then discarded by the
lower HID layers. Therefore, we can safely disable the input layer since it
is the only layer that still sends input events.
Future sysfs attributes must be freed before unregistering input to
avoid the sysfs handlers to send input events to a non-existing input
layer.

The wiimote driver needs to send raw output reports to the wiimote
device. Otherwise we could not manage the peripherals of the wiimote
or perform memory operations on the wiimote.
We cannot use hidinput_input_event of the lowlevel hid driver, since
this does not accept raw input. Therefore, we need to use the same
function that hidraw uses to send output. Side effect is, the raw
output function is not buffered and can sleep.
