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
