This patch series fixes a number of of KVM/ARM issues that have either
been spotted during the review of the arm64 code, or while reworking
related code.

Only the first patch fixes a potential (if unlikely) problem, the
others are either cosmetic or performance related.

Tested on TC-2, based on 3.10-rc1.

* From v2:
  - [1/7] Drop the unnecessary "TLB invalidate all", as we already do
  it on a page-per-page level.
  - [3/7] Add a cache cleaning primitive, move the cleaning outside of
  kvm_set_pte(), and clean a range as large as possible when inserting
  PTEs.
  - [4,5,7/7] New patches

Marc Zyngier (7):
  ARM: KVM: be more thorough when invalidating TLBs
  ARM: KVM: remove dead prototype for __kvm_tlb_flush_vmid
  ARM: KVM: relax cache maintainance when building page tables
  ARM: KVM: use phys_addr_t instead of unsigned long long for HYP PGDs
  ARM: KVM: don't special case PC when doing an MMIO
  ARM: KVM: get rid of S2_PGD_SIZE
  ARM: KVM: drop use of PAGE_S2_DEVICE
