Move to SRCU to eliminate custom list walker, and optionally use
mmu_notifier in lieu of refcounting VMAs to avoid defining ->close.

v2: Rebase to latest master.

Sean Christopherson (2):
  x86/sgx: Use SRCU to protect mm_list during reclaim
  x86/sgx: Use mmu_notifier.release() instead of per-vma refcounting
