Pull KVM leftovers from Radim Krčmář:
"This is a combination of two pull requests for 4.7-rc8 that were not
merged due to looking hairy. I have changed the tag message to focus
on circumstances of contained reverts as they were likely the reason
behind rejection.
This merge introduces three patches that are later reverted,
- Switching of MSR_TSC_AUX in SVM was thought to cause a host
misbehavior, but it was later cleared of those doubts and the patch
moved code to a hot path, so we reverted it. That patch also
needed a fix for 32 bit builds and both were reverted in one go.
- Al Viro noticed that a fix for a leak in an error path was not
valid with the given API and provided a better fix, so the original
patch was reverted.
Then there are two VMX fixes that move code around because VMCS was
not accessed between vcpu_load() and vcpu_put(), a simple ARM VHE fix,
and two one-liners for PML and MTRR"

CONFIG_RANDOMIZE_MEMORY=y randomizes the physical memmap and thus the
address where the initrd is located. Therefore, we need to add the
offset KASLR put us to in order to find the initrd again on the AP path.
In the future, we will get rid of the initrd address caching and query
the address on both the BSP and AP paths but that would need more work.
Thanks to Nicolai Stange for the good bisection and debugging work.

A two-level page-table can map up to 1GB of address space.

ASoC: Updates for v4.8
Not really any framework work this time around (though we have seen one
of the Analog Devices drivers move more to the clock API which is good
to see) but rather a lot of new drivers:
- Lots of updates for the Intel drivers, mostly board support and bug
fixing, and to the NAU8825 driver.
- Work on generalizing bits of simple-card to allow more code sharing
with the Renesas rsrc-card (which can't use simple-card due to DPCM).
- Removal of the Odroid X2 driver due to replacement with simple-card.
- Support for several new Mediatek platforms and associated boards.
- New drivers for Allwinner A10, Analog Devices ADAU7002, Broadcom
Cygnus, Cirrus Logic CS35L33 and CS53L30, Maxim MAX8960 and MAX98504,
Realtek RT5514 and Wolfson WM8758

The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either

Using the macro makes the code more readable by helping abstract away some

Currently, SGMII based 1G rely on the hardware registers for link state
and sometimes it's not reliable. To get most accurate link state, this
interface has to use the MDIO bus to poll the PHY.
In X-Gene SoC, MDIO bus is shared across RGMII and SGMII based 1G
interfaces, so adding this driver to manage MDIO bus. This driver
registers the mdio bus and registers the PHYs connected to it.

struct tc_action is confusing, currently we use it for two purposes:
1) Pass in arguments and carry out results from helper functions
2) A generic representation for tc actions
The first one is error-prone, since we need to make sure we don't
miss anything. This patch aims to get rid of this use, by moving
tc_action into tcf_common, so that they are allocated together
in hashtable and can be cast'ed easily.
And together with the following patch, we could really make
tc_action a generic representation for all tc actions and each
type of action can inherit from it.

alloc_workqueue replaces deprecated create_singlethread_workqueue().
A dedicated workqueue has been used since the workitems are being used
on a packet tx/rx path. Hence, WQ_MEM_RECLAIM has been set to guarantee
forward progress under memory pressure.
An ordered workqueue has been used since workitems &cfhsi->wake_up_work
and &cfhsi->wake_down_work cannot be run concurrently.
Calls to flush_workqueue() before destroy_workqueue() have been dropped
since destroy_workqueue() itself calls drain_workqueue() which flushes
repeatedly till the workqueue becomes empty.

The recent commit to rework the hash MMU setup broke the build when

Removing the else clause opens the possibility that we don't set any

that we correctly initialised at least one member of the struct.
