Pull MIPS updates from Ralf Baechle:
- More work on DT support for various platforms
- Various fixes that were to late to make it straight into 3.9
- Improved platform support, in particular the Netlogic XLR and
BCM63xx, and the SEAD3 and Malta eval boards.
- Support for several Ralink SOC families.
- Complete support for the microMIPS ASE which basically reencodes the
existing MIPS32/MIPS64 ISA to use non-constant size instructions.
- Some fallout from LTO work which remove old cruft and will generally
make the MIPS kernel easier to maintain and resistant to compiler
optimization, even in absence of LTO.
- KVM support. While MIPS has announced hardware virtualization
extensions this KVM extension uses trap and emulate mode for
virtualization of MIPS32. More KVM work to add support for VZ
hardware virtualizaiton extensions and MIPS64 will probably already
be merged for 3.11.
Most of this has been sitting in -next for a long time. All defconfigs
have been build or run time tested except three for which fixes are being
sent by other maintainers.

Reorganize some of the GIC clocksource driver code. Below is a list of
the various changes.
* No longer select CSRC_GIC by default for Malta platform.
* Limit choice for either the GIC or R4K clocksource, not both.
* Change location in Makefile.
* Created new 'gic_read_count' function in common 'irq-gic.c' file.
* Change 'git_hpt_read' function in 'csrc-gic.c' to use new function.
* Surround GIC specific code in Malta platform code with #ifdef's.
* Only initialize the GIC clocksource if it was selected. Original
code called it unconditionally if a GIC was found.

This adds the option to build the Linux kernel using only the
microMIPS ISA. The resulting kernel binary is, at a minimum,
20% smaller than using the MIPS32R2 ISA.

GENERIC_GPIO has been made equivalent to GPIOLIB in architecture code
and all driver code has been switch to depend on GPIOLIB. It is thus

Just like the OHCI counter part we just can remove the architecture
specific symbols which prevent these configuration symbols from being
selected by platforms/architectures requiring it. The original
implementation did not scale at all since it required each and every
single architecture to be added for these configuration symbols to be
selected. Now it is up to the EHCI driver and/or platform to select
these configuration symbols accordingly.

The MIPS implementation of transparent huge-pages (THP) is 64-bit only,
and of course also requires that the CPU supports huge-pages.
Currently it's entirely possible to enable THP in other configurations,
which then fail to build due to pfn_pmd() not being defined.

Pull MIPS updates from Ralf Baechle:
o Add basic support for the Mediatek/Ralink Wireless SoC family.
o The Qualcomm Atheros platform is extended by support for the new
QCA955X SoC series as well as a bunch of patches that get the code
ready for OF support.
o Lantiq and BCM47XX platform have a few improvements and bug fixes.
o MIPS has sent a few patches that get the kernel ready for the
upcoming microMIPS support.
o The rest of the series is made up of small bug fixes and cleanups
that relate to various parts of the MIPS code. The biggy in there is
a whitespace cleanup. After I was sent another set of whitespace
cleanup patches I decided it was the time to clean the whitespace
"issues" for once and and that touches many files below arch/mips/.
Fix up silly conflicts, mostly due to whitespace cleanups.

All the boot loaders I have seen are booting the kernel in raw mode by
default. CFE seems to support elf kernel images too, but the default
case is raw for the devices I know of. Select this option to make the
kernel boot on most of the devices with the default options.

Pull signal handling cleanups from Al Viro:
"This is the first pile; another one will come a bit later and will
contain SYSCALL_DEFINE-related patches.
- a bunch of signal-related syscalls (both native and compat)
unified.
- a bunch of compat syscalls switched to COMPAT_SYSCALL_DEFINE
(fixing several potential problems with missing argument
validation, while we are at it)
- a lot of now-pointless wrappers killed
- a couple of architectures (cris and hexagon) forgot to save
altstack settings into sigframe, even though they used the
(uninitialized) values in sigreturn; fixed.
- microblaze fixes for delivery of multiple signals arriving at once
- saner set of helpers for signal delivery introduced, several
architectures switched to using those."

Pull driver core patches from Greg Kroah-Hartman:
"Here is the big driver core merge for 3.9-rc1
There are two major series here, both of which touch lots of drivers
all over the kernel, and will cause you some merge conflicts:
- add a new function called devm_ioremap_resource() to properly be
able to check return values.
- remove CONFIG_EXPERIMENTAL
Other than those patches, there's not much here, some minor fixes and
updates"

The CONFIG_EXPERIMENTAL config item has not carried much meaning for a
while now and is almost always enabled by default. As agreed during the
Linux kernel summit, remove it from any "depends on" lines in Kconfigs.
