Now that xdr_inline_decode() will automatically cross into the page
buffers, we need to ensure that it doesn't exceed the total reply
message length.
This patch sets up a counter that tracks the number of words
remaining in the reply message, and ensures that xdr_inline_decode,
xdr_read_pages and xdr_enter_page respect the end of message boundary.

The actual size of the directory is unknown to the client, so it is
always requesting the maximum number it can handle. If the server
is replying with fewer entries than was requested, then that will
usually reflect the fact that we've hit the end of the directory.
Flagging it as an error is therefore incorrect.

At the moment we call kvmppc_pin_guest_page() in kvmppc_update_vpa()
with two spinlocks held: the vcore lock and the vcpu->vpa_update_lock.
This is not good, since kvmppc_pin_guest_page() calls down_read() and
get_user_pages_fast(), both of which can sleep. This bug was introduced
in 2e25aa5f ("KVM: PPC: Book3S HV: Make virtual processor area
registration more robust").
This arranges to drop those spinlocks before calling
kvmppc_pin_guest_page() and re-take them afterwards. Dropping the
vcore lock in kvmppc_run_core() means we have to set the vcore_state
field to VCORE_RUNNING before we drop the lock, so that other vcpus
won't try to run this vcore.

The orion watchdog is expecting to be passed the physcial address of
the hardware, and will ioremap() it to give a virtual address it will
use as the base address for the hardware. However, when creating the
platform resource record, a virtual address was being used.
Add the necassary #define's so we can pass the physical address as
expected.
Tested on Kirkwood and Orion5x.

In commit:
98d9986 ARM: Kirkwood: Replace clock gating
the kirkwood clock gating has been reworked. A custom variant of
clock gating, that calls a custom function before gating the clock
off, has been introduced. However in clk_register_gate_fn() this
custom function "fn" is never assigned.
This patch adds the missing fn assignment.

Commit 4d5fc58dbe34b78157c05b319669bb3e064ba8bd (ARM: remove bunch of
now unused mach/io.h files) removed the orion5x io.h. Unfortunately,
this is still needed for the definition of IO_SPACE_LIMIT which
overrides the default 64K. All Orion based systems have 1Mbyte of IO
space per PCI[e] bus, and try to request_resource() this size. Orion5x
has two such PCI buses.
It is likely that the original, removed version, was broken. This
version might be less broken. However, it has not been tested on
hardware with a PCI card, let alone hardware with a PCI card with IO
capabilities.

As per the OMAP4 documentation, audio over HDMI must be transmitted in
no-idle mode. This patch adds the HWMOD_SWSUP_SIDLE so that omap_hwmod uses
no-idle/force-idle settings instead of smart-idle mode.
This is required as the DSS interface clock is used as functional clock
for the HDMI wrapper audio FIFO. If no-idle mode is not used, audio could
be choppy, have bad quality or not be audible at all.

Until the OMAP4 code is converted to disable the use of the clock

patch populates some clock structure clockdomain names to resolve the
following warnings during kernel init:
omap_hwmod: dpll_mpu_m2_ck: missing clockdomain for dpll_mpu_m2_ck.
omap_hwmod: trace_clk_div_ck: missing clockdomain for trace_clk_div_ck.

Commit e813a55eb9c9bc6c8039fb16332cf43402125b30 ("OMAP: board-files:
remove custom PD GPIO handling for DVI output") moved TFP410 chip's
powerdown-gpio handling from the board files to the tfp410 driver. One
gpio_request_one(powerdown-gpio, ...) was mistakenly left unremoved in
the Beagle board file. This causes the tfp410 driver to fail to request
the gpio on Beagle, causing the driver to fail and thus the DVI output
doesn't work.
This patch removes several boot errors from board-omap3beagle.c:
- gpio_request: gpio--22 (DVI reset) status -22
- Unable to get DVI reset GPIO
There is a combination of leftover code and revision confusion.
Additionally, xM support is currently a hack.
For original Beagleboard this removes the double initialization of GPIO
170, properly configures it as an output, and wraps the initialization
in an if block so that xM does not attempt to request it.
For Beagleboard xM it removes reference to GPIO 129 which was part
of rev A1 and A2 designs, but never functioned. It then properly assigns
beagle_dvi_device.reset_gpio in beagle_twl_gpio_setup and removes the
hack of initializing it high. Additionally, it uses
gpio_set_value_cansleep since this GPIO is connected through i2c.
Unfortunately, there is no way to tell the difference between xM A2 and
A3. However, GPIO 129 does not function on rev A1 and A2, and the TWL
GPIO used on A3 and beyond is not used on rev A1 and A2, there are no
problems created by this fix.
Tested on Beagleboard-xM Rev C1 and Beagleboard Rev B4.

When booting with device-tree on an OMAP2420H4, the kernel is hanging when
initialising the interrupts and following kernel dumps is seen ...

The OMAP2 interrupt controller binding is missing the number of interrupts and
interrupt controller register address. Adding these fixes the problem.

Here's one more gpio_to_irq conversion that we missed
earlier. Tested with n800 in gadget mode using USB_ETH.

Commit 62285963 (usb: musb: drop a gigantic amount of ifdeferry)
got rid of a bunch of ifdefs in the MUSB code. Looks like the
platform init code is still using these dropped defines though,
which in many cases results the board defaulting always to host
mode.
Currently the situation is that USB_MUSB_HDRC is the main
Kconfig option with additional USB_GADGET_MUSB_HDRC so only
these two should be used to select between host and OTG mode.
Fix the situation for omaps. The following users should fix the
platform init code in a similar way:
Dropped Kconfig option Current users
USB_MUSB_OTG blackfin, davinci, not in Kconfigs
USB_MUSB_PERIPHERAL davinci, not in Kconfigs
USB_MUSB_HOST davinci, not in Kconfigs
USB_MUSB_HDRC_HCD blackfin, not in Kconfigs
USB_MUSB_OTG blackfin, not in Kconfigs

This solves a section mismatch warning. I hadn't noticed this before,
because my compiler was inlining tegra_cpu_reset_handler_enable() inside
tegra_cpu_reset_handler_init(), which is already __init, but I switched
compilers and it stopped doing that.
