7c40542ffa [POWERPC] Fix bug adding properties with flatdevtree.c's ft_set_prop()
ft_set_prop() from flatdevtree.c in the zImage wrapper will either
replace an existing property in the flat device tree, or add a new
property definiion if the given property isn't present.

However, when adding properties, it adds the property definition
immediately before the node's END_NODE tag, potentially after any
subnode definitions for the node.  This confuses the kernel flat tree
parser in prom.c which assumes that all property definitions for a
node come before all subnode definitions.

This patch corrects ft_set_prop() so that it adds new properties
before the first subnode, instead of before the END_NODE tag.

e3d67b663b [POWERPC] Remove fixup_bigphys_addr() for arch/powerpc to avoid link error
There are no actual implementations of fixup_bigphys_addr() in
arch/powerpc, and with a 64-bit aware ioremap() and so forth, it
should no longer be necessary.  This patch removes the last dregs of
fixup_bigphys_addr() from arch/powerpc.

In fact, the only reason this hasn't caused link errors already is
that nobody must have tried using one of the small number of drivers
using io_remap_pfn_range() on one of the small number of platforms
which are 32-bit but define CONFIG_PHYS_64BIT.  Nonetheless this fixes
a bug, and should go into 2.6.22.

When an rheap is created, the caller can specify the alignment to use.  In
rh_alloc_align(), if a free block is found that is the exact size needed
(including extra space for alignment), that configured alignment value is not
used to align the pointer.  Instead, the default alignment is used.  If the
default alignment is smaller than the configured alignment, then the returned
value will not be aligned correctly.

52ade9b3b9 Fix ACPI suspend / device suspend ordering problem
In commit e3c7db621b we fixed the resume
ordering, so that the ACPI low-level resume code was called before the
actual driver resume was called. However, that broke the nesting logic
of suspend and resume, and we continued to suspend the devices _after_
we the ACPI device suspend code was called.

That resulted in us saving PCI state for devices that had already been
changed by ACPI, and in some cases disabled entirely (causing the PCI
save_state to be all-ones).  Which in turn caused the wrong state to be
written back on resume.

This moves the ACPI device suspend to after the device model per-device
suspend() calls. This fixes the bogus state save.

Thanks to Lukáš Hejtmánek for testing.

AC97 codecs.
 o Only register/deregister this custom codec device with the AC97 bus.
The generic AC97 driver already does this for generic codec devices.

da071b42f7 libata: fix shutdown warning message printing
Unlocking ap->lock and ssleeping don't work because SCSI commands can
be issued from completion path without context.  Reimplement delayed
completion by allowing translation functions to override
qc->scsidone(), storing the original completion function to
scmd->scsi_done() and overriding qc->scsidone() with a function which
schedules delayed invocation of scmd->scsi_done().

This isn't pretty at all but all the ugly parts are thankfully
contained in the stop translation path where the compat feature is
implemented.

6ddcd3b020 libata: during revalidation, check n_sectors after device is configured
Device might be resized during ata_dev_configure() due to HPA or
(later) ACPI _GTF.  Currently it's worked around by caching n_sectors
before turning off HPA.  The cached original size is overwritten if
the device is reconfigured without being hardreset - which always
happens after configuring trasnfer mode.  If the device gets hardreset
for some reason after that, revalidation fails with -ENODEV.

This patch makes size checking more robust by moving n_sectors check
from ata_dev_reread_id() to ata_dev_revalidate() after the device is
fully configured.  No matter what happens during configuration, a
device must have the same n_sectors after fully configured to be
treated as the same device.

fe30911b34 libata: separate out ata_dev_reread_id()
Separate out ata_dev_reread_id() from ata_dev_revalidate().
ata_dev_reread_id() reads IDENTIFY page and determines whether the
same device is still there.  ata_dev_revalidate() reconfigures after
reread completes.  This will be used by ACPI update.

c7754d465b [SPARC64]: Add hypervisor API negotiation and fix console bugs.
Hypervisor interfaces need to be negotiated in order to use
some API calls reliably.  So add a small set of interfaces
to request API versions and query current settings.

This allows us to fix some bugs in the hypervisor console:

1) If we can negotiate API group CORE of at least major 1
   minor 1 we can use con_read and con_write which can improve
   console performance quite a bit.

2) When we do a console write request, we should hold the
   spinlock around the whole request, not a byte at a time.
   What would happen is that it's easy for output from
   different cpus to get mixed with each other.

3) Use consistent udelay() based polling, udelay(1) each
   loop with a limit of 1000 polls to handle stuck hypervisor
   console.
