The Freescale DIU video controller supports five video "modes", but only
the first two are used by the driver. The other three are special modes
that don't make sense for a framebuffer driver. Therefore, there's no
point in keeping a global variable that indicates which mode we're
supposed to use.

Apple Quad G5 has some oddity in it's device-tree which causes the new
generic matching code to fail to relate nodes for PCI-E devices below U4
with their respective struct pci_dev. This breaks graphics on those
machines among others.
This fixes it using a quirk which copies the node pointer from the host
bridge for the root complex, which makes the generic code work for the
children afterward.

In commit 9aa3283595451ca093500ff0977b106e1f465586 (ehea/ibm*: Move the
IBM drivers) the IBM_NEW_EMAC* were renames to IBM_EMAC*
The conversion was incomplete so that even if the driver was added to
the .config it wasn't built, but there were no errors). In this commit
we also update the various defconfigs that use EMAC to use the new
Kconfig symbol, and explicitly add the NET_VENDOR_IBM guard.
We do not explicitly select the Kconfig dependencies, as this would force
EMAC on. Doing it in the defconfig allows more flexibility.
Tested on a canyondlands board.

Recent versions of firmware will fail to unmap the virtual processor
area if we have a dispatch trace log registered. This causes kexec
to fail.
If a trace log is registered this patch unregisters it before the
SLB shadow and virtual processor areas, fixing the problem.
The address argument is ignored by firmware on unregister so we
may as well remove it.

KVM_GUEST adds a 1 MB array to the kernel (kvm_tmp) which grew
my kernel enough to cause it to fail to boot.
Dynamically allocating or reducing the size of this array is a
good idea, but in the meantime I think it makes sense to make
KVM_GUEST default to n in order to minimise surprises.

Change the string to check for CAMP mode boot on MPC85xx (eg. P2020) to match
the one in the corresponding dts files (p2020rdb_camp_core{0,1}.dts).
Without this fix the mpic is configured as in the SMP boot mode, which causes
the first core to report a protected source interrupt error for devices
of the other core and lock up.
Also add MPIC_SINGLE_DEST_CPU on both P2020 based architectures in CAMP
mode as suggested by Scott Wood. Thanks.

Btrfs needs to be able to control how filemap_write_and_wait_range() is called
in fsync to make it less of a painful operation, so push down taking i_mutex and
the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some
file systems can drop taking the i_mutex altogether it seems, like ext3 and
ocfs2. For correctness sake I just pushed everything down in all cases to make
sure that we keep the current behavior the same for everybody, and then each
individual fs maintainer can make up their mind about what to do from there.

Instead of using ill-defined numbers (0, 1, and 2) for the monitor port, allow
the user to specify the port by name ("dvi", "lvds", or "dlvds"). This works
on the kernel command line, the module command-line, and the sysfs "monitor"
device.
Note that changing the monitor port does not currently work on the P1022DS,
because the code that talks to the PIXIS FPGA is broken.

Instead of branching out-of-line with the DO_KVM macro to check if we
are in a KVM guest at the time of an interrupt, this moves the KVM
check inline in the first-level interrupt handlers. This speeds up
the non-KVM case and makes sure that none of the interrupt handlers
are missing the check.
Because the first-level interrupt handlers are now larger, some things
had to be move out of line in exceptions-64s.S.
This all necessitated some minor changes to the interrupt entry code
in KVM. This also streamlines the book3s_32 KVM test.

Just compiling pseries in the kernel causes it to override
memory_block_size_bytes() regardless of what is the runtime
platform.
This cleans up the implementation of that function, fixing
a bug or two while at it, so that it's harmless (and potentially
useful) for other platforms. Without this, bugs in that code
would trigger a WARN_ON() in drivers/base/memory.c when
booting some different platforms.
If/when we have another platform supporting memory hotplug we
might want to either move that out to a generic place or
make it a ppc_md. callback.

Under the FSL Hypervisor we triggered a BUG_ON in mpc85xx_smp_init that
expected smp_ops.message_pass to be explicity set. However recent
changes allows smp_ops.message_pass to be NULL and handled by default

All other sections except init were removed in v2.6.15 by
6c45ab992e4299c869fb26427944a8f8ea177024 (powerpc: Remove section

This patch also removes updating ppc_md.progress to NULL in the powermac

On pseries machines, consoles are provided by the hypervisor using
a low level get_chars/put_chars type interface. However, this is
really just a transport to the service processor which implements
them either as "raw" console (networked consoles, HMC, ...) or as
"hvsi" serial ports.
The later is a simple packet protocol on top of the raw character
interface that is supposed to convey additional "serial port" style
semantics. In practice however, all it does is provide a way to
read the CD line and set/clear our DTR line, that's it.
We currently implement the "raw" protocol as an hvc console backend
(/dev/hvcN) and the "hvsi" protocol using a separate tty driver
(/dev/hvsi0).
However this is quite impractical. The arbitrary difference between
the two type of devices has been a major source of user (and distro)
confusion. Additionally, there's an additional mini -hvsi implementation
in the pseries platform code for our low level debug console and early
boot kernel messages, which means code duplication, though that low
level variant is impractical as it's incapable of doing the initial
protocol negociation to establish the link to the FSP.
This essentially replaces the dedicated hvsi driver and the platform
udbg code completely by extending the existing hvc_vio backend used
in "raw" mode so that:
- It now supports HVSI as well
- We add support for hvc backend providing tiocm{get,set}
- It also provides a udbg interface for early debug and boot console
This is overall less code, though this will only be obvious once we
remove the old "hvsi" driver, which is still available for now. When
the old driver is enabled, the new code still kicks in for the low
level udbg console, replacing the old mini implementation in the platform
code, it just doesn't provide the higher level "hvc" interface.
In addition to producing generally simler code, this has several benefits
over our current situation:
- The user/distro only has to deal with /dev/hvcN for the hypervisor
console, avoiding all sort of confusion that has plagued us in the past
- The tty, kernel and low level debug console all use the same code
base which supports the full protocol establishment process, thus the
console is now available much earlier than it used to be with the
old HVSI driver. The kernel console works much earlier and udbg is
available much earlier too. Hackers can enable a hard coded very-early
debug console as well that works with HVSI (previously that was only
supported for the "raw" mode).
I've tried to keep the same semantics as hvsi relative to how I react
to things like CD changes, with some subtle differences though:
- I clear DTR on close if HUPCL is set
- Current hvsi triggers a hangup if it detects a up->down transition
on CD (you can still open a console with CD down). My new implementation
triggers a hangup if the link to the FSP is severed, and severs it upon
detecting a up->down transition on CD.

Reconfiguration notifier call for device node may fail by several reasons,
but it always assumes kmalloc failures.
This enables reconfiguration notifier call chain to get the actual error
code rather than -ENOMEM by converting all reconfiguration notifier calls
to return encapsulate error code with notifier_from_errno().

This introduces pSeries_reconfig_notify() as a just wrapper of
blocking_notifier_call_chain() for pSeries_reconfig_chain.
This is a preparation to improvement of error code on reconfiguration
notifier failure.

The Freescale hypervisor does not allow guests to write to the timebase
registers (virtualizing the timebase register was deemed too complicated),
so don't try to synchronize the timebase registers when we're running
under the hypervisor.
This typically happens when kexec support is enabled.

mpc8610hpcd_set_pixel_clock() calculates the correct value of the PXCLK
bits in the CLKDVDR register for a given pixel clock rate. The code which
performs this calculation is overly complicated and includes an error
estimation routine that doesn't work most of the time anyway. Replace the
code with the simpler routine that's currently used on the P1022DS.
