Pull MIPS fixes from Ralf Baechle:
 "Resurrect Alchemy platforms by invoking the WAIT instructions with
  interrupts enabled.  This still leaves the race condition between
  testing TIF_NEED_RESCHED and the WAIT instruction for Alchemy
  platforms which need a different fix than other MIPS platforms.  But
  at least it gets MIPS platforms flying again.

  There are also fixes for two build errors (CONFIG_FTRACE=y with
  CONFIG_DYNAMIC_FTRACE=n) and CONFIG_VIRTUALIZATION without CONFIG_KVM"

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
  MIPS: ftrace: Add missing CONFIG_DYNAMIC_FTRACE
  MIPS: include: mmu_context.h: Replace VIRTUALIZATION with KVM
  MIPS: Alchemy: fix wait function

Pull kvm bugfixes from Gleb Natapov:
 "There is one more fix for MIPS KVM ABI here, MIPS and PPC build
  breakage fixes and a couple of PPC bug fixes"

* 'fixes' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
  kvm/ppc/booke64: Fix lazy ee handling in kvmppc_handle_exit()
  kvm/ppc/booke: Hold srcu lock when calling gfn functions
  kvm/ppc/booke64: Disable e6500 support
  kvm/ppc/booke64: Fix AltiVec interrupt numbers and build breakage
  mips/kvm: Use KVM_REG_MIPS and proper size indicators for *_ONE_REG
  kvm: Add definition of KVM_REG_MIPS
  KVM: add kvm_para_available to asm-generic/kvm_para.h

The API requires that the GET_ONE_REG and SET_ONE_REG ioctls have this
extra information encoded in the register identifiers.

The kvm_* symbols are only available if KVM is selected.

 "MIPS fixes across the field.  The only area that's standing out is the
  exception handling which received it's dose of breakage as part of the
  microMIPS patchset"

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
  MIPS: ralink: add missing SZ_1M multiplier
  MIPS: Compat: Fix cputime_to_timeval() arguments in compat binfmt_elf.
  MIPS: OCTEON: Improve _machine_halt implementation.
  MIPS: rtlx: Fix implicit declaration of function set_vi_handler()
  MIPS: Trap exception handling fixes
  MIPS: Quit exposing Kconfig symbols in uapi headers.
  MIPS: Remove duplicate definition of check_for_high_segbits.

Because not all 256 CP0 registers are ever implemented, we need a
different method of manipulating them.  Use the
KVM_SET_ONE_REG/KVM_GET_ONE_REG mechanism.

Now unused code and definitions are removed.
