Hi Radim and Paolo,

Here is the first small round of fixes for KVM/ARM for v4.19.  The
changes include:

 - Fix a VFP corruption in 32-bit guest
 - Add missing cache invalidation for CoW pages
 - Two small cleanups

Note that I have a question out on the CoW cache issue relating to
zero-page backed PMD mappings, but if there is any additional fixes to
be done, that doesn't invalidate the current patch and we can follow up
later.

The following changes since commit 5b394b2ddf0347bef56e50c69a58773c94343ff3:

  Linux 4.19-rc1 (2018-08-26 14:11:59 -0700)
