• aaee2c94f   KVM: MMU: Switch to mmu spinlock ... Browse Code »

  Convert the synchronization of the shadow handling to a separate mmu_lock
  spinlock.

  Also guard fetch() by mmap_sem in read-mode to protect against alias
  and memslot changes.

• 10589a469   KVM: MMU: Concurrent guest walkers ... Browse Code »

  Do not hold kvm->lock mutex across the entire pagefault code,
  only acquire it in places where it is necessary, such as mmu
  hash list, active list, rmap and parent pte handling.

  Allow concurrent guest walkers by switching walk_addr() to use
  mmap_sem in read-mode.

  And get rid of the lockless __gfn_to_page.

  [avi: move kvm_mmu_pte_write() locking inside the function]
  [avi: add locking for real mode]
  [avi: fix cmpxchg locking]
