When building arch/powerpc/platforms/powermac/pic.c when !CONFIG_ADB_PMU
we get the following warnings:
arch/powerpc/platforms/powermac/pic.c: In function 'pmacpic_find_viaint':

pmu_sys_suspended is declared extern when:
defined(CONFIG_PM_SLEEP) && defined(CONFIG_PPC32)
but only defined when:
defined(CONFIG_SUSPEND) && defined(CONFIG_PPC32)
which is wrong. Let's fix that.

Currently, if drivers/macintosh/apm_emu is a module and the config
doesn't have CONFIG_SUSPEND we get:
ERROR: "pmu_batteries" [drivers/macintosh/apm_emu.ko] undefined!
ERROR: "pmu_battery_count" [drivers/macintosh/apm_emu.ko] undefined!
ERROR: "pmu_power_flags" [drivers/macintosh/apm_emu.ko] undefined!
on PPC32. The variables aren't wrapped in '#if defined(CONFIG_SUSPEND)'
so we probably shouldn't wrap the exports either. This removes the
CONFIG_SUSPEND part of the export, which fixes compilation on ppc32.

The PMU backlight code would kick in during sleep/resume even on
machines that use a different backlight method. This breaks
sleep on some PowerBooks.
This fixes it by adding a flag to indicate whether the backlight
is controlled by the PMU, and testing that before trying to use
the PMU to turn off the backlight during sleep.

A bogus test for unassigned resources that came from our 32-bit
PCI code ended up being "merged" by my previous patch series,
breaking some 64-bit setups where devices have legal resources
ending at 0xffffffff.
This fixes it by completely changing the test. We now test for
res->start == 0, as the generic code expects, and we also only
do so on platforms that don't have the PPC_PCI_PROBE_ONLY flag
set, as there are cases of pSeries and iSeries where it could
be a valid value and those can't reassign devices.

The pattern substitution rules were failing when used with zImage-dtb
targets. If zImage-dtb.initrd was selected, the pattern substitution
would generate "zImage.initrd-dtb" instead of "zImage-dtb.initrd" which
caused the build to fail.
This renames zImage-dtb to dtbImage to avoid the problem entirely.
By not using the zImage prefix then is no potential for namespace
collisions.

Some drivers (such as V4L2) have code that causes gcc to generate
calls to __ucmpdi2 when compiling for 32-bit powerpc, which results
in either a link-time error or a module that can't be loaded, as
we don't currently have a __ucmpdi2. This adds one so these drivers
can be used.

Some BIOSes have PNP motherboard devices with resources that
partially overlap PCI BARs. The PNP system driver claims these
motherboard resources, which prevents the normal PCI driver from
requesting them later.
This patch disables the PNP resources that conflict with PCI BARs
so they won't be claimed by the PNP system driver.
Of course, this only works if PCI devices have already been enumerated.
Currently this is the case because PCI devices are discovered before
any PNP init via this path:
acpi_pci_root_init() -> acpi_pci_root_add() -> pci_acpi_scan_root() ->
pci_scan_bus_parented() -> pci_scan_child_bus() -> ...
Avuton Olrich tested this and confirmed that it fixes his ALSA sound
card (see http://lkml.org/lkml/2008/1/27/168).

RDMA connection shutdown on an SMP machine can cause a kernel crash due
to the transport close path racing with the I/O tasklet.
Additional transport references were added as follows:
- A reference when on the DTO Q to avoid having the transport
deleted while queued for I/O.
- A reference while there is a QP able to generate events.
- A reference until the DISCONNECTED event is received on the CM ID

Introduced in commit-id 9e2779fa281cfda13ac060753d674bbcaa23367e and
ifdef'ed out for nommu in 8ca3ed87db062201e1fa15b64a9214e193fc3a8a, both
approaches end up breaking the nommu build in different ways. An
impressive feat for a 2-liner.
Current is_vmalloc_addr() users fall in to two camps:
- Determining whether to use vfree()/kfree()
- Whether to do vmlist traversal (only /proc/kcore).
Since we don't support /proc/kcore on nommu, that leaves the
vfree()/kfree() determination use cases. nommu vfree() happens to be a
wrapper to kfree() anyways, so is_vmalloc_addr() can always return 0
and end up with the right behaviour.

Commit 7143740d ("IPoIB: Add send gather support") made struct
ipoib_tx_buf significantly larger, since the mapping member changed
from a single u64 to an array with MAX_SKB_FRAGS + 1 entries. This
means that allocating tx_rings with kzalloc() may fail because there
is not enough contiguous memory for the new, much bigger size. Fix
this regression by allocating the rings with vmalloc() instead.

This patch works around incorrect _PRT (PCI interrupt routing)
information from firmware. This does not fix any regressions
and can wait for the next kernel release.
On the Medion MD9580-F laptop, the BIOS says the builtin RTL8139
NIC interrupt at 00:09.0[A] is connected to \_SB.PCI0.ISA.LNKA, but
it's really connected to \_SB.PCI0.ISA.LNKB. Before this patch,
the workaround was to use "pci=routeirq". More details at
http://bugzilla.kernel.org/show_bug.cgi?id=4773.
On the Dell OptiPlex GX1, the BIOS says the PCI slot interrupt
00:0d[A] is connected to LNKB, but it's really connected to LNKA.
Before this patch, the workaround was to use "pci=routeirq".
Pierre Ossman tested a previous version of this patch and confirmed
that it fixed the problem. More details at
http://bugzilla.kernel.org/show_bug.cgi?id=5044.
On the HP t5710 thin client, the BIOS says the builtin Radeon
video interrupt at 01:00[A] is connected to LNK1, but it's really
connected to LNK3. The previous workaround was to use a custom
DSDT. I tested this patch and verified that it fixes the problem.

There is a problem in the hibernation code that triggers on some NUMA
systems on which pfn_valid() returns 'true' for some PFNs that don't
belong to any zone. Namely, there is a BUG_ON() in
memory_bm_find_bit() that triggers for PFNs not belonging to any
zone and passing the pfn_valid() test. On the affected systems it
triggers when we mark PFNs reported by the platform as not saveable,
because the PFNs in question belong to a region mapped directly using
iorepam() (i.e. the ACPI data area) and they pass the pfn_valid()
test.
Modify memory_bm_find_bit() so that it returns an error if given PFN
doesn't belong to any zone instead of crashing the kernel and ignore
the result returned by it in mark_nosave_pages(), while marking the
"nosave" memory regions.
This doesn't affect the hibernation functionality, as we won't touch
the PFNs in question anyway.

Commit 7143740d ("IPoIB: Add send gather support") made it possible
for tx_wr.num_sge to be != 1 -- this happens if send gather support is
enabled. However, the code in the connected mode post_send() function
assumes the old invariant, namely that tx_wr.num_sge is always 1. Fix
this by explicitly setting tx_wr.num_sge to 1 in the CM post_send().
