[PATCH v3 0/4] live migration dirty bitmap support for ARMv7

[Mario Smarduch]

Hi,
 this the third iteration of live migration support for the time being on 
ARMv7. The patches depend on Eric Augers patch for memory regions.

Changes since v2:
- move initial VM write protect to memory region architecture prepare function
  (needed to make dirty logging function generic) 
- added stage2_mark_pte_ro() - to mark ptes ro - Marc's comment
- optimized initial VM memory region write protect to do fewer table lookups -
  applied Marc's comment for walking dirty bitmap mask
- added pud_addr_end() for stage2 tables, to make the walk 4-level
- added kvm_flush_remote_tlbs() to use ARM TLB invalidation, made the generic
  one weak, Marc's comment to for generic dirty bitmap log function
- optimized walking dirty bit map mask to skip upper tables - Marc's comment
- deleted x86,arm kvm_vm_ioctl_get_dirty_log(), moved to kvm_main.c tagged 
  the function weak - Marc's comment
- changed Data Abort handler pte index handling - Marc's comment


Mario Smarduch (4):
  add ARMv7 HYP API to flush VM TLBs without address param
  live migration support for initial write protect of VM to track dirty
    pages
  live migration support for VM dirty log management
  add 2nd stage page fault handling during live migration
