Merge tag 'kvm-arm-for-4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into kvm-next
KVM/ARM changes for Linux v4.5 - Complete rewrite of the arm64 world switch in C, hopefully paving the way for more sharing with the 32bit code, better maintainability and easier integration of new features. Also smaller and slightly faster in some cases... - Support for 16bit VM identifiers - Various cleanups

-Known issues & workaround
--------------------------
-
-Some of the device drivers used on keystone are re-used from that from
-DaVinci and other TI SoCs. These device drivers may use clock APIs directly.
-Some of the keystone specific drivers such as netcp uses run time power
-management API instead to enable clock. As this API has limitations on
-keystone, following workaround is needed to boot Linux.
-
- Add 'clk_ignore_unused' to the bootargs env variable in u-boot. Otherwise
- clock frameworks will try to disable clocks that are unused and disable
- the hardware. This is because netcp related power domain and clock
- domains are enabled in u-boot as run time power management API currently
- doesn't enable clocks for netcp due to a limitation. This workaround is
- expected to be removed in the future when proper API support becomes
- available. Until then, this work around is needed.
