Merge "omap fixes against v3.18-rc2" from Tony Lindgren:

Few fixes for omaps to enable NAND BCH so devices won't
produce errors when booted with omap2plus_defconfig, and
reduce bloat by making IPV6 a loadable module.

Also let's add a warning about legacy boot being deprecated
for omap3.

We now have things working with device tree, and only omap3 is
still booting in legacy mode. So hopefully this warning will
help move the remaining legacy mode users to boot with device
tree.

As the total reduction of code and static data is somewhere
around 20000 lines of code once we remove omap3 legacy mode
booting, we really do want to make omap3 to boot also in
device tree mode only over the next few merge cycles.

"This is a pretty large update. I think it is roughly as big as what I
usually had for the _whole_ rc period.

There are a few bad bugs where the guest can OOPS or crash the host.
We have also started looking at attack models for nested
virtualization; bugs that usually result in the guest ring 0 crashing
itself become more worrisome if you have nested virtualization,
because the nested guest might bring down the non-nested guest as
well. For current uses of nested virtualization these do not really
have a security impact, but you never know and bugs are bugs
nevertheless.

A lot of these bugs are in 3.17 too, resulting in a large number of
stable@ Ccs. I checked that all the patches apply there with no
conflicts"

Pull KVM updates from Paolo Bonzini:
"Fixes and features for 3.18.

Apart from the usual cleanups, here is the summary of new features:

- s390 moves closer towards host large page support

- PowerPC has improved support for debugging (both inside the guest
and via gdbstub) and support for e6500 processors

- ARM/ARM64 support read-only memory (which is necessary to put
firmware in emulated NOR flash)

- x86 has the usual emulator fixes and nested virtualization
improvements (including improved Windows support on Intel and
Jailhouse hypervisor support on AMD), adaptive PLE which helps
overcommitting of huge guests. Also included are some patches that
make KVM more friendly to memory hot-unplug, and fixes for rare
caching bugs.

Two patches have trivial mm/ parts that were acked by Rik and Andrew.

Note: I will soon switch to a subkey for signing purposes"

kvm-vfio: do not use module_init

/me got confused between the kernel and QEMU. In the kernel, you can
only have one module_init function, and it will prevent unloading the
module unless you also have the corresponding module_exit function.

So, commit 80ce1639727e (KVM: VFIO: register kvm_device_ops dynamically,
2014-09-02) broke unloading of the kvm module, by adding a module_init
function and no module_exit.

Repair it by making kvm_vfio_ops_init weak, and checking it in
kvm_init.
